We're dividing 30257250 by 144 
The aim is to understand the frequency of 144 in 30257250.

Advancing to step 1:
144 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 144

Advancing to step 2:
The number 144 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Fetch the next digit (2) from the dividend, attach it to 30 and continue: 302 / 144

Going ahead to step 3:
When dividing 302 by 144, we get 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 288 from 302 leaves us with 14.
Bring next digit (5) of the dividend behind the 14 and repeat the process: 145 / 144

Moving on to step 4:
144 goes into 145 1 times with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we take 144 away from 145, we end up with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 144

Advancing to step 5:
When dividing 17 by 144, we get 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 210.0
Deduct 0 from 17 and we're left with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 144

Moving on to step 6:
144 goes into 172 1 times with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 2101.0
If we take 144 away from 172, we end up with 28.
Append the next digit (5) from the dividend to 28 and continue with: 285 / 144

On to step 7:
144 goes into 285 1 times with a remainder of 141.
The number 1 becomes the next digit in our result. 
Result so far: 21011.0
If we subtract 144 from 285, we get 141.
Include the next digit (0) from the dividend after 141, then repeat: 1410 / 144

Let's proceed to step 8:
144 can be fit into 1410 9 times, resulting in a remainder of 114.
The number 9 becomes the next digit in our result. 
Result so far: 210119.0
The remainder is 114 after subtracting 1296 from 1410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

On to step 9:
If we divide 1140 by 144, we get 7 and a remainder of 132.
The number 7 becomes the next digit in our result. 
Result so far: 210119.7
Subtract 1008 from 1140 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Advancing to step 10:
144 goes into 1320 9 times with a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 210119.79
If we subtract 1296 from 1320, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
The number 144 fits into 240 1 times, leaving a remainder of 96.
Write down 1 as next digit of the result. 
Result so far: 210119.791
If we subtract 144 from 240, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 12:
If we divide 960 by 144, we get 6 and a remainder of 96.
Use 6 as the next digit of our solution. 
Result so far: 210119.7916
The remainder is 96 after subtracting 864 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 13:
If we divide 960 by 144, we get 6 and a remainder of 96.
Write down 6 as next digit of the result. 
Result so far: 210119.79166
Deduct 864 from 960 and we're left with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

After the division, we end up with 210119.79166 and a remainder of 9.6e-05.
