56215165 ÷ 688 
We're looking to find how many times 688 goes into 56215165.

On to step 1:
5 divided by 688 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 688

Going ahead to step 2:
56 divided by 688 is 0 with a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 56 to get 56.
Fetch the next digit (2) from the dividend, attach it to 56 and continue: 562 / 688

Advancing to step 3:
562 divided by 688 is 0 with a remainder of 562.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 562 leaves us with 562.
Append the next digit (1) from the dividend to 562 and continue with: 5621 / 688

Step 4:
688 can be fit into 5621 8 times, resulting in a remainder of 117.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 5504 away from 5621, we end up with 117.
Fetch the next digit (5) from the dividend, attach it to 117 and continue: 1175 / 688

Let's proceed to step 5:
When dividing 1175 by 688, we get 1 with a remainder of 487.
The next digit of our result is 1. 
Result so far: 81.0
Subtracting 688 from 1175 leaves us with 487.
Take the next digit (1) from the dividend and append it to 487, then repeat: 4871 / 688

Moving on to step 6:
When dividing 4871 by 688, we get 7 with a remainder of 55.
Record the quotient 7 as the next digit in the result. 
Result so far: 817.0
If we subtract 4816 from 4871, we get 55.
Fetch the next digit (6) from the dividend, attach it to 55 and continue: 556 / 688

Moving on to step 7:
The number 688 fits into 556 0 times, leaving a remainder of 556.
The next digit of our result is 0. 
Result so far: 8170.0
If we subtract 0 from 556, we get 556.
Bring next digit (5) of the dividend behind the 556 and repeat the process: 5565 / 688

Let's proceed to step 8:
5565 divided by 688 is 8 with a remainder of 61.
The next digit of our result is 8. 
Result so far: 81708.0
If we subtract 5504 from 5565, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Moving on to step 9:
688 can be fit into 610 0 times, resulting in a remainder of 610.
The number 0 becomes the next digit in our result. 
Result so far: 81708.0
Deduct 0 from 610 and we're left with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Moving on to step 10:
If we divide 6100 by 688, we get 8 and a remainder of 596.
The number 8 becomes the next digit in our result. 
Result so far: 81708.08
Deduct 5504 from 6100 and we're left with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Advancing to step 11:
5960 divided by 688 is 8 with a remainder of 456.
The next digit of our result is 8. 
Result so far: 81708.088
Deduct 5504 from 5960 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

After the division, we end up with 81708.088 and a remainder of 0.0456.
