We look at the division of 215115 by 73 
We're looking to find how many times 73 goes into 215115.

Advancing to step 1:
If we divide 2 by 73, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 73

Let's proceed to step 2:
73 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 73

Step 3:
The number 73 fits into 215 2 times, leaving a remainder of 69.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 146 from 215 leaves us with 69.
Include the next digit (1) from the dividend after 69, then repeat: 691 / 73

Advancing to step 4:
73 goes into 691 9 times with a remainder of 34.
Write down 9 as next digit of the result. 
Result so far: 29.0
If we subtract 657 from 691, we get 34.
Grab the next digit (1) from the dividend, add it to 34, then carry on: 341 / 73

Moving on to step 5:
When dividing 341 by 73, we get 4 with a remainder of 49.
Put 4 as the next digit of the answer. 
Result so far: 294.0
Subtract 292 from 341 to get 49.
Grab the next digit (5) from the dividend, add it to 49, then carry on: 495 / 73

Going ahead to step 6:
73 can be fit into 495 6 times, resulting in a remainder of 57.
Use 6 as the next digit of our solution. 
Result so far: 2946.0
Deduct 438 from 495 and we're left with 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 7:
When dividing 570 by 73, we get 7 with a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 2946.7
If we subtract 511 from 570, we 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 8:
When dividing 590 by 73, we get 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 2946.78
Deduct 584 from 590 and we're left 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.

Advancing to step 9:
73 goes into 60 0 times with a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 2946.78
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.

Let's proceed to step 10:
When dividing 600 by 73, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 2946.7808
Deduct 584 from 600 and we're left 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.

Let's proceed to step 11:
The number 73 fits into 160 2 times, leaving a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 2946.78082
Subtracting 146 from 160 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 12:
The number 73 fits into 140 1 times, leaving a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 2946.780821
If we subtract 73 from 140, we 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.

Let's proceed to step 13:
The number 73 fits into 670 9 times, leaving a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 2946.7808219
If we take 657 away from 670, we end up with 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 14:
130 divided by 73 is 1 with a remainder of 57.
Record the quotient 1 as the next digit in the result. 
Result so far: 2946.78082191
Subtracting 73 from 130 leaves us with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

In conclusion, the division gives 2946.78082191 with a balance of 5.7e-08.
