We're dividing 52538666 by 721 
We want to divide 52538666 by 721.

Step 1:
721 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 721

Moving on to step 2:
If we divide 52 by 721, we get 0 and a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 52 after subtracting 0 from 52.
Fetch the next digit (5) from the dividend, attach it to 52 and continue: 525 / 721

Step 3:
525 divided by 721 is 0 with a remainder of 525.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 525, we end up with 525.
Append the next digit (3) from the dividend to 525 and continue with: 5253 / 721

Going ahead to step 4:
5253 divided by 721 is 7 with a remainder of 206.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 5047 from 5253 to get 206.
Fetch the next digit (8) from the dividend, attach it to 206 and continue: 2068 / 721

Let's proceed to step 5:
If we divide 2068 by 721, we get 2 and a remainder of 626.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
If we subtract 1442 from 2068, we get 626.
Fetch the next digit (6) from the dividend, attach it to 626 and continue: 6266 / 721

Step 6:
6266 divided by 721 is 8 with a remainder of 498.
Record the quotient 8 as the next digit in the result. 
Result so far: 728.0
If we subtract 5768 from 6266, we get 498.
Fetch the next digit (6) from the dividend, attach it to 498 and continue: 4986 / 721

Moving on to step 7:
The number 721 fits into 4986 6 times, leaving a remainder of 660.
Write down 6 as next digit of the result. 
Result so far: 7286.0
Subtracting 4326 from 4986 leaves us with 660.
Append the next digit (6) from the dividend to 660 and continue with: 6606 / 721

Step 8:
721 goes into 6606 9 times with a remainder of 117.
The next digit of our result is 9. 
Result so far: 72869.0
Deduct 6489 from 6606 and we're left with 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Advancing to step 9:
721 can be fit into 1170 1 times, resulting in a remainder of 449.
Use 1 as the next digit of our solution. 
Result so far: 72869.1
If we take 721 away from 1170, we end up with 449.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4490, and continue the process.

Step 10:
When dividing 4490 by 721, we get 6 with a remainder of 164.
Put 6 as the next digit of the answer. 
Result so far: 72869.16
If we subtract 4326 from 4490, we get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 11:
The number 721 fits into 1640 2 times, leaving a remainder of 198.
The next digit of our result is 2. 
Result so far: 72869.162
If we take 1442 away from 1640, we end up with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Going ahead to step 12:
When dividing 1980 by 721, we get 2 with a remainder of 538.
Record the quotient 2 as the next digit in the result. 
Result so far: 72869.1622
The remainder is 538 after subtracting 1442 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5380, and continue the process.

Our division results in 72869.1622 with a remaining 0.00538.
