Let's divide 51719212 by 720
We want to figure out the number of times 51719212 can be divided by 720.

Moving on to step 1:
If we divide 5 by 720, we get 0 and a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 720

Moving on to step 2:
The number 720 fits into 51 0 times, leaving a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Include the next digit (7) from the dividend after 51, then repeat: 517 / 720

On to step 3:
720 can be fit into 517 0 times, resulting in a remainder of 517.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 517 and we're left with 517.
Grab the next digit (1) from the dividend, add it to 517, then carry on: 5171 / 720

Let's proceed to step 4:
If we divide 5171 by 720, we get 7 and a remainder of 131.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 5040 from 5171 and we're left with 131.
Fetch the next digit (9) from the dividend, attach it to 131 and continue: 1319 / 720

Going ahead to step 5:
If we divide 1319 by 720, we get 1 and a remainder of 599.
The next digit of our result is 1. 
Result so far: 71.0
Subtract 720 from 1319 to get 599.
Grab the next digit (2) from the dividend, add it to 599, then carry on: 5992 / 720

Step 6:
If we divide 5992 by 720, we get 8 and a remainder of 232.
The next digit of our result is 8. 
Result so far: 718.0
Subtract 5760 from 5992 to get 232.
Bring next digit (1) of the dividend behind the 232 and repeat the process: 2321 / 720

Let's proceed to step 7:
The number 720 fits into 2321 3 times, leaving a remainder of 161.
Use 3 as the next digit of our solution. 
Result so far: 7183.0
Deduct 2160 from 2321 and we're left with 161.
Append the next digit (2) from the dividend to 161 and continue with: 1612 / 720

On to step 8:
The number 720 fits into 1612 2 times, leaving a remainder of 172.
Record the quotient 2 as the next digit in the result. 
Result so far: 71832.0
Subtract 1440 from 1612 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 9:
1720 divided by 720 is 2 with a remainder of 280.
The number 2 becomes the next digit in our result. 
Result so far: 71832.2
Subtract 1440 from 1720 to get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 10:
720 goes into 2800 3 times with a remainder of 640.
The number 3 becomes the next digit in our result. 
Result so far: 71832.23
The remainder is 640 after subtracting 2160 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 11:
The number 720 fits into 6400 8 times, leaving a remainder of 640.
Use 8 as the next digit of our solution. 
Result so far: 71832.238
Subtracting 5760 from 6400 leaves us with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

On to step 12:
720 goes into 6400 8 times with a remainder of 640.
The number 8 becomes the next digit in our result. 
Result so far: 71832.2388
If we subtract 5760 from 6400, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Our division results in 71832.2388 with a remaining 0.0064.
