We're dividing 20996 by 73 
Let's see how many times 73 fits into 20996.

On to step 1:
2 divided by 73 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 73

Moving on to step 2:
The number 73 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 73

On to step 3:
If we divide 209 by 73, we get 2 and a remainder of 63.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 146 from 209 and we're left with 63.
Grab the next digit (9) from the dividend, add it to 63, then carry on: 639 / 73

On to step 4:
73 goes into 639 8 times with a remainder of 55.
The next digit of our result is 8. 
Result so far: 28.0
Deduct 584 from 639 and we're left with 55.
Take the next digit (6) from the dividend and append it to 55, then repeat: 556 / 73

Going ahead to step 5:
73 can be fit into 556 7 times, resulting in a remainder of 45.
Record the quotient 7 as the next digit in the result. 
Result so far: 287.0
If we take 511 away from 556, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 6:
The number 73 fits into 450 6 times, leaving a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 287.6
The remainder is 12 after subtracting 438 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 7:
120 divided by 73 is 1 with a remainder of 47.
Write down 1 as next digit of the result. 
Result so far: 287.61
Subtracting 73 from 120 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 8:
The number 73 fits into 470 6 times, leaving a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 287.616
If we subtract 438 from 470, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
When dividing 320 by 73, we get 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 287.6164
If we take 292 away from 320, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 10:
The number 73 fits into 280 3 times, leaving a remainder of 61.
Put 3 as the next digit of the answer. 
Result so far: 287.61643
If we take 219 away from 280, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 11:
The number 73 fits into 610 8 times, leaving a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 287.616438
If we subtract 584 from 610, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
If we divide 260 by 73, we get 3 and a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 287.6164383
Deduct 219 from 260 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 13:
73 can be fit into 410 5 times, resulting in a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 287.61643835
Subtracting 365 from 410 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

The final result is 287.61643835 with a remainder of 4.5e-08.
