57884204 ÷ 686 
Our goal is to divide 57884204 by 686.

On to step 1:
686 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 686

Let's proceed to step 2:
57 divided by 686 is 0 with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Grab the next digit (8) from the dividend, add it to 57, then carry on: 578 / 686

Going ahead to step 3:
686 goes into 578 0 times with a remainder of 578.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 578 leaves us with 578.
Include the next digit (8) from the dividend after 578, then repeat: 5788 / 686

Step 4:
5788 divided by 686 is 8 with a remainder of 300.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 5488 from 5788 and we're left with 300.
Grab the next digit (4) from the dividend, add it to 300, then carry on: 3004 / 686

Advancing to step 5:
686 can be fit into 3004 4 times, resulting in a remainder of 260.
Put 4 as the next digit of the answer. 
Result so far: 84.0
Subtract 2744 from 3004 to get 260.
Take the next digit (2) from the dividend and append it to 260, then repeat: 2602 / 686

Going ahead to step 6:
686 goes into 2602 3 times with a remainder of 544.
The next digit of our result is 3. 
Result so far: 843.0
If we take 2058 away from 2602, we end up with 544.
Grab the next digit (0) from the dividend, add it to 544, then carry on: 5440 / 686

On to step 7:
686 can be fit into 5440 7 times, resulting in a remainder of 638.
Write down 7 as next digit of the result. 
Result so far: 8437.0
If we take 4802 away from 5440, we end up with 638.
Bring next digit (4) of the dividend behind the 638 and repeat the process: 6384 / 686

Moving on to step 8:
When dividing 6384 by 686, we get 9 with a remainder of 210.
Put 9 as the next digit of the answer. 
Result so far: 84379.0
Subtract 6174 from 6384 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 9:
2100 divided by 686 is 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 84379.3
Deduct 2058 from 2100 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 10:
686 can be fit into 420 0 times, resulting in a remainder of 420.
Put 0 as the next digit of the answer. 
Result so far: 84379.3
The remainder is 420 after subtracting 0 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

On to step 11:
When dividing 4200 by 686, we get 6 with a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 84379.306
Subtracting 4116 from 4200 leaves us with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 12:
The number 686 fits into 840 1 times, leaving a remainder of 154.
Use 1 as the next digit of our solution. 
Result so far: 84379.3061
If we take 686 away from 840, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Moving on to step 13:
1540 divided by 686 is 2 with a remainder of 168.
The number 2 becomes the next digit in our result. 
Result so far: 84379.30612
Subtracting 1372 from 1540 leaves us with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

On to step 14:
If we divide 1680 by 686, we get 2 and a remainder of 308.
Use 2 as the next digit of our solution. 
Result so far: 84379.306122
If we subtract 1372 from 1680, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

The quotient of the division is 84379.306122, and the remainder is 3.08e-05.
