We're dividing 20899594 by 663 
We want to figure out the number of times 20899594 can be divided by 663.

Step 1:
663 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 663

Going ahead to step 2:
663 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Fetch the next digit (8) from the dividend, attach it to 20 and continue: 208 / 663

Moving on to step 3:
If we divide 208 by 663, we get 0 and a remainder of 208.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 208, we end up with 208.
Include the next digit (9) from the dividend after 208, then repeat: 2089 / 663

Advancing to step 4:
663 can be fit into 2089 3 times, resulting in a remainder of 100.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 1989 away from 2089, we end up with 100.
Take the next digit (9) from the dividend and append it to 100, then repeat: 1009 / 663

Going ahead to step 5:
The number 663 fits into 1009 1 times, leaving a remainder of 346.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtracting 663 from 1009 leaves us with 346.
Include the next digit (5) from the dividend after 346, then repeat: 3465 / 663

Moving on to step 6:
If we divide 3465 by 663, we get 5 and a remainder of 150.
Write down 5 as next digit of the result. 
Result so far: 315.0
If we take 3315 away from 3465, we end up with 150.
Take the next digit (9) from the dividend and append it to 150, then repeat: 1509 / 663

Let's proceed to step 7:
If we divide 1509 by 663, we get 2 and a remainder of 183.
The number 2 becomes the next digit in our result. 
Result so far: 3152.0
Deduct 1326 from 1509 and we're left with 183.
Include the next digit (4) from the dividend after 183, then repeat: 1834 / 663

Step 8:
663 goes into 1834 2 times with a remainder of 508.
The number 2 becomes the next digit in our result. 
Result so far: 31522.0
Subtract 1326 from 1834 to get 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Advancing to step 9:
663 can be fit into 5080 7 times, resulting in a remainder of 439.
The number 7 becomes the next digit in our result. 
Result so far: 31522.7
Subtracting 4641 from 5080 leaves us with 439.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4390, and continue the process.

On to step 10:
4390 divided by 663 is 6 with a remainder of 412.
The number 6 becomes the next digit in our result. 
Result so far: 31522.76
Subtract 3978 from 4390 to get 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Step 11:
663 can be fit into 4120 6 times, resulting in a remainder of 142.
The number 6 becomes the next digit in our result. 
Result so far: 31522.766
Deduct 3978 from 4120 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Our division results in 31522.766 with a remaining 0.0142.
