We divide 775776 by 51
Let's see how many times 51 fits into 775776.

On to step 1:
If we divide 7 by 51, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 51

Advancing to step 2:
51 can be fit into 77 1 times, resulting in a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 51 from 77 and we're left with 26.
Include the next digit (5) from the dividend after 26, then repeat: 265 / 51

On to step 3:
51 goes into 265 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
The remainder is 10 after subtracting 255 from 265.
Grab the next digit (7) from the dividend, add it to 10, then carry on: 107 / 51

Going ahead to step 4:
107 divided by 51 is 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 152.0
If we subtract 102 from 107, we get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 51

On to step 5:
If we divide 57 by 51, we get 1 and a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1521.0
Subtract 51 from 57 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 51

Moving on to step 6:
51 goes into 66 1 times with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 15211.0
Subtract 51 from 66 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
150 divided by 51 is 2 with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 15211.2
Subtracting 102 from 150 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 8:
51 can be fit into 480 9 times, resulting in a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 15211.29
Subtract 459 from 480 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
The number 51 fits into 210 4 times, leaving a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 15211.294
If we take 204 away from 210, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
51 can be fit into 60 1 times, resulting in a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 15211.2941
The remainder is 9 after subtracting 51 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 11:
If we divide 90 by 51, we get 1 and a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 15211.29411
If we subtract 51 from 90, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 15211.29411 and a remainder of 3.9e-05.
