939970 divided by 90 
Our goal is to divide 939970 by 90.

On to step 1:
90 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 90

Let's proceed to step 2:
If we divide 93 by 90, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 90 from 93 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 90

Let's proceed to step 3:
90 goes into 39 0 times with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 90

Moving on to step 4:
If we divide 399 by 90, we get 4 and a remainder of 39.
The next digit of our result is 4. 
Result so far: 104.0
Subtracting 360 from 399 leaves us with 39.
Include the next digit (7) from the dividend after 39, then repeat: 397 / 90

Let's proceed to step 5:
90 can be fit into 397 4 times, resulting in a remainder of 37.
The number 4 becomes the next digit in our result. 
Result so far: 1044.0
Subtract 360 from 397 to get 37.
Grab the next digit (0) from the dividend, add it to 37, then carry on: 370 / 90

Let's proceed to step 6:
If we divide 370 by 90, we get 4 and a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 10444.0
If we subtract 360 from 370, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
100 divided by 90 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 10444.1
Deduct 90 from 100 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
The number 90 fits into 100 1 times, leaving a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 10444.11
If we take 90 away from 100, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

The final outcome is 10444.11, with a leftover of 0.01.
