We're dividing 15973 by 73 
Let's see how many times 73 fits into 15973.

Step 1:
When dividing 1 by 73, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 73

Let's proceed to step 2:
73 goes into 15 0 times with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Grab the next digit (9) from the dividend, add it to 15, then carry on: 159 / 73

Moving on to step 3:
159 divided by 73 is 2 with a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 13 after subtracting 146 from 159.
Bring next digit (7) of the dividend behind the 13 and repeat the process: 137 / 73

Moving on to step 4:
The number 73 fits into 137 1 times, leaving a remainder of 64.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Deduct 73 from 137 and we're left with 64.
Include the next digit (3) from the dividend after 64, then repeat: 643 / 73

Going ahead to step 5:
73 goes into 643 8 times with a remainder of 59.
The next digit of our result is 8. 
Result so far: 218.0
Subtract 584 from 643 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 6:
590 divided by 73 is 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 218.8
If we take 584 away from 590, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
When dividing 60 by 73, we get 0 with a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 218.8
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 8:
600 divided by 73 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 218.808
If we take 584 away from 600, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 9:
73 can be fit into 160 2 times, resulting in a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 218.8082
The remainder is 14 after subtracting 146 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 10:
73 can be fit into 140 1 times, resulting in a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 218.80821
Subtract 73 from 140 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 11:
If we divide 670 by 73, we get 9 and a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 218.808219
If we subtract 657 from 670, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 12:
73 goes into 130 1 times with a remainder of 57.
The number 1 becomes the next digit in our result. 
Result so far: 218.8082191
Subtract 73 from 130 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Let's proceed to step 13:
If we divide 570 by 73, we get 7 and a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 218.80821917
Subtracting 511 from 570 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

The final outcome is 218.80821917, with a leftover of 5.9e-08.
