We look at the division of 868715 by 84 
The aim is to understand the frequency of 84 in 868715.

Going ahead to step 1:
The number 84 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 84

Step 2:
84 goes into 86 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 84 from 86 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 84

Advancing to step 3:
The number 84 fits into 28 0 times, leaving a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we take 0 away from 28, we end up with 28.
Bring next digit (7) of the dividend behind the 28 and repeat the process: 287 / 84

On to step 4:
84 goes into 287 3 times with a remainder of 35.
The next digit of our result is 3. 
Result so far: 103.0
Subtract 252 from 287 to get 35.
Bring next digit (1) of the dividend behind the 35 and repeat the process: 351 / 84

Let's proceed to step 5:
The number 84 fits into 351 4 times, leaving a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 1034.0
If we subtract 336 from 351, we get 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 84

On to step 6:
If we divide 155 by 84, we get 1 and a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 10341.0
Deduct 84 from 155 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 7:
The number 84 fits into 710 8 times, leaving a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 10341.8
Subtracting 672 from 710 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 8:
When dividing 380 by 84, we get 4 with a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 10341.84
The remainder is 44 after subtracting 336 from 380.
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 9:
440 divided by 84 is 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 10341.845
Deduct 420 from 440 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
If we divide 200 by 84, we get 2 and a remainder of 32.
The next digit of our result is 2. 
Result so far: 10341.8452
Subtracting 168 from 200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 11:
84 can be fit into 320 3 times, resulting in a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 10341.84523
Subtracting 252 from 320 leaves us 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 12:
If we divide 680 by 84, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 10341.845238
If we take 672 away from 680, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
The number 84 fits into 80 0 times, leaving a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 10341.845238
If we take 0 away from 80, 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.

Let's proceed to step 14:
84 goes into 800 9 times with a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 10341.84523809
The remainder is 44 after subtracting 756 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

The quotient of the division is 10341.84523809, and the remainder is 4.4e-08.
