Let's divide 54121887 by 724
We want to divide 54121887 by 724.

On to step 1:
The number 724 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 724

Going ahead to step 2:
54 divided by 724 is 0 with a remainder of 54.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Include the next digit (1) from the dividend after 54, then repeat: 541 / 724

Step 3:
541 divided by 724 is 0 with a remainder of 541.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 541 and we're left with 541.
Grab the next digit (2) from the dividend, add it to 541, then carry on: 5412 / 724

Going ahead to step 4:
724 can be fit into 5412 7 times, resulting in a remainder of 344.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 5068 from 5412 leaves us with 344.
Append the next digit (1) from the dividend to 344 and continue with: 3441 / 724

Advancing to step 5:
If we divide 3441 by 724, we get 4 and a remainder of 545.
Use 4 as the next digit of our solution. 
Result so far: 74.0
Deduct 2896 from 3441 and we're left with 545.
Fetch the next digit (8) from the dividend, attach it to 545 and continue: 5458 / 724

Going ahead to step 6:
If we divide 5458 by 724, we get 7 and a remainder of 390.
Use 7 as the next digit of our solution. 
Result so far: 747.0
Deduct 5068 from 5458 and we're left with 390.
Fetch the next digit (8) from the dividend, attach it to 390 and continue: 3908 / 724

Step 7:
When dividing 3908 by 724, we get 5 with a remainder of 288.
Record the quotient 5 as the next digit in the result. 
Result so far: 7475.0
Deduct 3620 from 3908 and we're left with 288.
Grab the next digit (7) from the dividend, add it to 288, then carry on: 2887 / 724

On to step 8:
When dividing 2887 by 724, we get 3 with a remainder of 715.
The next digit of our result is 3. 
Result so far: 74753.0
The remainder is 715 after subtracting 2172 from 2887.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7150, and continue the process.

Step 9:
7150 divided by 724 is 9 with a remainder of 634.
Use 9 as the next digit of our solution. 
Result so far: 74753.9
The remainder is 634 after subtracting 6516 from 7150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6340, and continue the process.

Step 10:
When dividing 6340 by 724, we get 8 with a remainder of 548.
Write down 8 as next digit of the result. 
Result so far: 74753.98
Deduct 5792 from 6340 and we're left with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Let's proceed to step 11:
When dividing 5480 by 724, we get 7 with a remainder of 412.
Use 7 as the next digit of our solution. 
Result so far: 74753.987
Deduct 5068 from 5480 and we're left with 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Going ahead to step 12:
The number 724 fits into 4120 5 times, leaving a remainder of 500.
The number 5 becomes the next digit in our result. 
Result so far: 74753.9875
If we take 3620 away from 4120, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

On to step 13:
724 can be fit into 5000 6 times, resulting in a remainder of 656.
Write down 6 as next digit of the result. 
Result so far: 74753.98756
Subtracting 4344 from 5000 leaves us with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

Advancing to step 14:
724 goes into 6560 9 times with a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 74753.987569
If we take 6516 away from 6560, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 15:
When dividing 440 by 724, we get 0 with a remainder of 440.
Record the quotient 0 as the next digit in the result. 
Result so far: 74753.987569
Subtract 0 from 440 to get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 16:
724 goes into 4400 6 times with a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 74753.98756906
If we take 4344 away from 4400, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 74753.98756906 and a remainder of 5.6e-08.
