Let's divide 937308 by 86
The aim is to understand the frequency of 86 in 937308.

Step 1:
When dividing 9 by 86, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 86

Going ahead to step 2:
86 goes into 93 1 times with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 86 from 93, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 86

Going ahead to step 3:
The number 86 fits into 77 0 times, leaving a remainder of 77.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 77 to get 77.
Include the next digit (3) from the dividend after 77, then repeat: 773 / 86

Going ahead to step 4:
86 can be fit into 773 8 times, resulting in a remainder of 85.
Record the quotient 8 as the next digit in the result. 
Result so far: 108.0
Subtracting 688 from 773 leaves us with 85.
Include the next digit (0) from the dividend after 85, then repeat: 850 / 86

Step 5:
86 goes into 850 9 times with a remainder of 76.
Record the quotient 9 as the next digit in the result. 
Result so far: 1089.0
The remainder is 76 after subtracting 774 from 850.
Fetch the next digit (8) from the dividend, attach it to 76 and continue: 768 / 86

Going ahead to step 6:
When dividing 768 by 86, we get 8 with a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 10898.0
If we take 688 away from 768, we end up 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.

Step 7:
800 divided by 86 is 9 with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 10898.9
If we subtract 774 from 800, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 8:
If we divide 260 by 86, we get 3 and a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 10898.93
If we subtract 258 from 260, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
86 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 10898.93
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.

On to step 10:
86 goes into 200 2 times with a remainder of 28.
Write down 2 as next digit of the result. 
Result so far: 10898.9302
Deduct 172 from 200 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
When dividing 280 by 86, we get 3 with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 10898.93023
Deduct 258 from 280 and we're left 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.

Going ahead to step 12:
86 can be fit into 220 2 times, resulting in a remainder of 48.
The next digit of our result is 2. 
Result so far: 10898.930232
If we take 172 away from 220, we end up 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.

Going ahead to step 13:
86 goes into 480 5 times with a remainder of 50.
The next digit of our result is 5. 
Result so far: 10898.9302325
If we take 430 away from 480, we end up 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.

Moving on to step 14:
500 divided by 86 is 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 10898.93023255
Subtract 430 from 500 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.

The final result is 10898.93023255 with a remainder of 7e-08.
