639913 divided by 73 
We want to figure out the number of times 639913 can be divided by 73.

Moving on to step 1:
73 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 73

Going ahead to step 2:
73 goes into 63 0 times with a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Fetch the next digit (9) from the dividend, attach it to 63 and continue: 639 / 73

Advancing to step 3:
The number 73 fits into 639 8 times, leaving a remainder of 55.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 584 from 639 to get 55.
Include the next digit (9) from the dividend after 55, then repeat: 559 / 73

Going ahead to step 4:
If we divide 559 by 73, we get 7 and a remainder of 48.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Deduct 511 from 559 and we're left with 48.
Include the next digit (1) from the dividend after 48, then repeat: 481 / 73

Let's proceed to step 5:
If we divide 481 by 73, we get 6 and a remainder of 43.
Record the quotient 6 as the next digit in the result. 
Result so far: 876.0
Subtracting 438 from 481 leaves us with 43.
Include the next digit (3) from the dividend after 43, then repeat: 433 / 73

Step 6:
433 divided by 73 is 5 with a remainder of 68.
Record the quotient 5 as the next digit in the result. 
Result so far: 8765.0
Subtract 365 from 433 to 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.

On to step 7:
If we divide 680 by 73, we get 9 and a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 8765.9
If we subtract 657 from 680, we get 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 8:
The number 73 fits into 230 3 times, leaving a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 8765.93
Subtract 219 from 230 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
If we divide 110 by 73, we get 1 and a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 8765.931
The remainder is 37 after subtracting 73 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 10:
The number 73 fits into 370 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 8765.9315
Deduct 365 from 370 and we're left 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.

On to step 11:
When dividing 50 by 73, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 8765.9315
Subtracting 0 from 50 leaves us with 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 12:
500 divided by 73 is 6 with a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 8765.931506
Subtracting 438 from 500 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 13:
620 divided by 73 is 8 with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 8765.9315068
If we take 584 away from 620, we end up with 36.
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 14:
If we divide 360 by 73, we get 4 and a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 8765.93150684
Subtract 292 from 360 to 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.

Our division results in 8765.93150684 with a remaining 6.8e-08.
