We're dividing 23936908 by 216 
The aim is to understand the frequency of 216 in 23936908.

On to step 1:
2 divided by 216 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 216

On to step 2:
The number 216 fits into 23 0 times, leaving a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Fetch the next digit (9) from the dividend, attach it to 23 and continue: 239 / 216

Let's proceed to step 3:
If we divide 239 by 216, we get 1 and a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 216 from 239, we get 23.
Fetch the next digit (3) from the dividend, attach it to 23 and continue: 233 / 216

Let's proceed to step 4:
The number 216 fits into 233 1 times, leaving a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we take 216 away from 233, we end up with 17.
Append the next digit (6) from the dividend to 17 and continue with: 176 / 216

Let's proceed to step 5:
If we divide 176 by 216, we get 0 and a remainder of 176.
Write down 0 as next digit of the result. 
Result so far: 110.0
If we subtract 0 from 176, we get 176.
Fetch the next digit (9) from the dividend, attach it to 176 and continue: 1769 / 216

Step 6:
1769 divided by 216 is 8 with a remainder of 41.
The number 8 becomes the next digit in our result. 
Result so far: 1108.0
Subtract 1728 from 1769 to get 41.
Bring next digit (0) of the dividend behind the 41 and repeat the process: 410 / 216

Advancing to step 7:
216 can be fit into 410 1 times, resulting in a remainder of 194.
The number 1 becomes the next digit in our result. 
Result so far: 11081.0
If we subtract 216 from 410, we get 194.
Append the next digit (8) from the dividend to 194 and continue with: 1948 / 216

On to step 8:
If we divide 1948 by 216, we get 9 and a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 110819.0
Deduct 1944 from 1948 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
When dividing 40 by 216, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 110819.0
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
216 can be fit into 400 1 times, resulting in a remainder of 184.
Put 1 as the next digit of the answer. 
Result so far: 110819.01
Subtracting 216 from 400 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 11:
1840 divided by 216 is 8 with a remainder of 112.
Record the quotient 8 as the next digit in the result. 
Result so far: 110819.018
Subtract 1728 from 1840 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Let's proceed to step 12:
When dividing 1120 by 216, we get 5 with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 110819.0185
Subtract 1080 from 1120 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
216 goes into 400 1 times with a remainder of 184.
Put 1 as the next digit of the answer. 
Result so far: 110819.01851
Deduct 216 from 400 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 14:
216 goes into 1840 8 times with a remainder of 112.
Write down 8 as next digit of the result. 
Result so far: 110819.018518
If we take 1728 away from 1840, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 15:
When dividing 1120 by 216, we get 5 with a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 110819.0185185
If we subtract 1080 from 1120, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 16:
If we divide 400 by 216, we get 1 and a remainder of 184.
The next digit of our result is 1. 
Result so far: 110819.01851851
If we take 216 away from 400, we end up with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The final result is 110819.01851851 with a remainder of 1.84e-07.
