Let's divide 343343 by 86
The aim is to understand the frequency of 86 in 343343.

Step 1:
The number 86 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 86

Going ahead to step 2:
86 goes into 34 0 times with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Fetch the next digit (3) from the dividend, attach it to 34 and continue: 343 / 86

Advancing to step 3:
86 can be fit into 343 3 times, resulting in a remainder of 85.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 85 after subtracting 258 from 343.
Grab the next digit (3) from the dividend, add it to 85, then carry on: 853 / 86

Moving on to step 4:
86 goes into 853 9 times with a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 39.0
The remainder is 79 after subtracting 774 from 853.
Grab the next digit (4) from the dividend, add it to 79, then carry on: 794 / 86

Going ahead to step 5:
794 divided by 86 is 9 with a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 399.0
Deduct 774 from 794 and we're left with 20.
Grab the next digit (3) from the dividend, add it to 20, then carry on: 203 / 86

Step 6:
203 divided by 86 is 2 with a remainder of 31.
The number 2 becomes the next digit in our result. 
Result so far: 3992.0
Deduct 172 from 203 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 7:
If we divide 310 by 86, we get 3 and a remainder of 52.
The number 3 becomes the next digit in our result. 
Result so far: 3992.3
If we take 258 away from 310, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 8:
86 can be fit into 520 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 3992.36
The remainder is 4 after subtracting 516 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
86 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 3992.36
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 10:
86 goes into 400 4 times with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 3992.3604
The remainder is 56 after subtracting 344 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 11:
If we divide 560 by 86, we get 6 and a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 3992.36046
The remainder is 44 after subtracting 516 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 12:
86 goes into 440 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 3992.360465
If we take 430 away from 440, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
When dividing 100 by 86, we get 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 3992.3604651
If we subtract 86 from 100, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 14:
The number 86 fits into 140 1 times, leaving a remainder of 54.
Record the quotient 1 as the next digit in the result. 
Result so far: 3992.36046511
If we subtract 86 from 140, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

In conclusion, the division gives 3992.36046511 with a balance of 5.4e-08.
