If we subtract 0 from 9, we get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 51

Step 2:
If we divide 97 by 51, we get 1 and a remainder of 46.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 51 from 97, we get 46.
Grab the next digit (3) from the dividend, add it to 46, then carry on: 463 / 51

Going ahead to step 3:
51 can be fit into 463 9 times, resulting in a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
Deduct 459 from 463 and we're left with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 51

Moving on to step 4:
46 divided by 51 is 0 with a remainder of 46.
The number 0 becomes the next digit in our result. 
Result so far: 190.0
Subtracting 0 from 46 leaves us with 46.
Fetch the next digit (5) from the dividend, attach it to 46 and continue: 465 / 51

Step 5:
The number 51 fits into 465 9 times, leaving a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 1909.0
Subtracting 459 from 465 leaves us with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 51

Let's proceed to step 6:
68 divided by 51 is 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 19091.0
If we take 51 away from 68, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
51 goes into 170 3 times with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 19091.3
Subtracting 153 from 170 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 8:
If we divide 170 by 51, we get 3 and a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 19091.33
Deduct 153 from 170 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Our division results in 19091.33 with a remaining 0.017.
