We're dividing 11163595 by 20 
Let's see how many times 20 fits into 11163595.

Step 1:
If we divide 1 by 20, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 20

Step 2:
11 divided by 20 is 0 with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Grab the next digit (1) from the dividend, add it to 11, then carry on: 111 / 20

Going ahead to step 3:
When dividing 111 by 20, we get 5 with a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 100 away from 111, we end up with 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 20

On to step 4:
The number 20 fits into 116 5 times, leaving a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 55.0
The remainder is 16 after subtracting 100 from 116.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 20

On to step 5:
20 goes into 163 8 times with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 558.0
If we take 160 away from 163, we end up with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 20

Step 6:
The number 20 fits into 35 1 times, leaving a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 5581.0
If we take 20 away from 35, we end up with 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 20

Step 7:
20 can be fit into 159 7 times, resulting in a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 55817.0
Subtract 140 from 159 to get 19.
Append the next digit (5) from the dividend to 19 and continue with: 195 / 20

Moving on to step 8:
When dividing 195 by 20, we get 9 with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 558179.0
Subtract 180 from 195 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
The number 20 fits into 150 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 558179.7
If we subtract 140 from 150, we get 10.
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 10:
20 goes into 100 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 558179.75
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 11:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 558179.75
The remainder is 0 after subtracting 0 from 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:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 558179.75
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 558179.75 with a remainder of 0.0.
