We look at the division of 99891289 by 404 
We want to divide 99891289 by 404.

On to step 1:
The number 404 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 404

On to step 2:
When dividing 99 by 404, we get 0 with a remainder of 99.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Take the next digit (8) from the dividend and append it to 99, then repeat: 998 / 404

Going ahead to step 3:
If we divide 998 by 404, we get 2 and a remainder of 190.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 808 from 998 and we're left with 190.
Append the next digit (9) from the dividend to 190 and continue with: 1909 / 404

Advancing to step 4:
If we divide 1909 by 404, we get 4 and a remainder of 293.
Put 4 as the next digit of the answer. 
Result so far: 24.0
The remainder is 293 after subtracting 1616 from 1909.
Bring next digit (1) of the dividend behind the 293 and repeat the process: 2931 / 404

Step 5:
2931 divided by 404 is 7 with a remainder of 103.
The number 7 becomes the next digit in our result. 
Result so far: 247.0
If we take 2828 away from 2931, we end up with 103.
Include the next digit (2) from the dividend after 103, then repeat: 1032 / 404

Moving on to step 6:
The number 404 fits into 1032 2 times, leaving a remainder of 224.
Record the quotient 2 as the next digit in the result. 
Result so far: 2472.0
Deduct 808 from 1032 and we're left with 224.
Grab the next digit (8) from the dividend, add it to 224, then carry on: 2248 / 404

Moving on to step 7:
When dividing 2248 by 404, we get 5 with a remainder of 228.
The next digit of our result is 5. 
Result so far: 24725.0
If we take 2020 away from 2248, we end up with 228.
Append the next digit (9) from the dividend to 228 and continue with: 2289 / 404

Let's proceed to step 8:
404 goes into 2289 5 times with a remainder of 269.
Use 5 as the next digit of our solution. 
Result so far: 247255.0
Deduct 2020 from 2289 and we're left with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

On to step 9:
2690 divided by 404 is 6 with a remainder of 266.
The next digit of our result is 6. 
Result so far: 247255.6
Subtract 2424 from 2690 to get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 10:
The number 404 fits into 2660 6 times, leaving a remainder of 236.
Put 6 as the next digit of the answer. 
Result so far: 247255.66
The remainder is 236 after subtracting 2424 from 2660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Our division results in 247255.66 with a remaining 0.236.
