We're dividing 109042 by 25 
Our goal is to divide 109042 by 25.

Going ahead to step 1:
The number 25 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 25

Let's proceed to step 2:
10 divided by 25 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 10, we end up with 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 25

Moving on to step 3:
If we divide 109 by 25, we get 4 and a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 100 away from 109, we end up with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 25

Step 4:
25 can be fit into 90 3 times, resulting in a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 43.0
Deduct 75 from 90 and we're left with 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 25

Advancing to step 5:
154 divided by 25 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 436.0
If we take 150 away from 154, we end up with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 25

On to step 6:
When dividing 42 by 25, we get 1 with a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 4361.0
If we take 25 away from 42, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
When dividing 170 by 25, we get 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 4361.6
The remainder is 20 after subtracting 150 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
When dividing 200 by 25, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 4361.68
If we take 200 away from 200, 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.

Moving on to step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4361.68
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.

Advancing to step 10:
25 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4361.68
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.

After the division, we end up with 4361.68 and a remainder of 0.0.
