621335 divided by 45 
Our goal is to divide 621335 by 45.

Let's proceed to step 1:
45 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 45

Moving on to step 2:
The number 45 fits into 62 1 times, leaving a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 45 from 62 and we're left with 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 45

Advancing to step 3:
171 divided by 45 is 3 with a remainder of 36.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 135 from 171 to get 36.
Fetch the next digit (3) from the dividend, attach it to 36 and continue: 363 / 45

Let's proceed to step 4:
45 goes into 363 8 times with a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 138.0
If we take 360 away from 363, we end up with 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 45

Going ahead to step 5:
If we divide 33 by 45, we get 0 and a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 1380.0
The remainder is 33 after subtracting 0 from 33.
Include the next digit (5) from the dividend after 33, then repeat: 335 / 45

Moving on to step 6:
45 can be fit into 335 7 times, resulting in a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 13807.0
Subtract 315 from 335 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.

Step 7:
If we divide 200 by 45, we get 4 and a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 13807.4
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.

On to step 8:
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: 13807.44
Subtract 180 from 200 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.

After the division, we end up with 13807.44 and a remainder of 0.02.
