17113052 ÷ 404 
The aim is to understand the frequency of 404 in 17113052.

Step 1:
If we divide 1 by 404, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 404

Step 2:
If we divide 17 by 404, we get 0 and a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Grab the next digit (1) from the dividend, add it to 17, then carry on: 171 / 404

Going ahead to step 3:
If we divide 171 by 404, we get 0 and a remainder of 171.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 171, we end up with 171.
Fetch the next digit (1) from the dividend, attach it to 171 and continue: 1711 / 404

Moving on to step 4:
The number 404 fits into 1711 4 times, leaving a remainder of 95.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 1616 away from 1711, we end up with 95.
Grab the next digit (3) from the dividend, add it to 95, then carry on: 953 / 404

Step 5:
404 can be fit into 953 2 times, resulting in a remainder of 145.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Deduct 808 from 953 and we're left with 145.
Fetch the next digit (0) from the dividend, attach it to 145 and continue: 1450 / 404

Advancing to step 6:
404 goes into 1450 3 times with a remainder of 238.
The number 3 becomes the next digit in our result. 
Result so far: 423.0
Deduct 1212 from 1450 and we're left with 238.
Append the next digit (5) from the dividend to 238 and continue with: 2385 / 404

Advancing to step 7:
404 goes into 2385 5 times with a remainder of 365.
The number 5 becomes the next digit in our result. 
Result so far: 4235.0
If we take 2020 away from 2385, we end up with 365.
Fetch the next digit (2) from the dividend, attach it to 365 and continue: 3652 / 404

Advancing to step 8:
404 goes into 3652 9 times with a remainder of 16.
Put 9 as the next digit of the answer. 
Result so far: 42359.0
If we take 3636 away from 3652, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 9:
404 goes into 160 0 times with a remainder of 160.
The next digit of our result is 0. 
Result so far: 42359.0
If we take 0 away from 160, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 10:
1600 divided by 404 is 3 with a remainder of 388.
Use 3 as the next digit of our solution. 
Result so far: 42359.03
If we subtract 1212 from 1600, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 11:
3880 divided by 404 is 9 with a remainder of 244.
Write down 9 as next digit of the result. 
Result so far: 42359.039
If we subtract 3636 from 3880, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

On to step 12:
404 can be fit into 2440 6 times, resulting in a remainder of 16.
The next digit of our result is 6. 
Result so far: 42359.0396
Subtract 2424 from 2440 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 13:
The number 404 fits into 160 0 times, leaving a remainder of 160.
The next digit of our result is 0. 
Result so far: 42359.0396
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 14:
When dividing 1600 by 404, we get 3 with a remainder of 388.
The number 3 becomes the next digit in our result. 
Result so far: 42359.039603
Subtracting 1212 from 1600 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Step 15:
3880 divided by 404 is 9 with a remainder of 244.
The number 9 becomes the next digit in our result. 
Result so far: 42359.0396039
If we subtract 3636 from 3880, we get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Let's proceed to step 16:
404 goes into 2440 6 times with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 42359.03960396
If we subtract 2424 from 2440, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 42359.03960396 and a remainder of 1.6e-08.
