761338 divided by 86 
The aim is to understand the frequency of 86 in 761338.

Step 1:
86 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 86

On to step 2:
The number 86 fits into 76 0 times, leaving a remainder of 76.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 76 after subtracting 0 from 76.
Include the next digit (1) from the dividend after 76, then repeat: 761 / 86

Let's proceed to step 3:
86 goes into 761 8 times with a remainder of 73.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 688 from 761, we get 73.
Include the next digit (3) from the dividend after 73, then repeat: 733 / 86

Advancing to step 4:
86 goes into 733 8 times with a remainder of 45.
Use 8 as the next digit of our solution. 
Result so far: 88.0
If we subtract 688 from 733, we get 45.
Grab the next digit (3) from the dividend, add it to 45, then carry on: 453 / 86

Step 5:
453 divided by 86 is 5 with a remainder of 23.
The next digit of our result is 5. 
Result so far: 885.0
Deduct 430 from 453 and we're left with 23.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 86

Moving on to step 6:
The number 86 fits into 238 2 times, leaving a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 8852.0
If we take 172 away from 238, we end up 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.

Going ahead to step 7:
86 goes into 660 7 times with a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 8852.7
If we subtract 602 from 660, we get 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 8:
580 divided by 86 is 6 with a remainder of 64.
The next digit of our result is 6. 
Result so far: 8852.76
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.

Going ahead to step 9:
When dividing 640 by 86, we get 7 with a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 8852.767
Subtracting 602 from 640 leaves us 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.

Going ahead to step 10:
If we divide 380 by 86, we get 4 and a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 8852.7674
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.

Step 11:
360 divided by 86 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 8852.76744
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 final result is 8852.76744 with a remainder of 1.6e-05.
