We look at the division of 720414 by 25 
The aim is to understand the frequency of 25 in 720414.

Moving on to step 1:
The number 25 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 25

Going ahead to step 2:
72 divided by 25 is 2 with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 50 from 72 leaves us with 22.
Append the next digit (0) from the dividend to 22 and continue with: 220 / 25

Advancing to step 3:
If we divide 220 by 25, we get 8 and a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtract 200 from 220 to get 20.
Bring next digit (4) of the dividend behind the 20 and repeat the process: 204 / 25

Advancing to step 4:
204 divided by 25 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 288.0
The remainder is 4 after subtracting 200 from 204.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 25

Moving on to step 5:
41 divided by 25 is 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 2881.0
If we take 25 away from 41, we end up with 16.
Grab the next digit (4) from the dividend, add it to 16, then carry on: 164 / 25

Step 6:
When dividing 164 by 25, we get 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 28816.0
The remainder is 14 after subtracting 150 from 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 7:
If we divide 140 by 25, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 28816.5
Subtracting 125 from 140 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
The number 25 fits into 150 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 28816.56
Subtract 150 from 150 to get 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 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 28816.56
Subtracting 0 from 0 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.

Advancing to step 10:
When dividing 0 by 25, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 28816.56
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.

The final result is 28816.56 with a remainder of 0.0.
