172867 divided by 45 
We want to figure out the number of times 172867 can be divided by 45.

Advancing to step 1:
When dividing 1 by 45, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 45

Step 2:
If we divide 17 by 45, we get 0 and a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 45

Moving on to step 3:
45 can be fit into 172 3 times, resulting in a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 37 after subtracting 135 from 172.
Bring next digit (8) of the dividend behind the 37 and repeat the process: 378 / 45

Going ahead to step 4:
The number 45 fits into 378 8 times, leaving a remainder of 18.
The next digit of our result is 8. 
Result so far: 38.0
If we subtract 360 from 378, we get 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 45

Advancing to step 5:
When dividing 186 by 45, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 384.0
If we subtract 180 from 186, we get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 45

On to step 6:
If we divide 67 by 45, we get 1 and a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 3841.0
If we take 45 away from 67, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 7:
If we divide 220 by 45, we get 4 and a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 3841.4
If we take 180 away from 220, 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 8:
45 goes into 400 8 times with a remainder of 40.
Record the quotient 8 as the next digit in the result. 
Result so far: 3841.48
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.

Moving on to step 9:
45 goes into 400 8 times with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 3841.488
If we subtract 360 from 400, we 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.

The quotient of the division is 3841.488, and the remainder is 0.004.
