We look at the division of 543426 by 20 
We want to figure out the number of times 543426 can be divided by 20.

Advancing to step 1:
20 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 20

Let's proceed to step 2:
20 can be fit into 54 2 times, resulting in a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 40 away from 54, we end up with 14.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 20

Going ahead to step 3:
The number 20 fits into 143 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 27.0
Deduct 140 from 143 and we're left with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 20

Going ahead to step 4:
If we divide 34 by 20, we get 1 and a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 271.0
Subtracting 20 from 34 leaves us with 14.
Include the next digit (2) from the dividend after 14, then repeat: 142 / 20

Step 5:
20 goes into 142 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 2717.0
Subtracting 140 from 142 leaves us with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 20

Going ahead to step 6:
When dividing 26 by 20, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 27171.0
The remainder is 6 after subtracting 20 from 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
If we divide 60 by 20, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 27171.3
If we take 60 away from 60, 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.

On to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 27171.3
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 9:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 27171.3
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.

The final outcome is 27171.3, with a leftover of 0.0.
