We're dividing 9439312 by 640 
Our goal is to divide 9439312 by 640.

Going ahead to step 1:
If we divide 9 by 640, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 640

Advancing to step 2:
94 divided by 640 is 0 with a remainder of 94.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 94, we get 94.
Fetch the next digit (3) from the dividend, attach it to 94 and continue: 943 / 640

Step 3:
If we divide 943 by 640, we get 1 and a remainder of 303.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 640 from 943 to get 303.
Fetch the next digit (9) from the dividend, attach it to 303 and continue: 3039 / 640

Moving on to step 4:
640 can be fit into 3039 4 times, resulting in a remainder of 479.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 479 after subtracting 2560 from 3039.
Fetch the next digit (3) from the dividend, attach it to 479 and continue: 4793 / 640

Let's proceed to step 5:
640 can be fit into 4793 7 times, resulting in a remainder of 313.
The number 7 becomes the next digit in our result. 
Result so far: 147.0
The remainder is 313 after subtracting 4480 from 4793.
Append the next digit (1) from the dividend to 313 and continue with: 3131 / 640

Going ahead to step 6:
3131 divided by 640 is 4 with a remainder of 571.
Use 4 as the next digit of our solution. 
Result so far: 1474.0
If we subtract 2560 from 3131, we get 571.
Append the next digit (2) from the dividend to 571 and continue with: 5712 / 640

Moving on to step 7:
The number 640 fits into 5712 8 times, leaving a remainder of 592.
Put 8 as the next digit of the answer. 
Result so far: 14748.0
Deduct 5120 from 5712 and we're left with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

On to step 8:
640 can be fit into 5920 9 times, resulting in a remainder of 160.
Use 9 as the next digit of our solution. 
Result so far: 14748.9
The remainder is 160 after subtracting 5760 from 5920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 9:
The number 640 fits into 1600 2 times, leaving a remainder of 320.
Write down 2 as next digit of the result. 
Result so far: 14748.92
If we subtract 1280 from 1600, we get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Moving on to step 10:
640 goes into 3200 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 14748.925
Subtract 3200 from 3200 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
640 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 14748.925
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
0 divided by 640 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 14748.925
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 14748.925 with a balance of 0.0.
