Let's divide 621930 by 45
We want to divide 621930 by 45.

Going ahead to step 1:
The number 45 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 45

Advancing to step 2:
If we divide 62 by 45, we get 1 and a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 45 from 62 and we're left with 17.
Fetch the next digit (1) from the dividend, attach it to 17 and continue: 171 / 45

Moving on to step 3:
45 goes into 171 3 times with a remainder of 36.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we subtract 135 from 171, we get 36.
Include the next digit (9) from the dividend after 36, then repeat: 369 / 45

Advancing to step 4:
45 goes into 369 8 times with a remainder of 9.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
Subtract 360 from 369 to get 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 45

Let's proceed to step 5:
The number 45 fits into 93 2 times, leaving a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 1382.0
Deduct 90 from 93 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 45

Moving on to step 6:
45 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 13820.0
Subtract 0 from 30 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.

Step 7:
45 goes into 300 6 times with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 13820.6
Subtracting 270 from 300 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:
When dividing 300 by 45, we get 6 with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 13820.66
Subtracting 270 from 300 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.

After the division, we end up with 13820.66 and a remainder of 0.03.
