634685 divided by 20 
We're looking to find how many times 20 goes into 634685.

Advancing to step 1:
6 divided by 20 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 20

Going ahead to step 2:
If we divide 63 by 20, we get 3 and a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 60 from 63 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 20

Moving on to step 3:
If we divide 34 by 20, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
Subtract 20 from 34 to get 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 20

Step 4:
20 can be fit into 146 7 times, resulting in a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 317.0
If we subtract 140 from 146, we get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 20

Going ahead to step 5:
20 goes into 68 3 times with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 3173.0
Deduct 60 from 68 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 20

Let's proceed to step 6:
The number 20 fits into 85 4 times, leaving a remainder of 5.
Use 4 as the next digit of our solution. 
Result so far: 31734.0
Subtracting 80 from 85 leaves us 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.

Let's proceed to step 7:
If we divide 50 by 20, we get 2 and a remainder of 10.
The next digit of our result is 2. 
Result so far: 31734.2
Subtract 40 from 50 to 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.

On to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 31734.25
Subtracting 100 from 100 leaves us 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.

Step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 31734.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 31734.25
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.

After the division, we end up with 31734.25 and a remainder of 0.0.
