We're dividing 158592 by 63 
We're looking to find how many times 63 goes into 158592.

Step 1:
When dividing 1 by 63, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 63

On to step 2:
63 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 63

Step 3:
158 divided by 63 is 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 2.0
The remainder is 32 after subtracting 126 from 158.
Grab the next digit (5) from the dividend, add it to 32, then carry on: 325 / 63

Advancing to step 4:
63 can be fit into 325 5 times, resulting in a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 25.0
The remainder is 10 after subtracting 315 from 325.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 63

On to step 5:
The number 63 fits into 109 1 times, leaving a remainder of 46.
Put 1 as the next digit of the answer. 
Result so far: 251.0
Subtract 63 from 109 to get 46.
Bring next digit (2) of the dividend behind the 46 and repeat the process: 462 / 63

Step 6:
462 divided by 63 is 7 with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 2517.0
Subtracting 441 from 462 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
63 goes into 210 3 times with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 2517.3
Subtract 189 from 210 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 8:
210 divided by 63 is 3 with a remainder of 21.
The next digit of our result is 3. 
Result so far: 2517.33
If we subtract 189 from 210, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

After the division, we end up with 2517.33 and a remainder of 0.021.
