We divide 51057251 by 791
We're looking to find how many times 791 goes into 51057251.

On to step 1:
If we divide 5 by 791, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 791

Step 2:
The number 791 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
Subtract 0 from 51 to get 51.
Bring next digit (0) of the dividend behind the 51 and repeat the process: 510 / 791

Going ahead to step 3:
When dividing 510 by 791, we get 0 with a remainder of 510.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 510 and we're left with 510.
Bring next digit (5) of the dividend behind the 510 and repeat the process: 5105 / 791

Going ahead to step 4:
When dividing 5105 by 791, we get 6 with a remainder of 359.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 4746 from 5105 and we're left with 359.
Fetch the next digit (7) from the dividend, attach it to 359 and continue: 3597 / 791

On to step 5:
3597 divided by 791 is 4 with a remainder of 433.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
Subtract 3164 from 3597 to get 433.
Take the next digit (2) from the dividend and append it to 433, then repeat: 4332 / 791

Advancing to step 6:
791 can be fit into 4332 5 times, resulting in a remainder of 377.
Put 5 as the next digit of the answer. 
Result so far: 645.0
Subtracting 3955 from 4332 leaves us with 377.
Fetch the next digit (5) from the dividend, attach it to 377 and continue: 3775 / 791

On to step 7:
The number 791 fits into 3775 4 times, leaving a remainder of 611.
Use 4 as the next digit of our solution. 
Result so far: 6454.0
Subtract 3164 from 3775 to get 611.
Append the next digit (1) from the dividend to 611 and continue with: 6111 / 791

On to step 8:
When dividing 6111 by 791, we get 7 with a remainder of 574.
Put 7 as the next digit of the answer. 
Result so far: 64547.0
Deduct 5537 from 6111 and we're left with 574.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Going ahead to step 9:
If we divide 5740 by 791, we get 7 and a remainder of 203.
The next digit of our result is 7. 
Result so far: 64547.7
Subtract 5537 from 5740 to get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Let's proceed to step 10:
2030 divided by 791 is 2 with a remainder of 448.
Write down 2 as next digit of the result. 
Result so far: 64547.72
Subtract 1582 from 2030 to get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Step 11:
If we divide 4480 by 791, we get 5 and a remainder of 525.
Put 5 as the next digit of the answer. 
Result so far: 64547.725
If we take 3955 away from 4480, we end up with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Moving on to step 12:
5250 divided by 791 is 6 with a remainder of 504.
Write down 6 as next digit of the result. 
Result so far: 64547.7256
The remainder is 504 after subtracting 4746 from 5250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Going ahead to step 13:
5040 divided by 791 is 6 with a remainder of 294.
The number 6 becomes the next digit in our result. 
Result so far: 64547.72566
If we subtract 4746 from 5040, we get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

The final result is 64547.72566 with a remainder of 0.000294.
