8286697 ÷ 404 
The aim is to understand the frequency of 404 in 8286697.

Advancing to step 1:
The number 404 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 404

Advancing to step 2:
82 divided by 404 is 0 with a remainder of 82.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 82, we get 82.
Fetch the next digit (8) from the dividend, attach it to 82 and continue: 828 / 404

Going ahead to step 3:
When dividing 828 by 404, we get 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 808 away from 828, we end up with 20.
Bring next digit (6) of the dividend behind the 20 and repeat the process: 206 / 404

Moving on to step 4:
If we divide 206 by 404, we get 0 and a remainder of 206.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtract 0 from 206 to get 206.
Take the next digit (6) from the dividend and append it to 206, then repeat: 2066 / 404

Advancing to step 5:
The number 404 fits into 2066 5 times, leaving a remainder of 46.
Write down 5 as next digit of the result. 
Result so far: 205.0
If we subtract 2020 from 2066, we get 46.
Fetch the next digit (9) from the dividend, attach it to 46 and continue: 469 / 404

Let's proceed to step 6:
404 goes into 469 1 times with a remainder of 65.
Record the quotient 1 as the next digit in the result. 
Result so far: 2051.0
If we take 404 away from 469, we end up with 65.
Take the next digit (7) from the dividend and append it to 65, then repeat: 657 / 404

Advancing to step 7:
404 can be fit into 657 1 times, resulting in a remainder of 253.
Record the quotient 1 as the next digit in the result. 
Result so far: 20511.0
If we take 404 away from 657, we end up with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Let's proceed to step 8:
2530 divided by 404 is 6 with a remainder of 106.
Put 6 as the next digit of the answer. 
Result so far: 20511.6
If we take 2424 away from 2530, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

On to step 9:
404 can be fit into 1060 2 times, resulting in a remainder of 252.
Record the quotient 2 as the next digit in the result. 
Result so far: 20511.62
Subtracting 808 from 1060 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Going ahead to step 10:
404 goes into 2520 6 times with a remainder of 96.
The next digit of our result is 6. 
Result so far: 20511.626
Deduct 2424 from 2520 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 11:
If we divide 960 by 404, we get 2 and a remainder of 152.
The next digit of our result is 2. 
Result so far: 20511.6262
Subtracting 808 from 960 leaves us with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 12:
When dividing 1520 by 404, we get 3 with a remainder of 308.
Use 3 as the next digit of our solution. 
Result so far: 20511.62623
The remainder is 308 after subtracting 1212 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Going ahead to step 13:
3080 divided by 404 is 7 with a remainder of 252.
The next digit of our result is 7. 
Result so far: 20511.626237
The remainder is 252 after subtracting 2828 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 14:
The number 404 fits into 2520 6 times, leaving a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 20511.6262376
If we take 2424 away from 2520, we end up with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 15:
404 goes into 960 2 times with a remainder of 152.
The next digit of our result is 2. 
Result so far: 20511.62623762
The remainder is 152 after subtracting 808 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

The final result is 20511.62623762 with a remainder of 1.52e-07.
