Let's divide 620666 by 90
Let's see how many times 90 fits into 620666.

On to step 1:
90 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 90

On to step 2:
When dividing 62 by 90, we get 0 with a remainder of 62.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 62 after subtracting 0 from 62.
Grab the next digit (0) from the dividend, add it to 62, then carry on: 620 / 90

Let's proceed to step 3:
If we divide 620 by 90, we get 6 and a remainder of 80.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we subtract 540 from 620, we get 80.
Grab the next digit (6) from the dividend, add it to 80, then carry on: 806 / 90

Let's proceed to step 4:
806 divided by 90 is 8 with a remainder of 86.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
If we take 720 away from 806, we end up with 86.
Include the next digit (6) from the dividend after 86, then repeat: 866 / 90

Going ahead to step 5:
90 can be fit into 866 9 times, resulting in a remainder of 56.
Use 9 as the next digit of our solution. 
Result so far: 689.0
Subtracting 810 from 866 leaves us with 56.
Include the next digit (6) from the dividend after 56, then repeat: 566 / 90

Moving on to step 6:
90 can be fit into 566 6 times, resulting in a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 6896.0
Subtract 540 from 566 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 7:
When dividing 260 by 90, we get 2 with a remainder of 80.
Use 2 as the next digit of our solution. 
Result so far: 6896.2
If we subtract 180 from 260, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 8:
If we divide 800 by 90, we get 8 and a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 6896.28
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.

On to step 9:
90 can be fit into 800 8 times, resulting in a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 6896.288
If we take 720 away from 800, we end up 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.

In conclusion, the division gives 6896.288 with a balance of 0.008.
