516785 divided by 20 
We're looking to find how many times 20 goes into 516785.

On to step 1:
20 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 20

Let's proceed to step 2:
When dividing 51 by 20, we get 2 with a remainder of 11.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 40 from 51 and we're left with 11.
Grab the next digit (6) from the dividend, add it to 11, then carry on: 116 / 20

Moving on to step 3:
20 goes into 116 5 times with a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtract 100 from 116 to get 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 20

Let's proceed to step 4:
If we divide 167 by 20, we get 8 and a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 258.0
If we take 160 away from 167, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 20

Going ahead to step 5:
20 can be fit into 78 3 times, resulting in a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 2583.0
The remainder is 18 after subtracting 60 from 78.
Take the next digit (5) from the dividend and append it to 18, then repeat: 185 / 20

On to step 6:
185 divided by 20 is 9 with a remainder of 5.
The number 9 becomes the next digit in our result. 
Result so far: 25839.0
If we take 180 away from 185, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
20 goes into 50 2 times with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 25839.2
If we subtract 40 from 50, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
100 divided by 20 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 25839.25
Deduct 100 from 100 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 25839.25
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 25839.25
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 25839.25, and the remainder is 0.0.
