810718 ÷ 51 
Let's see how many times 51 fits into 810718.

Moving on to step 1:
51 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 51

Step 2:
The number 51 fits into 81 1 times, leaving a remainder of 30.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 51 from 81 and we're left with 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 51

On to step 3:
If we divide 300 by 51, we get 5 and a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtracting 255 from 300 leaves us with 45.
Fetch the next digit (7) from the dividend, attach it to 45 and continue: 457 / 51

Advancing to step 4:
The number 51 fits into 457 8 times, leaving a remainder of 49.
Put 8 as the next digit of the answer. 
Result so far: 158.0
Subtracting 408 from 457 leaves us with 49.
Append the next digit (1) from the dividend to 49 and continue with: 491 / 51

Step 5:
491 divided by 51 is 9 with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 1589.0
If we subtract 459 from 491, we get 32.
Grab the next digit (8) from the dividend, add it to 32, then carry on: 328 / 51

Step 6:
51 goes into 328 6 times with a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 15896.0
If we subtract 306 from 328, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 7:
If we divide 220 by 51, we get 4 and a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 15896.4
If we take 204 away from 220, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
If we divide 160 by 51, we get 3 and a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 15896.43
The remainder is 7 after subtracting 153 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 9:
70 divided by 51 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 15896.431
Deduct 51 from 70 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 10:
190 divided by 51 is 3 with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 15896.4313
Subtract 153 from 190 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 11:
51 goes into 370 7 times with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 15896.43137
If we subtract 357 from 370, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 12:
130 divided by 51 is 2 with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 15896.431372
Subtract 102 from 130 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 13:
280 divided by 51 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 15896.4313725
Subtract 255 from 280 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 14:
The number 51 fits into 250 4 times, leaving a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 15896.43137254
If we subtract 204 from 250, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Our division results in 15896.43137254 with a remaining 4.6e-08.
