21275864 ÷ 360 
The aim is to understand the frequency of 360 in 21275864.

Moving on to step 1:
360 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 360

Advancing to step 2:
The number 360 fits into 21 0 times, leaving a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (2) from the dividend and append it to 21, then repeat: 212 / 360

Going ahead to step 3:
360 goes into 212 0 times with a remainder of 212.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 212, we get 212.
Take the next digit (7) from the dividend and append it to 212, then repeat: 2127 / 360

Let's proceed to step 4:
360 can be fit into 2127 5 times, resulting in a remainder of 327.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 327 after subtracting 1800 from 2127.
Bring next digit (5) of the dividend behind the 327 and repeat the process: 3275 / 360

Moving on to step 5:
If we divide 3275 by 360, we get 9 and a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 59.0
The remainder is 35 after subtracting 3240 from 3275.
Append the next digit (8) from the dividend to 35 and continue with: 358 / 360

Let's proceed to step 6:
360 can be fit into 358 0 times, resulting in a remainder of 358.
Record the quotient 0 as the next digit in the result. 
Result so far: 590.0
If we take 0 away from 358, we end up with 358.
Include the next digit (6) from the dividend after 358, then repeat: 3586 / 360

Moving on to step 7:
360 can be fit into 3586 9 times, resulting in a remainder of 346.
The next digit of our result is 9. 
Result so far: 5909.0
The remainder is 346 after subtracting 3240 from 3586.
Include the next digit (4) from the dividend after 346, then repeat: 3464 / 360

On to step 8:
360 goes into 3464 9 times with a remainder of 224.
Use 9 as the next digit of our solution. 
Result so far: 59099.0
Subtract 3240 from 3464 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 9:
When dividing 2240 by 360, we get 6 with a remainder of 80.
The number 6 becomes the next digit in our result. 
Result so far: 59099.6
Deduct 2160 from 2240 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 10:
800 divided by 360 is 2 with a remainder of 80.
Write down 2 as next digit of the result. 
Result so far: 59099.62
Subtracting 720 from 800 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
360 goes into 800 2 times with a remainder of 80.
The next digit of our result is 2. 
Result so far: 59099.622
Deduct 720 from 800 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Our division results in 59099.622 with a remaining 0.008.
