We're dividing 11136403 by 549 
The aim is to understand the frequency of 549 in 11136403.

Advancing to step 1:
549 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 549

Advancing to step 2:
When dividing 11 by 549, we get 0 with a remainder of 11.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 11 leaves us with 11.
Fetch the next digit (1) from the dividend, attach it to 11 and continue: 111 / 549

Moving on to step 3:
When dividing 111 by 549, we get 0 with a remainder of 111.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 111 after subtracting 0 from 111.
Take the next digit (3) from the dividend and append it to 111, then repeat: 1113 / 549

Let's proceed to step 4:
The number 549 fits into 1113 2 times, leaving a remainder of 15.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 1098 from 1113 to get 15.
Append the next digit (6) from the dividend to 15 and continue with: 156 / 549

Step 5:
156 divided by 549 is 0 with a remainder of 156.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtracting 0 from 156 leaves us with 156.
Append the next digit (4) from the dividend to 156 and continue with: 1564 / 549

Step 6:
549 can be fit into 1564 2 times, resulting in a remainder of 466.
The next digit of our result is 2. 
Result so far: 202.0
Subtract 1098 from 1564 to get 466.
Take the next digit (0) from the dividend and append it to 466, then repeat: 4660 / 549

Advancing to step 7:
If we divide 4660 by 549, we get 8 and a remainder of 268.
Record the quotient 8 as the next digit in the result. 
Result so far: 2028.0
Subtracting 4392 from 4660 leaves us with 268.
Fetch the next digit (3) from the dividend, attach it to 268 and continue: 2683 / 549

Advancing to step 8:
When dividing 2683 by 549, we get 4 with a remainder of 487.
Record the quotient 4 as the next digit in the result. 
Result so far: 20284.0
Subtracting 2196 from 2683 leaves us with 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

On to step 9:
549 goes into 4870 8 times with a remainder of 478.
Write down 8 as next digit of the result. 
Result so far: 20284.8
Subtracting 4392 from 4870 leaves us with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

Advancing to step 10:
When dividing 4780 by 549, we get 8 with a remainder of 388.
Record the quotient 8 as the next digit in the result. 
Result so far: 20284.88
If we take 4392 away from 4780, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

After the division, we end up with 20284.88 and a remainder of 0.388.
