90169 ÷ 25 
Let's see how many times 25 fits into 90169.

Advancing to step 1:
If we divide 9 by 25, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 25

Advancing to step 2:
When dividing 90 by 25, we get 3 with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 75 away from 90, we end up with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 25

Moving on to step 3:
151 divided by 25 is 6 with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
Deduct 150 from 151 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 25

Moving on to step 4:
The number 25 fits into 16 0 times, leaving a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 360.0
Deduct 0 from 16 and we're left with 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 25

Step 5:
25 goes into 169 6 times with a remainder of 19.
Put 6 as the next digit of the answer. 
Result so far: 3606.0
Subtracting 150 from 169 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 6:
The number 25 fits into 190 7 times, leaving a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 3606.7
If we subtract 175 from 190, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
25 goes into 150 6 times with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 3606.76
If we subtract 150 from 150, 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 8:
When dividing 0 by 25, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3606.76
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.

Advancing to step 9:
0 divided by 25 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3606.76
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 final outcome is 3606.76, with a leftover of 0.0.
