We divide 87965 by 86
The aim is to understand the frequency of 86 in 87965.

Let's proceed to step 1:
86 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 86

Advancing to step 2:
87 divided by 86 is 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 1 after subtracting 86 from 87.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 86

Let's proceed to step 3:
19 divided by 86 is 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 19 after subtracting 0 from 19.
Include the next digit (6) from the dividend after 19, then repeat: 196 / 86

Advancing to step 4:
86 goes into 196 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 102.0
If we take 172 away from 196, we end up with 24.
Grab the next digit (5) from the dividend, add it to 24, then carry on: 245 / 86

Going ahead to step 5:
The number 86 fits into 245 2 times, leaving a remainder of 73.
The number 2 becomes the next digit in our result. 
Result so far: 1022.0
The remainder is 73 after subtracting 172 from 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 6:
If we divide 730 by 86, we get 8 and a remainder of 42.
The next digit of our result is 8. 
Result so far: 1022.8
Deduct 688 from 730 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 7:
If we divide 420 by 86, we get 4 and a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 1022.84
Subtract 344 from 420 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 8:
When dividing 760 by 86, we get 8 with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 1022.848
If we take 688 away from 760, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 9:
720 divided by 86 is 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 1022.8488
If we subtract 688 from 720, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Our division results in 1022.8488 with a remaining 0.00032.
