56572397 ÷ 686 
Our goal is to divide 56572397 by 686.

Step 1:
686 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 686

Step 2:
When dividing 56 by 686, we get 0 with a remainder of 56.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 56 and we're left with 56.
Include the next digit (5) from the dividend after 56, then repeat: 565 / 686

Moving on to step 3:
When dividing 565 by 686, we get 0 with a remainder of 565.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 565 after subtracting 0 from 565.
Take the next digit (7) from the dividend and append it to 565, then repeat: 5657 / 686

Let's proceed to step 4:
The number 686 fits into 5657 8 times, leaving a remainder of 169.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 5488 from 5657 to get 169.
Take the next digit (2) from the dividend and append it to 169, then repeat: 1692 / 686

On to step 5:
686 goes into 1692 2 times with a remainder of 320.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
Subtracting 1372 from 1692 leaves us with 320.
Append the next digit (3) from the dividend to 320 and continue with: 3203 / 686

On to step 6:
686 goes into 3203 4 times with a remainder of 459.
Use 4 as the next digit of our solution. 
Result so far: 824.0
Subtract 2744 from 3203 to get 459.
Grab the next digit (9) from the dividend, add it to 459, then carry on: 4599 / 686

Moving on to step 7:
The number 686 fits into 4599 6 times, leaving a remainder of 483.
Write down 6 as next digit of the result. 
Result so far: 8246.0
Subtract 4116 from 4599 to get 483.
Fetch the next digit (7) from the dividend, attach it to 483 and continue: 4837 / 686

Advancing to step 8:
686 goes into 4837 7 times with a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 82467.0
The remainder is 35 after subtracting 4802 from 4837.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
The number 686 fits into 350 0 times, leaving a remainder of 350.
The next digit of our result is 0. 
Result so far: 82467.0
Deduct 0 from 350 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 10:
If we divide 3500 by 686, we get 5 and a remainder of 70.
The next digit of our result is 5. 
Result so far: 82467.05
Subtract 3430 from 3500 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 11:
If we divide 700 by 686, we get 1 and a remainder of 14.
The next digit of our result is 1. 
Result so far: 82467.051
The remainder is 14 after subtracting 686 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 12:
686 can be fit into 140 0 times, resulting in a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 82467.051
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 13:
If we divide 1400 by 686, we get 2 and a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 82467.05102
Deduct 1372 from 1400 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 14:
When dividing 280 by 686, we get 0 with a remainder of 280.
The number 0 becomes the next digit in our result. 
Result so far: 82467.05102
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 15:
686 can be fit into 2800 4 times, resulting in a remainder of 56.
Record the quotient 4 as the next digit in the result. 
Result so far: 82467.0510204
If we take 2744 away from 2800, we end up 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 16:
686 can be fit into 560 0 times, resulting in a remainder of 560.
Write down 0 as next digit of the result. 
Result so far: 82467.0510204
The remainder is 560 after subtracting 0 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Our division results in 82467.0510204 with a remaining 5.6e-07.
