99921062 divided by 404 
The aim is to understand the frequency of 404 in 99921062.

Moving on to step 1:
If we divide 9 by 404, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 404

Going ahead 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
Subtract 0 from 99 to get 99.
Append the next digit (9) from the dividend to 99 and continue with: 999 / 404

Moving on to step 3:
If we divide 999 by 404, we get 2 and a remainder of 191.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 808 from 999, we get 191.
Include the next digit (2) from the dividend after 191, then repeat: 1912 / 404

Moving on to step 4:
404 goes into 1912 4 times with a remainder of 296.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we subtract 1616 from 1912, we get 296.
Bring next digit (1) of the dividend behind the 296 and repeat the process: 2961 / 404

Let's proceed to step 5:
If we divide 2961 by 404, we get 7 and a remainder of 133.
Record the quotient 7 as the next digit in the result. 
Result so far: 247.0
If we subtract 2828 from 2961, we get 133.
Grab the next digit (0) from the dividend, add it to 133, then carry on: 1330 / 404

Step 6:
1330 divided by 404 is 3 with a remainder of 118.
The number 3 becomes the next digit in our result. 
Result so far: 2473.0
Subtracting 1212 from 1330 leaves us with 118.
Take the next digit (6) from the dividend and append it to 118, then repeat: 1186 / 404

On to step 7:
The number 404 fits into 1186 2 times, leaving a remainder of 378.
Put 2 as the next digit of the answer. 
Result so far: 24732.0
Subtract 808 from 1186 to get 378.
Take the next digit (2) from the dividend and append it to 378, then repeat: 3782 / 404

Moving on to step 8:
404 goes into 3782 9 times with a remainder of 146.
The number 9 becomes the next digit in our result. 
Result so far: 247329.0
Subtract 3636 from 3782 to get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Advancing to step 9:
1460 divided by 404 is 3 with a remainder of 248.
Use 3 as the next digit of our solution. 
Result so far: 247329.3
Subtracting 1212 from 1460 leaves us with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

On to step 10:
The number 404 fits into 2480 6 times, leaving a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 247329.36
Subtracting 2424 from 2480 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 11:
404 can be fit into 560 1 times, resulting in a remainder of 156.
Use 1 as the next digit of our solution. 
Result so far: 247329.361
Deduct 404 from 560 and we're left with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 12:
When dividing 1560 by 404, we get 3 with a remainder of 348.
Write down 3 as next digit of the result. 
Result so far: 247329.3613
Deduct 1212 from 1560 and we're left with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Let's proceed to step 13:
404 can be fit into 3480 8 times, resulting in a remainder of 248.
Put 8 as the next digit of the answer. 
Result so far: 247329.36138
Subtract 3232 from 3480 to get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 14:
2480 divided by 404 is 6 with a remainder of 56.
Put 6 as the next digit of the answer. 
Result so far: 247329.361386
If we subtract 2424 from 2480, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 15:
404 goes into 560 1 times with a remainder of 156.
The number 1 becomes the next digit in our result. 
Result so far: 247329.3613861
Subtracting 404 from 560 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Going ahead to step 16:
1560 divided by 404 is 3 with a remainder of 348.
Write down 3 as next digit of the result. 
Result so far: 247329.36138613
If we take 1212 away from 1560, we end up with 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

After the division, we end up with 247329.36138613 and a remainder of 3.48e-07.
