We're dividing 944343 by 45 
We're looking to find how many times 45 goes into 944343.

Step 1:
When dividing 9 by 45, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 45

Moving on to step 2:
94 divided by 45 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 90 from 94, we get 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 45

On to step 3:
The number 45 fits into 44 0 times, leaving a remainder of 44.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtract 0 from 44 to get 44.
Fetch the next digit (3) from the dividend, attach it to 44 and continue: 443 / 45

Advancing to step 4:
443 divided by 45 is 9 with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 209.0
Deduct 405 from 443 and we're left with 38.
Include the next digit (4) from the dividend after 38, then repeat: 384 / 45

Advancing to step 5:
45 can be fit into 384 8 times, resulting in a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 2098.0
Subtract 360 from 384 to get 24.
Append the next digit (3) from the dividend to 24 and continue with: 243 / 45

Advancing to step 6:
The number 45 fits into 243 5 times, leaving a remainder of 18.
The next digit of our result is 5. 
Result so far: 20985.0
The remainder is 18 after subtracting 225 from 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
180 divided by 45 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 20985.4
If we take 180 away from 180, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
When dividing 0 by 45, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 20985.4
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
If we divide 0 by 45, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20985.4
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 20985.4 with a remainder of 0.0.
