We're dividing 787464 by 51 
We want to divide 787464 by 51.

Step 1:
If we divide 7 by 51, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 51

Going ahead to step 2:
If we divide 78 by 51, we get 1 and a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 51 from 78, we get 27.
Bring next digit (7) of the dividend behind the 27 and repeat the process: 277 / 51

On to step 3:
51 goes into 277 5 times with a remainder of 22.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 22 after subtracting 255 from 277.
Bring next digit (4) of the dividend behind the 22 and repeat the process: 224 / 51

Going ahead to step 4:
The number 51 fits into 224 4 times, leaving a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 154.0
Subtract 204 from 224 to get 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 51

Going ahead to step 5:
When dividing 206 by 51, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 1544.0
If we subtract 204 from 206, we get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 51

Let's proceed to step 6:
The number 51 fits into 24 0 times, leaving a remainder of 24.
Record the quotient 0 as the next digit in the result. 
Result so far: 15440.0
Deduct 0 from 24 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
When dividing 240 by 51, we get 4 with a remainder of 36.
The number 4 becomes the next digit in our result. 
Result so far: 15440.4
If we subtract 204 from 240, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 8:
51 goes into 360 7 times with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 15440.47
The remainder is 3 after subtracting 357 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 9:
If we divide 30 by 51, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 15440.47
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
51 goes into 300 5 times with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 15440.4705
If we take 255 away from 300, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 11:
450 divided by 51 is 8 with a remainder of 42.
The next digit of our result is 8. 
Result so far: 15440.47058
Subtract 408 from 450 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 12:
420 divided by 51 is 8 with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 15440.470588
If we take 408 away from 420, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 15440.470588 and a remainder of 1.2e-06.
