687017 ÷ 51 
We want to divide 687017 by 51.

On to step 1:
51 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 51

Advancing to step 2:
51 goes into 68 1 times with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 51 from 68 and we're left with 17.
Append the next digit (7) from the dividend to 17 and continue with: 177 / 51

Step 3:
The number 51 fits into 177 3 times, leaving a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 153 away from 177, we end up with 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 51

On to step 4:
51 can be fit into 240 4 times, resulting in a remainder of 36.
The next digit of our result is 4. 
Result so far: 134.0
Deduct 204 from 240 and we're left with 36.
Append the next digit (1) from the dividend to 36 and continue with: 361 / 51

On to step 5:
51 goes into 361 7 times with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 1347.0
If we take 357 away from 361, we end up with 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 51

On to step 6:
If we divide 47 by 51, we get 0 and a remainder of 47.
Record the quotient 0 as the next digit in the result. 
Result so far: 13470.0
Subtracting 0 from 47 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.

Let's proceed to step 7:
470 divided by 51 is 9 with a remainder of 11.
The next digit of our result is 9. 
Result so far: 13470.9
Subtract 459 from 470 to get 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:
51 goes into 110 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 13470.92
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.

On to step 9:
The number 51 fits into 80 1 times, leaving a remainder of 29.
The next digit of our result is 1. 
Result so far: 13470.921
If we subtract 51 from 80, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 10:
If we divide 290 by 51, we get 5 and a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 13470.9215
Subtract 255 from 290 to 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 11:
When dividing 350 by 51, we get 6 with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 13470.92156
The remainder is 44 after subtracting 306 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 12:
If we divide 440 by 51, we get 8 and a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 13470.921568
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.

Moving on to step 13:
The number 51 fits into 320 6 times, leaving a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 13470.9215686
Subtract 306 from 320 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 14:
When dividing 140 by 51, we get 2 with a remainder of 38.
The next digit of our result is 2. 
Result so far: 13470.92156862
Deduct 102 from 140 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final result is 13470.92156862 with a remainder of 3.8e-08.
