Let's divide 9911929 by 404
Let's see how many times 404 fits into 9911929.

Step 1:
The number 404 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 404

Moving on to step 2:
99 divided by 404 is 0 with a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Append the next digit (1) from the dividend to 99 and continue with: 991 / 404

On to step 3:
404 can be fit into 991 2 times, resulting in a remainder of 183.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 808 from 991 to get 183.
Include the next digit (1) from the dividend after 183, then repeat: 1831 / 404

Going ahead to step 4:
404 can be fit into 1831 4 times, resulting in a remainder of 215.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we take 1616 away from 1831, we end up with 215.
Fetch the next digit (9) from the dividend, attach it to 215 and continue: 2159 / 404

On to step 5:
The number 404 fits into 2159 5 times, leaving a remainder of 139.
Write down 5 as next digit of the result. 
Result so far: 245.0
Deduct 2020 from 2159 and we're left with 139.
Append the next digit (2) from the dividend to 139 and continue with: 1392 / 404

Advancing to step 6:
The number 404 fits into 1392 3 times, leaving a remainder of 180.
Put 3 as the next digit of the answer. 
Result so far: 2453.0
If we take 1212 away from 1392, we end up with 180.
Bring next digit (9) of the dividend behind the 180 and repeat the process: 1809 / 404

On to step 7:
When dividing 1809 by 404, we get 4 with a remainder of 193.
The number 4 becomes the next digit in our result. 
Result so far: 24534.0
Subtract 1616 from 1809 to get 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Step 8:
If we divide 1930 by 404, we get 4 and a remainder of 314.
Put 4 as the next digit of the answer. 
Result so far: 24534.4
The remainder is 314 after subtracting 1616 from 1930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

Step 9:
3140 divided by 404 is 7 with a remainder of 312.
Use 7 as the next digit of our solution. 
Result so far: 24534.47
Subtract 2828 from 3140 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Advancing to step 10:
The number 404 fits into 3120 7 times, leaving a remainder of 292.
Write down 7 as next digit of the result. 
Result so far: 24534.477
Subtracting 2828 from 3120 leaves us with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

The final outcome is 24534.477, with a leftover of 0.0292.
