We look at the division of 640698 by 73 
Our goal is to divide 640698 by 73.

On to step 1:
73 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 73

Let's proceed to step 2:
If we divide 64 by 73, we get 0 and a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 73

On to step 3:
When dividing 640 by 73, we get 8 with a remainder of 56.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 584 from 640 to get 56.
Grab the next digit (6) from the dividend, add it to 56, then carry on: 566 / 73

On to step 4:
566 divided by 73 is 7 with a remainder of 55.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Subtract 511 from 566 to get 55.
Grab the next digit (9) from the dividend, add it to 55, then carry on: 559 / 73

Step 5:
If we divide 559 by 73, we get 7 and a remainder of 48.
The next digit of our result is 7. 
Result so far: 877.0
Deduct 511 from 559 and we're left with 48.
Fetch the next digit (8) from the dividend, attach it to 48 and continue: 488 / 73

Moving on to step 6:
488 divided by 73 is 6 with a remainder of 50.
Record the quotient 6 as the next digit in the result. 
Result so far: 8776.0
The remainder is 50 after subtracting 438 from 488.
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 7:
73 goes into 500 6 times with a remainder of 62.
Record the quotient 6 as the next digit in the result. 
Result so far: 8776.6
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.

Moving on to step 8:
73 can be fit into 620 8 times, resulting in a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 8776.68
The remainder is 36 after subtracting 584 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
360 divided by 73 is 4 with a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 8776.684
The remainder is 68 after subtracting 292 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 10:
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: 8776.6849
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.

Step 11:
73 can be fit into 230 3 times, resulting in a remainder of 11.
The next digit of our result is 3. 
Result so far: 8776.68493
Deduct 219 from 230 and we're left 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.

Let's proceed to step 12:
73 can be fit into 110 1 times, resulting in a remainder of 37.
Write down 1 as next digit of the result. 
Result so far: 8776.684931
Subtract 73 from 110 to get 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 13:
When dividing 370 by 73, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 8776.6849315
If we take 365 away from 370, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 14:
73 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 8776.6849315
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 8776.6849315, with a leftover of 5e-08.
