We're dividing 67344430 by 411 
The aim is to understand the frequency of 411 in 67344430.

On to step 1:
If we divide 6 by 411, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 411

Let's proceed to step 2:
411 goes into 67 0 times with a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 67 after subtracting 0 from 67.
Grab the next digit (3) from the dividend, add it to 67, then carry on: 673 / 411

On to step 3:
The number 411 fits into 673 1 times, leaving a remainder of 262.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 262 after subtracting 411 from 673.
Include the next digit (4) from the dividend after 262, then repeat: 2624 / 411

Moving on to step 4:
If we divide 2624 by 411, we get 6 and a remainder of 158.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 2466 away from 2624, we end up with 158.
Bring next digit (4) of the dividend behind the 158 and repeat the process: 1584 / 411

Let's proceed to step 5:
The number 411 fits into 1584 3 times, leaving a remainder of 351.
The number 3 becomes the next digit in our result. 
Result so far: 163.0
Subtracting 1233 from 1584 leaves us with 351.
Bring next digit (4) of the dividend behind the 351 and repeat the process: 3514 / 411

Let's proceed to step 6:
The number 411 fits into 3514 8 times, leaving a remainder of 226.
Use 8 as the next digit of our solution. 
Result so far: 1638.0
If we take 3288 away from 3514, we end up with 226.
Grab the next digit (3) from the dividend, add it to 226, then carry on: 2263 / 411

Step 7:
If we divide 2263 by 411, we get 5 and a remainder of 208.
Record the quotient 5 as the next digit in the result. 
Result so far: 16385.0
Subtract 2055 from 2263 to get 208.
Append the next digit (0) from the dividend to 208 and continue with: 2080 / 411

Let's proceed to step 8:
The number 411 fits into 2080 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 163855.0
If we take 2055 away from 2080, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
The number 411 fits into 250 0 times, leaving a remainder of 250.
The number 0 becomes the next digit in our result. 
Result so far: 163855.0
If we subtract 0 from 250, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 10:
The number 411 fits into 2500 6 times, leaving a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 163855.06
If we take 2466 away from 2500, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 11:
The number 411 fits into 340 0 times, leaving a remainder of 340.
Write down 0 as next digit of the result. 
Result so far: 163855.06
If we take 0 away from 340, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 12:
The number 411 fits into 3400 8 times, leaving a remainder of 112.
Record the quotient 8 as the next digit in the result. 
Result so far: 163855.0608
If we subtract 3288 from 3400, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 13:
411 can be fit into 1120 2 times, resulting in a remainder of 298.
The number 2 becomes the next digit in our result. 
Result so far: 163855.06082
Subtract 822 from 1120 to get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Step 14:
The number 411 fits into 2980 7 times, leaving a remainder of 103.
Use 7 as the next digit of our solution. 
Result so far: 163855.060827
If we subtract 2877 from 2980, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Advancing to step 15:
1030 divided by 411 is 2 with a remainder of 208.
The number 2 becomes the next digit in our result. 
Result so far: 163855.0608272
Deduct 822 from 1030 and we're left with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 16:
If we divide 2080 by 411, we get 5 and a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 163855.06082725
If we subtract 2055 from 2080, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 163855.06082725 and a remainder of 2.5e-08.
