We're dividing 14107644 by 721 
Our goal is to divide 14107644 by 721.

On to step 1:
The number 721 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 721

Moving on to step 2:
The number 721 fits into 14 0 times, leaving a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 721

Let's proceed to step 3:
141 divided by 721 is 0 with a remainder of 141.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 141 and we're left with 141.
Grab the next digit (0) from the dividend, add it to 141, then carry on: 1410 / 721

Step 4:
721 goes into 1410 1 times with a remainder of 689.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 721 from 1410 and we're left with 689.
Append the next digit (7) from the dividend to 689 and continue with: 6897 / 721

Going ahead to step 5:
When dividing 6897 by 721, we get 9 with a remainder of 408.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
If we take 6489 away from 6897, we end up with 408.
Bring next digit (6) of the dividend behind the 408 and repeat the process: 4086 / 721

Step 6:
If we divide 4086 by 721, we get 5 and a remainder of 481.
The next digit of our result is 5. 
Result so far: 195.0
If we subtract 3605 from 4086, we get 481.
Grab the next digit (4) from the dividend, add it to 481, then carry on: 4814 / 721

Advancing to step 7:
4814 divided by 721 is 6 with a remainder of 488.
The next digit of our result is 6. 
Result so far: 1956.0
Subtracting 4326 from 4814 leaves us with 488.
Bring next digit (4) of the dividend behind the 488 and repeat the process: 4884 / 721

On to step 8:
If we divide 4884 by 721, we get 6 and a remainder of 558.
Write down 6 as next digit of the result. 
Result so far: 19566.0
Subtracting 4326 from 4884 leaves us with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Let's proceed to step 9:
When dividing 5580 by 721, we get 7 with a remainder of 533.
The number 7 becomes the next digit in our result. 
Result so far: 19566.7
Deduct 5047 from 5580 and we're left with 533.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5330, and continue the process.

Advancing to step 10:
When dividing 5330 by 721, we get 7 with a remainder of 283.
Record the quotient 7 as the next digit in the result. 
Result so far: 19566.77
If we subtract 5047 from 5330, we get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

The final result is 19566.77 with a remainder of 0.283.
