We look at the division of 286840 by 73 
We want to divide 286840 by 73.

Let's proceed to step 1:
2 divided by 73 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 73

Going ahead to step 2:
If we divide 28 by 73, we get 0 and a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Include the next digit (6) from the dividend after 28, then repeat: 286 / 73

Step 3:
If we divide 286 by 73, we get 3 and a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 219 from 286, we get 67.
Include the next digit (8) from the dividend after 67, then repeat: 678 / 73

Moving on to step 4:
73 goes into 678 9 times with a remainder of 21.
Write down 9 as next digit of the result. 
Result so far: 39.0
The remainder is 21 after subtracting 657 from 678.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 73

Advancing to step 5:
214 divided by 73 is 2 with a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 392.0
Deduct 146 from 214 and we're left with 68.
Fetch the next digit (0) from the dividend, attach it to 68 and continue: 680 / 73

On to step 6:
The number 73 fits into 680 9 times, leaving a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 3929.0
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.

Advancing to step 7:
When dividing 230 by 73, we get 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3929.3
If we take 219 away from 230, we end up 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.

Advancing to step 8:
73 can be fit into 110 1 times, resulting in a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 3929.31
If we take 73 away from 110, we end up with 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 9:
370 divided by 73 is 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 3929.315
Subtract 365 from 370 to 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.

Step 10:
If we divide 50 by 73, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 3929.315
Subtract 0 from 50 to 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.

Let's proceed to step 11:
If we divide 500 by 73, we get 6 and a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 3929.31506
If we subtract 438 from 500, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 12:
620 divided by 73 is 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 3929.315068
If we subtract 584 from 620, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
The number 73 fits into 360 4 times, leaving a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 3929.3150684
If we subtract 292 from 360, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 14:
73 can be fit into 680 9 times, resulting in a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 3929.31506849
Subtracting 657 from 680 leaves us 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.

After the division, we end up with 3929.31506849 and a remainder of 2.3e-08.
