919540 divided by 20 
Our goal is to divide 919540 by 20.

Step 1:
The number 20 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 20

Moving on to step 2:
91 divided by 20 is 4 with a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 4.0
The remainder is 11 after subtracting 80 from 91.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 20

Moving on to step 3:
When dividing 119 by 20, we get 5 with a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtracting 100 from 119 leaves us with 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 20

Moving on to step 4:
195 divided by 20 is 9 with a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 459.0
If we subtract 180 from 195, we get 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 20

Let's proceed to step 5:
When dividing 154 by 20, we get 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 4597.0
Deduct 140 from 154 and we're left with 14.
Include the next digit (0) from the dividend after 14, then repeat: 140 / 20

Going ahead to step 6:
140 divided by 20 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 45977.0
Subtract 140 from 140 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 7:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 45977.0
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.

Going ahead to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 45977.0
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.

After the division, we end up with 45977.0 and a remainder of 0.0.
