We're dividing 169604 by 25 
Let's see how many times 25 fits into 169604.

Step 1:
If we divide 1 by 25, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 25

On to step 2:
25 can be fit into 16 0 times, resulting in a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 25

Moving on to step 3:
If we divide 169 by 25, we get 6 and a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 150 from 169, we get 19.
Fetch the next digit (6) from the dividend, attach it to 19 and continue: 196 / 25

Step 4:
The number 25 fits into 196 7 times, leaving a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
If we subtract 175 from 196, we get 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 25

Advancing to step 5:
When dividing 210 by 25, we get 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 678.0
Deduct 200 from 210 and we're left with 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 25

Advancing to step 6:
104 divided by 25 is 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 6784.0
The remainder is 4 after subtracting 100 from 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
When dividing 40 by 25, we get 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 6784.1
The remainder is 15 after subtracting 25 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 8:
150 divided by 25 is 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 6784.16
If we take 150 away from 150, 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: 6784.16
Subtracting 0 from 0 leaves us 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: 6784.16
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.

The final result is 6784.16 with a remainder of 0.0.
