We look at the division of 99162114 by 236 
The aim is to understand the frequency of 236 in 99162114.

Step 1:
When dividing 9 by 236, we get 0 with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 236

Going ahead to step 2:
If we divide 99 by 236, we get 0 and a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 99 leaves us with 99.
Append the next digit (1) from the dividend to 99 and continue with: 991 / 236

On to step 3:
When dividing 991 by 236, we get 4 with a remainder of 47.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 944 from 991 and we're left with 47.
Bring next digit (6) of the dividend behind the 47 and repeat the process: 476 / 236

Advancing to step 4:
If we divide 476 by 236, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 42.0
Subtract 472 from 476 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 236

On to step 5:
42 divided by 236 is 0 with a remainder of 42.
The next digit of our result is 0. 
Result so far: 420.0
The remainder is 42 after subtracting 0 from 42.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 236

Going ahead to step 6:
If we divide 421 by 236, we get 1 and a remainder of 185.
The number 1 becomes the next digit in our result. 
Result so far: 4201.0
Subtract 236 from 421 to get 185.
Bring next digit (1) of the dividend behind the 185 and repeat the process: 1851 / 236

Moving on to step 7:
When dividing 1851 by 236, we get 7 with a remainder of 199.
The number 7 becomes the next digit in our result. 
Result so far: 42017.0
Deduct 1652 from 1851 and we're left with 199.
Bring next digit (4) of the dividend behind the 199 and repeat the process: 1994 / 236

Step 8:
236 goes into 1994 8 times with a remainder of 106.
Put 8 as the next digit of the answer. 
Result so far: 420178.0
Subtract 1888 from 1994 to get 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Going ahead to step 9:
If we divide 1060 by 236, we get 4 and a remainder of 116.
The number 4 becomes the next digit in our result. 
Result so far: 420178.4
The remainder is 116 after subtracting 944 from 1060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 10:
236 can be fit into 1160 4 times, resulting in a remainder of 216.
Record the quotient 4 as the next digit in the result. 
Result so far: 420178.44
Subtract 944 from 1160 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

After the division, we end up with 420178.44 and a remainder of 0.216.
