We look at the division of 868475 by 51 
Let's see how many times 51 fits into 868475.

Going ahead to step 1:
8 divided by 51 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 51

Advancing to step 2:
51 goes into 86 1 times with a remainder of 35.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 51 from 86 leaves us with 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 51

Step 3:
51 goes into 358 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 17.0
Deduct 357 from 358 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 51

Step 4:
51 can be fit into 14 0 times, resulting in a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 170.0
If we take 0 away from 14, we end up with 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 51

Advancing to step 5:
51 can be fit into 147 2 times, resulting in a remainder of 45.
The number 2 becomes the next digit in our result. 
Result so far: 1702.0
The remainder is 45 after subtracting 102 from 147.
Include the next digit (5) from the dividend after 45, then repeat: 455 / 51

Step 6:
51 goes into 455 8 times with a remainder of 47.
The next digit of our result is 8. 
Result so far: 17028.0
The remainder is 47 after subtracting 408 from 455.
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 7:
If we divide 470 by 51, we get 9 and a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 17028.9
If we subtract 459 from 470, we 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.

Let's proceed to step 8:
51 goes into 110 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 17028.92
If we take 102 away from 110, we end up 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.

Moving on to step 9:
51 goes into 80 1 times with a remainder of 29.
The next digit of our result is 1. 
Result so far: 17028.921
If we take 51 away from 80, we end up 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.

Moving on to step 10:
The number 51 fits into 290 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 17028.9215
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:
If we divide 350 by 51, we get 6 and a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 17028.92156
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.
Use 8 as the next digit of our solution. 
Result so far: 17028.921568
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.

Let's proceed to step 13:
320 divided by 51 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 17028.9215686
If we subtract 306 from 320, we 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.

Moving on to step 14:
If we divide 140 by 51, we get 2 and a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 17028.92156862
Subtracting 102 from 140 leaves us 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.

After the division, we end up with 17028.92156862 and a remainder of 3.8e-08.
