422112 divided by 45 
Let's see how many times 45 fits into 422112.

Going ahead to step 1:
The number 45 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 45

On to step 2:
45 goes into 42 0 times with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Take the next digit (2) from the dividend and append it to 42, then repeat: 422 / 45

On to step 3:
The number 45 fits into 422 9 times, leaving a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 405 from 422, we get 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 45

Let's proceed to step 4:
When dividing 171 by 45, we get 3 with a remainder of 36.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
If we subtract 135 from 171, we get 36.
Fetch the next digit (1) from the dividend, attach it to 36 and continue: 361 / 45

Step 5:
If we divide 361 by 45, we get 8 and a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 938.0
Deduct 360 from 361 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 45

Moving on to step 6:
45 can be fit into 12 0 times, resulting in a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 9380.0
Subtract 0 from 12 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
120 divided by 45 is 2 with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 9380.2
Subtracting 90 from 120 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
45 can be fit into 300 6 times, resulting in a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 9380.26
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
45 goes into 300 6 times with a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 9380.266
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 9380.266 with a remainder of 0.003.
