We're dividing 17438522 by 363 
The aim is to understand the frequency of 363 in 17438522.

Advancing to step 1:
The number 363 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 363

On to step 2:
When dividing 17 by 363, we get 0 with a remainder of 17.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Include the next digit (4) from the dividend after 17, then repeat: 174 / 363

Let's proceed to step 3:
If we divide 174 by 363, we get 0 and a remainder of 174.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 174 after subtracting 0 from 174.
Fetch the next digit (3) from the dividend, attach it to 174 and continue: 1743 / 363

Advancing to step 4:
363 goes into 1743 4 times with a remainder of 291.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 1452 away from 1743, we end up with 291.
Take the next digit (8) from the dividend and append it to 291, then repeat: 2918 / 363

Let's proceed to step 5:
363 goes into 2918 8 times with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Deduct 2904 from 2918 and we're left with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 363

On to step 6:
If we divide 145 by 363, we get 0 and a remainder of 145.
The next digit of our result is 0. 
Result so far: 480.0
Subtracting 0 from 145 leaves us with 145.
Append the next digit (2) from the dividend to 145 and continue with: 1452 / 363

Let's proceed to step 7:
If we divide 1452 by 363, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4804.0
The remainder is 0 after subtracting 1452 from 1452.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 363

Moving on to step 8:
The number 363 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 48040.0
If we subtract 0 from 2, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
363 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 48040.0
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
363 can be fit into 200 0 times, resulting in a remainder of 200.
The number 0 becomes the next digit in our result. 
Result so far: 48040.0
Subtract 0 from 200 to get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The quotient of the division is 48040.0, and the remainder is 0.2.
