250311 ÷ 86 
The aim is to understand the frequency of 86 in 250311.

Advancing to step 1:
86 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 86

Moving on to step 2:
The number 86 fits into 25 0 times, leaving a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Fetch the next digit (0) from the dividend, attach it to 25 and continue: 250 / 86

Advancing to step 3:
When dividing 250 by 86, we get 2 with a remainder of 78.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 172 from 250, we get 78.
Append the next digit (3) from the dividend to 78 and continue with: 783 / 86

Let's proceed to step 4:
783 divided by 86 is 9 with a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
Subtracting 774 from 783 leaves us with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 86

Step 5:
When dividing 91 by 86, we get 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 291.0
If we subtract 86 from 91, we get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 86

Moving on to step 6:
51 divided by 86 is 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 2910.0
The remainder is 51 after subtracting 0 from 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Advancing to step 7:
The number 86 fits into 510 5 times, leaving a remainder of 80.
The next digit of our result is 5. 
Result so far: 2910.5
Subtract 430 from 510 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 8:
If we divide 800 by 86, we get 9 and a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 2910.59
If we take 774 away from 800, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
If we divide 260 by 86, we get 3 and a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 2910.593
Deduct 258 from 260 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
86 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 2910.593
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
If we divide 200 by 86, we get 2 and a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 2910.59302
Subtracting 172 from 200 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
The number 86 fits into 280 3 times, leaving a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 2910.593023
The remainder is 22 after subtracting 258 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 13:
86 can be fit into 220 2 times, resulting in a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 2910.5930232
Subtract 172 from 220 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 14:
If we divide 480 by 86, we get 5 and a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 2910.59302325
Subtracting 430 from 480 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 2910.59302325 with a balance of 5e-08.
