We divide 622789 by 45
We want to divide 622789 by 45.

Going ahead to step 1:
45 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 45

On to step 2:
If we divide 62 by 45, we get 1 and a remainder of 17.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 45 from 62 leaves us with 17.
Append the next digit (2) from the dividend to 17 and continue with: 172 / 45

Going ahead to step 3:
45 goes into 172 3 times with a remainder of 37.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 135 from 172 leaves us with 37.
Bring next digit (7) of the dividend behind the 37 and repeat the process: 377 / 45

Moving on to step 4:
The number 45 fits into 377 8 times, leaving a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
The remainder is 17 after subtracting 360 from 377.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 45

Going ahead to step 5:
45 goes into 178 3 times with a remainder of 43.
The next digit of our result is 3. 
Result so far: 1383.0
If we take 135 away from 178, we end up with 43.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 45

Let's proceed to step 6:
If we divide 439 by 45, we get 9 and a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 13839.0
If we take 405 away from 439, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
45 goes into 340 7 times with a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 13839.7
The remainder is 25 after subtracting 315 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 8:
If we divide 250 by 45, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 13839.75
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
If we divide 250 by 45, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 13839.755
Subtracting 225 from 250 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 13839.755, and the remainder is 0.0025.
