Let's divide 57884471 by 640
We're looking to find how many times 640 goes into 57884471.

Moving on to step 1:
If we divide 5 by 640, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 640

Let's proceed to step 2:
57 divided by 640 is 0 with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Bring next digit (8) of the dividend behind the 57 and repeat the process: 578 / 640

Moving on to step 3:
640 can be fit into 578 0 times, resulting in a remainder of 578.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 578, we get 578.
Bring next digit (8) of the dividend behind the 578 and repeat the process: 5788 / 640

Let's proceed to step 4:
If we divide 5788 by 640, we get 9 and a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 28 after subtracting 5760 from 5788.
Bring next digit (4) of the dividend behind the 28 and repeat the process: 284 / 640

Advancing to step 5:
640 can be fit into 284 0 times, resulting in a remainder of 284.
Write down 0 as next digit of the result. 
Result so far: 90.0
If we take 0 away from 284, we end up with 284.
Grab the next digit (4) from the dividend, add it to 284, then carry on: 2844 / 640

Going ahead to step 6:
When dividing 2844 by 640, we get 4 with a remainder of 284.
Put 4 as the next digit of the answer. 
Result so far: 904.0
Subtract 2560 from 2844 to get 284.
Fetch the next digit (7) from the dividend, attach it to 284 and continue: 2847 / 640

On to step 7:
640 goes into 2847 4 times with a remainder of 287.
The number 4 becomes the next digit in our result. 
Result so far: 9044.0
Subtract 2560 from 2847 to get 287.
Bring next digit (1) of the dividend behind the 287 and repeat the process: 2871 / 640

Step 8:
The number 640 fits into 2871 4 times, leaving a remainder of 311.
Use 4 as the next digit of our solution. 
Result so far: 90444.0
If we take 2560 away from 2871, we end up with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Advancing to step 9:
640 goes into 3110 4 times with a remainder of 550.
The next digit of our result is 4. 
Result so far: 90444.4
Subtracting 2560 from 3110 leaves us with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 10:
640 can be fit into 5500 8 times, resulting in a remainder of 380.
The number 8 becomes the next digit in our result. 
Result so far: 90444.48
If we subtract 5120 from 5500, we get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Advancing to step 11:
640 goes into 3800 5 times with a remainder of 600.
Put 5 as the next digit of the answer. 
Result so far: 90444.485
If we take 3200 away from 3800, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 12:
640 can be fit into 6000 9 times, resulting in a remainder of 240.
Write down 9 as next digit of the result. 
Result so far: 90444.4859
The remainder is 240 after subtracting 5760 from 6000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Moving on to step 13:
The number 640 fits into 2400 3 times, leaving a remainder of 480.
The number 3 becomes the next digit in our result. 
Result so far: 90444.48593
If we take 1920 away from 2400, we end up with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 14:
If we divide 4800 by 640, we get 7 and a remainder of 320.
The number 7 becomes the next digit in our result. 
Result so far: 90444.485937
Subtracting 4480 from 4800 leaves us 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.

Moving on to step 15:
The number 640 fits into 3200 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 90444.4859375
If we subtract 3200 from 3200, 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.

On to step 16:
The number 640 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 90444.4859375
Deduct 0 from 0 and we're left 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.

The quotient of the division is 90444.4859375, and the remainder is 0.0.
