1163323 ÷ 404 
The aim is to understand the frequency of 404 in 1163323.

Advancing to step 1:
If we divide 1 by 404, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 404

On to step 2:
The number 404 fits into 11 0 times, leaving a remainder of 11.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 404

Going ahead to step 3:
If we divide 116 by 404, we get 0 and a remainder of 116.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 116 after subtracting 0 from 116.
Fetch the next digit (3) from the dividend, attach it to 116 and continue: 1163 / 404

Going ahead to step 4:
When dividing 1163 by 404, we get 2 with a remainder of 355.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 355 after subtracting 808 from 1163.
Take the next digit (3) from the dividend and append it to 355, then repeat: 3553 / 404

Let's proceed to step 5:
The number 404 fits into 3553 8 times, leaving a remainder of 321.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we take 3232 away from 3553, we end up with 321.
Take the next digit (2) from the dividend and append it to 321, then repeat: 3212 / 404

Advancing to step 6:
404 goes into 3212 7 times with a remainder of 384.
Record the quotient 7 as the next digit in the result. 
Result so far: 287.0
The remainder is 384 after subtracting 2828 from 3212.
Bring next digit (3) of the dividend behind the 384 and repeat the process: 3843 / 404

On to step 7:
If we divide 3843 by 404, we get 9 and a remainder of 207.
Put 9 as the next digit of the answer. 
Result so far: 2879.0
Deduct 3636 from 3843 and we're left with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Let's proceed to step 8:
When dividing 2070 by 404, we get 5 with a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 2879.5
If we take 2020 away from 2070, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 9:
500 divided by 404 is 1 with a remainder of 96.
Use 1 as the next digit of our solution. 
Result so far: 2879.51
If we subtract 404 from 500, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Moving on to step 10:
404 can be fit into 960 2 times, resulting in a remainder of 152.
The number 2 becomes the next digit in our result. 
Result so far: 2879.512
If we take 808 away from 960, we end up 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.

Moving on to step 11:
404 goes into 1520 3 times with a remainder of 308.
Put 3 as the next digit of the answer. 
Result so far: 2879.5123
If we subtract 1212 from 1520, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 12:
The number 404 fits into 3080 7 times, leaving a remainder of 252.
The next digit of our result is 7. 
Result so far: 2879.51237
If we subtract 2828 from 3080, we get 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 13:
The number 404 fits into 2520 6 times, leaving a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 2879.512376
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.

Step 14:
The number 404 fits into 960 2 times, leaving a remainder of 152.
The number 2 becomes the next digit in our result. 
Result so far: 2879.5123762
Subtract 808 from 960 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 15:
1520 divided by 404 is 3 with a remainder of 308.
Write down 3 as next digit of the result. 
Result so far: 2879.51237623
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.

The final outcome is 2879.51237623, with a leftover of 3.08e-07.
