We divide 17229186 by 81
Our goal is to divide 17229186 by 81.

Step 1:
When dividing 1 by 81, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 81

Let's proceed to step 2:
81 goes into 17 0 times with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 17, we get 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 81

Advancing to step 3:
81 can be fit into 172 2 times, resulting in a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 162 from 172 leaves us with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 81

Moving on to step 4:
When dividing 102 by 81, we get 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 21.0
If we take 81 away from 102, we end up with 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 81

Going ahead to step 5:
81 goes into 219 2 times with a remainder of 57.
The next digit of our result is 2. 
Result so far: 212.0
Subtracting 162 from 219 leaves us with 57.
Fetch the next digit (1) from the dividend, attach it to 57 and continue: 571 / 81

Going ahead to step 6:
571 divided by 81 is 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 2127.0
If we take 567 away from 571, we end up with 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 81

On to step 7:
When dividing 48 by 81, we get 0 with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 21270.0
Subtract 0 from 48 to get 48.
Append the next digit (6) from the dividend to 48 and continue with: 486 / 81

Going ahead to step 8:
If we divide 486 by 81, we get 6 and a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 212706.0
If we subtract 486 from 486, 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 9:
81 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 212706.0
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.

Going ahead to step 10:
81 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 212706.0
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.

Our division results in 212706.0 with a remaining 0.0.
