We're dividing 86198436 by 108 
Our goal is to divide 86198436 by 108.

Advancing to step 1:
108 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 108

Going ahead to step 2:
The number 108 fits into 86 0 times, leaving a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Append the next digit (1) from the dividend to 86 and continue with: 861 / 108

Let's proceed to step 3:
When dividing 861 by 108, we get 7 with a remainder of 105.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 756 from 861 and we're left with 105.
Fetch the next digit (9) from the dividend, attach it to 105 and continue: 1059 / 108

Moving on to step 4:
If we divide 1059 by 108, we get 9 and a remainder of 87.
Use 9 as the next digit of our solution. 
Result so far: 79.0
If we take 972 away from 1059, we end up with 87.
Append the next digit (8) from the dividend to 87 and continue with: 878 / 108

Let's proceed to step 5:
878 divided by 108 is 8 with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 798.0
The remainder is 14 after subtracting 864 from 878.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 108

Moving on to step 6:
144 divided by 108 is 1 with a remainder of 36.
The next digit of our result is 1. 
Result so far: 7981.0
If we take 108 away from 144, we end up with 36.
Append the next digit (3) from the dividend to 36 and continue with: 363 / 108

Step 7:
If we divide 363 by 108, we get 3 and a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 79813.0
If we subtract 324 from 363, we get 39.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 108

On to step 8:
108 can be fit into 396 3 times, resulting in a remainder of 72.
The number 3 becomes the next digit in our result. 
Result so far: 798133.0
Deduct 324 from 396 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 9:
108 goes into 720 6 times with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 798133.6
Subtracting 648 from 720 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 10:
108 goes into 720 6 times with a remainder of 72.
Use 6 as the next digit of our solution. 
Result so far: 798133.66
If we subtract 648 from 720, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

In conclusion, the division gives 798133.66 with a balance of 0.072.
