51621140 divided by 720 
We're looking to find how many times 720 goes into 51621140.

Advancing to step 1:
When dividing 5 by 720, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 720

Advancing to step 2:
720 can be fit into 51 0 times, resulting in a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Take the next digit (6) from the dividend and append it to 51, then repeat: 516 / 720

On to step 3:
720 can be fit into 516 0 times, resulting in a remainder of 516.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 516 leaves us with 516.
Include the next digit (2) from the dividend after 516, then repeat: 5162 / 720

Going ahead to step 4:
The number 720 fits into 5162 7 times, leaving a remainder of 122.
The next digit of our result is 7. 
Result so far: 7.0
The remainder is 122 after subtracting 5040 from 5162.
Bring next digit (1) of the dividend behind the 122 and repeat the process: 1221 / 720

Step 5:
The number 720 fits into 1221 1 times, leaving a remainder of 501.
Write down 1 as next digit of the result. 
Result so far: 71.0
Deduct 720 from 1221 and we're left with 501.
Bring next digit (1) of the dividend behind the 501 and repeat the process: 5011 / 720

Moving on to step 6:
5011 divided by 720 is 6 with a remainder of 691.
Use 6 as the next digit of our solution. 
Result so far: 716.0
Subtract 4320 from 5011 to get 691.
Fetch the next digit (4) from the dividend, attach it to 691 and continue: 6914 / 720

Going ahead to step 7:
When dividing 6914 by 720, we get 9 with a remainder of 434.
Record the quotient 9 as the next digit in the result. 
Result so far: 7169.0
Subtracting 6480 from 6914 leaves us with 434.
Fetch the next digit (0) from the dividend, attach it to 434 and continue: 4340 / 720

Advancing to step 8:
The number 720 fits into 4340 6 times, leaving a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 71696.0
Subtracting 4320 from 4340 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
The number 720 fits into 200 0 times, leaving a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 71696.0
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 10:
2000 divided by 720 is 2 with a remainder of 560.
Record the quotient 2 as the next digit in the result. 
Result so far: 71696.02
Deduct 1440 from 2000 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Going ahead to step 11:
720 goes into 5600 7 times with a remainder of 560.
The number 7 becomes the next digit in our result. 
Result so far: 71696.027
Subtract 5040 from 5600 to get 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Moving on to step 12:
The number 720 fits into 5600 7 times, leaving a remainder of 560.
Use 7 as the next digit of our solution. 
Result so far: 71696.0277
Deduct 5040 from 5600 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

The quotient of the division is 71696.0277, and the remainder is 0.0056.
