86205114 divided by 251 
The aim is to understand the frequency of 251 in 86205114.

On to step 1:
The number 251 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 251

Moving on to step 2:
251 can be fit into 86 0 times, resulting in a remainder of 86.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Take the next digit (2) from the dividend and append it to 86, then repeat: 862 / 251

Step 3:
862 divided by 251 is 3 with a remainder of 109.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 109 after subtracting 753 from 862.
Include the next digit (0) from the dividend after 109, then repeat: 1090 / 251

Moving on to step 4:
1090 divided by 251 is 4 with a remainder of 86.
Write down 4 as next digit of the result. 
Result so far: 34.0
Deduct 1004 from 1090 and we're left with 86.
Include the next digit (5) from the dividend after 86, then repeat: 865 / 251

Going ahead to step 5:
865 divided by 251 is 3 with a remainder of 112.
The number 3 becomes the next digit in our result. 
Result so far: 343.0
The remainder is 112 after subtracting 753 from 865.
Bring next digit (1) of the dividend behind the 112 and repeat the process: 1121 / 251

Let's proceed to step 6:
The number 251 fits into 1121 4 times, leaving a remainder of 117.
The number 4 becomes the next digit in our result. 
Result so far: 3434.0
Subtracting 1004 from 1121 leaves us with 117.
Include the next digit (1) from the dividend after 117, then repeat: 1171 / 251

Moving on to step 7:
If we divide 1171 by 251, we get 4 and a remainder of 167.
The next digit of our result is 4. 
Result so far: 34344.0
If we take 1004 away from 1171, we end up with 167.
Include the next digit (4) from the dividend after 167, then repeat: 1674 / 251

Moving on to step 8:
251 goes into 1674 6 times with a remainder of 168.
The next digit of our result is 6. 
Result so far: 343446.0
Subtract 1506 from 1674 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Step 9:
The number 251 fits into 1680 6 times, leaving a remainder of 174.
The next digit of our result is 6. 
Result so far: 343446.6
Subtract 1506 from 1680 to get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

On to step 10:
The number 251 fits into 1740 6 times, leaving a remainder of 234.
Record the quotient 6 as the next digit in the result. 
Result so far: 343446.66
The remainder is 234 after subtracting 1506 from 1740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Our division results in 343446.66 with a remaining 0.234.
