470166 ÷ 20 
We're looking to find how many times 20 goes into 470166.

Let's proceed to step 1:
When dividing 4 by 20, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 20

Going ahead to step 2:
If we divide 47 by 20, we get 2 and a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 7 after subtracting 40 from 47.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 20

Step 3:
20 goes into 70 3 times with a remainder of 10.
The next digit of our result is 3. 
Result so far: 23.0
If we take 60 away from 70, we end up with 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 20

Going ahead to step 4:
101 divided by 20 is 5 with a remainder of 1.
The next digit of our result is 5. 
Result so far: 235.0
If we take 100 away from 101, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 20

Advancing to step 5:
When dividing 16 by 20, we get 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 2350.0
Subtract 0 from 16 to get 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 20

Let's proceed to step 6:
When dividing 166 by 20, we get 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 23508.0
The remainder is 6 after subtracting 160 from 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
60 divided by 20 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 23508.3
If we subtract 60 from 60, 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.

Going ahead to step 8:
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: 23508.3
Subtracting 0 from 0 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:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 23508.3
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.

After the division, we end up with 23508.3 and a remainder of 0.0.
