We look at the division of 16890976 by 25 
Let's see how many times 25 fits into 16890976.

Let's proceed to step 1:
25 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 25

Moving on to step 2:
The number 25 fits into 16 0 times, leaving a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 25

Advancing to step 3:
168 divided by 25 is 6 with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 150 from 168 to get 18.
Grab the next digit (9) from the dividend, add it to 18, then carry on: 189 / 25

Advancing to step 4:
25 can be fit into 189 7 times, resulting in a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 67.0
Subtract 175 from 189 to get 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 25

Advancing to step 5:
The number 25 fits into 140 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 675.0
The remainder is 15 after subtracting 125 from 140.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 25

Step 6:
159 divided by 25 is 6 with a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 6756.0
Subtracting 150 from 159 leaves us with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 25

On to step 7:
The number 25 fits into 97 3 times, leaving a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 67563.0
If we subtract 75 from 97, we get 22.
Fetch the next digit (6) from the dividend, attach it to 22 and continue: 226 / 25

Advancing to step 8:
If we divide 226 by 25, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 675639.0
If we take 225 away from 226, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
When dividing 10 by 25, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 675639.0
If we take 0 away from 10, we end up 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.

Step 10:
25 goes into 100 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 675639.04
Deduct 100 from 100 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 11:
The number 25 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 675639.04
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.

Advancing to step 12:
25 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 675639.04
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.

After the division, we end up with 675639.04 and a remainder of 0.0.
