216593 ÷ 81 
We're looking to find how many times 81 goes into 216593.

Let's proceed to step 1:
2 divided by 81 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 81

On to step 2:
When dividing 21 by 81, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 81

Going ahead to step 3:
216 divided by 81 is 2 with a remainder of 54.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 162 from 216 and we're left with 54.
Take the next digit (5) from the dividend and append it to 54, then repeat: 545 / 81

Going ahead to step 4:
When dividing 545 by 81, we get 6 with a remainder of 59.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
Subtracting 486 from 545 leaves us with 59.
Fetch the next digit (9) from the dividend, attach it to 59 and continue: 599 / 81

Moving on to step 5:
599 divided by 81 is 7 with a remainder of 32.
The number 7 becomes the next digit in our result. 
Result so far: 267.0
If we take 567 away from 599, we end up with 32.
Take the next digit (3) from the dividend and append it to 32, then repeat: 323 / 81

Advancing to step 6:
When dividing 323 by 81, we get 3 with a remainder of 80.
Use 3 as the next digit of our solution. 
Result so far: 2673.0
If we subtract 243 from 323, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 7:
800 divided by 81 is 9 with a remainder of 71.
Record the quotient 9 as the next digit in the result. 
Result so far: 2673.9
Subtract 729 from 800 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 8:
The number 81 fits into 710 8 times, leaving a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 2673.98
Deduct 648 from 710 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 9:
The number 81 fits into 620 7 times, leaving a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 2673.987
The remainder is 53 after subtracting 567 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 10:
81 can be fit into 530 6 times, resulting in a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 2673.9876
If we take 486 away from 530, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 11:
81 can be fit into 440 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 2673.98765
If we take 405 away from 440, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 12:
When dividing 350 by 81, we get 4 with a remainder of 26.
Record the quotient 4 as the next digit in the result. 
Result so far: 2673.987654
If we take 324 away from 350, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 13:
When dividing 260 by 81, we get 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 2673.9876543
Deduct 243 from 260 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 14:
81 can be fit into 170 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2673.98765432
If we take 162 away from 170, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 2673.98765432, and the remainder is 8e-09.
