We're dividing 781316 by 51 
We're looking to find how many times 51 goes into 781316.

Let's proceed to step 1:
When dividing 7 by 51, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 51

Moving on to step 2:
When dividing 78 by 51, we get 1 with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 27 after subtracting 51 from 78.
Bring next digit (1) of the dividend behind the 27 and repeat the process: 271 / 51

Moving on to step 3:
51 goes into 271 5 times with a remainder of 16.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 16 after subtracting 255 from 271.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 51

On to step 4:
The number 51 fits into 163 3 times, leaving a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 153.0
If we subtract 153 from 163, we get 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 51

Going ahead to step 5:
51 can be fit into 101 1 times, resulting in a remainder of 50.
The number 1 becomes the next digit in our result. 
Result so far: 1531.0
Subtract 51 from 101 to get 50.
Fetch the next digit (6) from the dividend, attach it to 50 and continue: 506 / 51

On to step 6:
If we divide 506 by 51, we get 9 and a remainder of 47.
The next digit of our result is 9. 
Result so far: 15319.0
Subtracting 459 from 506 leaves us 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.

Advancing to step 7:
When dividing 470 by 51, we get 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 15319.9
Subtracting 459 from 470 leaves us with 11.
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 8:
110 divided by 51 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 15319.92
The remainder is 8 after subtracting 102 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
When dividing 80 by 51, we get 1 with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 15319.921
Deduct 51 from 80 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 10:
51 goes into 290 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 15319.9215
The remainder is 35 after subtracting 255 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 11:
If we divide 350 by 51, we get 6 and a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 15319.92156
Subtract 306 from 350 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.

On to step 12:
440 divided by 51 is 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 15319.921568
Subtract 408 from 440 to 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.

Moving on to step 13:
The number 51 fits into 320 6 times, leaving a remainder of 14.
The next digit of our result is 6. 
Result so far: 15319.9215686
The remainder is 14 after subtracting 306 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 14:
51 goes into 140 2 times with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 15319.92156862
The remainder is 38 after subtracting 102 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 15319.92156862, and the remainder is 3.8e-08.
