We look at the division of 86665389 by 657 
We want to divide 86665389 by 657.

On to step 1:
657 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 657

Let's proceed to step 2:
If we divide 86 by 657, we get 0 and a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Include the next digit (6) from the dividend after 86, then repeat: 866 / 657

Moving on to step 3:
The number 657 fits into 866 1 times, leaving a remainder of 209.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 209 after subtracting 657 from 866.
Bring next digit (6) of the dividend behind the 209 and repeat the process: 2096 / 657

Let's proceed to step 4:
The number 657 fits into 2096 3 times, leaving a remainder of 125.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 1971 away from 2096, we end up with 125.
Bring next digit (5) of the dividend behind the 125 and repeat the process: 1255 / 657

Moving on to step 5:
657 goes into 1255 1 times with a remainder of 598.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
Deduct 657 from 1255 and we're left with 598.
Append the next digit (3) from the dividend to 598 and continue with: 5983 / 657

Step 6:
657 goes into 5983 9 times with a remainder of 70.
Use 9 as the next digit of our solution. 
Result so far: 1319.0
Subtract 5913 from 5983 to get 70.
Include the next digit (8) from the dividend after 70, then repeat: 708 / 657

Going ahead to step 7:
708 divided by 657 is 1 with a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 13191.0
If we take 657 away from 708, we end up with 51.
Bring next digit (9) of the dividend behind the 51 and repeat the process: 519 / 657

Let's proceed to step 8:
If we divide 519 by 657, we get 0 and a remainder of 519.
The number 0 becomes the next digit in our result. 
Result so far: 131910.0
Subtracting 0 from 519 leaves us with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Moving on to step 9:
The number 657 fits into 5190 7 times, leaving a remainder of 591.
Write down 7 as next digit of the result. 
Result so far: 131910.7
Deduct 4599 from 5190 and we're left with 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

Moving on to step 10:
657 can be fit into 5910 8 times, resulting in a remainder of 654.
Use 8 as the next digit of our solution. 
Result so far: 131910.78
Subtracting 5256 from 5910 leaves us with 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Advancing to step 11:
6540 divided by 657 is 9 with a remainder of 627.
The next digit of our result is 9. 
Result so far: 131910.789
The remainder is 627 after subtracting 5913 from 6540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

Step 12:
When dividing 6270 by 657, we get 9 with a remainder of 357.
The number 9 becomes the next digit in our result. 
Result so far: 131910.7899
The remainder is 357 after subtracting 5913 from 6270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

In conclusion, the division gives 131910.7899 with a balance of 0.00357.
