Let's divide 54132439 by 721
Let's see how many times 721 fits into 54132439.

Going ahead to step 1:
721 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 721

Moving on to step 2:
If we divide 54 by 721, we get 0 and a remainder of 54.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Grab the next digit (1) from the dividend, add it to 54, then carry on: 541 / 721

Going ahead to step 3:
When dividing 541 by 721, we get 0 with a remainder of 541.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 541 to get 541.
Include the next digit (3) from the dividend after 541, then repeat: 5413 / 721

Advancing to step 4:
721 goes into 5413 7 times with a remainder of 366.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 5047 from 5413 and we're left with 366.
Fetch the next digit (2) from the dividend, attach it to 366 and continue: 3662 / 721

Step 5:
721 goes into 3662 5 times with a remainder of 57.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
Subtract 3605 from 3662 to get 57.
Append the next digit (4) from the dividend to 57 and continue with: 574 / 721

Moving on to step 6:
The number 721 fits into 574 0 times, leaving a remainder of 574.
Put 0 as the next digit of the answer. 
Result so far: 750.0
If we subtract 0 from 574, we get 574.
Grab the next digit (3) from the dividend, add it to 574, then carry on: 5743 / 721

Step 7:
When dividing 5743 by 721, we get 7 with a remainder of 696.
The next digit of our result is 7. 
Result so far: 7507.0
If we take 5047 away from 5743, we end up with 696.
Bring next digit (9) of the dividend behind the 696 and repeat the process: 6969 / 721

Let's proceed to step 8:
The number 721 fits into 6969 9 times, leaving a remainder of 480.
Put 9 as the next digit of the answer. 
Result so far: 75079.0
Subtract 6489 from 6969 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 9:
721 goes into 4800 6 times with a remainder of 474.
The next digit of our result is 6. 
Result so far: 75079.6
Subtract 4326 from 4800 to get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Moving on to step 10:
721 goes into 4740 6 times with a remainder of 414.
Write down 6 as next digit of the result. 
Result so far: 75079.66
Subtracting 4326 from 4740 leaves us with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Our division results in 75079.66 with a remaining 0.414.
