We're dividing 73495604 by 640 
We want to divide 73495604 by 640.

Going ahead to step 1:
If we divide 7 by 640, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 640

Going ahead to step 2:
73 divided by 640 is 0 with a remainder of 73.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 73 and we're left with 73.
Append the next digit (4) from the dividend to 73 and continue with: 734 / 640

Step 3:
If we divide 734 by 640, we get 1 and a remainder of 94.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 94 after subtracting 640 from 734.
Include the next digit (9) from the dividend after 94, then repeat: 949 / 640

Advancing to step 4:
The number 640 fits into 949 1 times, leaving a remainder of 309.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 640 from 949 leaves us with 309.
Bring next digit (5) of the dividend behind the 309 and repeat the process: 3095 / 640

Advancing to step 5:
640 goes into 3095 4 times with a remainder of 535.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
Subtract 2560 from 3095 to get 535.
Take the next digit (6) from the dividend and append it to 535, then repeat: 5356 / 640

Step 6:
When dividing 5356 by 640, we get 8 with a remainder of 236.
The number 8 becomes the next digit in our result. 
Result so far: 1148.0
The remainder is 236 after subtracting 5120 from 5356.
Fetch the next digit (0) from the dividend, attach it to 236 and continue: 2360 / 640

Let's proceed to step 7:
2360 divided by 640 is 3 with a remainder of 440.
The number 3 becomes the next digit in our result. 
Result so far: 11483.0
Subtract 1920 from 2360 to get 440.
Take the next digit (4) from the dividend and append it to 440, then repeat: 4404 / 640

Let's proceed to step 8:
When dividing 4404 by 640, we get 6 with a remainder of 564.
Write down 6 as next digit of the result. 
Result so far: 114836.0
If we take 3840 away from 4404, we end up with 564.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5640, and continue the process.

Step 9:
The number 640 fits into 5640 8 times, leaving a remainder of 520.
Put 8 as the next digit of the answer. 
Result so far: 114836.8
If we take 5120 away from 5640, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Moving on to step 10:
640 can be fit into 5200 8 times, resulting in a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 114836.88
If we subtract 5120 from 5200, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

In conclusion, the division gives 114836.88 with a balance of 0.08.
