We look at the division of 18728695 by 803 
The aim is to understand the frequency of 803 in 18728695.

Advancing to step 1:
803 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 803

Advancing to step 2:
If we divide 18 by 803, we get 0 and a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 803

Step 3:
If we divide 187 by 803, we get 0 and a remainder of 187.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 187 leaves us with 187.
Take the next digit (2) from the dividend and append it to 187, then repeat: 1872 / 803

Moving on to step 4:
803 can be fit into 1872 2 times, resulting in a remainder of 266.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1606 away from 1872, we end up with 266.
Append the next digit (8) from the dividend to 266 and continue with: 2668 / 803

Moving on to step 5:
803 goes into 2668 3 times with a remainder of 259.
Put 3 as the next digit of the answer. 
Result so far: 23.0
If we subtract 2409 from 2668, we get 259.
Take the next digit (6) from the dividend and append it to 259, then repeat: 2596 / 803

Advancing to step 6:
The number 803 fits into 2596 3 times, leaving a remainder of 187.
Record the quotient 3 as the next digit in the result. 
Result so far: 233.0
Subtract 2409 from 2596 to get 187.
Bring next digit (9) of the dividend behind the 187 and repeat the process: 1879 / 803

Going ahead to step 7:
803 goes into 1879 2 times with a remainder of 273.
Use 2 as the next digit of our solution. 
Result so far: 2332.0
If we subtract 1606 from 1879, we get 273.
Take the next digit (5) from the dividend and append it to 273, then repeat: 2735 / 803

Advancing to step 8:
The number 803 fits into 2735 3 times, leaving a remainder of 326.
Put 3 as the next digit of the answer. 
Result so far: 23323.0
If we take 2409 away from 2735, we end up with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Let's proceed to step 9:
803 can be fit into 3260 4 times, resulting in a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 23323.4
Subtract 3212 from 3260 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 10:
480 divided by 803 is 0 with a remainder of 480.
Put 0 as the next digit of the answer. 
Result so far: 23323.4
Subtracting 0 from 480 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 11:
4800 divided by 803 is 5 with a remainder of 785.
Record the quotient 5 as the next digit in the result. 
Result so far: 23323.405
Subtract 4015 from 4800 to get 785.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7850, and continue the process.

Advancing to step 12:
803 goes into 7850 9 times with a remainder of 623.
Put 9 as the next digit of the answer. 
Result so far: 23323.4059
The remainder is 623 after subtracting 7227 from 7850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Let's proceed to step 13:
803 goes into 6230 7 times with a remainder of 609.
Use 7 as the next digit of our solution. 
Result so far: 23323.40597
The remainder is 609 after subtracting 5621 from 6230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

Moving on to step 14:
6090 divided by 803 is 7 with a remainder of 469.
Write down 7 as next digit of the result. 
Result so far: 23323.405977
Subtract 5621 from 6090 to get 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

The quotient of the division is 23323.405977, and the remainder is 4.69e-05.
