Let's divide 42043253 by 144
The aim is to understand the frequency of 144 in 42043253.

Going ahead to step 1:
When dividing 4 by 144, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 144

Step 2:
144 can be fit into 42 0 times, resulting in a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 144

Let's proceed to step 3:
420 divided by 144 is 2 with a remainder of 132.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 288 from 420 to get 132.
Grab the next digit (4) from the dividend, add it to 132, then carry on: 1324 / 144

Going ahead to step 4:
1324 divided by 144 is 9 with a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Deduct 1296 from 1324 and we're left with 28.
Include the next digit (3) from the dividend after 28, then repeat: 283 / 144

Let's proceed to step 5:
If we divide 283 by 144, we get 1 and a remainder of 139.
The number 1 becomes the next digit in our result. 
Result so far: 291.0
Subtracting 144 from 283 leaves us with 139.
Fetch the next digit (2) from the dividend, attach it to 139 and continue: 1392 / 144

Let's proceed to step 6:
1392 divided by 144 is 9 with a remainder of 96.
The number 9 becomes the next digit in our result. 
Result so far: 2919.0
If we take 1296 away from 1392, we end up with 96.
Include the next digit (5) from the dividend after 96, then repeat: 965 / 144

Let's proceed to step 7:
965 divided by 144 is 6 with a remainder of 101.
Record the quotient 6 as the next digit in the result. 
Result so far: 29196.0
If we take 864 away from 965, we end up with 101.
Take the next digit (3) from the dividend and append it to 101, then repeat: 1013 / 144

Step 8:
144 goes into 1013 7 times with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 291967.0
If we take 1008 away from 1013, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 9:
144 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 291967.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
If we divide 500 by 144, we get 3 and a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 291967.03
Deduct 432 from 500 and we're left with 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 11:
680 divided by 144 is 4 with a remainder of 104.
Use 4 as the next digit of our solution. 
Result so far: 291967.034
Deduct 576 from 680 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 12:
When dividing 1040 by 144, we get 7 with a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 291967.0347
Subtract 1008 from 1040 to 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.

Moving on to step 13:
144 can be fit into 320 2 times, resulting in a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 291967.03472
The remainder is 32 after subtracting 288 from 320.
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 14:
The number 144 fits into 320 2 times, leaving a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 291967.034722
Subtract 288 from 320 to 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.

After the division, we end up with 291967.034722 and a remainder of 3.2e-06.
