We divide 86736902 by 486
We want to figure out the number of times 86736902 can be divided by 486.

Advancing to step 1:
When dividing 8 by 486, we get 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 486

Going ahead to step 2:
486 goes into 86 0 times with a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Grab the next digit (7) from the dividend, add it to 86, then carry on: 867 / 486

Going ahead to step 3:
486 can be fit into 867 1 times, resulting in a remainder of 381.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 486 from 867 to get 381.
Include the next digit (3) from the dividend after 381, then repeat: 3813 / 486

On to step 4:
486 goes into 3813 7 times with a remainder of 411.
The next digit of our result is 7. 
Result so far: 17.0
Subtract 3402 from 3813 to get 411.
Bring next digit (6) of the dividend behind the 411 and repeat the process: 4116 / 486

On to step 5:
486 goes into 4116 8 times with a remainder of 228.
The number 8 becomes the next digit in our result. 
Result so far: 178.0
Subtracting 3888 from 4116 leaves us with 228.
Append the next digit (9) from the dividend to 228 and continue with: 2289 / 486

Advancing to step 6:
The number 486 fits into 2289 4 times, leaving a remainder of 345.
The number 4 becomes the next digit in our result. 
Result so far: 1784.0
If we take 1944 away from 2289, we end up with 345.
Append the next digit (0) from the dividend to 345 and continue with: 3450 / 486

Moving on to step 7:
The number 486 fits into 3450 7 times, leaving a remainder of 48.
Write down 7 as next digit of the result. 
Result so far: 17847.0
Subtracting 3402 from 3450 leaves us with 48.
Append the next digit (2) from the dividend to 48 and continue with: 482 / 486

Step 8:
486 goes into 482 0 times with a remainder of 482.
Write down 0 as next digit of the result. 
Result so far: 178470.0
If we subtract 0 from 482, we get 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Advancing to step 9:
If we divide 4820 by 486, we get 9 and a remainder of 446.
Put 9 as the next digit of the answer. 
Result so far: 178470.9
Subtracting 4374 from 4820 leaves us with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Moving on to step 10:
4460 divided by 486 is 9 with a remainder of 86.
Write down 9 as next digit of the result. 
Result so far: 178470.99
The remainder is 86 after subtracting 4374 from 4460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final result is 178470.99 with a remainder of 0.086.
