578238 ÷ 51 
We're looking to find how many times 51 goes into 578238.

Moving on to step 1:
The number 51 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 51

Advancing to step 2:
57 divided by 51 is 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 51 from 57 leaves us with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 51

Moving on to step 3:
When dividing 68 by 51, we get 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 51 from 68, we get 17.
Fetch the next digit (2) from the dividend, attach it to 17 and continue: 172 / 51

Moving on to step 4:
172 divided by 51 is 3 with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 113.0
If we subtract 153 from 172, we get 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 51

Going ahead to step 5:
51 can be fit into 193 3 times, resulting in a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 1133.0
Subtract 153 from 193 to get 40.
Include the next digit (8) from the dividend after 40, then repeat: 408 / 51

Moving on to step 6:
If we divide 408 by 51, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 11338.0
If we take 408 away from 408, 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.

Going ahead to step 7:
The number 51 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11338.0
Subtracting 0 from 0 leaves us 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 8:
0 divided by 51 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11338.0
Subtract 0 from 0 to get 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 quotient of the division is 11338.0, and the remainder is 0.0.
