12015332 divided by 640 
Let's see how many times 640 fits into 12015332.

Step 1:
640 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 640

Step 2:
If we divide 12 by 640, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 640

Moving on to step 3:
The number 640 fits into 120 0 times, leaving a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 120, we end up with 120.
Take the next digit (1) from the dividend and append it to 120, then repeat: 1201 / 640

Advancing to step 4:
If we divide 1201 by 640, we get 1 and a remainder of 561.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 561 after subtracting 640 from 1201.
Take the next digit (5) from the dividend and append it to 561, then repeat: 5615 / 640

Moving on to step 5:
When dividing 5615 by 640, we get 8 with a remainder of 495.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we subtract 5120 from 5615, we get 495.
Grab the next digit (3) from the dividend, add it to 495, then carry on: 4953 / 640

On to step 6:
640 can be fit into 4953 7 times, resulting in a remainder of 473.
Use 7 as the next digit of our solution. 
Result so far: 187.0
Subtract 4480 from 4953 to get 473.
Grab the next digit (3) from the dividend, add it to 473, then carry on: 4733 / 640

On to step 7:
640 can be fit into 4733 7 times, resulting in a remainder of 253.
Use 7 as the next digit of our solution. 
Result so far: 1877.0
If we subtract 4480 from 4733, we get 253.
Fetch the next digit (2) from the dividend, attach it to 253 and continue: 2532 / 640

Advancing to step 8:
640 can be fit into 2532 3 times, resulting in a remainder of 612.
Use 3 as the next digit of our solution. 
Result so far: 18773.0
The remainder is 612 after subtracting 1920 from 2532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6120, and continue the process.

Advancing to step 9:
The number 640 fits into 6120 9 times, leaving a remainder of 360.
Record the quotient 9 as the next digit in the result. 
Result so far: 18773.9
If we take 5760 away from 6120, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Let's proceed to step 10:
640 can be fit into 3600 5 times, resulting in a remainder of 400.
Record the quotient 5 as the next digit in the result. 
Result so far: 18773.95
The remainder is 400 after subtracting 3200 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 11:
When dividing 4000 by 640, we get 6 with a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 18773.956
If we subtract 3840 from 4000, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 12:
The number 640 fits into 1600 2 times, leaving a remainder of 320.
Put 2 as the next digit of the answer. 
Result so far: 18773.9562
If we take 1280 away from 1600, we end up with 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

Going ahead to step 13:
The number 640 fits into 3200 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 18773.95625
Subtracting 3200 from 3200 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.

On to step 14:
The number 640 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18773.95625
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.

Let's proceed to step 15:
0 divided by 640 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 18773.95625
If we take 0 away from 0, we end up 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.

After the division, we end up with 18773.95625 and a remainder of 0.0.
