20781 ÷ 39 
Let's see how many times 39 fits into 20781.

Let's proceed to step 1:
If we divide 2 by 39, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 39

Advancing to step 2:
If we divide 20 by 39, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 39

Moving on to step 3:
207 divided by 39 is 5 with a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 195 from 207 and we're left with 12.
Fetch the next digit (8) from the dividend, attach it to 12 and continue: 128 / 39

Step 4:
39 goes into 128 3 times with a remainder of 11.
The next digit of our result is 3. 
Result so far: 53.0
The remainder is 11 after subtracting 117 from 128.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 39

Moving on to step 5:
When dividing 111 by 39, we get 2 with a remainder of 33.
The number 2 becomes the next digit in our result. 
Result so far: 532.0
If we take 78 away from 111, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 6:
330 divided by 39 is 8 with a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 532.8
If we subtract 312 from 330, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
39 can be fit into 180 4 times, resulting in a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 532.84
If we subtract 156 from 180, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 8:
The number 39 fits into 240 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 532.846
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
The number 39 fits into 60 1 times, leaving a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 532.8461
If we take 39 away from 60, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 10:
When dividing 210 by 39, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 532.84615
If we subtract 195 from 210, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
39 can be fit into 150 3 times, resulting in a remainder of 33.
The next digit of our result is 3. 
Result so far: 532.846153
Subtract 117 from 150 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 12:
39 goes into 330 8 times with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 532.8461538
The remainder is 18 after subtracting 312 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 13:
The number 39 fits into 180 4 times, leaving a remainder of 24.
The next digit of our result is 4. 
Result so far: 532.84615384
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 532.84615384 with a remaining 2.4e-08.
