We look at the division of 17918624 by 363 
The aim is to understand the frequency of 363 in 17918624.

Step 1:
363 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 363

Let's proceed to step 2:
If we divide 17 by 363, we get 0 and a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Bring next digit (9) of the dividend behind the 17 and repeat the process: 179 / 363

On to step 3:
The number 363 fits into 179 0 times, leaving a remainder of 179.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 179 to get 179.
Fetch the next digit (1) from the dividend, attach it to 179 and continue: 1791 / 363

Advancing to step 4:
363 goes into 1791 4 times with a remainder of 339.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 1452 from 1791 to get 339.
Grab the next digit (8) from the dividend, add it to 339, then carry on: 3398 / 363

Step 5:
If we divide 3398 by 363, we get 9 and a remainder of 131.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
If we subtract 3267 from 3398, we get 131.
Bring next digit (6) of the dividend behind the 131 and repeat the process: 1316 / 363

Let's proceed to step 6:
The number 363 fits into 1316 3 times, leaving a remainder of 227.
Record the quotient 3 as the next digit in the result. 
Result so far: 493.0
The remainder is 227 after subtracting 1089 from 1316.
Append the next digit (2) from the dividend to 227 and continue with: 2272 / 363

Moving on to step 7:
If we divide 2272 by 363, we get 6 and a remainder of 94.
The number 6 becomes the next digit in our result. 
Result so far: 4936.0
If we take 2178 away from 2272, we end up with 94.
Fetch the next digit (4) from the dividend, attach it to 94 and continue: 944 / 363

Advancing to step 8:
If we divide 944 by 363, we get 2 and a remainder of 218.
The number 2 becomes the next digit in our result. 
Result so far: 49362.0
Subtract 726 from 944 to get 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Let's proceed to step 9:
When dividing 2180 by 363, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 49362.6
Subtracting 2178 from 2180 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
363 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 49362.6
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
363 goes into 200 0 times with a remainder of 200.
The next digit of our result is 0. 
Result so far: 49362.6
If we subtract 0 from 200, we 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 final result is 49362.6 with a remainder of 0.02.
