We look at the division of 333972 by 45 
Let's see how many times 45 fits into 333972.

Step 1:
45 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 45

Step 2:
33 divided by 45 is 0 with a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 33 after subtracting 0 from 33.
Grab the next digit (3) from the dividend, add it to 33, then carry on: 333 / 45

Going ahead to step 3:
45 goes into 333 7 times with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 315 from 333, we get 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 45

Step 4:
If we divide 189 by 45, we get 4 and a remainder of 9.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
Deduct 180 from 189 and we're left with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 45

Moving on to step 5:
If we divide 97 by 45, we get 2 and a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 742.0
The remainder is 7 after subtracting 90 from 97.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 45

Let's proceed to step 6:
When dividing 72 by 45, we get 1 with a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 7421.0
The remainder is 27 after subtracting 45 from 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 7:
The number 45 fits into 270 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 7421.6
Subtracting 270 from 270 leaves us 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:
The number 45 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7421.6
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.

Going ahead to step 9:
If we divide 0 by 45, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7421.6
If we take 0 away from 0, 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.

The final result is 7421.6 with a remainder of 0.0.
