We look at the division of 393802 by 86 
The aim is to understand the frequency of 86 in 393802.

Moving on to step 1:
86 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 86

Advancing to step 2:
If we divide 39 by 86, we get 0 and a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 86

Going ahead to step 3:
393 divided by 86 is 4 with a remainder of 49.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 344 from 393 to get 49.
Grab the next digit (8) from the dividend, add it to 49, then carry on: 498 / 86

On to step 4:
If we divide 498 by 86, we get 5 and a remainder of 68.
The next digit of our result is 5. 
Result so far: 45.0
If we take 430 away from 498, we end up with 68.
Include the next digit (0) from the dividend after 68, then repeat: 680 / 86

Step 5:
The number 86 fits into 680 7 times, leaving a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 457.0
Subtract 602 from 680 to get 78.
Include the next digit (2) from the dividend after 78, then repeat: 782 / 86

Moving on to step 6:
782 divided by 86 is 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 4579.0
If we subtract 774 from 782, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
The number 86 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 4579.0
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 8:
800 divided by 86 is 9 with a remainder of 26.
Use 9 as the next digit of our solution. 
Result so far: 4579.09
Subtracting 774 from 800 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
86 goes into 260 3 times with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 4579.093
Deduct 258 from 260 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
86 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 4579.093
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
The number 86 fits into 200 2 times, leaving a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 4579.09302
If we subtract 172 from 200, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 12:
86 can be fit into 280 3 times, resulting in a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 4579.093023
Subtracting 258 from 280 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 13:
The number 86 fits into 220 2 times, leaving a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 4579.0930232
Deduct 172 from 220 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 14:
If we divide 480 by 86, we get 5 and a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 4579.09302325
Subtracting 430 from 480 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 4579.09302325 with a balance of 5e-08.
