We're dividing 58620 by 86 
The aim is to understand the frequency of 86 in 58620.

Going ahead to step 1:
The number 86 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 86

On to step 2:
58 divided by 86 is 0 with a remainder of 58.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 58 and we're left with 58.
Bring next digit (6) of the dividend behind the 58 and repeat the process: 586 / 86

Advancing to step 3:
86 can be fit into 586 6 times, resulting in a remainder of 70.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 516 from 586, we get 70.
Bring next digit (2) of the dividend behind the 70 and repeat the process: 702 / 86

On to step 4:
The number 86 fits into 702 8 times, leaving a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
Subtract 688 from 702 to get 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 86

Step 5:
140 divided by 86 is 1 with a remainder of 54.
The number 1 becomes the next digit in our result. 
Result so far: 681.0
Subtract 86 from 140 to 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.

Advancing to step 6:
540 divided by 86 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 681.6
Deduct 516 from 540 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
When dividing 240 by 86, we get 2 with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 681.62
If we take 172 away from 240, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 8:
When dividing 680 by 86, we get 7 with a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 681.627
If we take 602 away from 680, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 9:
86 goes into 780 9 times with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 681.6279
Subtracting 774 from 780 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
60 divided by 86 is 0 with a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 681.6279
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
86 can be fit into 600 6 times, resulting in a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 681.627906
The remainder is 84 after subtracting 516 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 12:
86 goes into 840 9 times with a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 681.6279069
The remainder is 66 after subtracting 774 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 13:
86 can be fit into 660 7 times, resulting in a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 681.62790697
Subtracting 602 from 660 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final result is 681.62790697 with a remainder of 5.8e-08.
