422001 divided by 25 
The aim is to understand the frequency of 25 in 422001.

Advancing to step 1:
4 divided by 25 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 25

On to step 2:
42 divided by 25 is 1 with a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 25 from 42 to get 17.
Take the next digit (2) from the dividend and append it to 17, then repeat: 172 / 25

Advancing to step 3:
When dividing 172 by 25, we get 6 with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Subtract 150 from 172 to get 22.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 25

Moving on to step 4:
220 divided by 25 is 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 168.0
If we take 200 away from 220, we end up with 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 25

Step 5:
When dividing 200 by 25, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 1688.0
Subtracting 200 from 200 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 25

On to step 6:
25 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 16880.0
Subtract 0 from 1 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
The number 25 fits into 10 0 times, leaving a remainder of 10.
The next digit of our result is 0. 
Result so far: 16880.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
25 can be fit into 100 4 times, resulting in a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 16880.04
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.

Going ahead to step 9:
0 divided by 25 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 16880.04
If we subtract 0 from 0, we 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.

Moving on to step 10:
When dividing 0 by 25, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 16880.04
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 16880.04, and the remainder is 0.0.
