996591 ÷ 51 
Let's see how many times 51 fits into 996591.

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
The remainder is 9 after subtracting 0 from 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 51

Moving on to step 2:
51 can be fit into 99 1 times, resulting in a remainder of 48.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 51 from 99, we get 48.
Grab the next digit (6) from the dividend, add it to 48, then carry on: 486 / 51

On to step 3:
486 divided by 51 is 9 with a remainder of 27.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 459 from 486 and we're left with 27.
Take the next digit (5) from the dividend and append it to 27, then repeat: 275 / 51

On to step 4:
When dividing 275 by 51, we get 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 195.0
The remainder is 20 after subtracting 255 from 275.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 51

Going ahead to step 5:
51 goes into 209 4 times with a remainder of 5.
Put 4 as the next digit of the answer. 
Result so far: 1954.0
Subtracting 204 from 209 leaves us with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 51

Step 6:
51 goes into 51 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 19541.0
Deduct 51 from 51 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
If we divide 0 by 51, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 19541.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
If we divide 0 by 51, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 19541.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 19541.0 with a remainder of 0.0.
