We look at the division of 401874 by 20 
Our goal is to divide 401874 by 20.

On to step 1:
When dividing 4 by 20, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 20

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
If we subtract 40 from 40, we get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 20

On to step 3:
When dividing 1 by 20, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 20.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 20

Let's proceed to step 4:
The number 20 fits into 18 0 times, leaving a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 200.0
Subtract 0 from 18 to get 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 20

Advancing to step 5:
When dividing 187 by 20, we get 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 2009.0
If we subtract 180 from 187, we get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 20

Going ahead to step 6:
The number 20 fits into 74 3 times, leaving a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 20093.0
Subtracting 60 from 74 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
20 can be fit into 140 7 times, resulting in a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 20093.7
If we take 140 away from 140, 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.

Let's proceed to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 20093.7
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.

Moving on to step 9:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20093.7
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.

After the division, we end up with 20093.7 and a remainder of 0.0.
