Let's divide 159925 by 45
We're looking to find how many times 45 goes into 159925.

Advancing to step 1:
When dividing 1 by 45, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 45

Moving on to step 2:
15 divided by 45 is 0 with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 45

On to step 3:
159 divided by 45 is 3 with a remainder of 24.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 135 from 159, we get 24.
Include the next digit (9) from the dividend after 24, then repeat: 249 / 45

Moving on to step 4:
45 goes into 249 5 times with a remainder of 24.
Record the quotient 5 as the next digit in the result. 
Result so far: 35.0
Subtracting 225 from 249 leaves us with 24.
Fetch the next digit (2) from the dividend, attach it to 24 and continue: 242 / 45

Going ahead to step 5:
45 can be fit into 242 5 times, resulting in a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 355.0
Subtract 225 from 242 to get 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 45

Advancing to step 6:
175 divided by 45 is 3 with a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 3553.0
If we take 135 away from 175, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 7:
400 divided by 45 is 8 with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 3553.8
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
400 divided by 45 is 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 3553.88
The remainder is 40 after subtracting 360 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 3553.88, with a leftover of 0.04.
