We look at the division of 173365 by 45 
Our goal is to divide 173365 by 45.

Step 1:
45 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 45

Step 2:
45 goes into 17 0 times with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 45

Advancing to step 3:
45 can be fit into 173 3 times, resulting in a remainder of 38.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 135 from 173 leaves us with 38.
Take the next digit (3) from the dividend and append it to 38, then repeat: 383 / 45

Moving on to step 4:
When dividing 383 by 45, we get 8 with a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we take 360 away from 383, we end up with 23.
Take the next digit (6) from the dividend and append it to 23, then repeat: 236 / 45

Advancing to step 5:
If we divide 236 by 45, we get 5 and a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 385.0
If we subtract 225 from 236, we get 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 45

Step 6:
45 can be fit into 115 2 times, resulting in a remainder of 25.
Write down 2 as next digit of the result. 
Result so far: 3852.0
Deduct 90 from 115 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 7:
The number 45 fits into 250 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 3852.5
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 8:
If we divide 250 by 45, we get 5 and a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 3852.55
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

In conclusion, the division gives 3852.55 with a balance of 0.025.
