85537521 divided by 108 
The aim is to understand the frequency of 108 in 85537521.

Going ahead to step 1:
When dividing 8 by 108, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 108

Step 2:
108 goes into 85 0 times with a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Append the next digit (5) from the dividend to 85 and continue with: 855 / 108

Step 3:
The number 108 fits into 855 7 times, leaving a remainder of 99.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 756 from 855 leaves us with 99.
Append the next digit (3) from the dividend to 99 and continue with: 993 / 108

Let's proceed to step 4:
108 goes into 993 9 times with a remainder of 21.
The next digit of our result is 9. 
Result so far: 79.0
If we subtract 972 from 993, we get 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 108

On to step 5:
217 divided by 108 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 792.0
Deduct 216 from 217 and we're left with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 108

Advancing to step 6:
The number 108 fits into 15 0 times, leaving a remainder of 15.
The next digit of our result is 0. 
Result so far: 7920.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (2) from the dividend, add it to 15, then carry on: 152 / 108

Let's proceed to step 7:
When dividing 152 by 108, we get 1 with a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 79201.0
If we take 108 away from 152, we end up with 44.
Grab the next digit (1) from the dividend, add it to 44, then carry on: 441 / 108

Let's proceed to step 8:
108 can be fit into 441 4 times, resulting in a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 792014.0
Subtracting 432 from 441 leaves us 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.

On to step 9:
If we divide 90 by 108, we get 0 and a remainder of 90.
Use 0 as the next digit of our solution. 
Result so far: 792014.0
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 10:
When dividing 900 by 108, we get 8 with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 792014.08
If we take 864 away from 900, we end up 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.

On to step 11:
108 goes into 360 3 times with a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 792014.083
The remainder is 36 after subtracting 324 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 12:
The number 108 fits into 360 3 times, leaving a remainder of 36.
Record the quotient 3 as the next digit in the result. 
Result so far: 792014.0833
If we subtract 324 from 360, we 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.

The final outcome is 792014.0833, with a leftover of 0.00036.
