We divide 51570065 by 779
We want to figure out the number of times 51570065 can be divided by 779.

Advancing to step 1:
If we divide 5 by 779, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 779

Advancing to step 2:
The number 779 fits into 51 0 times, leaving a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Include the next digit (5) from the dividend after 51, then repeat: 515 / 779

Going ahead to step 3:
515 divided by 779 is 0 with a remainder of 515.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 515 after subtracting 0 from 515.
Bring next digit (7) of the dividend behind the 515 and repeat the process: 5157 / 779

Moving on to step 4:
779 can be fit into 5157 6 times, resulting in a remainder of 483.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 483 after subtracting 4674 from 5157.
Grab the next digit (0) from the dividend, add it to 483, then carry on: 4830 / 779

Moving on to step 5:
If we divide 4830 by 779, we get 6 and a remainder of 156.
Use 6 as the next digit of our solution. 
Result so far: 66.0
If we take 4674 away from 4830, we end up with 156.
Bring next digit (0) of the dividend behind the 156 and repeat the process: 1560 / 779

Moving on to step 6:
779 can be fit into 1560 2 times, resulting in a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 662.0
Subtract 1558 from 1560 to get 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 779

Moving on to step 7:
When dividing 26 by 779, we get 0 with a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 6620.0
If we subtract 0 from 26, we get 26.
Fetch the next digit (5) from the dividend, attach it to 26 and continue: 265 / 779

On to step 8:
779 can be fit into 265 0 times, resulting in a remainder of 265.
Write down 0 as next digit of the result. 
Result so far: 66200.0
Subtracting 0 from 265 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Let's proceed to step 9:
If we divide 2650 by 779, we get 3 and a remainder of 313.
Put 3 as the next digit of the answer. 
Result so far: 66200.3
Subtracting 2337 from 2650 leaves us with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Advancing to step 10:
If we divide 3130 by 779, we get 4 and a remainder of 14.
The number 4 becomes the next digit in our result. 
Result so far: 66200.34
Subtract 3116 from 3130 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
779 can be fit into 140 0 times, resulting in a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 66200.34
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Advancing to step 12:
If we divide 1400 by 779, we get 1 and a remainder of 621.
The number 1 becomes the next digit in our result. 
Result so far: 66200.3401
Subtracting 779 from 1400 leaves us with 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

On to step 13:
779 can be fit into 6210 7 times, resulting in a remainder of 757.
The number 7 becomes the next digit in our result. 
Result so far: 66200.34017
The remainder is 757 after subtracting 5453 from 6210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7570, and continue the process.

Step 14:
If we divide 7570 by 779, we get 9 and a remainder of 559.
Use 9 as the next digit of our solution. 
Result so far: 66200.340179
If we take 7011 away from 7570, we end up with 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Step 15:
5590 divided by 779 is 7 with a remainder of 137.
The next digit of our result is 7. 
Result so far: 66200.3401797
If we take 5453 away from 5590, we end up with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Advancing to step 16:
779 goes into 1370 1 times with a remainder of 591.
Write down 1 as next digit of the result. 
Result so far: 66200.34017971
If we take 779 away from 1370, we end up with 591.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5910, and continue the process.

The final result is 66200.34017971 with a remainder of 5.91e-07.
