86930299 ÷ 657 
Our goal is to divide 86930299 by 657.

On to step 1:
The number 657 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 657

Advancing to step 2:
657 goes into 86 0 times with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Take the next digit (9) from the dividend and append it to 86, then repeat: 869 / 657

On to step 3:
If we divide 869 by 657, we get 1 and a remainder of 212.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 212 after subtracting 657 from 869.
Grab the next digit (3) from the dividend, add it to 212, then carry on: 2123 / 657

Advancing to step 4:
If we divide 2123 by 657, we get 3 and a remainder of 152.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 1971 from 2123 and we're left with 152.
Fetch the next digit (0) from the dividend, attach it to 152 and continue: 1520 / 657

Advancing to step 5:
If we divide 1520 by 657, we get 2 and a remainder of 206.
The number 2 becomes the next digit in our result. 
Result so far: 132.0
Subtracting 1314 from 1520 leaves us with 206.
Include the next digit (2) from the dividend after 206, then repeat: 2062 / 657

Going ahead to step 6:
657 goes into 2062 3 times with a remainder of 91.
Use 3 as the next digit of our solution. 
Result so far: 1323.0
Subtracting 1971 from 2062 leaves us with 91.
Fetch the next digit (9) from the dividend, attach it to 91 and continue: 919 / 657

Step 7:
657 can be fit into 919 1 times, resulting in a remainder of 262.
Put 1 as the next digit of the answer. 
Result so far: 13231.0
If we take 657 away from 919, we end up with 262.
Fetch the next digit (9) from the dividend, attach it to 262 and continue: 2629 / 657

Advancing to step 8:
The number 657 fits into 2629 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 132314.0
Deduct 2628 from 2629 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
657 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 132314.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
100 divided by 657 is 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 132314.0
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 132314.0 and a remainder of 0.1.
