We're dividing 54005603 by 20 
We're looking to find how many times 20 goes into 54005603.

Moving on to step 1:
20 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 20

On to step 2:
20 goes into 54 2 times with a remainder of 14.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 40 from 54 leaves us with 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 20

Step 3:
If we divide 140 by 20, we get 7 and a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
Subtracting 140 from 140 leaves us with 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 20

Advancing to step 4:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 270.0
If we subtract 0 from 0, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 20

Moving on to step 5:
When dividing 5 by 20, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 2700.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 20

Advancing to step 6:
20 can be fit into 56 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 27002.0
The remainder is 16 after subtracting 40 from 56.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 20

Moving on to step 7:
160 divided by 20 is 8 with a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 270028.0
Deduct 160 from 160 and we're left with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 20

Going ahead to step 8:
If we divide 3 by 20, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 2700280.0
Subtract 0 from 3 to 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.

Going ahead to step 9:
If we divide 30 by 20, we get 1 and a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 2700280.1
If we take 20 away from 30, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
20 can be fit into 100 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 2700280.15
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.

Going ahead to step 11:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 2700280.15
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.

Going ahead to step 12:
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: 2700280.15
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 quotient of the division is 2700280.15, and the remainder is 0.0.
