We look at the division of 8755216 by 236 
The aim is to understand the frequency of 236 in 8755216.

On to step 1:
When dividing 8 by 236, we get 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 236

On to step 2:
236 can be fit into 87 0 times, resulting in a remainder of 87.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Append the next digit (5) from the dividend to 87 and continue with: 875 / 236

Let's proceed to step 3:
When dividing 875 by 236, we get 3 with a remainder of 167.
The next digit of our result is 3. 
Result so far: 3.0
If we take 708 away from 875, we end up with 167.
Fetch the next digit (5) from the dividend, attach it to 167 and continue: 1675 / 236

Going ahead to step 4:
1675 divided by 236 is 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 37.0
If we subtract 1652 from 1675, we get 23.
Fetch the next digit (2) from the dividend, attach it to 23 and continue: 232 / 236

Advancing to step 5:
236 goes into 232 0 times with a remainder of 232.
Record the quotient 0 as the next digit in the result. 
Result so far: 370.0
Subtracting 0 from 232 leaves us with 232.
Grab the next digit (1) from the dividend, add it to 232, then carry on: 2321 / 236

Advancing to step 6:
The number 236 fits into 2321 9 times, leaving a remainder of 197.
The next digit of our result is 9. 
Result so far: 3709.0
Subtracting 2124 from 2321 leaves us with 197.
Append the next digit (6) from the dividend to 197 and continue with: 1976 / 236

Advancing to step 7:
236 can be fit into 1976 8 times, resulting in a remainder of 88.
Write down 8 as next digit of the result. 
Result so far: 37098.0
Subtracting 1888 from 1976 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

On to step 8:
The number 236 fits into 880 3 times, leaving a remainder of 172.
Record the quotient 3 as the next digit in the result. 
Result so far: 37098.3
The remainder is 172 after subtracting 708 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 9:
When dividing 1720 by 236, we get 7 with a remainder of 68.
Write down 7 as next digit of the result. 
Result so far: 37098.37
Subtract 1652 from 1720 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 10:
When dividing 680 by 236, we get 2 with a remainder of 208.
Write down 2 as next digit of the result. 
Result so far: 37098.372
If we take 472 away from 680, we end up 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.

Advancing to step 11:
236 can be fit into 2080 8 times, resulting in a remainder of 192.
Use 8 as the next digit of our solution. 
Result so far: 37098.3728
Deduct 1888 from 2080 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Advancing to step 12:
When dividing 1920 by 236, we get 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 37098.37288
If we take 1888 away from 1920, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 37098.37288 with a remainder of 3.2e-05.
