171218 divided by 45 
We want to figure out the number of times 171218 can be divided by 45.

Let's proceed to step 1:
If we divide 1 by 45, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 45

Step 2:
45 goes into 17 0 times with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 17 and we're left with 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 45

Let's proceed to step 3:
The number 45 fits into 171 3 times, leaving a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 135 from 171 to get 36.
Bring next digit (2) of the dividend behind the 36 and repeat the process: 362 / 45

Let's proceed to step 4:
When dividing 362 by 45, we get 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 38.0
If we subtract 360 from 362, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 45

Advancing to step 5:
When dividing 21 by 45, we get 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 380.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (8) from the dividend, attach it to 21 and continue: 218 / 45

Step 6:
If we divide 218 by 45, we get 4 and a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 3804.0
If we take 180 away from 218, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 7:
When dividing 380 by 45, we get 8 with a remainder of 20.
The next digit of our result is 8. 
Result so far: 3804.8
If we subtract 360 from 380, 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.

On to step 8:
45 can be fit into 200 4 times, resulting in a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 3804.84
The remainder is 20 after subtracting 180 from 200.
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:
When dividing 200 by 45, we get 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 3804.844
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.

In conclusion, the division gives 3804.844 with a balance of 0.002.
