We look at the division of 75074752 by 721 
We want to divide 75074752 by 721.

Moving on to step 1:
If we divide 7 by 721, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 721

On to step 2:
721 can be fit into 75 0 times, resulting in a remainder of 75.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 75 to get 75.
Bring next digit (0) of the dividend behind the 75 and repeat the process: 750 / 721

Going ahead to step 3:
750 divided by 721 is 1 with a remainder of 29.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 721 from 750 and we're left with 29.
Bring next digit (7) of the dividend behind the 29 and repeat the process: 297 / 721

Advancing to step 4:
The number 721 fits into 297 0 times, leaving a remainder of 297.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 297, we get 297.
Fetch the next digit (4) from the dividend, attach it to 297 and continue: 2974 / 721

Step 5:
The number 721 fits into 2974 4 times, leaving a remainder of 90.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
The remainder is 90 after subtracting 2884 from 2974.
Fetch the next digit (7) from the dividend, attach it to 90 and continue: 907 / 721

Let's proceed to step 6:
907 divided by 721 is 1 with a remainder of 186.
The next digit of our result is 1. 
Result so far: 1041.0
Subtract 721 from 907 to get 186.
Grab the next digit (5) from the dividend, add it to 186, then carry on: 1865 / 721

On to step 7:
When dividing 1865 by 721, we get 2 with a remainder of 423.
Use 2 as the next digit of our solution. 
Result so far: 10412.0
Subtracting 1442 from 1865 leaves us with 423.
Include the next digit (2) from the dividend after 423, then repeat: 4232 / 721

Moving on to step 8:
If we divide 4232 by 721, we get 5 and a remainder of 627.
Record the quotient 5 as the next digit in the result. 
Result so far: 104125.0
Deduct 3605 from 4232 and we're left with 627.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

Advancing to step 9:
6270 divided by 721 is 8 with a remainder of 502.
Write down 8 as next digit of the result. 
Result so far: 104125.8
The remainder is 502 after subtracting 5768 from 6270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Moving on to step 10:
The number 721 fits into 5020 6 times, leaving a remainder of 694.
Write down 6 as next digit of the result. 
Result so far: 104125.86
If we take 4326 away from 5020, we end up with 694.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

Let's proceed to step 11:
If we divide 6940 by 721, we get 9 and a remainder of 451.
The number 9 becomes the next digit in our result. 
Result so far: 104125.869
The remainder is 451 after subtracting 6489 from 6940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Going ahead to step 12:
If we divide 4510 by 721, we get 6 and a remainder of 184.
Put 6 as the next digit of the answer. 
Result so far: 104125.8696
Subtracting 4326 from 4510 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 13:
The number 721 fits into 1840 2 times, leaving a remainder of 398.
Record the quotient 2 as the next digit in the result. 
Result so far: 104125.86962
Subtract 1442 from 1840 to get 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Let's proceed to step 14:
721 can be fit into 3980 5 times, resulting in a remainder of 375.
Write down 5 as next digit of the result. 
Result so far: 104125.869625
If we subtract 3605 from 3980, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Advancing to step 15:
When dividing 3750 by 721, we get 5 with a remainder of 145.
Write down 5 as next digit of the result. 
Result so far: 104125.8696255
Subtract 3605 from 3750 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

After the division, we end up with 104125.8696255 and a remainder of 1.45e-06.
