543574 divided by 20 
We're looking to find how many times 20 goes into 543574.

Step 1:
The number 20 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 20

Going ahead to step 2:
When dividing 54 by 20, we get 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 40 from 54, we get 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 20

Advancing to step 3:
When dividing 143 by 20, we get 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
If we take 140 away from 143, we end up with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 20

Advancing to step 4:
The number 20 fits into 35 1 times, leaving a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 271.0
If we subtract 20 from 35, we get 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 20

Moving on to step 5:
The number 20 fits into 157 7 times, leaving a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 2717.0
Subtract 140 from 157 to get 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 20

On to step 6:
20 can be fit into 174 8 times, resulting in a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 27178.0
Deduct 160 from 174 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
20 goes into 140 7 times with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 27178.7
Subtracting 140 from 140 leaves us 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.

Step 8:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 27178.7
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.

Advancing to 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: 27178.7
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.

The final outcome is 27178.7, with a leftover of 0.0.
