We're dividing 30687291 by 363 
The aim is to understand the frequency of 363 in 30687291.

Let's proceed to step 1:
The number 363 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 363

Advancing to step 2:
363 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 30 leaves us with 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 363

Advancing to step 3:
If we divide 306 by 363, we get 0 and a remainder of 306.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 306 leaves us with 306.
Fetch the next digit (8) from the dividend, attach it to 306 and continue: 3068 / 363

Moving on to step 4:
When dividing 3068 by 363, we get 8 with a remainder of 164.
The next digit of our result is 8. 
Result so far: 8.0
If we take 2904 away from 3068, we end up with 164.
Grab the next digit (7) from the dividend, add it to 164, then carry on: 1647 / 363

On to step 5:
The number 363 fits into 1647 4 times, leaving a remainder of 195.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
If we subtract 1452 from 1647, we get 195.
Include the next digit (2) from the dividend after 195, then repeat: 1952 / 363

Step 6:
1952 divided by 363 is 5 with a remainder of 137.
Put 5 as the next digit of the answer. 
Result so far: 845.0
The remainder is 137 after subtracting 1815 from 1952.
Grab the next digit (9) from the dividend, add it to 137, then carry on: 1379 / 363

Step 7:
363 goes into 1379 3 times with a remainder of 290.
Use 3 as the next digit of our solution. 
Result so far: 8453.0
If we take 1089 away from 1379, we end up with 290.
Fetch the next digit (1) from the dividend, attach it to 290 and continue: 2901 / 363

Step 8:
When dividing 2901 by 363, we get 7 with a remainder of 360.
The next digit of our result is 7. 
Result so far: 84537.0
If we subtract 2541 from 2901, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Going ahead to step 9:
363 can be fit into 3600 9 times, resulting in a remainder of 333.
Write down 9 as next digit of the result. 
Result so far: 84537.9
Deduct 3267 from 3600 and we're left with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

Moving on to step 10:
The number 363 fits into 3330 9 times, leaving a remainder of 63.
Write down 9 as next digit of the result. 
Result so far: 84537.99
Deduct 3267 from 3330 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Our division results in 84537.99 with a remaining 0.063.
