409933 divided by 68 
The aim is to understand the frequency of 68 in 409933.

On to step 1:
68 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 68

On to step 2:
If we divide 40 by 68, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Fetch the next digit (9) from the dividend, attach it to 40 and continue: 409 / 68

Going ahead to step 3:
If we divide 409 by 68, we get 6 and a remainder of 1.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 408 from 409 and we're left with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 68

Advancing to step 4:
When dividing 19 by 68, we get 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 60.0
Subtracting 0 from 19 leaves us with 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 68

Let's proceed to step 5:
When dividing 193 by 68, we get 2 with a remainder of 57.
The number 2 becomes the next digit in our result. 
Result so far: 602.0
Subtract 136 from 193 to get 57.
Grab the next digit (3) from the dividend, add it to 57, then carry on: 573 / 68

Step 6:
68 can be fit into 573 8 times, resulting in a remainder of 29.
Put 8 as the next digit of the answer. 
Result so far: 6028.0
Subtract 544 from 573 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
68 goes into 290 4 times with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 6028.4
If we subtract 272 from 290, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
68 goes into 180 2 times with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 6028.42
Subtract 136 from 180 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 9:
If we divide 440 by 68, we get 6 and a remainder of 32.
The next digit of our result is 6. 
Result so far: 6028.426
If we take 408 away from 440, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
320 divided by 68 is 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 6028.4264
Subtracting 272 from 320 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
If we divide 480 by 68, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 6028.42647
If we subtract 476 from 480, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 12:
The number 68 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 6028.42647
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
68 goes into 400 5 times with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 6028.4264705
Deduct 340 from 400 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 14:
If we divide 600 by 68, we get 8 and a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 6028.42647058
The remainder is 56 after subtracting 544 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Our division results in 6028.42647058 with a remaining 5.6e-08.
