We look at the division of 33789903 by 84 
The aim is to understand the frequency of 84 in 33789903.

On to step 1:
84 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 84

Moving on to step 2:
When dividing 33 by 84, we get 0 with a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 33 to get 33.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 84

Let's proceed to step 3:
84 can be fit into 337 4 times, resulting in a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 336 from 337 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 84

On to step 4:
84 goes into 18 0 times with a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtracting 0 from 18 leaves us with 18.
Append the next digit (9) from the dividend to 18 and continue with: 189 / 84

Going ahead to step 5:
84 goes into 189 2 times with a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 402.0
The remainder is 21 after subtracting 168 from 189.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 84

On to step 6:
219 divided by 84 is 2 with a remainder of 51.
The number 2 becomes the next digit in our result. 
Result so far: 4022.0
If we subtract 168 from 219, we get 51.
Grab the next digit (0) from the dividend, add it to 51, then carry on: 510 / 84

On to step 7:
If we divide 510 by 84, we get 6 and a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 40226.0
If we subtract 504 from 510, we get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 84

Let's proceed to step 8:
If we divide 63 by 84, we get 0 and a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 402260.0
Subtracting 0 from 63 leaves us with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 9:
84 can be fit into 630 7 times, resulting in a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 402260.7
The remainder is 42 after subtracting 588 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
If we divide 420 by 84, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 402260.75
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.

Moving on to step 11:
84 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 402260.75
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.

Moving on to step 12:
84 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 402260.75
Deduct 0 from 0 and we're left 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.

After the division, we end up with 402260.75 and a remainder of 0.0.
