Let's divide 255170 by 81
We want to figure out the number of times 255170 can be divided by 81.

Going ahead to step 1:
2 divided by 81 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 81

Moving on to step 2:
25 divided by 81 is 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 81

Moving on to step 3:
255 divided by 81 is 3 with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 12 after subtracting 243 from 255.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 81

Advancing to step 4:
121 divided by 81 is 1 with a remainder of 40.
The next digit of our result is 1. 
Result so far: 31.0
Subtract 81 from 121 to get 40.
Fetch the next digit (7) from the dividend, attach it to 40 and continue: 407 / 81

Moving on to step 5:
407 divided by 81 is 5 with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 315.0
The remainder is 2 after subtracting 405 from 407.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 81

Let's proceed to step 6:
When dividing 20 by 81, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 3150.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 7:
When dividing 200 by 81, we get 2 with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 3150.2
The remainder is 38 after subtracting 162 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 8:
If we divide 380 by 81, we get 4 and a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 3150.24
Subtract 324 from 380 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 9:
The number 81 fits into 560 6 times, leaving a remainder of 74.
The number 6 becomes the next digit in our result. 
Result so far: 3150.246
Deduct 486 from 560 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 10:
If we divide 740 by 81, we get 9 and a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 3150.2469
The remainder is 11 after subtracting 729 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 11:
If we divide 110 by 81, we get 1 and a remainder of 29.
The next digit of our result is 1. 
Result so far: 3150.24691
Subtracting 81 from 110 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 12:
The number 81 fits into 290 3 times, leaving a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 3150.246913
The remainder is 47 after subtracting 243 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 13:
81 can be fit into 470 5 times, resulting in a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 3150.2469135
If we take 405 away from 470, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Going ahead to step 14:
The number 81 fits into 650 8 times, leaving a remainder of 2.
The next digit of our result is 8. 
Result so far: 3150.24691358
Deduct 648 from 650 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 3150.24691358 and a remainder of 2e-09.
