We're dividing 16945 by 81 
Our goal is to divide 16945 by 81.

Going ahead to step 1:
81 goes into 1 0 times 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.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 81

Let's proceed to step 2:
If we divide 16 by 81, we get 0 and a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 16 after subtracting 0 from 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 81

Let's proceed to step 3:
81 goes into 169 2 times with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 162 from 169 and we're left with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 81

Let's proceed to step 4:
When dividing 74 by 81, we get 0 with a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we take 0 away from 74, we end up with 74.
Fetch the next digit (5) from the dividend, attach it to 74 and continue: 745 / 81

Let's proceed to step 5:
The number 81 fits into 745 9 times, leaving a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 209.0
Subtract 729 from 745 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.

Let's proceed to step 6:
81 goes into 160 1 times with a remainder of 79.
Use 1 as the next digit of our solution. 
Result so far: 209.1
If we subtract 81 from 160, we 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.

Moving on to step 7:
When dividing 790 by 81, we get 9 with a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 209.19
If we subtract 729 from 790, we get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 8:
81 can be fit into 610 7 times, resulting in a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 209.197
The remainder is 43 after subtracting 567 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Step 9:
When dividing 430 by 81, we get 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 209.1975
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.

Let's proceed to step 10:
81 can be fit into 250 3 times, resulting in a remainder of 7.
The next digit of our result is 3. 
Result so far: 209.19753
The remainder is 7 after subtracting 243 from 250.
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 11:
81 goes into 70 0 times with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 209.19753
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 12:
81 goes into 700 8 times with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 209.1975308
The remainder is 52 after subtracting 648 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 13:
520 divided by 81 is 6 with a remainder of 34.
Record the quotient 6 as the next digit in the result. 
Result so far: 209.19753086
If we take 486 away from 520, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

After the division, we end up with 209.19753086 and a remainder of 3.4e-08.
