778160 ÷ 51 
Our goal is to divide 778160 by 51.

Moving on to step 1:
When dividing 7 by 51, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 51

On to step 2:
51 can be fit into 77 1 times, resulting in a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 51 away from 77, we end up with 26.
Include the next digit (8) from the dividend after 26, then repeat: 268 / 51

Advancing to step 3:
268 divided by 51 is 5 with a remainder of 13.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 255 from 268 and we're left with 13.
Append the next digit (1) from the dividend to 13 and continue with: 131 / 51

Going ahead to step 4:
51 can be fit into 131 2 times, resulting in a remainder of 29.
Write down 2 as next digit of the result. 
Result so far: 152.0
If we subtract 102 from 131, we get 29.
Take the next digit (6) from the dividend and append it to 29, then repeat: 296 / 51

Going ahead to step 5:
296 divided by 51 is 5 with a remainder of 41.
Use 5 as the next digit of our solution. 
Result so far: 1525.0
Subtracting 255 from 296 leaves us with 41.
Take the next digit (0) from the dividend and append it to 41, then repeat: 410 / 51

Going ahead to step 6:
When dividing 410 by 51, we get 8 with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 15258.0
Deduct 408 from 410 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
If we divide 20 by 51, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 15258.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
51 goes into 200 3 times with a remainder of 47.
Put 3 as the next digit of the answer. 
Result so far: 15258.03
Deduct 153 from 200 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 9:
When dividing 470 by 51, we get 9 with a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 15258.039
The remainder is 11 after subtracting 459 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
When dividing 110 by 51, we get 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 15258.0392
Subtracting 102 from 110 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
The number 51 fits into 80 1 times, leaving a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 15258.03921
The remainder is 29 after subtracting 51 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 12:
If we divide 290 by 51, we get 5 and a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 15258.039215
If we subtract 255 from 290, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 13:
350 divided by 51 is 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 15258.0392156
Deduct 306 from 350 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 14:
The number 51 fits into 440 8 times, leaving a remainder of 32.
The next digit of our result is 8. 
Result so far: 15258.03921568
If we subtract 408 from 440, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 15258.03921568, with a leftover of 3.2e-08.
