We look at the division of 87220580 by 688 
Let's see how many times 688 fits into 87220580.

Step 1:
688 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 688

Step 2:
The number 688 fits into 87 0 times, leaving a remainder of 87.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 87, we end up with 87.
Grab the next digit (2) from the dividend, add it to 87, then carry on: 872 / 688

Going ahead to step 3:
872 divided by 688 is 1 with a remainder of 184.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 688 from 872, we get 184.
Append the next digit (2) from the dividend to 184 and continue with: 1842 / 688

Let's proceed to step 4:
688 can be fit into 1842 2 times, resulting in a remainder of 466.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtracting 1376 from 1842 leaves us with 466.
Fetch the next digit (0) from the dividend, attach it to 466 and continue: 4660 / 688

Moving on to step 5:
If we divide 4660 by 688, we get 6 and a remainder of 532.
Write down 6 as next digit of the result. 
Result so far: 126.0
The remainder is 532 after subtracting 4128 from 4660.
Include the next digit (5) from the dividend after 532, then repeat: 5325 / 688

Moving on to step 6:
If we divide 5325 by 688, we get 7 and a remainder of 509.
Write down 7 as next digit of the result. 
Result so far: 1267.0
The remainder is 509 after subtracting 4816 from 5325.
Fetch the next digit (8) from the dividend, attach it to 509 and continue: 5098 / 688

Moving on to step 7:
When dividing 5098 by 688, we get 7 with a remainder of 282.
Put 7 as the next digit of the answer. 
Result so far: 12677.0
Deduct 4816 from 5098 and we're left with 282.
Bring next digit (0) of the dividend behind the 282 and repeat the process: 2820 / 688

Advancing to step 8:
2820 divided by 688 is 4 with a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 126774.0
Subtract 2752 from 2820 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 9:
680 divided by 688 is 0 with a remainder of 680.
Write down 0 as next digit of the result. 
Result so far: 126774.0
Subtracting 0 from 680 leaves us with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 10:
When dividing 6800 by 688, we get 9 with a remainder of 608.
The number 9 becomes the next digit in our result. 
Result so far: 126774.09
If we subtract 6192 from 6800, we get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Advancing to step 11:
When dividing 6080 by 688, we get 8 with a remainder of 576.
The next digit of our result is 8. 
Result so far: 126774.098
If we subtract 5504 from 6080, we get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Going ahead to step 12:
The number 688 fits into 5760 8 times, leaving a remainder of 256.
Put 8 as the next digit of the answer. 
Result so far: 126774.0988
The remainder is 256 after subtracting 5504 from 5760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Our division results in 126774.0988 with a remaining 0.00256.
