We look at the division of 217405 by 73 
Let's see how many times 73 fits into 217405.

Step 1:
73 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 73

Step 2:
The number 73 fits into 21 0 times, leaving a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Append the next digit (7) from the dividend to 21 and continue with: 217 / 73

Moving on to step 3:
73 can be fit into 217 2 times, resulting in a remainder of 71.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 146 away from 217, we end up with 71.
Bring next digit (4) of the dividend behind the 71 and repeat the process: 714 / 73

Going ahead to step 4:
73 can be fit into 714 9 times, resulting in a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Subtract 657 from 714 to get 57.
Fetch the next digit (0) from the dividend, attach it to 57 and continue: 570 / 73

Going ahead to step 5:
If we divide 570 by 73, we get 7 and a remainder of 59.
Write down 7 as next digit of the result. 
Result so far: 297.0
If we subtract 511 from 570, we get 59.
Fetch the next digit (5) from the dividend, attach it to 59 and continue: 595 / 73

Advancing to step 6:
The number 73 fits into 595 8 times, leaving a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 2978.0
Deduct 584 from 595 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
When dividing 110 by 73, we get 1 with a remainder of 37.
The number 1 becomes the next digit in our result. 
Result so far: 2978.1
If we subtract 73 from 110, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 8:
If we divide 370 by 73, we get 5 and a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 2978.15
If we subtract 365 from 370, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
73 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 2978.15
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
If we divide 500 by 73, we get 6 and a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 2978.1506
Subtracting 438 from 500 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 11:
73 goes into 620 8 times with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 2978.15068
Subtracting 584 from 620 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
73 can be fit into 360 4 times, resulting in a remainder of 68.
The next digit of our result is 4. 
Result so far: 2978.150684
Subtracting 292 from 360 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 13:
73 goes into 680 9 times with a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 2978.1506849
If we take 657 away from 680, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 14:
The number 73 fits into 230 3 times, leaving a remainder of 11.
The next digit of our result is 3. 
Result so far: 2978.15068493
If we subtract 219 from 230, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

After the division, we end up with 2978.15068493 and a remainder of 1.1e-08.
