Let's divide 45430718 by 640
We're looking to find how many times 640 goes into 45430718.

On to step 1:
4 divided by 640 is 0 with 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

Going ahead to step 2:
640 goes into 45 0 times with a remainder of 45.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Bring next digit (4) of the dividend behind the 45 and repeat the process: 454 / 640

Going ahead to step 3:
The number 640 fits into 454 0 times, leaving a remainder of 454.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 454 after subtracting 0 from 454.
Fetch the next digit (3) from the dividend, attach it to 454 and continue: 4543 / 640

On to step 4:
When dividing 4543 by 640, we get 7 with a remainder of 63.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Deduct 4480 from 4543 and we're left with 63.
Grab the next digit (0) from the dividend, add it to 63, then carry on: 630 / 640

Advancing to step 5:
640 can be fit into 630 0 times, resulting in a remainder of 630.
Use 0 as the next digit of our solution. 
Result so far: 70.0
Deduct 0 from 630 and we're left with 630.
Include the next digit (7) from the dividend after 630, then repeat: 6307 / 640

On to step 6:
6307 divided by 640 is 9 with a remainder of 547.
Record the quotient 9 as the next digit in the result. 
Result so far: 709.0
Subtract 5760 from 6307 to get 547.
Bring next digit (1) of the dividend behind the 547 and repeat the process: 5471 / 640

Advancing to step 7:
5471 divided by 640 is 8 with a remainder of 351.
The next digit of our result is 8. 
Result so far: 7098.0
Deduct 5120 from 5471 and we're left with 351.
Take the next digit (8) from the dividend and append it to 351, then repeat: 3518 / 640

Moving on to step 8:
The number 640 fits into 3518 5 times, leaving a remainder of 318.
Put 5 as the next digit of the answer. 
Result so far: 70985.0
If we take 3200 away from 3518, we end up with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

Advancing to step 9:
3180 divided by 640 is 4 with a remainder of 620.
Record the quotient 4 as the next digit in the result. 
Result so far: 70985.4
The remainder is 620 after subtracting 2560 from 3180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 10:
When dividing 6200 by 640, we get 9 with a remainder of 440.
Record the quotient 9 as the next digit in the result. 
Result so far: 70985.49
If we subtract 5760 from 6200, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 11:
When dividing 4400 by 640, we get 6 with a remainder of 560.
Use 6 as the next digit of our solution. 
Result so far: 70985.496
If we take 3840 away from 4400, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 12:
When dividing 5600 by 640, we get 8 with a remainder of 480.
Write down 8 as next digit of the result. 
Result so far: 70985.4968
If we take 5120 away from 5600, 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.

Advancing to step 13:
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: 70985.49687
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 14:
If we divide 3200 by 640, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 70985.496875
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.

Let's proceed to step 15:
0 divided by 640 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 70985.496875
If we take 0 away from 0, we end up 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.

Let's proceed to step 16:
640 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 70985.496875
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 70985.496875 with a balance of 0.0.
