Let's divide 43490731 by 721
We're looking to find how many times 721 goes into 43490731.

Step 1:
4 divided by 721 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 721

Step 2:
If we divide 43 by 721, we get 0 and a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Bring next digit (4) of the dividend behind the 43 and repeat the process: 434 / 721

Advancing to step 3:
If we divide 434 by 721, we get 0 and a remainder of 434.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 434 to get 434.
Fetch the next digit (9) from the dividend, attach it to 434 and continue: 4349 / 721

Going ahead to step 4:
721 can be fit into 4349 6 times, resulting in a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 4326 from 4349, we get 23.
Fetch the next digit (0) from the dividend, attach it to 23 and continue: 230 / 721

Let's proceed to step 5:
721 can be fit into 230 0 times, resulting in a remainder of 230.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
If we take 0 away from 230, we end up with 230.
Take the next digit (7) from the dividend and append it to 230, then repeat: 2307 / 721

Moving on to step 6:
721 can be fit into 2307 3 times, resulting in a remainder of 144.
Record the quotient 3 as the next digit in the result. 
Result so far: 603.0
Subtract 2163 from 2307 to get 144.
Take the next digit (3) from the dividend and append it to 144, then repeat: 1443 / 721

Advancing to step 7:
When dividing 1443 by 721, we get 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 6032.0
If we subtract 1442 from 1443, we get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 721

Advancing to step 8:
When dividing 11 by 721, we get 0 with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 60320.0
Subtract 0 from 11 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 9:
If we divide 110 by 721, we get 0 and a remainder of 110.
The number 0 becomes the next digit in our result. 
Result so far: 60320.0
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Step 10:
When dividing 1100 by 721, we get 1 with a remainder of 379.
Write down 1 as next digit of the result. 
Result so far: 60320.01
Deduct 721 from 1100 and we're left with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

On to step 11:
721 goes into 3790 5 times with a remainder of 185.
Put 5 as the next digit of the answer. 
Result so far: 60320.015
Subtracting 3605 from 3790 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 12:
721 can be fit into 1850 2 times, resulting in a remainder of 408.
Write down 2 as next digit of the result. 
Result so far: 60320.0152
Deduct 1442 from 1850 and we're left with 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Moving on to step 13:
When dividing 4080 by 721, we get 5 with a remainder of 475.
The number 5 becomes the next digit in our result. 
Result so far: 60320.01525
The remainder is 475 after subtracting 3605 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4750, and continue the process.

Going ahead to step 14:
4750 divided by 721 is 6 with a remainder of 424.
Record the quotient 6 as the next digit in the result. 
Result so far: 60320.015256
Deduct 4326 from 4750 and we're left with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Let's proceed to step 15:
When dividing 4240 by 721, we get 5 with a remainder of 635.
Write down 5 as next digit of the result. 
Result so far: 60320.0152565
If we subtract 3605 from 4240, we get 635.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6350, and continue the process.

Going ahead to step 16:
6350 divided by 721 is 8 with a remainder of 582.
Write down 8 as next digit of the result. 
Result so far: 60320.01525658
Subtract 5768 from 6350 to get 582.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5820, and continue the process.

The final outcome is 60320.01525658, with a leftover of 5.82e-07.
