Let's divide 40293261 by 721
Our goal is to divide 40293261 by 721.

On to step 1:
721 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 721

Moving on to step 2:
721 can be fit into 40 0 times, resulting in a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Grab the next digit (2) from the dividend, add it to 40, then carry on: 402 / 721

Step 3:
721 can be fit into 402 0 times, resulting in a remainder of 402.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 402 and we're left with 402.
Append the next digit (9) from the dividend to 402 and continue with: 4029 / 721

Moving on to step 4:
721 goes into 4029 5 times with a remainder of 424.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 3605 from 4029, we get 424.
Grab the next digit (3) from the dividend, add it to 424, then carry on: 4243 / 721

Let's proceed to step 5:
The number 721 fits into 4243 5 times, leaving a remainder of 638.
Write down 5 as next digit of the result. 
Result so far: 55.0
The remainder is 638 after subtracting 3605 from 4243.
Include the next digit (2) from the dividend after 638, then repeat: 6382 / 721

Step 6:
6382 divided by 721 is 8 with a remainder of 614.
Record the quotient 8 as the next digit in the result. 
Result so far: 558.0
Subtract 5768 from 6382 to get 614.
Take the next digit (6) from the dividend and append it to 614, then repeat: 6146 / 721

Advancing to step 7:
721 can be fit into 6146 8 times, resulting in a remainder of 378.
Use 8 as the next digit of our solution. 
Result so far: 5588.0
Subtract 5768 from 6146 to get 378.
Bring next digit (1) of the dividend behind the 378 and repeat the process: 3781 / 721

Advancing to step 8:
3781 divided by 721 is 5 with a remainder of 176.
Write down 5 as next digit of the result. 
Result so far: 55885.0
If we take 3605 away from 3781, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 9:
721 goes into 1760 2 times with a remainder of 318.
Write down 2 as next digit of the result. 
Result so far: 55885.2
Subtracting 1442 from 1760 leaves us with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Let's proceed to step 10:
721 can be fit into 3180 4 times, resulting in a remainder of 296.
The next digit of our result is 4. 
Result so far: 55885.24
If we subtract 2884 from 3180, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Advancing to step 11:
2960 divided by 721 is 4 with a remainder of 76.
Put 4 as the next digit of the answer. 
Result so far: 55885.244
Subtracting 2884 from 2960 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Our division results in 55885.244 with a remaining 0.0076.
