We're dividing 842966 by 84 
The aim is to understand the frequency of 84 in 842966.

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.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 84

Let's proceed to step 2:
If we divide 84 by 84, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 84 from 84 to get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 84

On to step 3:
84 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 84

On to step 4:
29 divided by 84 is 0 with a remainder of 29.
Write down 0 as next digit of the result. 
Result so far: 100.0
Deduct 0 from 29 and we're left with 29.
Append the next digit (6) from the dividend to 29 and continue with: 296 / 84

Going ahead to step 5:
The number 84 fits into 296 3 times, leaving a remainder of 44.
The number 3 becomes the next digit in our result. 
Result so far: 1003.0
Deduct 252 from 296 and we're left with 44.
Take the next digit (6) from the dividend and append it to 44, then repeat: 446 / 84

On to step 6:
84 goes into 446 5 times with a remainder of 26.
Record the quotient 5 as the next digit in the result. 
Result so far: 10035.0
Subtract 420 from 446 to 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.

Let's proceed to step 7:
84 goes into 260 3 times with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 10035.3
If we subtract 252 from 260, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
84 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 10035.3
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 9:
84 goes into 800 9 times with a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 10035.309
Deduct 756 from 800 and we're left 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 10:
84 goes into 440 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 10035.3095
The remainder is 20 after subtracting 420 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
84 can be fit into 200 2 times, resulting in a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 10035.30952
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 12:
If we divide 320 by 84, we get 3 and a remainder of 68.
Use 3 as the next digit of our solution. 
Result so far: 10035.309523
If we subtract 252 from 320, we get 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 13:
The number 84 fits into 680 8 times, leaving a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 10035.3095238
Deduct 672 from 680 and we're left 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.

Step 14:
If we divide 80 by 84, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 10035.3095238
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.

The quotient of the division is 10035.3095238, and the remainder is 8e-08.
