17942043 ÷ 84 
The aim is to understand the frequency of 84 in 17942043.

Step 1:
1 divided by 84 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 84

Step 2:
84 goes into 17 0 times with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Take the next digit (9) from the dividend and append it to 17, then repeat: 179 / 84

Moving on to step 3:
If we divide 179 by 84, we get 2 and a remainder of 11.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 168 from 179 to get 11.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 84

Let's proceed to step 4:
84 can be fit into 114 1 times, resulting in a remainder of 30.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we take 84 away from 114, we end up with 30.
Include the next digit (2) from the dividend after 30, then repeat: 302 / 84

Step 5:
84 can be fit into 302 3 times, resulting in a remainder of 50.
Write down 3 as next digit of the result. 
Result so far: 213.0
The remainder is 50 after subtracting 252 from 302.
Include the next digit (0) from the dividend after 50, then repeat: 500 / 84

Moving on to step 6:
84 goes into 500 5 times with a remainder of 80.
The next digit of our result is 5. 
Result so far: 2135.0
If we take 420 away from 500, we end up with 80.
Bring next digit (4) of the dividend behind the 80 and repeat the process: 804 / 84

On to step 7:
804 divided by 84 is 9 with a remainder of 48.
The number 9 becomes the next digit in our result. 
Result so far: 21359.0
Subtract 756 from 804 to get 48.
Fetch the next digit (3) from the dividend, attach it to 48 and continue: 483 / 84

Going ahead to step 8:
483 divided by 84 is 5 with a remainder of 63.
Write down 5 as next digit of the result. 
Result so far: 213595.0
Subtract 420 from 483 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Let's proceed to step 9:
When dividing 630 by 84, we get 7 with a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 213595.7
Subtracting 588 from 630 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
When dividing 420 by 84, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 213595.75
Subtract 420 from 420 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
84 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 213595.75
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 12:
0 divided by 84 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 213595.75
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 213595.75 with a remaining 0.0.
