We divide 836485 by 25
The aim is to understand the frequency of 25 in 836485.

Advancing to step 1:
When dividing 8 by 25, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 25

Step 2:
The number 25 fits into 83 3 times, leaving a remainder of 8.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 75 from 83 and we're left with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 25

On to step 3:
If we divide 86 by 25, we get 3 and a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Deduct 75 from 86 and we're left with 11.
Fetch the next digit (4) from the dividend, attach it to 11 and continue: 114 / 25

Let's proceed to step 4:
The number 25 fits into 114 4 times, leaving a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 334.0
Subtracting 100 from 114 leaves us with 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 25

On to step 5:
148 divided by 25 is 5 with a remainder of 23.
Put 5 as the next digit of the answer. 
Result so far: 3345.0
Subtract 125 from 148 to get 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 25

Advancing to step 6:
The number 25 fits into 235 9 times, leaving a remainder of 10.
Use 9 as the next digit of our solution. 
Result so far: 33459.0
Subtracting 225 from 235 leaves us 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:
When dividing 100 by 25, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 33459.4
Subtract 100 from 100 to 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.

Going ahead to step 8:
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: 33459.4
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.

Let's proceed to step 9:
The number 25 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 33459.4
Subtract 0 from 0 to 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 final outcome is 33459.4, with a leftover of 0.0.
