We're dividing 993168 by 51 
We want to divide 993168 by 51.

Step 1:
51 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 51

Advancing to step 2:
When dividing 99 by 51, we get 1 with a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 48 after subtracting 51 from 99.
Bring next digit (3) of the dividend behind the 48 and repeat the process: 483 / 51

Step 3:
51 can be fit into 483 9 times, resulting in a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 459 from 483 to get 24.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 51

Let's proceed to step 4:
When dividing 241 by 51, we get 4 with a remainder of 37.
Use 4 as the next digit of our solution. 
Result so far: 194.0
The remainder is 37 after subtracting 204 from 241.
Include the next digit (6) from the dividend after 37, then repeat: 376 / 51

On to step 5:
If we divide 376 by 51, we get 7 and a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 1947.0
Deduct 357 from 376 and we're left with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 51

Going ahead to step 6:
51 goes into 198 3 times with a remainder of 45.
Use 3 as the next digit of our solution. 
Result so far: 19473.0
Subtract 153 from 198 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 7:
The number 51 fits into 450 8 times, leaving a remainder of 42.
The next digit of our result is 8. 
Result so far: 19473.8
Deduct 408 from 450 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
51 goes into 420 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 19473.88
Deduct 408 from 420 and we're left 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.

Our division results in 19473.88 with a remaining 0.012.
