We look at the division of 170547 by 45 
We're looking to find how many times 45 goes into 170547.

Moving on to step 1:
45 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 45

On to step 2:
17 divided by 45 is 0 with a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 45

Going ahead to step 3:
The number 45 fits into 170 3 times, leaving a remainder of 35.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 135 from 170 to get 35.
Include the next digit (5) from the dividend after 35, then repeat: 355 / 45

Advancing to step 4:
45 goes into 355 7 times with a remainder of 40.
Use 7 as the next digit of our solution. 
Result so far: 37.0
If we take 315 away from 355, we end up with 40.
Grab the next digit (4) from the dividend, add it to 40, then carry on: 404 / 45

Going ahead to step 5:
45 goes into 404 8 times with a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 378.0
Subtracting 360 from 404 leaves us with 44.
Fetch the next digit (7) from the dividend, attach it to 44 and continue: 447 / 45

Advancing to step 6:
45 goes into 447 9 times with a remainder of 42.
Put 9 as the next digit of the answer. 
Result so far: 3789.0
Subtract 405 from 447 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 7:
The number 45 fits into 420 9 times, leaving a remainder of 15.
The next digit of our result is 9. 
Result so far: 3789.9
If we take 405 away from 420, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 8:
45 can be fit into 150 3 times, resulting in a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 3789.93
If we take 135 away from 150, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
45 goes into 150 3 times with a remainder of 15.
The next digit of our result is 3. 
Result so far: 3789.933
If we take 135 away from 150, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 3789.933 with a balance of 0.0015.
