We're dividing 28485383 by 403 
The aim is to understand the frequency of 403 in 28485383.

Going ahead to step 1:
403 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 403

Step 2:
If we divide 28 by 403, we get 0 and a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 403

Going ahead to step 3:
The number 403 fits into 284 0 times, leaving a remainder of 284.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 284, we get 284.
Bring next digit (8) of the dividend behind the 284 and repeat the process: 2848 / 403

Going ahead to step 4:
The number 403 fits into 2848 7 times, leaving a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 2821 from 2848 leaves us with 27.
Bring next digit (5) of the dividend behind the 27 and repeat the process: 275 / 403

Advancing to step 5:
When dividing 275 by 403, we get 0 with a remainder of 275.
Write down 0 as next digit of the result. 
Result so far: 70.0
If we subtract 0 from 275, we get 275.
Append the next digit (3) from the dividend to 275 and continue with: 2753 / 403

On to step 6:
2753 divided by 403 is 6 with a remainder of 335.
Use 6 as the next digit of our solution. 
Result so far: 706.0
If we subtract 2418 from 2753, we get 335.
Bring next digit (8) of the dividend behind the 335 and repeat the process: 3358 / 403

Advancing to step 7:
403 can be fit into 3358 8 times, resulting in a remainder of 134.
Put 8 as the next digit of the answer. 
Result so far: 7068.0
Subtracting 3224 from 3358 leaves us with 134.
Take the next digit (3) from the dividend and append it to 134, then repeat: 1343 / 403

Moving on to step 8:
403 goes into 1343 3 times with a remainder of 134.
The number 3 becomes the next digit in our result. 
Result so far: 70683.0
Subtract 1209 from 1343 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 9:
403 goes into 1340 3 times with a remainder of 131.
Use 3 as the next digit of our solution. 
Result so far: 70683.3
If we take 1209 away from 1340, we end up with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

On to step 10:
403 goes into 1310 3 times with a remainder of 101.
Record the quotient 3 as the next digit in the result. 
Result so far: 70683.33
If we subtract 1209 from 1310, we get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

The quotient of the division is 70683.33, and the remainder is 0.101.
