88931369 ÷ 857 
Our goal is to divide 88931369 by 857.

Moving on to step 1:
857 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 857

On to step 2:
857 goes into 88 0 times with a remainder of 88.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 88, we end up with 88.
Append the next digit (9) from the dividend to 88 and continue with: 889 / 857

Advancing to step 3:
857 can be fit into 889 1 times, resulting in a remainder of 32.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 857 from 889 to get 32.
Bring next digit (3) of the dividend behind the 32 and repeat the process: 323 / 857

Advancing to step 4:
When dividing 323 by 857, we get 0 with a remainder of 323.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 323 and we're left with 323.
Bring next digit (1) of the dividend behind the 323 and repeat the process: 3231 / 857

Step 5:
857 can be fit into 3231 3 times, resulting in a remainder of 660.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
Deduct 2571 from 3231 and we're left with 660.
Fetch the next digit (3) from the dividend, attach it to 660 and continue: 6603 / 857

Let's proceed to step 6:
6603 divided by 857 is 7 with a remainder of 604.
The next digit of our result is 7. 
Result so far: 1037.0
Subtract 5999 from 6603 to get 604.
Bring next digit (6) of the dividend behind the 604 and repeat the process: 6046 / 857

Step 7:
When dividing 6046 by 857, we get 7 with a remainder of 47.
Use 7 as the next digit of our solution. 
Result so far: 10377.0
If we take 5999 away from 6046, we end up with 47.
Append the next digit (9) from the dividend to 47 and continue with: 479 / 857

On to step 8:
When dividing 479 by 857, we get 0 with a remainder of 479.
Put 0 as the next digit of the answer. 
Result so far: 103770.0
Subtracting 0 from 479 leaves us with 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

Going ahead to step 9:
857 can be fit into 4790 5 times, resulting in a remainder of 505.
Record the quotient 5 as the next digit in the result. 
Result so far: 103770.5
If we take 4285 away from 4790, we end up with 505.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5050, and continue the process.

Going ahead to step 10:
5050 divided by 857 is 5 with a remainder of 765.
Use 5 as the next digit of our solution. 
Result so far: 103770.55
If we take 4285 away from 5050, we end up with 765.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7650, and continue the process.

After the division, we end up with 103770.55 and a remainder of 0.765.
