We're dividing 893402 by 86 
The aim is to understand the frequency of 86 in 893402.

Let's proceed to step 1:
8 divided by 86 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 86

On to step 2:
When dividing 89 by 86, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 3 after subtracting 86 from 89.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 86

On to step 3:
33 divided by 86 is 0 with a remainder of 33.
The next digit of our result is 0. 
Result so far: 10.0
If we take 0 away from 33, we end up with 33.
Fetch the next digit (4) from the dividend, attach it to 33 and continue: 334 / 86

Advancing to step 4:
When dividing 334 by 86, we get 3 with a remainder of 76.
Write down 3 as next digit of the result. 
Result so far: 103.0
If we take 258 away from 334, we end up with 76.
Include the next digit (0) from the dividend after 76, then repeat: 760 / 86

Advancing to step 5:
When dividing 760 by 86, we get 8 with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 1038.0
The remainder is 72 after subtracting 688 from 760.
Grab the next digit (2) from the dividend, add it to 72, then carry on: 722 / 86

On to step 6:
722 divided by 86 is 8 with a remainder of 34.
Put 8 as the next digit of the answer. 
Result so far: 10388.0
If we subtract 688 from 722, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 7:
86 can be fit into 340 3 times, resulting in a remainder of 82.
The number 3 becomes the next digit in our result. 
Result so far: 10388.3
Subtracting 258 from 340 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 8:
When dividing 820 by 86, we get 9 with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 10388.39
Subtracting 774 from 820 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 9:
When dividing 460 by 86, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 10388.395
Subtracting 430 from 460 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
When dividing 300 by 86, we get 3 with a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 10388.3953
Deduct 258 from 300 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 11:
When dividing 420 by 86, we get 4 with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 10388.39534
Deduct 344 from 420 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 12:
86 goes into 760 8 times with a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 10388.395348
Subtracting 688 from 760 leaves us 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.

Moving on to step 13:
The number 86 fits into 720 8 times, leaving a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 10388.3953488
If we take 688 away from 720, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final result is 10388.3953488 with a remainder of 3.2e-07.
