We're dividing 71253989 by 791 
We're looking to find how many times 791 goes into 71253989.

Moving on to step 1:
791 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 791

Going ahead to step 2:
If we divide 71 by 791, we get 0 and a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Bring next digit (2) of the dividend behind the 71 and repeat the process: 712 / 791

Moving on to step 3:
When dividing 712 by 791, we get 0 with a remainder of 712.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 712, we get 712.
Take the next digit (5) from the dividend and append it to 712, then repeat: 7125 / 791

Moving on to step 4:
791 can be fit into 7125 9 times, resulting in a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 7119 from 7125, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 791

Going ahead to step 5:
791 can be fit into 63 0 times, resulting in a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Subtracting 0 from 63 leaves us with 63.
Append the next digit (9) from the dividend to 63 and continue with: 639 / 791

Moving on to step 6:
791 can be fit into 639 0 times, resulting in a remainder of 639.
The number 0 becomes the next digit in our result. 
Result so far: 900.0
The remainder is 639 after subtracting 0 from 639.
Append the next digit (8) from the dividend to 639 and continue with: 6398 / 791

Step 7:
6398 divided by 791 is 8 with a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 9008.0
If we subtract 6328 from 6398, we get 70.
Take the next digit (9) from the dividend and append it to 70, then repeat: 709 / 791

Going ahead to step 8:
When dividing 709 by 791, we get 0 with a remainder of 709.
The next digit of our result is 0. 
Result so far: 90080.0
If we subtract 0 from 709, we get 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

Moving on to step 9:
791 can be fit into 7090 8 times, resulting in a remainder of 762.
Use 8 as the next digit of our solution. 
Result so far: 90080.8
Subtracting 6328 from 7090 leaves us with 762.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7620, and continue the process.

On to step 10:
791 goes into 7620 9 times with a remainder of 501.
Put 9 as the next digit of the answer. 
Result so far: 90080.89
If we subtract 7119 from 7620, we get 501.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5010, and continue the process.

On to step 11:
5010 divided by 791 is 6 with a remainder of 264.
Put 6 as the next digit of the answer. 
Result so far: 90080.896
If we take 4746 away from 5010, we end up with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Step 12:
791 goes into 2640 3 times with a remainder of 267.
The number 3 becomes the next digit in our result. 
Result so far: 90080.8963
If we take 2373 away from 2640, we end up with 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Let's proceed to step 13:
If we divide 2670 by 791, we get 3 and a remainder of 297.
The next digit of our result is 3. 
Result so far: 90080.89633
Deduct 2373 from 2670 and we're left with 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

The final result is 90080.89633 with a remainder of 0.000297.
