We divide 155630 by 25
The aim is to understand the frequency of 25 in 155630.

Let's proceed to step 1:
1 divided by 25 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 25

Let's proceed to step 2:
The number 25 fits into 15 0 times, leaving a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Append the next digit (5) from the dividend to 15 and continue with: 155 / 25

On to step 3:
The number 25 fits into 155 6 times, leaving a remainder of 5.
The next digit of our result is 6. 
Result so far: 6.0
If we take 150 away from 155, we end up with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 25

Step 4:
56 divided by 25 is 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 62.0
If we subtract 50 from 56, we get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 25

Step 5:
25 can be fit into 63 2 times, resulting in a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 622.0
Subtract 50 from 63 to get 13.
Bring next digit (0) of the dividend behind the 13 and repeat the process: 130 / 25

Step 6:
25 goes into 130 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 6225.0
If we take 125 away from 130, 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.

On to step 7:
The number 25 fits into 50 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 6225.2
Deduct 50 from 50 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.

Going ahead to step 8:
25 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 6225.2
If we take 0 away from 0, we end up 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.

Let's proceed to step 9:
When dividing 0 by 25, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 6225.2
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 6225.2 with a remainder of 0.0.
