We're dividing 771725 by 51 
Let's see how many times 51 fits into 771725.

Advancing to step 1:
7 divided by 51 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 51

Moving on to step 2:
The number 51 fits into 77 1 times, leaving a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 51 from 77 to get 26.
Append the next digit (1) from the dividend to 26 and continue with: 261 / 51

Let's proceed to step 3:
51 can be fit into 261 5 times, resulting in a remainder of 6.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 6 after subtracting 255 from 261.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 51

Step 4:
If we divide 67 by 51, we get 1 and a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 151.0
The remainder is 16 after subtracting 51 from 67.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 51

On to step 5:
The number 51 fits into 162 3 times, leaving a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 1513.0
The remainder is 9 after subtracting 153 from 162.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 51

Advancing to step 6:
If we divide 95 by 51, we get 1 and a remainder of 44.
The next digit of our result is 1. 
Result so far: 15131.0
Subtract 51 from 95 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
If we divide 440 by 51, we get 8 and a remainder of 32.
The next digit of our result is 8. 
Result so far: 15131.8
The remainder is 32 after subtracting 408 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 8:
51 can be fit into 320 6 times, resulting in a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 15131.86
Subtracting 306 from 320 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 9:
If we divide 140 by 51, we get 2 and a remainder of 38.
Put 2 as the next digit of the answer. 
Result so far: 15131.862
Subtract 102 from 140 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 10:
51 can be fit into 380 7 times, resulting in a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 15131.8627
If we subtract 357 from 380, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 11:
If we divide 230 by 51, we get 4 and a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 15131.86274
Subtracting 204 from 230 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 12:
If we divide 260 by 51, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 15131.862745
If we take 255 away from 260, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
The number 51 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 15131.862745
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 14:
500 divided by 51 is 9 with a remainder of 41.
Use 9 as the next digit of our solution. 
Result so far: 15131.86274509
Deduct 459 from 500 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

The final outcome is 15131.86274509, with a leftover of 4.1e-08.
