Let's divide 6721995 by 518
Let's see how many times 518 fits into 6721995.

Advancing to step 1:
The number 518 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 518

Step 2:
518 can be fit into 67 0 times, resulting in a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Bring next digit (2) of the dividend behind the 67 and repeat the process: 672 / 518

On to step 3:
If we divide 672 by 518, we get 1 and a remainder of 154.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 518 from 672 to get 154.
Take the next digit (1) from the dividend and append it to 154, then repeat: 1541 / 518

On to step 4:
When dividing 1541 by 518, we get 2 with a remainder of 505.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 1036 from 1541 and we're left with 505.
Include the next digit (9) from the dividend after 505, then repeat: 5059 / 518

Moving on to step 5:
If we divide 5059 by 518, we get 9 and a remainder of 397.
Put 9 as the next digit of the answer. 
Result so far: 129.0
If we take 4662 away from 5059, we end up with 397.
Include the next digit (9) from the dividend after 397, then repeat: 3979 / 518

Going ahead to step 6:
3979 divided by 518 is 7 with a remainder of 353.
Put 7 as the next digit of the answer. 
Result so far: 1297.0
Deduct 3626 from 3979 and we're left with 353.
Grab the next digit (5) from the dividend, add it to 353, then carry on: 3535 / 518

On to step 7:
If we divide 3535 by 518, we get 6 and a remainder of 427.
The number 6 becomes the next digit in our result. 
Result so far: 12976.0
If we take 3108 away from 3535, we end up with 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

Moving on to step 8:
518 can be fit into 4270 8 times, resulting in a remainder of 126.
Use 8 as the next digit of our solution. 
Result so far: 12976.8
The remainder is 126 after subtracting 4144 from 4270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Let's proceed to step 9:
The number 518 fits into 1260 2 times, leaving a remainder of 224.
The next digit of our result is 2. 
Result so far: 12976.82
If we take 1036 away from 1260, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Step 10:
When dividing 2240 by 518, we get 4 with a remainder of 168.
Write down 4 as next digit of the result. 
Result so far: 12976.824
If we subtract 2072 from 2240, we 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.

On to step 11:
518 can be fit into 1680 3 times, resulting in a remainder of 126.
The number 3 becomes the next digit in our result. 
Result so far: 12976.8243
If we subtract 1554 from 1680, we get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 12:
518 goes into 1260 2 times with a remainder of 224.
Use 2 as the next digit of our solution. 
Result so far: 12976.82432
If we subtract 1036 from 1260, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

On to step 13:
If we divide 2240 by 518, we get 4 and a remainder of 168.
Use 4 as the next digit of our solution. 
Result so far: 12976.824324
If we take 2072 away from 2240, we end up 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:
1680 divided by 518 is 3 with a remainder of 126.
The next digit of our result is 3. 
Result so far: 12976.8243243
Deduct 1554 from 1680 and we're left with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 15:
1260 divided by 518 is 2 with a remainder of 224.
The next digit of our result is 2. 
Result so far: 12976.82432432
Deduct 1036 from 1260 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

The final result is 12976.82432432 with a remainder of 2.24e-07.
