We're dividing 17231962 by 225 
Let's see how many times 225 fits into 17231962.

Step 1:
When dividing 1 by 225, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 225

On to step 2:
When dividing 17 by 225, we get 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 17 leaves us with 17.
Bring next digit (2) of the dividend behind the 17 and repeat the process: 172 / 225

Step 3:
When dividing 172 by 225, we get 0 with a remainder of 172.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 172 leaves us with 172.
Include the next digit (3) from the dividend after 172, then repeat: 1723 / 225

On to step 4:
1723 divided by 225 is 7 with a remainder of 148.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 1575 from 1723 to get 148.
Include the next digit (1) from the dividend after 148, then repeat: 1481 / 225

Let's proceed to step 5:
The number 225 fits into 1481 6 times, leaving a remainder of 131.
The number 6 becomes the next digit in our result. 
Result so far: 76.0
If we take 1350 away from 1481, we end up with 131.
Bring next digit (9) of the dividend behind the 131 and repeat the process: 1319 / 225

Going ahead to step 6:
1319 divided by 225 is 5 with a remainder of 194.
Use 5 as the next digit of our solution. 
Result so far: 765.0
If we take 1125 away from 1319, we end up with 194.
Take the next digit (6) from the dividend and append it to 194, then repeat: 1946 / 225

Advancing to step 7:
When dividing 1946 by 225, we get 8 with a remainder of 146.
The next digit of our result is 8. 
Result so far: 7658.0
The remainder is 146 after subtracting 1800 from 1946.
Append the next digit (2) from the dividend to 146 and continue with: 1462 / 225

Advancing to step 8:
225 goes into 1462 6 times with a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 76586.0
Deduct 1350 from 1462 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 9:
The number 225 fits into 1120 4 times, leaving a remainder of 220.
The next digit of our result is 4. 
Result so far: 76586.4
If we take 900 away from 1120, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 10:
When dividing 2200 by 225, we get 9 with a remainder of 175.
Put 9 as the next digit of the answer. 
Result so far: 76586.49
Subtracting 2025 from 2200 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 11:
225 can be fit into 1750 7 times, resulting in a remainder of 175.
The number 7 becomes the next digit in our result. 
Result so far: 76586.497
Subtracting 1575 from 1750 leaves us with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

Advancing to step 12:
If we divide 1750 by 225, we get 7 and a remainder of 175.
Use 7 as the next digit of our solution. 
Result so far: 76586.4977
If we take 1575 away from 1750, we end up with 175.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1750, and continue the process.

The final result is 76586.4977 with a remainder of 0.00175.
