64475957 divided by 404 
The aim is to understand the frequency of 404 in 64475957.

Let's proceed to step 1:
404 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 404

Going ahead to step 2:
When dividing 64 by 404, we get 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Include the next digit (4) from the dividend after 64, then repeat: 644 / 404

Step 3:
When dividing 644 by 404, we get 1 with a remainder of 240.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 404 from 644, we get 240.
Append the next digit (7) from the dividend to 240 and continue with: 2407 / 404

Advancing to step 4:
The number 404 fits into 2407 5 times, leaving a remainder of 387.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 387 after subtracting 2020 from 2407.
Take the next digit (5) from the dividend and append it to 387, then repeat: 3875 / 404

Moving on to step 5:
404 goes into 3875 9 times with a remainder of 239.
The next digit of our result is 9. 
Result so far: 159.0
If we take 3636 away from 3875, we end up with 239.
Take the next digit (9) from the dividend and append it to 239, then repeat: 2399 / 404

Advancing to step 6:
When dividing 2399 by 404, we get 5 with a remainder of 379.
The number 5 becomes the next digit in our result. 
Result so far: 1595.0
Deduct 2020 from 2399 and we're left with 379.
Append the next digit (5) from the dividend to 379 and continue with: 3795 / 404

Let's proceed to step 7:
404 can be fit into 3795 9 times, resulting in a remainder of 159.
Put 9 as the next digit of the answer. 
Result so far: 15959.0
If we subtract 3636 from 3795, we get 159.
Append the next digit (7) from the dividend to 159 and continue with: 1597 / 404

On to step 8:
If we divide 1597 by 404, we get 3 and a remainder of 385.
Write down 3 as next digit of the result. 
Result so far: 159593.0
The remainder is 385 after subtracting 1212 from 1597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Going ahead to step 9:
If we divide 3850 by 404, we get 9 and a remainder of 214.
The number 9 becomes the next digit in our result. 
Result so far: 159593.9
Subtract 3636 from 3850 to get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 10:
404 can be fit into 2140 5 times, resulting in a remainder of 120.
The number 5 becomes the next digit in our result. 
Result so far: 159593.95
The remainder is 120 after subtracting 2020 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 11:
404 goes into 1200 2 times with a remainder of 392.
Write down 2 as next digit of the result. 
Result so far: 159593.952
If we subtract 808 from 1200, we get 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Step 12:
The number 404 fits into 3920 9 times, leaving a remainder of 284.
The next digit of our result is 9. 
Result so far: 159593.9529
If we subtract 3636 from 3920, we get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Going ahead to step 13:
404 goes into 2840 7 times with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 159593.95297
Subtract 2828 from 2840 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 14:
If we divide 120 by 404, we get 0 and a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 159593.95297
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 15:
The number 404 fits into 1200 2 times, leaving a remainder of 392.
Write down 2 as next digit of the result. 
Result so far: 159593.9529702
If we take 808 away from 1200, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Advancing to step 16:
404 can be fit into 3920 9 times, resulting in a remainder of 284.
The number 9 becomes the next digit in our result. 
Result so far: 159593.95297029
Subtract 3636 from 3920 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

The final outcome is 159593.95297029, with a leftover of 2.84e-07.
