90499481 divided by 3 
Let's see how many times 3 fits into 90499481.

On to step 1:
If we divide 9 by 3, we get 3 and a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 9 from 9 and we're left with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 3

Going ahead to step 2:
When dividing 0 by 3, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
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

Going ahead to step 3:
If we divide 4 by 3, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 301.0
The remainder is 1 after subtracting 3 from 4.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 3

Going ahead 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
Deduct 18 from 19 and we're left with 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 3

Going ahead to step 5:
If we divide 19 by 3, we get 6 and a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 30166.0
Subtract 18 from 19 to get 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 3

On to step 6:
14 divided by 3 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 301664.0
Subtract 12 from 14 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 3

Moving on to step 7:
When dividing 28 by 3, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 3016649.0
Deduct 27 from 28 and we're left with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 3

Going ahead to step 8:
3 can be fit into 11 3 times, resulting in a remainder of 2.
The next digit of our result is 3. 
Result so far: 30166493.0
If we subtract 9 from 11, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
If we divide 20 by 3, we get 6 and a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 30166493.6
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
3 goes into 20 6 times with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 30166493.66
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 30166493.66, with a leftover of 0.002.
