We look at the division of 28151385 by 236 
The aim is to understand the frequency of 236 in 28151385.

Going ahead to step 1:
2 divided by 236 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 236

Going ahead to step 2:
When dividing 28 by 236, we get 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Grab the next digit (1) from the dividend, add it to 28, then carry on: 281 / 236

Advancing to step 3:
If we divide 281 by 236, we get 1 and a remainder of 45.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 236 away from 281, we end up with 45.
Take the next digit (5) from the dividend and append it to 45, then repeat: 455 / 236

Going ahead to step 4:
236 goes into 455 1 times with a remainder of 219.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 236 from 455 and we're left with 219.
Fetch the next digit (1) from the dividend, attach it to 219 and continue: 2191 / 236

On to step 5:
236 can be fit into 2191 9 times, resulting in a remainder of 67.
Record the quotient 9 as the next digit in the result. 
Result so far: 119.0
If we subtract 2124 from 2191, we get 67.
Fetch the next digit (3) from the dividend, attach it to 67 and continue: 673 / 236

Advancing to step 6:
If we divide 673 by 236, we get 2 and a remainder of 201.
Use 2 as the next digit of our solution. 
Result so far: 1192.0
Subtracting 472 from 673 leaves us with 201.
Include the next digit (8) from the dividend after 201, then repeat: 2018 / 236

Let's proceed to step 7:
2018 divided by 236 is 8 with a remainder of 130.
The number 8 becomes the next digit in our result. 
Result so far: 11928.0
Subtracting 1888 from 2018 leaves us with 130.
Include the next digit (5) from the dividend after 130, then repeat: 1305 / 236

Let's proceed to step 8:
236 goes into 1305 5 times with a remainder of 125.
The number 5 becomes the next digit in our result. 
Result so far: 119285.0
Deduct 1180 from 1305 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Going ahead to step 9:
236 goes into 1250 5 times with a remainder of 70.
Record the quotient 5 as the next digit in the result. 
Result so far: 119285.5
The remainder is 70 after subtracting 1180 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 10:
700 divided by 236 is 2 with a remainder of 228.
The number 2 becomes the next digit in our result. 
Result so far: 119285.52
Deduct 472 from 700 and we're left with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Going ahead to step 11:
If we divide 2280 by 236, we get 9 and a remainder of 156.
The next digit of our result is 9. 
Result so far: 119285.529
The remainder is 156 after subtracting 2124 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Advancing to step 12:
236 goes into 1560 6 times with a remainder of 144.
Write down 6 as next digit of the result. 
Result so far: 119285.5296
Deduct 1416 from 1560 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Let's proceed to step 13:
236 can be fit into 1440 6 times, resulting in a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 119285.52966
The remainder is 24 after subtracting 1416 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 119285.52966 with a balance of 2.4e-05.
