Let's divide 51190085 by 720
Let's see how many times 720 fits into 51190085.

Step 1:
720 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 720

Going ahead to step 2:
720 goes into 51 0 times with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Append the next digit (1) from the dividend to 51 and continue with: 511 / 720

Let's proceed to step 3:
720 can be fit into 511 0 times, resulting in a remainder of 511.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 511, we get 511.
Fetch the next digit (9) from the dividend, attach it to 511 and continue: 5119 / 720

Let's proceed to step 4:
The number 720 fits into 5119 7 times, leaving a remainder of 79.
Write down 7 as next digit of the result. 
Result so far: 7.0
The remainder is 79 after subtracting 5040 from 5119.
Take the next digit (0) from the dividend and append it to 79, then repeat: 790 / 720

Let's proceed to step 5:
When dividing 790 by 720, we get 1 with a remainder of 70.
Write down 1 as next digit of the result. 
Result so far: 71.0
Deduct 720 from 790 and we're left with 70.
Fetch the next digit (0) from the dividend, attach it to 70 and continue: 700 / 720

On to step 6:
720 goes into 700 0 times with a remainder of 700.
Record the quotient 0 as the next digit in the result. 
Result so far: 710.0
If we subtract 0 from 700, we get 700.
Fetch the next digit (8) from the dividend, attach it to 700 and continue: 7008 / 720

Step 7:
When dividing 7008 by 720, we get 9 with a remainder of 528.
The number 9 becomes the next digit in our result. 
Result so far: 7109.0
Subtracting 6480 from 7008 leaves us with 528.
Fetch the next digit (5) from the dividend, attach it to 528 and continue: 5285 / 720

Advancing to step 8:
If we divide 5285 by 720, we get 7 and a remainder of 245.
The next digit of our result is 7. 
Result so far: 71097.0
Subtracting 5040 from 5285 leaves us with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Moving on to step 9:
The number 720 fits into 2450 3 times, leaving a remainder of 290.
The number 3 becomes the next digit in our result. 
Result so far: 71097.3
Subtracting 2160 from 2450 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 10:
720 can be fit into 2900 4 times, resulting in a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 71097.34
Subtracting 2880 from 2900 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.

Moving on to step 11:
720 can be fit into 200 0 times, resulting in a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 71097.34
If we take 0 away from 200, we end up 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.

Going ahead to step 12:
When dividing 2000 by 720, we get 2 with a remainder of 560.
Put 2 as the next digit of the answer. 
Result so far: 71097.3402
The remainder is 560 after subtracting 1440 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 13:
The number 720 fits into 5600 7 times, leaving a remainder of 560.
Record the quotient 7 as the next digit in the result. 
Result so far: 71097.34027
The remainder is 560 after subtracting 5040 from 5600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 14:
If we divide 5600 by 720, we get 7 and a remainder of 560.
Use 7 as the next digit of our solution. 
Result so far: 71097.340277
If we subtract 5040 from 5600, we 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.

The final result is 71097.340277 with a remainder of 5.6e-05.
