We're dividing 12888460 by 404 
The aim is to understand the frequency of 404 in 12888460.

Moving on to step 1:
404 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 404

On to step 2:
12 divided by 404 is 0 with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 404

On to step 3:
404 goes into 128 0 times with a remainder of 128.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 128, we get 128.
Include the next digit (8) from the dividend after 128, then repeat: 1288 / 404

Moving on to step 4:
If we divide 1288 by 404, we get 3 and a remainder of 76.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 1212 away from 1288, we end up with 76.
Grab the next digit (8) from the dividend, add it to 76, then carry on: 768 / 404

On to step 5:
If we divide 768 by 404, we get 1 and a remainder of 364.
The next digit of our result is 1. 
Result so far: 31.0
Subtracting 404 from 768 leaves us with 364.
Include the next digit (4) from the dividend after 364, then repeat: 3644 / 404

On to step 6:
404 can be fit into 3644 9 times, resulting in a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 319.0
Subtracting 3636 from 3644 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 404

Let's proceed to step 7:
The number 404 fits into 86 0 times, leaving a remainder of 86.
The next digit of our result is 0. 
Result so far: 3190.0
Deduct 0 from 86 and we're left with 86.
Append the next digit (0) from the dividend to 86 and continue with: 860 / 404

Let's proceed to step 8:
404 goes into 860 2 times with a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 31902.0
Subtract 808 from 860 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 9:
404 can be fit into 520 1 times, resulting in a remainder of 116.
Record the quotient 1 as the next digit in the result. 
Result so far: 31902.1
The remainder is 116 after subtracting 404 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 10:
The number 404 fits into 1160 2 times, leaving a remainder of 352.
Use 2 as the next digit of our solution. 
Result so far: 31902.12
If we subtract 808 from 1160, we get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 11:
The number 404 fits into 3520 8 times, leaving a remainder of 288.
Write down 8 as next digit of the result. 
Result so far: 31902.128
If we subtract 3232 from 3520, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 12:
When dividing 2880 by 404, we get 7 with a remainder of 52.
Use 7 as the next digit of our solution. 
Result so far: 31902.1287
Subtracting 2828 from 2880 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 13:
The number 404 fits into 520 1 times, leaving a remainder of 116.
Use 1 as the next digit of our solution. 
Result so far: 31902.12871
The remainder is 116 after subtracting 404 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 14:
When dividing 1160 by 404, we get 2 with a remainder of 352.
Write down 2 as next digit of the result. 
Result so far: 31902.128712
Subtract 808 from 1160 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 15:
404 goes into 3520 8 times with a remainder of 288.
Write down 8 as next digit of the result. 
Result so far: 31902.1287128
Subtract 3232 from 3520 to get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Moving on to step 16:
When dividing 2880 by 404, we get 7 with a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 31902.12871287
Subtract 2828 from 2880 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 31902.12871287, with a leftover of 5.2e-08.
