Let's divide 939579 by 90
Let's see how many times 90 fits into 939579.

Going ahead to step 1:
If we divide 9 by 90, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 90

Moving on to step 2:
When dividing 93 by 90, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 90 from 93 and we're left with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 90

On to step 3:
The number 90 fits into 39 0 times, leaving a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 39, we get 39.
Fetch the next digit (5) from the dividend, attach it to 39 and continue: 395 / 90

Advancing to step 4:
If we divide 395 by 90, we get 4 and a remainder of 35.
The next digit of our result is 4. 
Result so far: 104.0
If we take 360 away from 395, we end up with 35.
Bring next digit (7) of the dividend behind the 35 and repeat the process: 357 / 90

Moving on to step 5:
90 can be fit into 357 3 times, resulting in a remainder of 87.
Record the quotient 3 as the next digit in the result. 
Result so far: 1043.0
If we subtract 270 from 357, we get 87.
Grab the next digit (9) from the dividend, add it to 87, then carry on: 879 / 90

Step 6:
90 goes into 879 9 times with a remainder of 69.
Record the quotient 9 as the next digit in the result. 
Result so far: 10439.0
If we take 810 away from 879, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 7:
When dividing 690 by 90, we get 7 with a remainder of 60.
Write down 7 as next digit of the result. 
Result so far: 10439.7
If we subtract 630 from 690, we 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.

Going ahead to step 8:
The number 90 fits into 600 6 times, leaving a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 10439.76
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.

Advancing to step 9:
When dividing 600 by 90, we get 6 with a remainder of 60.
Record the quotient 6 as the next digit in the result. 
Result so far: 10439.766
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 10439.766 and a remainder of 0.006.
