645728 divided by 73 
We want to divide 645728 by 73.

Going ahead to step 1:
When dividing 6 by 73, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 73

Let's proceed to step 2:
When dividing 64 by 73, we get 0 with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 64 to get 64.
Fetch the next digit (5) from the dividend, attach it to 64 and continue: 645 / 73

Moving on to step 3:
If we divide 645 by 73, we get 8 and a remainder of 61.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we take 584 away from 645, we end up with 61.
Grab the next digit (7) from the dividend, add it to 61, then carry on: 617 / 73

Advancing to step 4:
73 goes into 617 8 times with a remainder of 33.
Use 8 as the next digit of our solution. 
Result so far: 88.0
Deduct 584 from 617 and we're left with 33.
Bring next digit (2) of the dividend behind the 33 and repeat the process: 332 / 73

Moving on to step 5:
332 divided by 73 is 4 with a remainder of 40.
Put 4 as the next digit of the answer. 
Result so far: 884.0
Subtract 292 from 332 to get 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 73

Moving on to step 6:
If we divide 408 by 73, we get 5 and a remainder of 43.
Write down 5 as next digit of the result. 
Result so far: 8845.0
The remainder is 43 after subtracting 365 from 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 7:
When dividing 430 by 73, we get 5 with a remainder of 65.
Use 5 as the next digit of our solution. 
Result so far: 8845.5
Subtracting 365 from 430 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 8:
73 can be fit into 650 8 times, resulting in a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 8845.58
Subtract 584 from 650 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 9:
When dividing 660 by 73, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 8845.589
Subtracting 657 from 660 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
The number 73 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 8845.589
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 11:
If we divide 300 by 73, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 8845.58904
If we take 292 away from 300, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
The number 73 fits into 80 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 8845.589041
Subtracting 73 from 80 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 13:
The number 73 fits into 70 0 times, leaving a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 8845.589041
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 14:
73 goes into 700 9 times with a remainder of 43.
The next digit of our result is 9. 
Result so far: 8845.58904109
If we take 657 away from 700, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

The quotient of the division is 8845.58904109, and the remainder is 4.3e-08.
