51680169 divided by 791 
Our goal is to divide 51680169 by 791.

Moving on to step 1:
5 divided by 791 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 791

Advancing to step 2:
791 goes into 51 0 times with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Grab the next digit (6) from the dividend, add it to 51, then carry on: 516 / 791

Moving on to step 3:
791 can be fit into 516 0 times, resulting in a remainder of 516.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 516, we end up with 516.
Grab the next digit (8) from the dividend, add it to 516, then carry on: 5168 / 791

Step 4:
791 goes into 5168 6 times with a remainder of 422.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 4746 from 5168, we get 422.
Take the next digit (0) from the dividend and append it to 422, then repeat: 4220 / 791

Going ahead to step 5:
791 goes into 4220 5 times with a remainder of 265.
Put 5 as the next digit of the answer. 
Result so far: 65.0
Subtract 3955 from 4220 to get 265.
Include the next digit (1) from the dividend after 265, then repeat: 2651 / 791

Let's proceed to step 6:
2651 divided by 791 is 3 with a remainder of 278.
The next digit of our result is 3. 
Result so far: 653.0
Deduct 2373 from 2651 and we're left with 278.
Include the next digit (6) from the dividend after 278, then repeat: 2786 / 791

On to step 7:
791 goes into 2786 3 times with a remainder of 413.
The number 3 becomes the next digit in our result. 
Result so far: 6533.0
Deduct 2373 from 2786 and we're left with 413.
Append the next digit (9) from the dividend to 413 and continue with: 4139 / 791

Let's proceed to step 8:
When dividing 4139 by 791, we get 5 with a remainder of 184.
Put 5 as the next digit of the answer. 
Result so far: 65335.0
If we subtract 3955 from 4139, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 9:
791 goes into 1840 2 times with a remainder of 258.
Use 2 as the next digit of our solution. 
Result so far: 65335.2
Subtract 1582 from 1840 to get 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Going ahead to step 10:
If we divide 2580 by 791, we get 3 and a remainder of 207.
Record the quotient 3 as the next digit in the result. 
Result so far: 65335.23
Subtract 2373 from 2580 to get 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Going ahead to step 11:
2070 divided by 791 is 2 with a remainder of 488.
The number 2 becomes the next digit in our result. 
Result so far: 65335.232
Subtract 1582 from 2070 to get 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Advancing to step 12:
When dividing 4880 by 791, we get 6 with a remainder of 134.
Use 6 as the next digit of our solution. 
Result so far: 65335.2326
If we take 4746 away from 4880, we end up with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Step 13:
791 can be fit into 1340 1 times, resulting in a remainder of 549.
The number 1 becomes the next digit in our result. 
Result so far: 65335.23261
Subtracting 791 from 1340 leaves us with 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

On to step 14:
791 can be fit into 5490 6 times, resulting in a remainder of 744.
Record the quotient 6 as the next digit in the result. 
Result so far: 65335.232616
Deduct 4746 from 5490 and we're left with 744.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7440, and continue the process.

On to step 15:
The number 791 fits into 7440 9 times, leaving a remainder of 321.
The next digit of our result is 9. 
Result so far: 65335.2326169
Deduct 7119 from 7440 and we're left with 321.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3210, and continue the process.

Step 16:
The number 791 fits into 3210 4 times, leaving a remainder of 46.
The next digit of our result is 4. 
Result so far: 65335.23261694
Subtracting 3164 from 3210 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final result is 65335.23261694 with a remainder of 4.6e-08.
