We look at the division of 648158 by 73 
We're looking to find how many times 73 goes into 648158.

On to step 1:
When dividing 6 by 73, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 73

On to step 2:
If we divide 64 by 73, we get 0 and a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Bring next digit (8) of the dividend behind the 64 and repeat the process: 648 / 73

On to step 3:
When dividing 648 by 73, we get 8 with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 584 from 648, we get 64.
Grab the next digit (1) from the dividend, add it to 64, then carry on: 641 / 73

Step 4:
641 divided by 73 is 8 with a remainder of 57.
Use 8 as the next digit of our solution. 
Result so far: 88.0
Subtract 584 from 641 to get 57.
Append the next digit (5) from the dividend to 57 and continue with: 575 / 73

Going ahead to step 5:
575 divided by 73 is 7 with a remainder of 64.
The next digit of our result is 7. 
Result so far: 887.0
Subtract 511 from 575 to get 64.
Fetch the next digit (8) from the dividend, attach it to 64 and continue: 648 / 73

Step 6:
The number 73 fits into 648 8 times, leaving a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 8878.0
If we take 584 away from 648, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 7:
If we divide 640 by 73, we get 8 and a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 8878.8
Deduct 584 from 640 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 8:
73 can be fit into 560 7 times, resulting in a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 8878.87
Subtracting 511 from 560 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
When dividing 490 by 73, we get 6 with a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 8878.876
The remainder is 52 after subtracting 438 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 10:
520 divided by 73 is 7 with a remainder of 9.
The number 7 becomes the next digit in our result. 
Result so far: 8878.8767
If we subtract 511 from 520, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 11:
When dividing 90 by 73, we get 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 8878.87671
The remainder is 17 after subtracting 73 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 12:
If we divide 170 by 73, we get 2 and a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 8878.876712
Subtracting 146 from 170 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
73 can be fit into 240 3 times, resulting in a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 8878.8767123
If we subtract 219 from 240, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 14:
The number 73 fits into 210 2 times, leaving a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 8878.87671232
The remainder is 64 after subtracting 146 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

After the division, we end up with 8878.87671232 and a remainder of 6.4e-08.
