Let's divide 19030115 by 456
The aim is to understand the frequency of 456 in 19030115.

On to step 1:
1 divided by 456 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 456

Step 2:
456 goes into 19 0 times with a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 19 leaves us with 19.
Fetch the next digit (0) from the dividend, attach it to 19 and continue: 190 / 456

Advancing to step 3:
456 can be fit into 190 0 times, resulting in a remainder of 190.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 190 after subtracting 0 from 190.
Include the next digit (3) from the dividend after 190, then repeat: 1903 / 456

Step 4:
456 can be fit into 1903 4 times, resulting in a remainder of 79.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 1824 from 1903 leaves us with 79.
Take the next digit (0) from the dividend and append it to 79, then repeat: 790 / 456

Advancing to step 5:
456 goes into 790 1 times with a remainder of 334.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Deduct 456 from 790 and we're left with 334.
Fetch the next digit (1) from the dividend, attach it to 334 and continue: 3341 / 456

Let's proceed to step 6:
If we divide 3341 by 456, we get 7 and a remainder of 149.
Record the quotient 7 as the next digit in the result. 
Result so far: 417.0
The remainder is 149 after subtracting 3192 from 3341.
Fetch the next digit (1) from the dividend, attach it to 149 and continue: 1491 / 456

On to step 7:
The number 456 fits into 1491 3 times, leaving a remainder of 123.
The number 3 becomes the next digit in our result. 
Result so far: 4173.0
Subtract 1368 from 1491 to get 123.
Include the next digit (5) from the dividend after 123, then repeat: 1235 / 456

On to step 8:
When dividing 1235 by 456, we get 2 with a remainder of 323.
Record the quotient 2 as the next digit in the result. 
Result so far: 41732.0
Subtracting 912 from 1235 leaves us with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

On to step 9:
If we divide 3230 by 456, we get 7 and a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 41732.7
If we subtract 3192 from 3230, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 10:
456 can be fit into 380 0 times, resulting in a remainder of 380.
Use 0 as the next digit of our solution. 
Result so far: 41732.7
The remainder is 380 after subtracting 0 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Step 11:
If we divide 3800 by 456, we get 8 and a remainder of 152.
The number 8 becomes the next digit in our result. 
Result so far: 41732.708
Subtract 3648 from 3800 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 12:
456 goes into 1520 3 times with a remainder of 152.
The next digit of our result is 3. 
Result so far: 41732.7083
Deduct 1368 from 1520 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 13:
When dividing 1520 by 456, we get 3 with a remainder of 152.
The next digit of our result is 3. 
Result so far: 41732.70833
If we take 1368 away from 1520, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

After the division, we end up with 41732.70833 and a remainder of 0.000152.
