We look at the division of 13639776 by 684 
We want to figure out the number of times 13639776 can be divided by 684.

Step 1:
The number 684 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 684

Advancing to step 2:
The number 684 fits into 13 0 times, leaving a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Bring next digit (6) of the dividend behind the 13 and repeat the process: 136 / 684

On to step 3:
136 divided by 684 is 0 with a remainder of 136.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 136 to get 136.
Take the next digit (3) from the dividend and append it to 136, then repeat: 1363 / 684

Moving on to step 4:
1363 divided by 684 is 1 with a remainder of 679.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 684 from 1363 leaves us with 679.
Grab the next digit (9) from the dividend, add it to 679, then carry on: 6799 / 684

On to step 5:
684 can be fit into 6799 9 times, resulting in a remainder of 643.
Write down 9 as next digit of the result. 
Result so far: 19.0
The remainder is 643 after subtracting 6156 from 6799.
Append the next digit (7) from the dividend to 643 and continue with: 6437 / 684

On to step 6:
6437 divided by 684 is 9 with a remainder of 281.
Use 9 as the next digit of our solution. 
Result so far: 199.0
Deduct 6156 from 6437 and we're left with 281.
Fetch the next digit (7) from the dividend, attach it to 281 and continue: 2817 / 684

On to step 7:
684 goes into 2817 4 times with a remainder of 81.
Use 4 as the next digit of our solution. 
Result so far: 1994.0
Subtracting 2736 from 2817 leaves us with 81.
Include the next digit (6) from the dividend after 81, then repeat: 816 / 684

Advancing to step 8:
684 can be fit into 816 1 times, resulting in a remainder of 132.
The next digit of our result is 1. 
Result so far: 19941.0
Subtracting 684 from 816 leaves us with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Step 9:
684 goes into 1320 1 times with a remainder of 636.
Write down 1 as next digit of the result. 
Result so far: 19941.1
Deduct 684 from 1320 and we're left with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Advancing to step 10:
When dividing 6360 by 684, we get 9 with a remainder of 204.
Record the quotient 9 as the next digit in the result. 
Result so far: 19941.19
If we subtract 6156 from 6360, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

On to step 11:
684 goes into 2040 2 times with a remainder of 672.
The number 2 becomes the next digit in our result. 
Result so far: 19941.192
If we take 1368 away from 2040, we end up with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Moving on to step 12:
684 can be fit into 6720 9 times, resulting in a remainder of 564.
The number 9 becomes the next digit in our result. 
Result so far: 19941.1929
If we take 6156 away from 6720, we end up with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Moving on to step 13:
If we divide 5640 by 684, we get 8 and a remainder of 168.
Put 8 as the next digit of the answer. 
Result so far: 19941.19298
Subtract 5472 from 5640 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 14:
The number 684 fits into 1680 2 times, leaving a remainder of 312.
Use 2 as the next digit of our solution. 
Result so far: 19941.192982
The remainder is 312 after subtracting 1368 from 1680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Advancing to step 15:
The number 684 fits into 3120 4 times, leaving a remainder of 384.
Record the quotient 4 as the next digit in the result. 
Result so far: 19941.1929824
If we subtract 2736 from 3120, we get 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 16:
684 goes into 3840 5 times with a remainder of 420.
The number 5 becomes the next digit in our result. 
Result so far: 19941.19298245
Subtracting 3420 from 3840 leaves us with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

The quotient of the division is 19941.19298245, and the remainder is 4.2e-07.
