We divide 621200 by 45
Our goal is to divide 621200 by 45.

Let's proceed to step 1:
45 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 45

Going ahead to step 2:
45 goes into 62 1 times with a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 45 from 62, we get 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 45

Let's proceed to step 3:
171 divided by 45 is 3 with a remainder of 36.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 135 away from 171, we end up with 36.
Grab the next digit (2) from the dividend, add it to 36, then carry on: 362 / 45

Advancing 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: 138.0
Subtract 360 from 362 to get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 45

Let's proceed to step 5:
20 divided by 45 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1380.0
The remainder is 20 after subtracting 0 from 20.
Include the next digit (0) from the dividend after 20, then repeat: 200 / 45

Moving on to step 6:
When dividing 200 by 45, we get 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 13804.0
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.

Let's proceed to step 7:
The number 45 fits into 200 4 times, leaving a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 13804.4
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.

Going ahead to step 8:
45 goes into 200 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 13804.44
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.

The quotient of the division is 13804.44, and the remainder is 0.02.
