Let's divide 401930 by 20
Let's see how many times 20 fits into 401930.

Let's proceed to step 1:
If we divide 4 by 20, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 20

On to step 2:
The number 20 fits into 40 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 40 from 40 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 20

Going ahead to step 3:
1 divided by 20 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtract 0 from 1 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 20

On to step 4:
If we divide 19 by 20, we get 0 and a remainder of 19.
The next digit of our result is 0. 
Result so far: 200.0
Subtract 0 from 19 to get 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 20

Advancing to step 5:
193 divided by 20 is 9 with a remainder of 13.
The next digit of our result is 9. 
Result so far: 2009.0
Subtracting 180 from 193 leaves us with 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 20

Step 6:
If we divide 130 by 20, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 20096.0
If we subtract 120 from 130, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
100 divided by 20 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 20096.5
Deduct 100 from 100 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.

Let's proceed to step 8:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20096.5
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.

Advancing to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 20096.5
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.

The final outcome is 20096.5, with a leftover of 0.0.
