We divide 211502 by 81
We're looking to find how many times 81 goes into 211502.

Let's proceed to step 1:
If we divide 2 by 81, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 81

Advancing to step 2:
21 divided by 81 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 81

Advancing to step 3:
81 can be fit into 211 2 times, resulting in a remainder of 49.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 162 from 211 leaves us with 49.
Include the next digit (5) from the dividend after 49, then repeat: 495 / 81

On to step 4:
The number 81 fits into 495 6 times, leaving a remainder of 9.
Put 6 as the next digit of the answer. 
Result so far: 26.0
If we take 486 away from 495, we end up with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 81

Going ahead to step 5:
90 divided by 81 is 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 261.0
Subtract 81 from 90 to get 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 81

Moving on to step 6:
92 divided by 81 is 1 with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 2611.0
Deduct 81 from 92 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
If we divide 110 by 81, we get 1 and a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 2611.1
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.

Moving on to step 8:
81 can be fit into 290 3 times, resulting in a remainder of 47.
Record the quotient 3 as the next digit in the result. 
Result so far: 2611.13
Subtracting 243 from 290 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 9:
If we divide 470 by 81, we get 5 and a remainder of 65.
Put 5 as the next digit of the answer. 
Result so far: 2611.135
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.

Advancing to step 10:
81 goes into 650 8 times with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 2611.1358
If we take 648 away from 650, we end up 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.

Step 11:
The number 81 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 2611.1358
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
200 divided by 81 is 2 with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 2611.135802
If we take 162 away from 200, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 13:
380 divided by 81 is 4 with a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 2611.1358024
If we subtract 324 from 380, we 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.

Moving on to step 14:
560 divided by 81 is 6 with a remainder of 74.
Use 6 as the next digit of our solution. 
Result so far: 2611.13580246
Subtract 486 from 560 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The final result is 2611.13580246 with a remainder of 7.4e-08.
