We're dividing 918543 by 20 
We want to figure out the number of times 918543 can be divided by 20.

Moving on to step 1:
9 divided by 20 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 20

Let's proceed to step 2:
The number 20 fits into 91 4 times, leaving a remainder of 11.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 11 after subtracting 80 from 91.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 20

Let's proceed to step 3:
The number 20 fits into 118 5 times, leaving a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 45.0
Subtract 100 from 118 to get 18.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 20

Let's proceed to step 4:
20 goes into 185 9 times with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 459.0
Subtract 180 from 185 to get 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 20

On to step 5:
20 goes into 54 2 times with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 4592.0
Subtracting 40 from 54 leaves us with 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 20

Going ahead to step 6:
20 can be fit into 143 7 times, resulting in a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 45927.0
If we subtract 140 from 143, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
20 can be fit into 30 1 times, resulting in a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 45927.1
The remainder is 10 after subtracting 20 from 30.
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:
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: 45927.15
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.

Advancing to step 9:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 45927.15
If we subtract 0 from 0, we 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 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 45927.15
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.

The final result is 45927.15 with a remainder of 0.0.
