316324 divided by 86 
The aim is to understand the frequency of 86 in 316324.

Step 1:
When dividing 3 by 86, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 86

On to step 2:
If we divide 31 by 86, we get 0 and a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Take the next digit (6) from the dividend and append it to 31, then repeat: 316 / 86

Going ahead to step 3:
86 can be fit into 316 3 times, resulting in a remainder of 58.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 58 after subtracting 258 from 316.
Take the next digit (3) from the dividend and append it to 58, then repeat: 583 / 86

Advancing to step 4:
86 goes into 583 6 times with a remainder of 67.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtract 516 from 583 to get 67.
Append the next digit (2) from the dividend to 67 and continue with: 672 / 86

Step 5:
86 goes into 672 7 times with a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 367.0
Subtract 602 from 672 to get 70.
Fetch the next digit (4) from the dividend, attach it to 70 and continue: 704 / 86

Let's proceed to step 6:
86 goes into 704 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 3678.0
The remainder is 16 after subtracting 688 from 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
86 goes into 160 1 times with a remainder of 74.
The next digit of our result is 1. 
Result so far: 3678.1
The remainder is 74 after subtracting 86 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 8:
If we divide 740 by 86, we get 8 and a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 3678.18
The remainder is 52 after subtracting 688 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 9:
When dividing 520 by 86, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 3678.186
If we subtract 516 from 520, we get 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 10:
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: 3678.186
Deduct 0 from 40 and we're left 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.

Moving on to step 11:
The number 86 fits into 400 4 times, leaving a remainder of 56.
The next digit of our result is 4. 
Result so far: 3678.18604
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.

Step 12:
86 goes into 560 6 times with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 3678.186046
If we subtract 516 from 560, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 13:
The number 86 fits into 440 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 3678.1860465
Deduct 430 from 440 and we're left 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.

Advancing to step 14:
If we divide 100 by 86, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 3678.18604651
If we take 86 away from 100, we end up 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.

The quotient of the division is 3678.18604651, and the remainder is 1.4e-08.
