We're dividing 290121 by 20 
Our goal is to divide 290121 by 20.

Moving on to step 1:
If we divide 2 by 20, 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.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 20

Moving on to step 2:
If we divide 29 by 20, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 20 from 29 and we're left with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 20

Let's proceed to step 3:
The number 20 fits into 90 4 times, leaving a remainder of 10.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 80 from 90 leaves us with 10.
Include the next digit (1) from the dividend after 10, then repeat: 101 / 20

Let's proceed to step 4:
If we divide 101 by 20, we get 5 and a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 145.0
Deduct 100 from 101 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 20

Advancing to step 5:
The number 20 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 1450.0
Subtracting 0 from 12 leaves us with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 20

Let's proceed to step 6:
If we divide 121 by 20, we get 6 and a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 14506.0
If we take 120 away from 121, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
When dividing 10 by 20, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 14506.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
100 divided by 20 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 14506.05
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.

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: 14506.05
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.

Step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 14506.05
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.

The final result is 14506.05 with a remainder of 0.0.
