Let's divide 57820432 by 640
Our goal is to divide 57820432 by 640.

Let's proceed to step 1:
640 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 640

Advancing to step 2:
640 goes into 57 0 times with a remainder of 57.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Take the next digit (8) from the dividend and append it to 57, then repeat: 578 / 640

Going ahead to step 3:
The number 640 fits into 578 0 times, leaving a remainder of 578.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 578, we get 578.
Take the next digit (2) from the dividend and append it to 578, then repeat: 5782 / 640

Advancing to step 4:
640 goes into 5782 9 times with a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 5760 from 5782, we get 22.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 640

Step 5:
220 divided by 640 is 0 with a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 90.0
Deduct 0 from 220 and we're left with 220.
Grab the next digit (4) from the dividend, add it to 220, then carry on: 2204 / 640

Moving on to step 6:
2204 divided by 640 is 3 with a remainder of 284.
Record the quotient 3 as the next digit in the result. 
Result so far: 903.0
If we take 1920 away from 2204, we end up with 284.
Take the next digit (3) from the dividend and append it to 284, then repeat: 2843 / 640

Going ahead to step 7:
If we divide 2843 by 640, we get 4 and a remainder of 283.
The next digit of our result is 4. 
Result so far: 9034.0
Deduct 2560 from 2843 and we're left with 283.
Bring next digit (2) of the dividend behind the 283 and repeat the process: 2832 / 640

Let's proceed to step 8:
2832 divided by 640 is 4 with a remainder of 272.
Record the quotient 4 as the next digit in the result. 
Result so far: 90344.0
If we subtract 2560 from 2832, we get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 9:
The number 640 fits into 2720 4 times, leaving a remainder of 160.
The number 4 becomes the next digit in our result. 
Result so far: 90344.4
If we subtract 2560 from 2720, 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.

Going ahead to step 10:
640 can be fit into 1600 2 times, resulting in a remainder of 320.
Record the quotient 2 as the next digit in the result. 
Result so far: 90344.42
Subtract 1280 from 1600 to 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.

Let's proceed to step 11:
The number 640 fits into 3200 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 90344.425
The remainder is 0 after subtracting 3200 from 3200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
The number 640 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 90344.425
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 13:
If we divide 0 by 640, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 90344.425
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.

The final result is 90344.425 with a remainder of 0.0.
