We look at the division of 11289230 by 403 
The aim is to understand the frequency of 403 in 11289230.

Advancing to step 1:
When dividing 1 by 403, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 403

Going ahead to step 2:
403 goes into 11 0 times with a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 403

On to step 3:
The number 403 fits into 112 0 times, leaving a remainder of 112.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 112 and we're left with 112.
Fetch the next digit (8) from the dividend, attach it to 112 and continue: 1128 / 403

Moving on to step 4:
403 can be fit into 1128 2 times, resulting in a remainder of 322.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 322 after subtracting 806 from 1128.
Append the next digit (9) from the dividend to 322 and continue with: 3229 / 403

On to step 5:
403 goes into 3229 8 times with a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Deduct 3224 from 3229 and we're left with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 403

Advancing to step 6:
52 divided by 403 is 0 with a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 280.0
Deduct 0 from 52 and we're left with 52.
Grab the next digit (3) from the dividend, add it to 52, then carry on: 523 / 403

On to step 7:
403 goes into 523 1 times with a remainder of 120.
Use 1 as the next digit of our solution. 
Result so far: 2801.0
If we take 403 away from 523, we end up with 120.
Fetch the next digit (0) from the dividend, attach it to 120 and continue: 1200 / 403

Advancing to step 8:
When dividing 1200 by 403, we get 2 with a remainder of 394.
Use 2 as the next digit of our solution. 
Result so far: 28012.0
If we subtract 806 from 1200, we get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Let's proceed to step 9:
When dividing 3940 by 403, we get 9 with a remainder of 313.
The number 9 becomes the next digit in our result. 
Result so far: 28012.9
The remainder is 313 after subtracting 3627 from 3940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Advancing to step 10:
When dividing 3130 by 403, we get 7 with a remainder of 309.
Write down 7 as next digit of the result. 
Result so far: 28012.97
If we take 2821 away from 3130, we end up with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Going ahead to step 11:
The number 403 fits into 3090 7 times, leaving a remainder of 269.
Put 7 as the next digit of the answer. 
Result so far: 28012.977
Deduct 2821 from 3090 and we're left with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

The final outcome is 28012.977, with a leftover of 0.0269.
