We divide 9906 by 39
We want to divide 9906 by 39.

Step 1:
39 goes into 9 0 times with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 39

Let's proceed to step 2:
When dividing 99 by 39, we get 2 with a remainder of 21.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 78 from 99 to get 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 39

On to step 3:
The number 39 fits into 210 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 25.0
The remainder is 15 after subtracting 195 from 210.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 39

Advancing to step 4:
The number 39 fits into 156 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 254.0
Subtracting 156 from 156 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 5:
39 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 254.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 6:
The number 39 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 254.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 254.0, and the remainder is 0.0.
