We divide 868100 by 84
The aim is to understand the frequency of 84 in 868100.

Advancing to step 1:
When dividing 8 by 84, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 84

Let's proceed to step 2:
84 goes into 86 1 times with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 84 from 86 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 84

Going ahead to step 3:
84 goes into 28 0 times with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 28 leaves us with 28.
Include the next digit (1) from the dividend after 28, then repeat: 281 / 84

Let's proceed to step 4:
If we divide 281 by 84, we get 3 and a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
If we subtract 252 from 281, we get 29.
Include the next digit (0) from the dividend after 29, then repeat: 290 / 84

On to step 5:
The number 84 fits into 290 3 times, leaving a remainder of 38.
The next digit of our result is 3. 
Result so far: 1033.0
Subtract 252 from 290 to get 38.
Append the next digit (0) from the dividend to 38 and continue with: 380 / 84

Advancing to step 6:
84 can be fit into 380 4 times, resulting in a remainder of 44.
Record the quotient 4 as the next digit in the result. 
Result so far: 10334.0
Subtracting 336 from 380 leaves us with 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 7:
84 goes into 440 5 times with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 10334.5
If we subtract 420 from 440, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
200 divided by 84 is 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 10334.52
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 9:
320 divided by 84 is 3 with a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 10334.523
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.

On to step 10:
The number 84 fits into 680 8 times, leaving a remainder of 8.
The next digit of our result is 8. 
Result so far: 10334.5238
The remainder is 8 after subtracting 672 from 680.
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 11:
84 can be fit into 80 0 times, resulting in a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 10334.5238
Deduct 0 from 80 and we're left 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 12:
800 divided by 84 is 9 with a remainder of 44.
Put 9 as the next digit of the answer. 
Result so far: 10334.523809
If we take 756 away from 800, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 13:
84 goes into 440 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 10334.5238095
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 14:
The number 84 fits into 200 2 times, leaving a remainder of 32.
The next digit of our result is 2. 
Result so far: 10334.52380952
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.

After the division, we end up with 10334.52380952 and a remainder of 3.2e-08.
