We're dividing 620255 by 45 
We're looking to find how many times 45 goes into 620255.

Going ahead 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
The remainder is 6 after subtracting 0 from 6.
Append the next digit (2) from the dividend to 6 and continue with: 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
Subtracting 45 from 62 leaves us with 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 45

On to step 3:
When dividing 170 by 45, we get 3 with a remainder of 35.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 135 from 170 leaves us with 35.
Include the next digit (2) from the dividend after 35, then repeat: 352 / 45

Advancing to step 4:
45 goes into 352 7 times with a remainder of 37.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
Deduct 315 from 352 and we're left with 37.
Grab the next digit (5) from the dividend, add it to 37, then carry on: 375 / 45

On to step 5:
45 goes into 375 8 times with a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 1378.0
If we subtract 360 from 375, we get 15.
Include the next digit (5) from the dividend after 15, then repeat: 155 / 45

Advancing to step 6:
The number 45 fits into 155 3 times, leaving a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 13783.0
Subtract 135 from 155 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.

Going ahead to step 7:
The number 45 fits into 200 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 13783.4
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.

Advancing to step 8:
45 goes into 200 4 times with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 13783.44
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.

In conclusion, the division gives 13783.44 with a balance of 0.02.
