We're dividing 156673 by 25 
The aim is to understand the frequency of 25 in 156673.

On to step 1:
The number 25 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 25

Moving on to step 2:
If we divide 15 by 25, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Include the next digit (6) from the dividend after 15, then repeat: 156 / 25

Let's proceed to step 3:
If we divide 156 by 25, we get 6 and a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 150 from 156, we get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 25

Advancing to step 4:
If we divide 66 by 25, we get 2 and a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 62.0
Subtract 50 from 66 to get 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 25

Let's proceed to step 5:
167 divided by 25 is 6 with a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 626.0
The remainder is 17 after subtracting 150 from 167.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 25

Let's proceed to step 6:
If we divide 173 by 25, we get 6 and a remainder of 23.
Put 6 as the next digit of the answer. 
Result so far: 6266.0
Subtract 150 from 173 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
The number 25 fits into 230 9 times, leaving a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 6266.9
The remainder is 5 after subtracting 225 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
The number 25 fits into 50 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 6266.92
Subtract 50 from 50 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.

Let's proceed to step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 6266.92
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.

On to step 10:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 6266.92
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 result is 6266.92 with a remainder of 0.0.
