646953 ÷ 20 
Let's see how many times 20 fits into 646953.

On to step 1:
20 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 20

Let's proceed to step 2:
64 divided by 20 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 60 from 64 and we're left with 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 20

Advancing to step 3:
If we divide 46 by 20, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 32.0
Subtracting 40 from 46 leaves us with 6.
Fetch the next digit (9) from the dividend, attach it to 6 and continue: 69 / 20

Step 4:
If we divide 69 by 20, we get 3 and a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 323.0
Deduct 60 from 69 and we're left with 9.
Grab the next digit (5) from the dividend, add it to 9, then carry on: 95 / 20

Going ahead to step 5:
The number 20 fits into 95 4 times, leaving a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 3234.0
If we take 80 away from 95, we end up with 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 20

Let's proceed to step 6:
When dividing 153 by 20, we get 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 32347.0
Deduct 140 from 153 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 7:
130 divided by 20 is 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 32347.6
If we take 120 away from 130, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
20 goes into 100 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 32347.65
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.

On to step 9:
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: 32347.65
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.

Advancing to step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 32347.65
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.

Our division results in 32347.65 with a remaining 0.0.
