We divide 45577935 by 640
We want to figure out the number of times 45577935 can be divided by 640.

Let's proceed to step 1:
The number 640 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 640

Let's proceed to step 2:
The number 640 fits into 45 0 times, leaving a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Grab the next digit (5) from the dividend, add it to 45, then carry on: 455 / 640

Let's proceed to step 3:
455 divided by 640 is 0 with a remainder of 455.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 455 after subtracting 0 from 455.
Bring next digit (7) of the dividend behind the 455 and repeat the process: 4557 / 640

Let's proceed to step 4:
640 goes into 4557 7 times with a remainder of 77.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtracting 4480 from 4557 leaves us with 77.
Grab the next digit (7) from the dividend, add it to 77, then carry on: 777 / 640

On to step 5:
640 goes into 777 1 times with a remainder of 137.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
Subtract 640 from 777 to get 137.
Fetch the next digit (9) from the dividend, attach it to 137 and continue: 1379 / 640

Step 6:
640 goes into 1379 2 times with a remainder of 99.
The next digit of our result is 2. 
Result so far: 712.0
The remainder is 99 after subtracting 1280 from 1379.
Include the next digit (3) from the dividend after 99, then repeat: 993 / 640

Let's proceed to step 7:
640 goes into 993 1 times with a remainder of 353.
Record the quotient 1 as the next digit in the result. 
Result so far: 7121.0
Subtract 640 from 993 to get 353.
Fetch the next digit (5) from the dividend, attach it to 353 and continue: 3535 / 640

Going ahead to step 8:
640 goes into 3535 5 times with a remainder of 335.
Record the quotient 5 as the next digit in the result. 
Result so far: 71215.0
If we subtract 3200 from 3535, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Going ahead to step 9:
640 can be fit into 3350 5 times, resulting in a remainder of 150.
Record the quotient 5 as the next digit in the result. 
Result so far: 71215.5
Deduct 3200 from 3350 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Step 10:
If we divide 1500 by 640, we get 2 and a remainder of 220.
Write down 2 as next digit of the result. 
Result so far: 71215.52
If we subtract 1280 from 1500, we get 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Step 11:
The number 640 fits into 2200 3 times, leaving a remainder of 280.
Put 3 as the next digit of the answer. 
Result so far: 71215.523
Subtracting 1920 from 2200 leaves us with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Going ahead to step 12:
640 can be fit into 2800 4 times, resulting in a remainder of 240.
Put 4 as the next digit of the answer. 
Result so far: 71215.5234
Subtracting 2560 from 2800 leaves us with 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

On to step 13:
2400 divided by 640 is 3 with a remainder of 480.
Record the quotient 3 as the next digit in the result. 
Result so far: 71215.52343
Deduct 1920 from 2400 and we're left 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.

Step 14:
The number 640 fits into 4800 7 times, leaving a remainder of 320.
Record the quotient 7 as the next digit in the result. 
Result so far: 71215.523437
Deduct 4480 from 4800 and we're left 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 15:
640 can be fit into 3200 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 71215.5234375
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.

Advancing to step 16:
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: 71215.5234375
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 final outcome is 71215.5234375, with a leftover of 0.0.
