Let's divide 15954777 by 404
The aim is to understand the frequency of 404 in 15954777.

Going ahead to step 1:
If we divide 1 by 404, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 404

Moving on to step 2:
404 goes into 15 0 times with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 404

Moving on to step 3:
159 divided by 404 is 0 with a remainder of 159.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 159 to get 159.
Bring next digit (5) of the dividend behind the 159 and repeat the process: 1595 / 404

Step 4:
The number 404 fits into 1595 3 times, leaving a remainder of 383.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 1212 from 1595, we get 383.
Bring next digit (4) of the dividend behind the 383 and repeat the process: 3834 / 404

On to step 5:
If we divide 3834 by 404, we get 9 and a remainder of 198.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we take 3636 away from 3834, we end up with 198.
Take the next digit (7) from the dividend and append it to 198, then repeat: 1987 / 404

Going ahead to step 6:
404 can be fit into 1987 4 times, resulting in a remainder of 371.
Put 4 as the next digit of the answer. 
Result so far: 394.0
Subtract 1616 from 1987 to get 371.
Grab the next digit (7) from the dividend, add it to 371, then carry on: 3717 / 404

On to step 7:
The number 404 fits into 3717 9 times, leaving a remainder of 81.
Put 9 as the next digit of the answer. 
Result so far: 3949.0
If we subtract 3636 from 3717, we get 81.
Fetch the next digit (7) from the dividend, attach it to 81 and continue: 817 / 404

Advancing to step 8:
404 goes into 817 2 times with a remainder of 9.
Write down 2 as next digit of the result. 
Result so far: 39492.0
Subtracting 808 from 817 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
When dividing 90 by 404, we get 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 39492.0
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 10:
404 can be fit into 900 2 times, resulting in a remainder of 92.
The next digit of our result is 2. 
Result so far: 39492.02
Deduct 808 from 900 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Advancing to step 11:
404 can be fit into 920 2 times, resulting in a remainder of 112.
Record the quotient 2 as the next digit in the result. 
Result so far: 39492.022
Subtract 808 from 920 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

In conclusion, the division gives 39492.022 with a balance of 0.0112.
