556451 divided by 86 
The aim is to understand the frequency of 86 in 556451.

Going ahead to step 1:
86 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 86

Step 2:
When dividing 55 by 86, we get 0 with a remainder of 55.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 55, we end up with 55.
Bring next digit (6) of the dividend behind the 55 and repeat the process: 556 / 86

Let's proceed to step 3:
86 can be fit into 556 6 times, resulting in a remainder of 40.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 516 from 556 leaves us with 40.
Bring next digit (4) of the dividend behind the 40 and repeat the process: 404 / 86

Moving on to step 4:
86 goes into 404 4 times with a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
Deduct 344 from 404 and we're left with 60.
Take the next digit (5) from the dividend and append it to 60, then repeat: 605 / 86

Step 5:
When dividing 605 by 86, we get 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 647.0
Subtracting 602 from 605 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 86

Step 6:
31 divided by 86 is 0 with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 6470.0
If we subtract 0 from 31, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to 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: 6470.3
If we subtract 258 from 310, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 8:
86 goes into 520 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 6470.36
Subtracting 516 from 520 leaves us with 4.
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.
The number 0 becomes the next digit in our result. 
Result so far: 6470.36
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
86 goes into 400 4 times with a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 6470.3604
If we subtract 344 from 400, we get 56.
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:
560 divided by 86 is 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 6470.36046
If we take 516 away from 560, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 12:
86 goes into 440 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 6470.360465
Subtract 430 from 440 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 13:
86 goes into 100 1 times with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 6470.3604651
Deduct 86 from 100 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 14:
The number 86 fits into 140 1 times, leaving a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 6470.36046511
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.

The final result is 6470.36046511 with a remainder of 5.4e-08.
