245858 ÷ 20 
We want to divide 245858 by 20.

Moving on to step 1:
The number 20 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 20

Step 2:
24 divided by 20 is 1 with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 4 after subtracting 20 from 24.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 20

Moving on to step 3:
20 can be fit into 45 2 times, resulting in a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtract 40 from 45 to get 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 20

Advancing to step 4:
58 divided by 20 is 2 with a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 122.0
The remainder is 18 after subtracting 40 from 58.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 20

Moving on to step 5:
20 goes into 185 9 times with a remainder of 5.
The next digit of our result is 9. 
Result so far: 1229.0
If we take 180 away from 185, we end up with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 20

On to step 6:
58 divided by 20 is 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 12292.0
The remainder is 18 after subtracting 40 from 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
If we divide 180 by 20, we get 9 and a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 12292.9
If we subtract 180 from 180, 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:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12292.9
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 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12292.9
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 quotient of the division is 12292.9, and the remainder is 0.0.
