We divide 622385 by 90
Our goal is to divide 622385 by 90.

Advancing to step 1:
If we divide 6 by 90, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 90

Advancing to step 2:
When dividing 62 by 90, we get 0 with a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 62 to get 62.
Include the next digit (2) from the dividend after 62, then repeat: 622 / 90

Advancing to step 3:
If we divide 622 by 90, we get 6 and a remainder of 82.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 540 from 622 to get 82.
Bring next digit (3) of the dividend behind the 82 and repeat the process: 823 / 90

Moving on to step 4:
The number 90 fits into 823 9 times, leaving a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
Deduct 810 from 823 and we're left with 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 90

Let's proceed to step 5:
If we divide 138 by 90, we get 1 and a remainder of 48.
Write down 1 as next digit of the result. 
Result so far: 691.0
The remainder is 48 after subtracting 90 from 138.
Fetch the next digit (5) from the dividend, attach it to 48 and continue: 485 / 90

Let's proceed to step 6:
90 can be fit into 485 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 6915.0
Subtracting 450 from 485 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
350 divided by 90 is 3 with a remainder of 80.
The next digit of our result is 3. 
Result so far: 6915.3
Subtracting 270 from 350 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 8:
800 divided by 90 is 8 with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 6915.38
The remainder is 80 after subtracting 720 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 9:
800 divided by 90 is 8 with a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 6915.388
Subtracting 720 from 800 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

After the division, we end up with 6915.388 and a remainder of 0.008.
