90482191 ÷ 3 
Our goal is to divide 90482191 by 3.

Let's proceed to step 1:
When dividing 9 by 3, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 0 after subtracting 9 from 9.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 3

Advancing to step 2:
If we divide 0 by 3, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Deduct 0 from 0 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 3

On to step 3:
3 can be fit into 4 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 301.0
If we subtract 3 from 4, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 3

On to step 4:
If we divide 18 by 3, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 3016.0
Subtracting 18 from 18 leaves us with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 3

Step 5:
3 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 30160.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 3

Going ahead to step 6:
If we divide 21 by 3, we get 7 and a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 301607.0
If we take 21 away from 21, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 3

Moving on to step 7:
9 divided by 3 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3016073.0
Deduct 9 from 9 and we're left with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 3

Let's proceed to step 8:
3 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 30160730.0
Subtract 0 from 1 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.

Advancing to step 9:
3 goes into 10 3 times with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 30160730.3
Subtracting 9 from 10 leaves us 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.

On to step 10:
10 divided by 3 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 30160730.33
If we take 9 away from 10, 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.

The quotient of the division is 30160730.33, and the remainder is 0.001.
