33984323 ÷ 642 
The aim is to understand the frequency of 642 in 33984323.

On to step 1:
When dividing 3 by 642, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 642

Moving on to step 2:
642 goes into 33 0 times with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 33, we get 33.
Append the next digit (9) from the dividend to 33 and continue with: 339 / 642

On to step 3:
When dividing 339 by 642, we get 0 with a remainder of 339.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 339 leaves us with 339.
Fetch the next digit (8) from the dividend, attach it to 339 and continue: 3398 / 642

Let's proceed to step 4:
3398 divided by 642 is 5 with a remainder of 188.
The next digit of our result is 5. 
Result so far: 5.0
If we take 3210 away from 3398, we end up with 188.
Take the next digit (4) from the dividend and append it to 188, then repeat: 1884 / 642

Going ahead to step 5:
When dividing 1884 by 642, we get 2 with a remainder of 600.
Write down 2 as next digit of the result. 
Result so far: 52.0
If we take 1284 away from 1884, we end up with 600.
Grab the next digit (3) from the dividend, add it to 600, then carry on: 6003 / 642

Advancing to step 6:
642 can be fit into 6003 9 times, resulting in a remainder of 225.
The number 9 becomes the next digit in our result. 
Result so far: 529.0
If we take 5778 away from 6003, we end up with 225.
Fetch the next digit (2) from the dividend, attach it to 225 and continue: 2252 / 642

Going ahead to step 7:
642 can be fit into 2252 3 times, resulting in a remainder of 326.
The number 3 becomes the next digit in our result. 
Result so far: 5293.0
The remainder is 326 after subtracting 1926 from 2252.
Fetch the next digit (3) from the dividend, attach it to 326 and continue: 3263 / 642

Going ahead to step 8:
When dividing 3263 by 642, we get 5 with a remainder of 53.
The number 5 becomes the next digit in our result. 
Result so far: 52935.0
Deduct 3210 from 3263 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 9:
642 can be fit into 530 0 times, resulting in a remainder of 530.
Put 0 as the next digit of the answer. 
Result so far: 52935.0
Subtract 0 from 530 to get 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

On to step 10:
642 goes into 5300 8 times with a remainder of 164.
Record the quotient 8 as the next digit in the result. 
Result so far: 52935.08
Subtract 5136 from 5300 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 11:
When dividing 1640 by 642, we get 2 with a remainder of 356.
The number 2 becomes the next digit in our result. 
Result so far: 52935.082
Subtract 1284 from 1640 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Let's proceed to step 12:
If we divide 3560 by 642, we get 5 and a remainder of 350.
The next digit of our result is 5. 
Result so far: 52935.0825
The remainder is 350 after subtracting 3210 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

Step 13:
642 goes into 3500 5 times with a remainder of 290.
Write down 5 as next digit of the result. 
Result so far: 52935.08255
The remainder is 290 after subtracting 3210 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

The final outcome is 52935.08255, with a leftover of 0.00029.
