Let's divide 766644 by 90
We want to divide 766644 by 90.

Let's proceed to step 1:
90 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 90

Step 2:
90 can be fit into 76 0 times, resulting in a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Bring next digit (6) of the dividend behind the 76 and repeat the process: 766 / 90

Moving on to step 3:
766 divided by 90 is 8 with a remainder of 46.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 720 from 766 and we're left with 46.
Bring next digit (6) of the dividend behind the 46 and repeat the process: 466 / 90

On to step 4:
90 can be fit into 466 5 times, resulting in a remainder of 16.
The next digit of our result is 5. 
Result so far: 85.0
If we subtract 450 from 466, we get 16.
Fetch the next digit (4) from the dividend, attach it to 16 and continue: 164 / 90

Let's proceed to step 5:
When dividing 164 by 90, we get 1 with a remainder of 74.
Write down 1 as next digit of the result. 
Result so far: 851.0
The remainder is 74 after subtracting 90 from 164.
Append the next digit (4) from the dividend to 74 and continue with: 744 / 90

Going ahead to step 6:
If we divide 744 by 90, we get 8 and a remainder of 24.
The number 8 becomes the next digit in our result. 
Result so far: 8518.0
If we subtract 720 from 744, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 7:
90 goes into 240 2 times with a remainder of 60.
Record the quotient 2 as the next digit in the result. 
Result so far: 8518.2
The remainder is 60 after subtracting 180 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 8:
90 can be fit into 600 6 times, resulting in a remainder of 60.
The number 6 becomes the next digit in our result. 
Result so far: 8518.26
Subtract 540 from 600 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 9:
600 divided by 90 is 6 with a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 8518.266
If we take 540 away from 600, 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.

The final outcome is 8518.266, with a leftover of 0.006.
