We look at the division of 341985 by 86 
The aim is to understand the frequency of 86 in 341985.

Moving on to step 1:
86 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 86

Moving on to step 2:
86 can be fit into 34 0 times, resulting in a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Take the next digit (1) from the dividend and append it to 34, then repeat: 341 / 86

Let's proceed to step 3:
The number 86 fits into 341 3 times, leaving a remainder of 83.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 258 from 341 to get 83.
Include the next digit (9) from the dividend after 83, then repeat: 839 / 86

Advancing to step 4:
86 can be fit into 839 9 times, resulting in a remainder of 65.
Write down 9 as next digit of the result. 
Result so far: 39.0
Deduct 774 from 839 and we're left with 65.
Include the next digit (8) from the dividend after 65, then repeat: 658 / 86

Let's proceed to step 5:
The number 86 fits into 658 7 times, leaving a remainder of 56.
The number 7 becomes the next digit in our result. 
Result so far: 397.0
If we take 602 away from 658, we end up with 56.
Append the next digit (5) from the dividend to 56 and continue with: 565 / 86

Moving on to step 6:
86 can be fit into 565 6 times, resulting in a remainder of 49.
The next digit of our result is 6. 
Result so far: 3976.0
If we subtract 516 from 565, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 7:
86 can be fit into 490 5 times, resulting in a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 3976.5
If we subtract 430 from 490, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
86 can be fit into 600 6 times, resulting in a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 3976.56
Deduct 516 from 600 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 9:
840 divided by 86 is 9 with a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 3976.569
Deduct 774 from 840 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 10:
86 goes into 660 7 times with a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 3976.5697
Deduct 602 from 660 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 11:
86 goes into 580 6 times with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 3976.56976
Subtracting 516 from 580 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 12:
The number 86 fits into 640 7 times, leaving a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 3976.569767
If we take 602 away from 640, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 13:
If we divide 380 by 86, we get 4 and a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 3976.5697674
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 14:
360 divided by 86 is 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 3976.56976744
Subtracting 344 from 360 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 3976.56976744, and the remainder is 1.6e-08.
