We're dividing 13419552 by 686 
Our goal is to divide 13419552 by 686.

Step 1:
1 divided by 686 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 686

Advancing to step 2:
13 divided by 686 is 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 686

Step 3:
When dividing 134 by 686, we get 0 with a remainder of 134.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 134 after subtracting 0 from 134.
Grab the next digit (1) from the dividend, add it to 134, then carry on: 1341 / 686

Let's proceed to step 4:
If we divide 1341 by 686, we get 1 and a remainder of 655.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 686 from 1341 to get 655.
Fetch the next digit (9) from the dividend, attach it to 655 and continue: 6559 / 686

Going ahead to step 5:
6559 divided by 686 is 9 with a remainder of 385.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we take 6174 away from 6559, we end up with 385.
Bring next digit (5) of the dividend behind the 385 and repeat the process: 3855 / 686

Moving on to step 6:
686 can be fit into 3855 5 times, resulting in a remainder of 425.
Write down 5 as next digit of the result. 
Result so far: 195.0
Subtract 3430 from 3855 to get 425.
Fetch the next digit (5) from the dividend, attach it to 425 and continue: 4255 / 686

Step 7:
4255 divided by 686 is 6 with a remainder of 139.
Put 6 as the next digit of the answer. 
Result so far: 1956.0
If we subtract 4116 from 4255, we get 139.
Append the next digit (2) from the dividend to 139 and continue with: 1392 / 686

Moving on to step 8:
686 goes into 1392 2 times with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 19562.0
The remainder is 20 after subtracting 1372 from 1392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
686 goes into 200 0 times with a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 19562.0
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 10:
When dividing 2000 by 686, we get 2 with a remainder of 628.
The number 2 becomes the next digit in our result. 
Result so far: 19562.02
The remainder is 628 after subtracting 1372 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Moving on to step 11:
686 can be fit into 6280 9 times, resulting in a remainder of 106.
The next digit of our result is 9. 
Result so far: 19562.029
Subtracting 6174 from 6280 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 12:
The number 686 fits into 1060 1 times, leaving a remainder of 374.
Write down 1 as next digit of the result. 
Result so far: 19562.0291
The remainder is 374 after subtracting 686 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Step 13:
If we divide 3740 by 686, we get 5 and a remainder of 310.
The next digit of our result is 5. 
Result so far: 19562.02915
If we take 3430 away from 3740, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 14:
If we divide 3100 by 686, we get 4 and a remainder of 356.
Write down 4 as next digit of the result. 
Result so far: 19562.029154
Deduct 2744 from 3100 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Advancing to step 15:
686 goes into 3560 5 times with a remainder of 130.
Write down 5 as next digit of the result. 
Result so far: 19562.0291545
The remainder is 130 after subtracting 3430 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Moving on to step 16:
686 can be fit into 1300 1 times, resulting in a remainder of 614.
The number 1 becomes the next digit in our result. 
Result so far: 19562.02915451
Deduct 686 from 1300 and we're left with 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

The final outcome is 19562.02915451, with a leftover of 6.14e-07.
