We divide 858475 by 25
The aim is to understand the frequency of 25 in 858475.

Going ahead to step 1:
25 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 25

Moving on to step 2:
25 can be fit into 85 3 times, resulting in a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 75 from 85, we get 10.
Take the next digit (8) from the dividend and append it to 10, then repeat: 108 / 25

Moving on to step 3:
If we divide 108 by 25, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 34.0
Deduct 100 from 108 and we're left with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 25

Going ahead to step 4:
The number 25 fits into 84 3 times, leaving a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 343.0
The remainder is 9 after subtracting 75 from 84.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 25

Advancing to step 5:
The number 25 fits into 97 3 times, leaving a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 3433.0
Subtract 75 from 97 to get 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 25

Moving on to step 6:
The number 25 fits into 225 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 34339.0
If we take 225 away from 225, 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 7:
0 divided by 25 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 34339.0
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.

Moving on to step 8:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 34339.0
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.

The quotient of the division is 34339.0, and the remainder is 0.0.
