We look at the division of 212592 by 48 
We want to figure out the number of times 212592 can be divided by 48.

On to step 1:
48 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 48

On to step 2:
When dividing 21 by 48, we get 0 with a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 48

Step 3:
When dividing 212 by 48, we get 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 192 away from 212, we end up with 20.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 48

Let's proceed to step 4:
If we divide 205 by 48, we get 4 and a remainder of 13.
The next digit of our result is 4. 
Result so far: 44.0
If we take 192 away from 205, we end up with 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 48

Going ahead to step 5:
When dividing 139 by 48, we get 2 with a remainder of 43.
The number 2 becomes the next digit in our result. 
Result so far: 442.0
If we take 96 away from 139, we end up with 43.
Bring next digit (2) of the dividend behind the 43 and repeat the process: 432 / 48

On to step 6:
432 divided by 48 is 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 4429.0
If we subtract 432 from 432, we 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.

On to step 7:
When dividing 0 by 48, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 4429.0
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.

On to step 8:
The number 48 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 4429.0
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.

The quotient of the division is 4429.0, and the remainder is 0.0.
