We're dividing 725890 by 20 
We want to divide 725890 by 20.

Moving on to step 1:
7 divided by 20 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 20

On to step 2:
When dividing 72 by 20, we get 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 60 from 72 and we're left with 12.
Take the next digit (5) from the dividend and append it to 12, then repeat: 125 / 20

Going ahead to step 3:
125 divided by 20 is 6 with a remainder of 5.
The next digit of our result is 6. 
Result so far: 36.0
Deduct 120 from 125 and we're left with 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 20

Step 4:
20 goes into 58 2 times with a remainder of 18.
The next digit of our result is 2. 
Result so far: 362.0
The remainder is 18 after subtracting 40 from 58.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 20

On to step 5:
If we divide 189 by 20, we get 9 and a remainder of 9.
Use 9 as the next digit of our solution. 
Result so far: 3629.0
Deduct 180 from 189 and we're left with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 20

Let's proceed to step 6:
When dividing 90 by 20, we get 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 36294.0
The remainder is 10 after subtracting 80 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
If we divide 100 by 20, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 36294.5
Subtract 100 from 100 to 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.

Advancing to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 36294.5
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.

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: 36294.5
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.

After the division, we end up with 36294.5 and a remainder of 0.0.
