20409 ÷ 94 
We want to figure out the number of times 20409 can be divided by 94.

Step 1:
If we divide 2 by 94, we get 0 and a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 94

Step 2:
94 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 94

Moving on to step 3:
The number 94 fits into 204 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 188 away from 204, we end up with 16.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 94

Advancing to step 4:
160 divided by 94 is 1 with a remainder of 66.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtract 94 from 160 to get 66.
Bring next digit (9) of the dividend behind the 66 and repeat the process: 669 / 94

Let's proceed to step 5:
94 goes into 669 7 times with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 217.0
If we take 658 away from 669, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 6:
110 divided by 94 is 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 217.1
The remainder is 16 after subtracting 94 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 7:
94 goes into 160 1 times with a remainder of 66.
Record the quotient 1 as the next digit in the result. 
Result so far: 217.11
The remainder is 66 after subtracting 94 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Our division results in 217.11 with a remaining 0.066.
