1708 divided by 81 
Our goal is to divide 1708 by 81.

Moving on to step 1:
When dividing 1 by 81, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 81

Moving on to step 2:
The number 81 fits into 17 0 times, leaving 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.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 81

Advancing to step 3:
81 goes into 170 2 times with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 162 away from 170, we end up with 8.
Append the next digit (8) from the dividend to 8 and continue with: 88 / 81

Going ahead to step 4:
When dividing 88 by 81, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 21.0
Subtracting 81 from 88 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 5:
81 goes into 70 0 times with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 21.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 6:
If we divide 700 by 81, we get 8 and a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 21.08
Subtract 648 from 700 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 7:
When dividing 520 by 81, we get 6 with a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 21.086
If we subtract 486 from 520, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 8:
When dividing 340 by 81, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 21.0864
Subtract 324 from 340 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
If we divide 160 by 81, we get 1 and a remainder of 79.
Put 1 as the next digit of the answer. 
Result so far: 21.08641
Subtract 81 from 160 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Step 10:
The number 81 fits into 790 9 times, leaving a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 21.086419
The remainder is 61 after subtracting 729 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 11:
The number 81 fits into 610 7 times, leaving a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 21.0864197
If we take 567 away from 610, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 12:
430 divided by 81 is 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 21.08641975
If we subtract 405 from 430, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 21.08641975 and a remainder of 2.5e-08.
