We look at the division of 645607 by 73 
Let's see how many times 73 fits into 645607.

Going ahead to step 1:
73 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 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.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Grab the next digit (5) from the dividend, add it to 64, then carry on: 645 / 73

Moving on to step 3:
If we divide 645 by 73, we get 8 and a remainder of 61.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtracting 584 from 645 leaves us with 61.
Append the next digit (6) from the dividend to 61 and continue with: 616 / 73

On to step 4:
If we divide 616 by 73, we get 8 and a remainder of 32.
The next digit of our result is 8. 
Result so far: 88.0
Subtract 584 from 616 to get 32.
Take the next digit (0) from the dividend and append it to 32, then repeat: 320 / 73

Advancing to step 5:
320 divided by 73 is 4 with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 884.0
Deduct 292 from 320 and we're left with 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 73

On to step 6:
If we divide 287 by 73, we get 3 and a remainder of 68.
The next digit of our result is 3. 
Result so far: 8843.0
Subtracting 219 from 287 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 7:
680 divided by 73 is 9 with a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 8843.9
If we take 657 away from 680, we end up 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.

On to step 8:
If we divide 230 by 73, we get 3 and a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 8843.93
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.

Going ahead to step 9:
When dividing 110 by 73, we get 1 with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 8843.931
If we subtract 73 from 110, we 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.

On to step 10:
73 can be fit into 370 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 8843.9315
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.

On to step 11:
If we divide 50 by 73, we get 0 and a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 8843.9315
If we take 0 away from 50, we end up 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.

Moving on to step 12:
The number 73 fits into 500 6 times, leaving a remainder of 62.
The next digit of our result is 6. 
Result so far: 8843.931506
Subtract 438 from 500 to 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.

Step 13:
When dividing 620 by 73, we get 8 with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 8843.9315068
Subtract 584 from 620 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 14:
When dividing 360 by 73, we get 4 with a remainder of 68.
Write down 4 as next digit of the result. 
Result so far: 8843.93150684
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.

In conclusion, the division gives 8843.93150684 with a balance of 6.8e-08.
