We're dividing 90197909 by 3 
Let's see how many times 3 fits into 90197909.

Going ahead to step 1:
3 can be fit into 9 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 9 from 9 leaves us with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 3

Step 2:
If we divide 0 by 3, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we take 0 away from 0, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 3

Moving on to step 3:
The number 3 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 300.0
Subtract 0 from 1 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 3

Moving on to step 4:
If we divide 19 by 3, we get 6 and a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 3006.0
Subtracting 18 from 19 leaves us with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 3

Step 5:
If we divide 17 by 3, we get 5 and a remainder of 2.
The next digit of our result is 5. 
Result so far: 30065.0
The remainder is 2 after subtracting 15 from 17.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 3

Step 6:
If we divide 29 by 3, we get 9 and a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 300659.0
If we take 27 away from 29, we end up with 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 3

Step 7:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 3006596.0
Subtracting 18 from 20 leaves us with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 3

Advancing to step 8:
The number 3 fits into 29 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 30065969.0
Subtract 27 from 29 to 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.

On to step 9:
When dividing 20 by 3, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 30065969.6
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 30065969.66
If we take 18 away from 20, we end up with 2.
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 result is 30065969.66 with a remainder of 0.002.
