97545562 ÷ 404 
The aim is to understand the frequency of 404 in 97545562.

Step 1:
9 divided by 404 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 404

Going ahead to step 2:
97 divided by 404 is 0 with a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 97, we get 97.
Fetch the next digit (5) from the dividend, attach it to 97 and continue: 975 / 404

Advancing to step 3:
The number 404 fits into 975 2 times, leaving a remainder of 167.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 808 from 975 leaves us with 167.
Fetch the next digit (4) from the dividend, attach it to 167 and continue: 1674 / 404

Going ahead to step 4:
1674 divided by 404 is 4 with a remainder of 58.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtract 1616 from 1674 to get 58.
Bring next digit (5) of the dividend behind the 58 and repeat the process: 585 / 404

On to step 5:
If we divide 585 by 404, we get 1 and a remainder of 181.
The next digit of our result is 1. 
Result so far: 241.0
Deduct 404 from 585 and we're left with 181.
Grab the next digit (5) from the dividend, add it to 181, then carry on: 1815 / 404

Advancing to step 6:
404 goes into 1815 4 times with a remainder of 199.
Record the quotient 4 as the next digit in the result. 
Result so far: 2414.0
Deduct 1616 from 1815 and we're left with 199.
Take the next digit (6) from the dividend and append it to 199, then repeat: 1996 / 404

Step 7:
404 goes into 1996 4 times with a remainder of 380.
The next digit of our result is 4. 
Result so far: 24144.0
Deduct 1616 from 1996 and we're left with 380.
Include the next digit (2) from the dividend after 380, then repeat: 3802 / 404

Moving on to step 8:
When dividing 3802 by 404, we get 9 with a remainder of 166.
Use 9 as the next digit of our solution. 
Result so far: 241449.0
If we subtract 3636 from 3802, we get 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 9:
When dividing 1660 by 404, we get 4 with a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 241449.4
Subtracting 1616 from 1660 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 10:
The number 404 fits into 440 1 times, leaving a remainder of 36.
Put 1 as the next digit of the answer. 
Result so far: 241449.41
Subtract 404 from 440 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
404 can be fit into 360 0 times, resulting in a remainder of 360.
Write down 0 as next digit of the result. 
Result so far: 241449.41
Subtract 0 from 360 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 12:
404 goes into 3600 8 times with a remainder of 368.
The number 8 becomes the next digit in our result. 
Result so far: 241449.4108
If we subtract 3232 from 3600, we get 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Step 13:
When dividing 3680 by 404, we get 9 with a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 241449.41089
If we subtract 3636 from 3680, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 14:
If we divide 440 by 404, we get 1 and a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 241449.410891
Deduct 404 from 440 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 15:
360 divided by 404 is 0 with a remainder of 360.
Use 0 as the next digit of our solution. 
Result so far: 241449.410891
Deduct 0 from 360 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 16:
When dividing 3600 by 404, we get 8 with a remainder of 368.
Put 8 as the next digit of the answer. 
Result so far: 241449.41089108
Subtracting 3232 from 3600 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

After the division, we end up with 241449.41089108 and a remainder of 3.68e-07.
