We're dividing 88691 by 85 
The aim is to understand the frequency of 85 in 88691.

On to step 1:
When dividing 8 by 85, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 85

Going ahead to step 2:
The number 85 fits into 88 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 3 after subtracting 85 from 88.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 85

On to step 3:
36 divided by 85 is 0 with a remainder of 36.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 36, we end up with 36.
Fetch the next digit (9) from the dividend, attach it to 36 and continue: 369 / 85

On to step 4:
The number 85 fits into 369 4 times, leaving a remainder of 29.
Put 4 as the next digit of the answer. 
Result so far: 104.0
Subtracting 340 from 369 leaves us with 29.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 85

Let's proceed to step 5:
291 divided by 85 is 3 with a remainder of 36.
The next digit of our result is 3. 
Result so far: 1043.0
Deduct 255 from 291 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 6:
The number 85 fits into 360 4 times, leaving a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 1043.4
If we subtract 340 from 360, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 7:
85 can be fit into 200 2 times, resulting in a remainder of 30.
The number 2 becomes the next digit in our result. 
Result so far: 1043.42
Subtract 170 from 200 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
85 can be fit into 300 3 times, resulting in a remainder of 45.
Write down 3 as next digit of the result. 
Result so far: 1043.423
If we take 255 away from 300, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 9:
If we divide 450 by 85, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 1043.4235
Subtract 425 from 450 to 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 10:
85 can be fit into 250 2 times, resulting in a remainder of 80.
Record the quotient 2 as the next digit in the result. 
Result so far: 1043.42352
If we subtract 170 from 250, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Step 11:
85 goes into 800 9 times with a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 1043.423529
If we take 765 away from 800, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
The number 85 fits into 350 4 times, leaving a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 1043.4235294
Deduct 340 from 350 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
85 goes into 100 1 times with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1043.42352941
The remainder is 15 after subtracting 85 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 1043.42352941, and the remainder is 1.5e-08.
