31529854 ÷ 404 
The aim is to understand the frequency of 404 in 31529854.

Let's proceed to step 1:
404 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 404

Step 2:
The number 404 fits into 31 0 times, leaving a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Take the next digit (5) from the dividend and append it to 31, then repeat: 315 / 404

Let's proceed to step 3:
404 goes into 315 0 times with a remainder of 315.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 315, we get 315.
Fetch the next digit (2) from the dividend, attach it to 315 and continue: 3152 / 404

Going ahead to step 4:
If we divide 3152 by 404, we get 7 and a remainder of 324.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we take 2828 away from 3152, we end up with 324.
Include the next digit (9) from the dividend after 324, then repeat: 3249 / 404

On to step 5:
404 can be fit into 3249 8 times, resulting in a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Subtract 3232 from 3249 to get 17.
Bring next digit (8) of the dividend behind the 17 and repeat the process: 178 / 404

Advancing to step 6:
When dividing 178 by 404, we get 0 with a remainder of 178.
Use 0 as the next digit of our solution. 
Result so far: 780.0
Deduct 0 from 178 and we're left with 178.
Bring next digit (5) of the dividend behind the 178 and repeat the process: 1785 / 404

Going ahead to step 7:
404 can be fit into 1785 4 times, resulting in a remainder of 169.
Put 4 as the next digit of the answer. 
Result so far: 7804.0
Subtract 1616 from 1785 to get 169.
Fetch the next digit (4) from the dividend, attach it to 169 and continue: 1694 / 404

Advancing to step 8:
404 goes into 1694 4 times with a remainder of 78.
Use 4 as the next digit of our solution. 
Result so far: 78044.0
Subtracting 1616 from 1694 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 9:
404 can be fit into 780 1 times, resulting in a remainder of 376.
The next digit of our result is 1. 
Result so far: 78044.1
Deduct 404 from 780 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 10:
If we divide 3760 by 404, we get 9 and a remainder of 124.
Record the quotient 9 as the next digit in the result. 
Result so far: 78044.19
Subtract 3636 from 3760 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Moving on to step 11:
When dividing 1240 by 404, we get 3 with a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 78044.193
Subtracting 1212 from 1240 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 12:
404 can be fit into 280 0 times, resulting in a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 78044.193
The remainder is 280 after subtracting 0 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 13:
If we divide 2800 by 404, we get 6 and a remainder of 376.
The number 6 becomes the next digit in our result. 
Result so far: 78044.19306
If we subtract 2424 from 2800, we get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 14:
404 can be fit into 3760 9 times, resulting in a remainder of 124.
Use 9 as the next digit of our solution. 
Result so far: 78044.193069
Subtracting 3636 from 3760 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 15:
1240 divided by 404 is 3 with a remainder of 28.
Record the quotient 3 as the next digit in the result. 
Result so far: 78044.1930693
If we subtract 1212 from 1240, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 16:
If we divide 280 by 404, we get 0 and a remainder of 280.
Write down 0 as next digit of the result. 
Result so far: 78044.1930693
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

The final outcome is 78044.1930693, with a leftover of 2.8e-07.
