620824 ÷ 45 
We want to divide 620824 by 45.

Going ahead to step 1:
45 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 45

On to step 2:
45 can be fit into 62 1 times, resulting in 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 (0) from the dividend, add it to 17, then carry on: 170 / 45

Let's proceed to step 3:
45 goes into 170 3 times with a remainder of 35.
The next digit of our result is 3. 
Result so far: 13.0
If we take 135 away from 170, we end up with 35.
Grab the next digit (8) from the dividend, add it to 35, then carry on: 358 / 45

Moving on to step 4:
If we divide 358 by 45, we get 7 and a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 137.0
Subtract 315 from 358 to get 43.
Fetch the next digit (2) from the dividend, attach it to 43 and continue: 432 / 45

Moving on to step 5:
432 divided by 45 is 9 with a remainder of 27.
The number 9 becomes the next digit in our result. 
Result so far: 1379.0
Subtract 405 from 432 to get 27.
Append the next digit (4) from the dividend to 27 and continue with: 274 / 45

Let's proceed to step 6:
The number 45 fits into 274 6 times, leaving a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 13796.0
Subtract 270 from 274 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
40 divided by 45 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 13796.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
If we divide 400 by 45, we get 8 and a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 13796.08
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
400 divided by 45 is 8 with a remainder of 40.
Put 8 as the next digit of the answer. 
Result so far: 13796.088
Deduct 360 from 400 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 13796.088, with a leftover of 0.004.
