Let's divide 667860 by 25
The aim is to understand the frequency of 25 in 667860.

On to step 1:
When dividing 6 by 25, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 25

Moving on to step 2:
25 can be fit into 66 2 times, resulting in a remainder of 16.
The next digit of our result is 2. 
Result so far: 2.0
If we take 50 away from 66, we end up with 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 25

Let's proceed to step 3:
25 goes into 167 6 times with a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 26.0
If we take 150 away from 167, we end up with 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 25

Going ahead to step 4:
When dividing 178 by 25, we get 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 267.0
If we subtract 175 from 178, we get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 25

Let's proceed to step 5:
25 can be fit into 36 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 2671.0
If we take 25 away from 36, we end up with 11.
Grab the next digit (0) from the dividend, add it to 11, then carry on: 110 / 25

On to step 6:
25 can be fit into 110 4 times, resulting in a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 26714.0
If we take 100 away from 110, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
100 divided by 25 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 26714.4
If we take 100 away from 100, 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 8:
0 divided by 25 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 26714.4
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.

On to step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 26714.4
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.

Our division results in 26714.4 with a remaining 0.0.
