We're dividing 867403 by 20 
We want to divide 867403 by 20.

Going ahead to step 1:
If we divide 8 by 20, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 20

Advancing to step 2:
When dividing 86 by 20, we get 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 80 from 86 to get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 20

Let's proceed to step 3:
When dividing 67 by 20, we get 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 43.0
Subtract 60 from 67 to get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 20

Going ahead to step 4:
When dividing 74 by 20, we get 3 with a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 433.0
The remainder is 14 after subtracting 60 from 74.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 20

Advancing to step 5:
20 goes into 140 7 times with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 4337.0
Subtract 140 from 140 to get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 20

Let's proceed to step 6:
3 divided by 20 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 43370.0
Subtracting 0 from 3 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
20 goes into 30 1 times with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 43370.1
If we subtract 20 from 30, 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.

Step 8:
20 goes into 100 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 43370.15
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.

Let's proceed to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 43370.15
Subtract 0 from 0 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.

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: 43370.15
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.

The final result is 43370.15 with a remainder of 0.0.
