We divide 641561 by 67
The aim is to understand the frequency of 67 in 641561.

On to step 1:
When dividing 6 by 67, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 67

Going ahead to step 2:
If we divide 64 by 67, we get 0 and a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Grab the next digit (1) from the dividend, add it to 64, then carry on: 641 / 67

On to step 3:
When dividing 641 by 67, we get 9 with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 38 after subtracting 603 from 641.
Bring next digit (5) of the dividend behind the 38 and repeat the process: 385 / 67

Moving on to step 4:
The number 67 fits into 385 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 95.0
If we subtract 335 from 385, we get 50.
Take the next digit (6) from the dividend and append it to 50, then repeat: 506 / 67

On to step 5:
If we divide 506 by 67, we get 7 and a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 957.0
If we take 469 away from 506, we end up with 37.
Fetch the next digit (1) from the dividend, attach it to 37 and continue: 371 / 67

Let's proceed to step 6:
When dividing 371 by 67, we get 5 with a remainder of 36.
Use 5 as the next digit of our solution. 
Result so far: 9575.0
Subtract 335 from 371 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 7:
The number 67 fits into 360 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 9575.5
If we subtract 335 from 360, 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.

On to step 8:
67 goes into 250 3 times with a remainder of 49.
The next digit of our result is 3. 
Result so far: 9575.53
If we take 201 away from 250, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
67 goes into 490 7 times with a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 9575.537
If we take 469 away from 490, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 10:
If we divide 210 by 67, we get 3 and a remainder of 9.
The next digit of our result is 3. 
Result so far: 9575.5373
If we take 201 away from 210, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 11:
If we divide 90 by 67, we get 1 and a remainder of 23.
Write down 1 as next digit of the result. 
Result so far: 9575.53731
If we subtract 67 from 90, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 12:
230 divided by 67 is 3 with a remainder of 29.
The number 3 becomes the next digit in our result. 
Result so far: 9575.537313
Deduct 201 from 230 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 13:
67 goes into 290 4 times with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 9575.5373134
If we take 268 away from 290, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 14:
67 can be fit into 220 3 times, resulting in a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 9575.53731343
Deduct 201 from 220 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 9575.53731343, with a leftover of 1.9e-08.
