We divide 45701615 by 640
We want to figure out the number of times 45701615 can be divided by 640.

Going ahead to step 1:
640 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
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

Moving on to step 2:
45 divided by 640 is 0 with a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 45 and we're left with 45.
Fetch the next digit (7) from the dividend, attach it to 45 and continue: 457 / 640

Moving on to step 3:
640 goes into 457 0 times with a remainder of 457.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 457 to get 457.
Grab the next digit (0) from the dividend, add it to 457, then carry on: 4570 / 640

Going ahead to step 4:
4570 divided by 640 is 7 with a remainder of 90.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 4480 away from 4570, we end up with 90.
Include the next digit (1) from the dividend after 90, then repeat: 901 / 640

Let's proceed to step 5:
640 can be fit into 901 1 times, resulting in a remainder of 261.
Use 1 as the next digit of our solution. 
Result so far: 71.0
The remainder is 261 after subtracting 640 from 901.
Fetch the next digit (6) from the dividend, attach it to 261 and continue: 2616 / 640

Moving on to step 6:
2616 divided by 640 is 4 with a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 714.0
Deduct 2560 from 2616 and we're left with 56.
Append the next digit (1) from the dividend to 56 and continue with: 561 / 640

Advancing to step 7:
When dividing 561 by 640, we get 0 with a remainder of 561.
The number 0 becomes the next digit in our result. 
Result so far: 7140.0
The remainder is 561 after subtracting 0 from 561.
Fetch the next digit (5) from the dividend, attach it to 561 and continue: 5615 / 640

Advancing to step 8:
640 can be fit into 5615 8 times, resulting in a remainder of 495.
Put 8 as the next digit of the answer. 
Result so far: 71408.0
Deduct 5120 from 5615 and we're left with 495.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4950, and continue the process.

On to step 9:
The number 640 fits into 4950 7 times, leaving a remainder of 470.
Put 7 as the next digit of the answer. 
Result so far: 71408.7
Subtracting 4480 from 4950 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Let's proceed to step 10:
4700 divided by 640 is 7 with a remainder of 220.
Record the quotient 7 as the next digit in the result. 
Result so far: 71408.77
The remainder is 220 after subtracting 4480 from 4700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

After the division, we end up with 71408.77 and a remainder of 0.22.
