We're dividing 104372 by 45 
We want to figure out the number of times 104372 can be divided by 45.

Going ahead to step 1:
The number 45 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 45

On to step 2:
When dividing 10 by 45, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 45

Advancing to step 3:
When dividing 104 by 45, we get 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 90 from 104 and we're left with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 45

Advancing to step 4:
When dividing 143 by 45, we get 3 with a remainder of 8.
The next digit of our result is 3. 
Result so far: 23.0
If we subtract 135 from 143, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 45

Moving on to step 5:
45 can be fit into 87 1 times, resulting in a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 231.0
If we subtract 45 from 87, we get 42.
Grab the next digit (2) from the dividend, add it to 42, then carry on: 422 / 45

Advancing to step 6:
45 can be fit into 422 9 times, resulting in a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 2319.0
If we take 405 away from 422, 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:
170 divided by 45 is 3 with a remainder of 35.
Put 3 as the next digit of the answer. 
Result so far: 2319.3
Subtract 135 from 170 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 8:
The number 45 fits into 350 7 times, leaving a remainder of 35.
Record the quotient 7 as the next digit in the result. 
Result so far: 2319.37
The remainder is 35 after subtracting 315 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 9:
45 can be fit into 350 7 times, resulting in a remainder of 35.
The next digit of our result is 7. 
Result so far: 2319.377
Subtracting 315 from 350 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 2319.377 and a remainder of 0.0035.
