We look at the division of 40357433 by 721 
Our goal is to divide 40357433 by 721.

Step 1:
When dividing 4 by 721, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 721

Let's proceed to step 2:
721 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Append the next digit (3) from the dividend to 40 and continue with: 403 / 721

Step 3:
When dividing 403 by 721, we get 0 with a remainder of 403.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 403 to get 403.
Append the next digit (5) from the dividend to 403 and continue with: 4035 / 721

Step 4:
When dividing 4035 by 721, we get 5 with a remainder of 430.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 3605 from 4035 and we're left with 430.
Fetch the next digit (7) from the dividend, attach it to 430 and continue: 4307 / 721

Let's proceed to step 5:
When dividing 4307 by 721, we get 5 with a remainder of 702.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
Subtracting 3605 from 4307 leaves us with 702.
Grab the next digit (4) from the dividend, add it to 702, then carry on: 7024 / 721

Advancing to step 6:
When dividing 7024 by 721, we get 9 with a remainder of 535.
Use 9 as the next digit of our solution. 
Result so far: 559.0
Deduct 6489 from 7024 and we're left with 535.
Grab the next digit (3) from the dividend, add it to 535, then carry on: 5353 / 721

Going ahead to step 7:
If we divide 5353 by 721, we get 7 and a remainder of 306.
The next digit of our result is 7. 
Result so far: 5597.0
If we take 5047 away from 5353, we end up with 306.
Take the next digit (3) from the dividend and append it to 306, then repeat: 3063 / 721

Going ahead to step 8:
721 goes into 3063 4 times with a remainder of 179.
Put 4 as the next digit of the answer. 
Result so far: 55974.0
If we subtract 2884 from 3063, we get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Going ahead to step 9:
721 can be fit into 1790 2 times, resulting in a remainder of 348.
The number 2 becomes the next digit in our result. 
Result so far: 55974.2
If we subtract 1442 from 1790, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 10:
721 goes into 3480 4 times with a remainder of 596.
Write down 4 as next digit of the result. 
Result so far: 55974.24
Deduct 2884 from 3480 and we're left with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Advancing to step 11:
5960 divided by 721 is 8 with a remainder of 192.
Write down 8 as next digit of the result. 
Result so far: 55974.248
If we take 5768 away from 5960, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 12:
1920 divided by 721 is 2 with a remainder of 478.
Record the quotient 2 as the next digit in the result. 
Result so far: 55974.2482
The remainder is 478 after subtracting 1442 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Advancing to step 13:
721 goes into 4780 6 times with a remainder of 454.
Put 6 as the next digit of the answer. 
Result so far: 55974.24826
Subtract 4326 from 4780 to get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Step 14:
721 can be fit into 4540 6 times, resulting in a remainder of 214.
Record the quotient 6 as the next digit in the result. 
Result so far: 55974.248266
Subtracting 4326 from 4540 leaves us with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

The quotient of the division is 55974.248266, and the remainder is 2.14e-05.
