We're dividing 53039360 by 721 
We want to divide 53039360 by 721.

Advancing to step 1:
When dividing 5 by 721, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 721

On to step 2:
53 divided by 721 is 0 with a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Take the next digit (0) from the dividend and append it to 53, then repeat: 530 / 721

Advancing to step 3:
721 goes into 530 0 times with a remainder of 530.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 530 after subtracting 0 from 530.
Include the next digit (3) from the dividend after 530, then repeat: 5303 / 721

Going ahead to step 4:
If we divide 5303 by 721, we get 7 and a remainder of 256.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 5047 from 5303 to get 256.
Grab the next digit (9) from the dividend, add it to 256, then carry on: 2569 / 721

Step 5:
721 can be fit into 2569 3 times, resulting in a remainder of 406.
Put 3 as the next digit of the answer. 
Result so far: 73.0
The remainder is 406 after subtracting 2163 from 2569.
Grab the next digit (3) from the dividend, add it to 406, then carry on: 4063 / 721

On to step 6:
4063 divided by 721 is 5 with a remainder of 458.
Write down 5 as next digit of the result. 
Result so far: 735.0
The remainder is 458 after subtracting 3605 from 4063.
Grab the next digit (6) from the dividend, add it to 458, then carry on: 4586 / 721

Moving on to step 7:
721 can be fit into 4586 6 times, resulting in a remainder of 260.
Use 6 as the next digit of our solution. 
Result so far: 7356.0
The remainder is 260 after subtracting 4326 from 4586.
Bring next digit (0) of the dividend behind the 260 and repeat the process: 2600 / 721

On to step 8:
If we divide 2600 by 721, we get 3 and a remainder of 437.
The number 3 becomes the next digit in our result. 
Result so far: 73563.0
If we subtract 2163 from 2600, we get 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Advancing to step 9:
If we divide 4370 by 721, we get 6 and a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 73563.6
The remainder is 44 after subtracting 4326 from 4370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 10:
When dividing 440 by 721, we get 0 with a remainder of 440.
Put 0 as the next digit of the answer. 
Result so far: 73563.6
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.

Step 11:
721 goes into 4400 6 times with a remainder of 74.
The next digit of our result is 6. 
Result so far: 73563.606
Subtracting 4326 from 4400 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 12:
721 can be fit into 740 1 times, resulting in a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 73563.6061
Deduct 721 from 740 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 13:
If we divide 190 by 721, we get 0 and a remainder of 190.
The number 0 becomes the next digit in our result. 
Result so far: 73563.6061
Deduct 0 from 190 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 14:
721 goes into 1900 2 times with a remainder of 458.
Record the quotient 2 as the next digit in the result. 
Result so far: 73563.606102
If we take 1442 away from 1900, we end up with 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Step 15:
The number 721 fits into 4580 6 times, leaving a remainder of 254.
Write down 6 as next digit of the result. 
Result so far: 73563.6061026
Deduct 4326 from 4580 and we're left with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Going ahead to step 16:
721 can be fit into 2540 3 times, resulting in a remainder of 377.
Write down 3 as next digit of the result. 
Result so far: 73563.60610263
Deduct 2163 from 2540 and we're left with 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

The quotient of the division is 73563.60610263, and the remainder is 3.77e-07.
