We look at the division of 209972 by 73 
We want to figure out the number of times 209972 can be divided by 73.

Step 1:
When dividing 2 by 73, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 73

Advancing to step 2:
If we divide 20 by 73, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 73

Moving on to step 3:
If we divide 209 by 73, we get 2 and a remainder of 63.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 146 from 209 to get 63.
Bring next digit (9) of the dividend behind the 63 and repeat the process: 639 / 73

Let's proceed to step 4:
73 goes into 639 8 times with a remainder of 55.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we take 584 away from 639, we end up with 55.
Take the next digit (7) from the dividend and append it to 55, then repeat: 557 / 73

Advancing to step 5:
73 goes into 557 7 times with a remainder of 46.
Record the quotient 7 as the next digit in the result. 
Result so far: 287.0
Subtracting 511 from 557 leaves us with 46.
Take the next digit (2) from the dividend and append it to 46, then repeat: 462 / 73

On to step 6:
If we divide 462 by 73, we get 6 and a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 2876.0
The remainder is 24 after subtracting 438 from 462.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 7:
The number 73 fits into 240 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 2876.3
Deduct 219 from 240 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 8:
The number 73 fits into 210 2 times, leaving a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 2876.32
Deduct 146 from 210 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 9:
The number 73 fits into 640 8 times, leaving a remainder of 56.
The number 8 becomes the next digit in our result. 
Result so far: 2876.328
Deduct 584 from 640 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 10:
If we divide 560 by 73, we get 7 and a remainder of 49.
Record the quotient 7 as the next digit in the result. 
Result so far: 2876.3287
Deduct 511 from 560 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 11:
73 goes into 490 6 times with a remainder of 52.
The next digit of our result is 6. 
Result so far: 2876.32876
If we subtract 438 from 490, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 12:
When dividing 520 by 73, we get 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 2876.328767
The remainder is 9 after subtracting 511 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 13:
90 divided by 73 is 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 2876.3287671
Deduct 73 from 90 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 14:
170 divided by 73 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 2876.32876712
Subtracting 146 from 170 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 2876.32876712, with a leftover of 2.4e-08.
