We're dividing 599169 by 86 
The aim is to understand the frequency of 86 in 599169.

Advancing to step 1:
The number 86 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 86

Let's proceed to step 2:
If we divide 59 by 86, we get 0 and a remainder of 59.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 59, we end up with 59.
Bring next digit (9) of the dividend behind the 59 and repeat the process: 599 / 86

Going ahead to step 3:
599 divided by 86 is 6 with a remainder of 83.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 516 from 599, we get 83.
Bring next digit (1) of the dividend behind the 83 and repeat the process: 831 / 86

Going ahead to step 4:
When dividing 831 by 86, we get 9 with a remainder of 57.
The next digit of our result is 9. 
Result so far: 69.0
Subtract 774 from 831 to get 57.
Fetch the next digit (6) from the dividend, attach it to 57 and continue: 576 / 86

Advancing to step 5:
When dividing 576 by 86, we get 6 with a remainder of 60.
The next digit of our result is 6. 
Result so far: 696.0
If we subtract 516 from 576, we get 60.
Bring next digit (9) of the dividend behind the 60 and repeat the process: 609 / 86

On to step 6:
The number 86 fits into 609 7 times, leaving a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 6967.0
Deduct 602 from 609 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
When dividing 70 by 86, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 6967.0
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
700 divided by 86 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 6967.08
If we subtract 688 from 700, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
The number 86 fits into 120 1 times, leaving a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 6967.081
If we take 86 away from 120, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
86 can be fit into 340 3 times, resulting in a remainder of 82.
Put 3 as the next digit of the answer. 
Result so far: 6967.0813
If we take 258 away from 340, we end up 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.

Moving on to step 11:
86 can be fit into 820 9 times, resulting in a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 6967.08139
If we take 774 away from 820, we end up 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.

On to step 12:
86 can be fit into 460 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 6967.081395
Deduct 430 from 460 and we're left 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.

Advancing to step 13:
86 goes into 300 3 times with a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 6967.0813953
Subtract 258 from 300 to get 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 14:
The number 86 fits into 420 4 times, leaving a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 6967.08139534
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.

The final result is 6967.08139534 with a remainder of 7.6e-08.
