144212 ÷ 25 
The aim is to understand the frequency of 25 in 144212.

Advancing to step 1:
The number 25 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 25

On to step 2:
When dividing 14 by 25, we get 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 14, we end up with 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 25

Let's proceed to step 3:
25 can be fit into 144 5 times, resulting in a remainder of 19.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 125 from 144, we get 19.
Append the next digit (2) from the dividend to 19 and continue with: 192 / 25

Moving on to step 4:
If we divide 192 by 25, we get 7 and a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
Subtracting 175 from 192 leaves us with 17.
Bring next digit (1) of the dividend behind the 17 and repeat the process: 171 / 25

Going ahead to step 5:
If we divide 171 by 25, we get 6 and a remainder of 21.
The next digit of our result is 6. 
Result so far: 576.0
The remainder is 21 after subtracting 150 from 171.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 25

Advancing to step 6:
212 divided by 25 is 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 5768.0
Deduct 200 from 212 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
120 divided by 25 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 5768.4
If we take 100 away from 120, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
When dividing 200 by 25, we get 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 5768.48
Subtracting 200 from 200 leaves us 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.

Going ahead to step 9:
25 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 5768.48
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.

Step 10:
0 divided by 25 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 5768.48
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 5768.48, with a leftover of 0.0.
