We're dividing 30259495 by 216 
The aim is to understand the frequency of 216 in 30259495.

On to step 1:
The number 216 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 216

Going ahead to step 2:
30 divided by 216 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 216

Let's proceed to step 3:
216 goes into 302 1 times with a remainder of 86.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 216 from 302, we get 86.
Take the next digit (5) from the dividend and append it to 86, then repeat: 865 / 216

Step 4:
216 can be fit into 865 4 times, resulting in a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we subtract 864 from 865, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 216

Advancing to step 5:
19 divided by 216 is 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 140.0
If we subtract 0 from 19, we get 19.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 216

Going ahead to step 6:
When dividing 194 by 216, we get 0 with a remainder of 194.
Write down 0 as next digit of the result. 
Result so far: 1400.0
If we take 0 away from 194, we end up with 194.
Bring next digit (9) of the dividend behind the 194 and repeat the process: 1949 / 216

On to step 7:
216 goes into 1949 9 times with a remainder of 5.
Record the quotient 9 as the next digit in the result. 
Result so far: 14009.0
If we take 1944 away from 1949, we end up with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 216

On to step 8:
The number 216 fits into 55 0 times, leaving a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 140090.0
The remainder is 55 after subtracting 0 from 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 9:
216 can be fit into 550 2 times, resulting in a remainder of 118.
The number 2 becomes the next digit in our result. 
Result so far: 140090.2
Subtracting 432 from 550 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Let's proceed to step 10:
216 goes into 1180 5 times with a remainder of 100.
The next digit of our result is 5. 
Result so far: 140090.25
If we take 1080 away from 1180, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Moving on to step 11:
1000 divided by 216 is 4 with a remainder of 136.
Record the quotient 4 as the next digit in the result. 
Result so far: 140090.254
Subtracting 864 from 1000 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Going ahead to step 12:
216 can be fit into 1360 6 times, resulting in a remainder of 64.
Put 6 as the next digit of the answer. 
Result so far: 140090.2546
Subtracting 1296 from 1360 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 13:
216 goes into 640 2 times with a remainder of 208.
The number 2 becomes the next digit in our result. 
Result so far: 140090.25462
Subtracting 432 from 640 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Step 14:
The number 216 fits into 2080 9 times, leaving a remainder of 136.
Record the quotient 9 as the next digit in the result. 
Result so far: 140090.254629
Subtract 1944 from 2080 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 15:
The number 216 fits into 1360 6 times, leaving a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 140090.2546296
If we subtract 1296 from 1360, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 16:
216 can be fit into 640 2 times, resulting in a remainder of 208.
The next digit of our result is 2. 
Result so far: 140090.25462962
Subtracting 432 from 640 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

The final outcome is 140090.25462962, with a leftover of 2.08e-07.
