35323631 ÷ 144 
The aim is to understand the frequency of 144 in 35323631.

Step 1:
144 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 144

On to step 2:
When dividing 35 by 144, we get 0 with a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Include the next digit (3) from the dividend after 35, then repeat: 353 / 144

Advancing to step 3:
144 can be fit into 353 2 times, resulting in a remainder of 65.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 288 from 353 leaves us with 65.
Append the next digit (2) from the dividend to 65 and continue with: 652 / 144

Moving on to step 4:
When dividing 652 by 144, we get 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtract 576 from 652 to get 76.
Fetch the next digit (3) from the dividend, attach it to 76 and continue: 763 / 144

On to step 5:
If we divide 763 by 144, we get 5 and a remainder of 43.
The next digit of our result is 5. 
Result so far: 245.0
If we take 720 away from 763, we end up with 43.
Include the next digit (6) from the dividend after 43, then repeat: 436 / 144

Going ahead to step 6:
144 can be fit into 436 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 2453.0
If we subtract 432 from 436, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 144

Let's proceed to step 7:
The number 144 fits into 43 0 times, leaving a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 24530.0
Deduct 0 from 43 and we're left with 43.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 144

Advancing to step 8:
144 can be fit into 431 2 times, resulting in a remainder of 143.
Put 2 as the next digit of the answer. 
Result so far: 245302.0
Subtracting 288 from 431 leaves us with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

Let's proceed to step 9:
If we divide 1430 by 144, we get 9 and a remainder of 134.
Record the quotient 9 as the next digit in the result. 
Result so far: 245302.9
Subtract 1296 from 1430 to get 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Going ahead to step 10:
If we divide 1340 by 144, we get 9 and a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 245302.99
Deduct 1296 from 1340 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.

The final outcome is 245302.99, with a leftover of 0.044.
