We divide 90493135 by 3
We want to divide 90493135 by 3.

Let's proceed to step 1:
3 can be fit into 9 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 9 from 9, we get 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 3

On to step 2:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
Deduct 0 from 0 and we're left with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 3

On to step 3:
When dividing 4 by 3, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 301.0
Subtracting 3 from 4 leaves us with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 3

Let's proceed to step 4:
3 goes into 19 6 times with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 3016.0
Subtract 18 from 19 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 3

Advancing to step 5:
The number 3 fits into 13 4 times, leaving a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 30164.0
If we subtract 12 from 13, we get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 3

Moving on to step 6:
11 divided by 3 is 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 301643.0
Subtracting 9 from 11 leaves us with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 3

Moving on to step 7:
3 can be fit into 23 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 3016437.0
Subtract 21 from 23 to get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 3

Moving on to step 8:
3 goes into 25 8 times with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 30164378.0
If we take 24 away from 25, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 9:
When dividing 10 by 3, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 30164378.3
Subtract 9 from 10 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 30164378.33
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 30164378.33 and a remainder of 0.001.
