847740 divided by 86 
The aim is to understand the frequency of 86 in 847740.

Advancing to step 1:
If we divide 8 by 86, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 86

Advancing to step 2:
84 divided by 86 is 0 with a remainder of 84.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Grab the next digit (7) from the dividend, add it to 84, then carry on: 847 / 86

Step 3:
86 goes into 847 9 times with a remainder of 73.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 774 from 847 and we're left with 73.
Take the next digit (7) from the dividend and append it to 73, then repeat: 737 / 86

Going ahead to step 4:
737 divided by 86 is 8 with a remainder of 49.
The next digit of our result is 8. 
Result so far: 98.0
If we subtract 688 from 737, we get 49.
Grab the next digit (4) from the dividend, add it to 49, then carry on: 494 / 86

Moving on to step 5:
86 goes into 494 5 times with a remainder of 64.
Write down 5 as next digit of the result. 
Result so far: 985.0
If we take 430 away from 494, we end up with 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 86

On to step 6:
If we divide 640 by 86, we get 7 and a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 9857.0
Subtract 602 from 640 to get 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 7:
380 divided by 86 is 4 with a remainder of 36.
The next digit of our result is 4. 
Result so far: 9857.4
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.

Going ahead to step 8:
If we divide 360 by 86, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 9857.44
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.

The final result is 9857.44 with a remainder of 0.016.
