We're dividing 512210 by 73 
We're looking to find how many times 73 goes into 512210.

Going ahead to step 1:
When dividing 5 by 73, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 73

Let's proceed to step 2:
If we divide 51 by 73, we get 0 and a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Bring next digit (2) of the dividend behind the 51 and repeat the process: 512 / 73

Moving on to step 3:
512 divided by 73 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 511 from 512 to get 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 73

Moving on to step 4:
73 can be fit into 12 0 times, resulting in a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 70.0
If we subtract 0 from 12, we get 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 73

Moving on to step 5:
73 goes into 121 1 times with a remainder of 48.
Put 1 as the next digit of the answer. 
Result so far: 701.0
The remainder is 48 after subtracting 73 from 121.
Bring next digit (0) of the dividend behind the 48 and repeat the process: 480 / 73

Step 6:
73 can be fit into 480 6 times, resulting in a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 7016.0
The remainder is 42 after subtracting 438 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 7:
If we divide 420 by 73, we get 5 and a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 7016.5
If we subtract 365 from 420, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 8:
The number 73 fits into 550 7 times, leaving a remainder of 39.
Write down 7 as next digit of the result. 
Result so far: 7016.57
If we subtract 511 from 550, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
The number 73 fits into 390 5 times, leaving a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 7016.575
The remainder is 25 after subtracting 365 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
When dividing 250 by 73, we get 3 with a remainder of 31.
Write down 3 as next digit of the result. 
Result so far: 7016.5753
Subtracting 219 from 250 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 11:
310 divided by 73 is 4 with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 7016.57534
If we subtract 292 from 310, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 12:
When dividing 180 by 73, we get 2 with a remainder of 34.
The next digit of our result is 2. 
Result so far: 7016.575342
Deduct 146 from 180 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 13:
340 divided by 73 is 4 with a remainder of 48.
The number 4 becomes the next digit in our result. 
Result so far: 7016.5753424
The remainder is 48 after subtracting 292 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 14:
When dividing 480 by 73, we get 6 with a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 7016.57534246
If we take 438 away from 480, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

After the division, we end up with 7016.57534246 and a remainder of 4.2e-08.
