Let's divide 670899 by 25
The aim is to understand the frequency of 25 in 670899.

Moving on to step 1:
25 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 25

Let's proceed to step 2:
The number 25 fits into 67 2 times, leaving a remainder of 17.
The next digit of our result is 2. 
Result so far: 2.0
If we take 50 away from 67, we end up with 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 25

Moving on to step 3:
25 can be fit into 170 6 times, resulting in a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
Subtracting 150 from 170 leaves us with 20.
Bring next digit (8) of the dividend behind the 20 and repeat the process: 208 / 25

Let's proceed to step 4:
If we divide 208 by 25, we get 8 and a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 268.0
Subtracting 200 from 208 leaves us with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 25

On to step 5:
The number 25 fits into 89 3 times, leaving a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 2683.0
If we subtract 75 from 89, we get 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 25

On to step 6:
When dividing 149 by 25, we get 5 with a remainder of 24.
Record the quotient 5 as the next digit in the result. 
Result so far: 26835.0
Deduct 125 from 149 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
25 can be fit into 240 9 times, resulting in a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 26835.9
The remainder is 15 after subtracting 225 from 240.
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:
25 goes into 150 6 times with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 26835.96
Deduct 150 from 150 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.

Moving on 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: 26835.96
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 10:
0 divided by 25 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 26835.96
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 26835.96 with a remaining 0.0.
