246426 divided by 20 
Let's see how many times 20 fits into 246426.

Step 1:
20 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 20

On to step 2:
If we divide 24 by 20, we get 1 and a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 20 from 24, we get 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 20

On to step 3:
The number 20 fits into 46 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 40 from 46 to get 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 20

Going ahead to step 4:
64 divided by 20 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 123.0
Subtracting 60 from 64 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 20

Let's proceed to step 5:
20 goes into 42 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 1232.0
The remainder is 2 after subtracting 40 from 42.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 20

Advancing to step 6:
If we divide 26 by 20, we get 1 and a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 12321.0
The remainder is 6 after subtracting 20 from 26.
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.
Record the quotient 3 as the next digit in the result. 
Result so far: 12321.3
Deduct 60 from 60 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.

Advancing to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12321.3
If we take 0 away from 0, we end up 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.
Write down 0 as next digit of the result. 
Result so far: 12321.3
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.

The final result is 12321.3 with a remainder of 0.0.
