We divide 620205 by 90
We want to figure out the number of times 620205 can be divided by 90.

Let's proceed to step 1:
6 divided by 90 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 90

Advancing to step 2:
If we divide 62 by 90, we get 0 and a remainder of 62.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 62 leaves us with 62.
Take the next digit (0) from the dividend and append it to 62, then repeat: 620 / 90

Step 3:
90 can be fit into 620 6 times, resulting in a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 540 from 620 to get 80.
Include the next digit (2) from the dividend after 80, then repeat: 802 / 90

Advancing to step 4:
802 divided by 90 is 8 with a remainder of 82.
Use 8 as the next digit of our solution. 
Result so far: 68.0
Subtracting 720 from 802 leaves us with 82.
Bring next digit (0) of the dividend behind the 82 and repeat the process: 820 / 90

Advancing to step 5:
90 goes into 820 9 times with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 689.0
If we subtract 810 from 820, we get 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 90

Let's proceed to step 6:
If we divide 105 by 90, we get 1 and a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 6891.0
If we subtract 90 from 105, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
The number 90 fits into 150 1 times, leaving a remainder of 60.
Write down 1 as next digit of the result. 
Result so far: 6891.1
If we take 90 away from 150, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
600 divided by 90 is 6 with a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 6891.16
Deduct 540 from 600 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
90 goes into 600 6 times with a remainder of 60.
Use 6 as the next digit of our solution. 
Result so far: 6891.166
Subtracting 540 from 600 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 6891.166 and a remainder of 0.006.
