We look at the division of 86663088 by 788 
We're looking to find how many times 788 goes into 86663088.

On to step 1:
788 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 788

Moving on to step 2:
The number 788 fits into 86 0 times, leaving a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 86 and we're left with 86.
Take the next digit (6) from the dividend and append it to 86, then repeat: 866 / 788

Let's proceed to step 3:
If we divide 866 by 788, we get 1 and a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 788 from 866 to get 78.
Take the next digit (6) from the dividend and append it to 78, then repeat: 786 / 788

Advancing to step 4:
788 goes into 786 0 times with a remainder of 786.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 786, we end up with 786.
Append the next digit (3) from the dividend to 786 and continue with: 7863 / 788

Step 5:
788 can be fit into 7863 9 times, resulting in a remainder of 771.
Put 9 as the next digit of the answer. 
Result so far: 109.0
Deduct 7092 from 7863 and we're left with 771.
Bring next digit (0) of the dividend behind the 771 and repeat the process: 7710 / 788

On to step 6:
When dividing 7710 by 788, we get 9 with a remainder of 618.
Put 9 as the next digit of the answer. 
Result so far: 1099.0
If we take 7092 away from 7710, we end up with 618.
Bring next digit (8) of the dividend behind the 618 and repeat the process: 6188 / 788

Going ahead to step 7:
788 can be fit into 6188 7 times, resulting in a remainder of 672.
Use 7 as the next digit of our solution. 
Result so far: 10997.0
Subtracting 5516 from 6188 leaves us with 672.
Bring next digit (8) of the dividend behind the 672 and repeat the process: 6728 / 788

Going ahead to step 8:
If we divide 6728 by 788, we get 8 and a remainder of 424.
Use 8 as the next digit of our solution. 
Result so far: 109978.0
Deduct 6304 from 6728 and we're left with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Going ahead to step 9:
When dividing 4240 by 788, we get 5 with a remainder of 300.
Put 5 as the next digit of the answer. 
Result so far: 109978.5
If we take 3940 away from 4240, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Advancing to step 10:
The number 788 fits into 3000 3 times, leaving a remainder of 636.
The number 3 becomes the next digit in our result. 
Result so far: 109978.53
Deduct 2364 from 3000 and we're left with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Step 11:
The number 788 fits into 6360 8 times, leaving a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 109978.538
Deduct 6304 from 6360 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 12:
788 can be fit into 560 0 times, resulting in a remainder of 560.
Use 0 as the next digit of our solution. 
Result so far: 109978.538
Subtract 0 from 560 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 13:
788 goes into 5600 7 times with a remainder of 84.
The number 7 becomes the next digit in our result. 
Result so far: 109978.53807
Subtracting 5516 from 5600 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

On to step 14:
When dividing 840 by 788, we get 1 with a remainder of 52.
Record the quotient 1 as the next digit in the result. 
Result so far: 109978.538071
Subtract 788 from 840 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 15:
788 goes into 520 0 times with a remainder of 520.
Write down 0 as next digit of the result. 
Result so far: 109978.538071
If we take 0 away from 520, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 16:
When dividing 5200 by 788, we get 6 with a remainder of 472.
The next digit of our result is 6. 
Result so far: 109978.53807106
Subtract 4728 from 5200 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

The final outcome is 109978.53807106, with a leftover of 4.72e-07.
