Let's divide 71358072 by 51
We want to figure out the number of times 71358072 can be divided by 51.

Advancing to step 1:
The number 51 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 51

Let's proceed to step 2:
51 goes into 71 1 times with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 20 after subtracting 51 from 71.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 51

Going ahead to step 3:
The number 51 fits into 203 3 times, leaving a remainder of 50.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 153 away from 203, we end up with 50.
Fetch the next digit (5) from the dividend, attach it to 50 and continue: 505 / 51

Going ahead to step 4:
If we divide 505 by 51, we get 9 and a remainder of 46.
Write down 9 as next digit of the result. 
Result so far: 139.0
The remainder is 46 after subtracting 459 from 505.
Append the next digit (8) from the dividend to 46 and continue with: 468 / 51

Advancing to step 5:
If we divide 468 by 51, we get 9 and a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 1399.0
If we subtract 459 from 468, we get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 51

Step 6:
90 divided by 51 is 1 with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 13991.0
The remainder is 39 after subtracting 51 from 90.
Take the next digit (7) from the dividend and append it to 39, then repeat: 397 / 51

Moving on to step 7:
397 divided by 51 is 7 with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 139917.0
Subtracting 357 from 397 leaves us with 40.
Bring next digit (2) of the dividend behind the 40 and repeat the process: 402 / 51

Moving on to step 8:
If we divide 402 by 51, we get 7 and a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 1399177.0
The remainder is 45 after subtracting 357 from 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 9:
The number 51 fits into 450 8 times, leaving a remainder of 42.
The next digit of our result is 8. 
Result so far: 1399177.8
If we subtract 408 from 450, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 10:
The number 51 fits into 420 8 times, leaving a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 1399177.88
Deduct 408 from 420 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 1399177.88 with a remainder of 0.012.
