We divide 2988880 by 640
Let's see how many times 640 fits into 2988880.

Going ahead to step 1:
If we divide 2 by 640, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 640

Advancing to step 2:
640 goes into 29 0 times with a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Fetch the next digit (8) from the dividend, attach it to 29 and continue: 298 / 640

Going ahead to step 3:
When dividing 298 by 640, we get 0 with a remainder of 298.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 298 after subtracting 0 from 298.
Take the next digit (8) from the dividend and append it to 298, then repeat: 2988 / 640

On to step 4:
640 can be fit into 2988 4 times, resulting in a remainder of 428.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 2560 from 2988 leaves us with 428.
Include the next digit (8) from the dividend after 428, then repeat: 4288 / 640

Step 5:
640 can be fit into 4288 6 times, resulting in a remainder of 448.
Record the quotient 6 as the next digit in the result. 
Result so far: 46.0
Subtract 3840 from 4288 to get 448.
Append the next digit (8) from the dividend to 448 and continue with: 4488 / 640

Step 6:
The number 640 fits into 4488 7 times, leaving a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 467.0
Deduct 4480 from 4488 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 640

Advancing to step 7:
When dividing 80 by 640, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 4670.0
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 8:
When dividing 800 by 640, we get 1 with a remainder of 160.
Record the quotient 1 as the next digit in the result. 
Result so far: 4670.1
If we take 640 away from 800, we end up with 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 9:
If we divide 1600 by 640, we get 2 and a remainder of 320.
The next digit of our result is 2. 
Result so far: 4670.12
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.

Let's proceed to step 10:
If we divide 3200 by 640, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 4670.125
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.

Advancing to step 11:
If we divide 0 by 640, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4670.125
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.

Let's proceed to step 12:
If we divide 0 by 640, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4670.125
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.

After the division, we end up with 4670.125 and a remainder of 0.0.
