We're dividing 86321631 by 236 
The aim is to understand the frequency of 236 in 86321631.

Advancing to step 1:
236 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 236

Let's proceed to step 2:
236 can be fit into 86 0 times, resulting in a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Fetch the next digit (3) from the dividend, attach it to 86 and continue: 863 / 236

Let's proceed to step 3:
236 goes into 863 3 times with a remainder of 155.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 708 from 863 to get 155.
Grab the next digit (2) from the dividend, add it to 155, then carry on: 1552 / 236

On to step 4:
1552 divided by 236 is 6 with a remainder of 136.
The next digit of our result is 6. 
Result so far: 36.0
If we take 1416 away from 1552, we end up with 136.
Include the next digit (1) from the dividend after 136, then repeat: 1361 / 236

Let's proceed to step 5:
If we divide 1361 by 236, we get 5 and a remainder of 181.
Use 5 as the next digit of our solution. 
Result so far: 365.0
If we take 1180 away from 1361, we end up with 181.
Bring next digit (6) of the dividend behind the 181 and repeat the process: 1816 / 236

On to step 6:
236 goes into 1816 7 times with a remainder of 164.
Record the quotient 7 as the next digit in the result. 
Result so far: 3657.0
If we subtract 1652 from 1816, we get 164.
Take the next digit (3) from the dividend and append it to 164, then repeat: 1643 / 236

Going ahead to step 7:
The number 236 fits into 1643 6 times, leaving a remainder of 227.
The next digit of our result is 6. 
Result so far: 36576.0
The remainder is 227 after subtracting 1416 from 1643.
Take the next digit (1) from the dividend and append it to 227, then repeat: 2271 / 236

Advancing to step 8:
The number 236 fits into 2271 9 times, leaving a remainder of 147.
The number 9 becomes the next digit in our result. 
Result so far: 365769.0
If we take 2124 away from 2271, we end up with 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Moving on to step 9:
1470 divided by 236 is 6 with a remainder of 54.
Record the quotient 6 as the next digit in the result. 
Result so far: 365769.6
Subtract 1416 from 1470 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 10:
540 divided by 236 is 2 with a remainder of 68.
Write down 2 as next digit of the result. 
Result so far: 365769.62
Deduct 472 from 540 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 11:
When dividing 680 by 236, we get 2 with a remainder of 208.
The next digit of our result is 2. 
Result so far: 365769.622
The remainder is 208 after subtracting 472 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Our division results in 365769.622 with a remaining 0.0208.
