We look at the division of 72020 by 45 
Our goal is to divide 72020 by 45.

Moving on to step 1:
When dividing 7 by 45, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 45

Let's proceed to step 2:
45 can be fit into 72 1 times, resulting in a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 45 away from 72, we end up with 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 45

On to step 3:
The number 45 fits into 270 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Subtract 270 from 270 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 45

Let's proceed to step 4:
45 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 160.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 45

Moving on to step 5:
When dividing 20 by 45, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 1600.0
Subtract 0 from 20 to 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 6:
When dividing 200 by 45, we get 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 1600.4
If we take 180 away from 200, 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.

On to step 7:
If we divide 200 by 45, we get 4 and a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 1600.44
Subtracting 180 from 200 leaves us 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.

The final result is 1600.44 with a remainder of 0.02.
