993407 divided by 90 
We want to divide 993407 by 90.

Going ahead to step 1:
90 can be fit into 9 0 times, resulting in a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 90

Step 2:
When dividing 99 by 90, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 90 from 99 leaves us with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 90

Going ahead to step 3:
The number 90 fits into 93 1 times, leaving a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 3 after subtracting 90 from 93.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 90

On to step 4:
34 divided by 90 is 0 with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 110.0
The remainder is 34 after subtracting 0 from 34.
Append the next digit (0) from the dividend to 34 and continue with: 340 / 90

Advancing to step 5:
340 divided by 90 is 3 with a remainder of 70.
Record the quotient 3 as the next digit in the result. 
Result so far: 1103.0
If we subtract 270 from 340, we get 70.
Fetch the next digit (7) from the dividend, attach it to 70 and continue: 707 / 90

Going ahead to step 6:
If we divide 707 by 90, we get 7 and a remainder of 77.
Record the quotient 7 as the next digit in the result. 
Result so far: 11037.0
Deduct 630 from 707 and we're left with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 7:
90 goes into 770 8 times with a remainder of 50.
The next digit of our result is 8. 
Result so far: 11037.8
Deduct 720 from 770 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
The number 90 fits into 500 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 11037.85
Deduct 450 from 500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
90 goes into 500 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 11037.855
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The quotient of the division is 11037.855, and the remainder is 0.005.
