We divide 138200 by 86
The aim is to understand the frequency of 86 in 138200.

Advancing to step 1:
The number 86 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 86

Step 2:
The number 86 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Grab the next digit (8) from the dividend, add it to 13, then carry on: 138 / 86

Advancing to step 3:
When dividing 138 by 86, we get 1 with a remainder of 52.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 86 away from 138, we end up with 52.
Bring next digit (2) of the dividend behind the 52 and repeat the process: 522 / 86

Moving on to step 4:
If we divide 522 by 86, we get 6 and a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 516 from 522, we get 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 86

Moving on to step 5:
When dividing 60 by 86, we get 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 160.0
Subtract 0 from 60 to get 60.
Append the next digit (0) from the dividend to 60 and continue with: 600 / 86

Going ahead to step 6:
86 goes into 600 6 times with a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 1606.0
The remainder is 84 after subtracting 516 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Let's proceed to step 7:
86 can be fit into 840 9 times, resulting in a remainder of 66.
The number 9 becomes the next digit in our result. 
Result so far: 1606.9
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.

Moving on to step 8:
660 divided by 86 is 7 with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 1606.97
If we take 602 away from 660, we end up 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.

Going ahead to step 9:
The number 86 fits into 580 6 times, leaving a remainder of 64.
The next digit of our result is 6. 
Result so far: 1606.976
Deduct 516 from 580 and we're left 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.

On to step 10:
When dividing 640 by 86, we get 7 with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 1606.9767
Deduct 602 from 640 and we're left 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.

On to step 11:
380 divided by 86 is 4 with a remainder of 36.
The next digit of our result is 4. 
Result so far: 1606.97674
Subtract 344 from 380 to 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.

Moving on to step 12:
The number 86 fits into 360 4 times, leaving a remainder of 16.
The next digit of our result is 4. 
Result so far: 1606.976744
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 1606.976744 and a remainder of 1.6e-06.
