172469 divided by 45 
We want to figure out the number of times 172469 can be divided by 45.

Going ahead to step 1:
1 divided by 45 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 45

Going ahead to step 2:
The number 45 fits into 17 0 times, leaving a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 45

Advancing to step 3:
If we divide 172 by 45, we get 3 and a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 135 from 172 to get 37.
Take the next digit (4) from the dividend and append it to 37, then repeat: 374 / 45

Going ahead to step 4:
45 can be fit into 374 8 times, resulting in a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtract 360 from 374 to get 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 45

Let's proceed to step 5:
45 goes into 146 3 times with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 383.0
The remainder is 11 after subtracting 135 from 146.
Fetch the next digit (9) from the dividend, attach it to 11 and continue: 119 / 45

On to step 6:
45 goes into 119 2 times with a remainder of 29.
Record the quotient 2 as the next digit in the result. 
Result so far: 3832.0
Subtracting 90 from 119 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
45 can be fit into 290 6 times, resulting in a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 3832.6
If we take 270 away from 290, we end up with 20.
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:
200 divided by 45 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 3832.64
Deduct 180 from 200 and we're left with 20.
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 9:
The number 45 fits into 200 4 times, leaving a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 3832.644
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 3832.644 with a remaining 0.002.
