We divide 19190379 by 404
The aim is to understand the frequency of 404 in 19190379.

On to step 1:
If we divide 1 by 404, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 404

Step 2:
When dividing 19 by 404, we get 0 with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 404

Step 3:
The number 404 fits into 191 0 times, leaving a remainder of 191.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 191, we get 191.
Fetch the next digit (9) from the dividend, attach it to 191 and continue: 1919 / 404

On to step 4:
404 goes into 1919 4 times with a remainder of 303.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 1616 away from 1919, we end up with 303.
Bring next digit (0) of the dividend behind the 303 and repeat the process: 3030 / 404

Advancing to step 5:
404 goes into 3030 7 times with a remainder of 202.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
If we subtract 2828 from 3030, we get 202.
Append the next digit (3) from the dividend to 202 and continue with: 2023 / 404

Advancing to step 6:
404 can be fit into 2023 5 times, resulting in a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 475.0
Subtracting 2020 from 2023 leaves us with 3.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 404

On to step 7:
404 can be fit into 37 0 times, resulting in a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 4750.0
Subtract 0 from 37 to get 37.
Grab the next digit (9) from the dividend, add it to 37, then carry on: 379 / 404

Advancing to step 8:
379 divided by 404 is 0 with a remainder of 379.
Put 0 as the next digit of the answer. 
Result so far: 47500.0
If we subtract 0 from 379, we get 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Step 9:
404 goes into 3790 9 times with a remainder of 154.
The next digit of our result is 9. 
Result so far: 47500.9
If we subtract 3636 from 3790, we get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

On to step 10:
404 goes into 1540 3 times with a remainder of 328.
Write down 3 as next digit of the result. 
Result so far: 47500.93
Subtracting 1212 from 1540 leaves us with 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Step 11:
When dividing 3280 by 404, we get 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 47500.938
If we take 3232 away from 3280, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 12:
The number 404 fits into 480 1 times, leaving a remainder of 76.
The next digit of our result is 1. 
Result so far: 47500.9381
Subtract 404 from 480 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 13:
404 can be fit into 760 1 times, resulting in a remainder of 356.
Put 1 as the next digit of the answer. 
Result so far: 47500.93811
The remainder is 356 after subtracting 404 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

The quotient of the division is 47500.93811, and the remainder is 0.000356.
