86156297 ÷ 243 
We're looking to find how many times 243 goes into 86156297.

Let's proceed to step 1:
The number 243 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 243

Going ahead to step 2:
86 divided by 243 is 0 with a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 86, we get 86.
Grab the next digit (1) from the dividend, add it to 86, then carry on: 861 / 243

On to step 3:
243 can be fit into 861 3 times, resulting in a remainder of 132.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 729 from 861 leaves us with 132.
Bring next digit (5) of the dividend behind the 132 and repeat the process: 1325 / 243

Moving on to step 4:
When dividing 1325 by 243, we get 5 with a remainder of 110.
The next digit of our result is 5. 
Result so far: 35.0
The remainder is 110 after subtracting 1215 from 1325.
Include the next digit (6) from the dividend after 110, then repeat: 1106 / 243

Going ahead to step 5:
243 can be fit into 1106 4 times, resulting in a remainder of 134.
The number 4 becomes the next digit in our result. 
Result so far: 354.0
If we subtract 972 from 1106, we get 134.
Bring next digit (2) of the dividend behind the 134 and repeat the process: 1342 / 243

Let's proceed to step 6:
1342 divided by 243 is 5 with a remainder of 127.
Put 5 as the next digit of the answer. 
Result so far: 3545.0
The remainder is 127 after subtracting 1215 from 1342.
Append the next digit (9) from the dividend to 127 and continue with: 1279 / 243

Let's proceed to step 7:
The number 243 fits into 1279 5 times, leaving a remainder of 64.
Write down 5 as next digit of the result. 
Result so far: 35455.0
The remainder is 64 after subtracting 1215 from 1279.
Fetch the next digit (7) from the dividend, attach it to 64 and continue: 647 / 243

Going ahead to step 8:
The number 243 fits into 647 2 times, leaving a remainder of 161.
Write down 2 as next digit of the result. 
Result so far: 354552.0
Subtracting 486 from 647 leaves us with 161.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

Going ahead to step 9:
When dividing 1610 by 243, we get 6 with a remainder of 152.
Write down 6 as next digit of the result. 
Result so far: 354552.6
If we take 1458 away from 1610, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 10:
The number 243 fits into 1520 6 times, leaving a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 354552.66
Subtracting 1458 from 1520 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

After the division, we end up with 354552.66 and a remainder of 0.062.
