426942 divided by 25 
The aim is to understand the frequency of 25 in 426942.

Going ahead to step 1:
25 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 25

Going ahead to step 2:
42 divided by 25 is 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 17 after subtracting 25 from 42.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 25

On to step 3:
The number 25 fits into 176 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Deduct 175 from 176 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 25

Going ahead to step 4:
When dividing 19 by 25, we get 0 with a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 170.0
Subtract 0 from 19 to get 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 25

Step 5:
25 goes into 194 7 times with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 1707.0
Deduct 175 from 194 and we're left with 19.
Fetch the next digit (2) from the dividend, attach it to 19 and continue: 192 / 25

On to step 6:
25 goes into 192 7 times with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 17077.0
The remainder is 17 after subtracting 175 from 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
When dividing 170 by 25, we get 6 with a remainder of 20.
Write down 6 as next digit of the result. 
Result so far: 17077.6
If we take 150 away from 170, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
The number 25 fits into 200 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 17077.68
Deduct 200 from 200 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.

Step 9:
25 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 17077.68
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:
25 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 17077.68
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.

The quotient of the division is 17077.68, and the remainder is 0.0.
