64056475 ÷ 640 
We want to figure out the number of times 64056475 can be divided by 640.

On to step 1:
640 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 640

Step 2:
640 goes into 64 0 times with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 640

Step 3:
640 divided by 640 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 640 from 640 leaves us with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 640

Step 4:
640 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 640

Let's proceed to step 5:
If we divide 56 by 640, we get 0 and a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 100.0
Subtract 0 from 56 to get 56.
Append the next digit (4) from the dividend to 56 and continue with: 564 / 640

Moving on to step 6:
640 goes into 564 0 times with a remainder of 564.
The number 0 becomes the next digit in our result. 
Result so far: 1000.0
If we subtract 0 from 564, we get 564.
Bring next digit (7) of the dividend behind the 564 and repeat the process: 5647 / 640

Going ahead to step 7:
If we divide 5647 by 640, we get 8 and a remainder of 527.
The number 8 becomes the next digit in our result. 
Result so far: 10008.0
Subtracting 5120 from 5647 leaves us with 527.
Append the next digit (5) from the dividend to 527 and continue with: 5275 / 640

Step 8:
The number 640 fits into 5275 8 times, leaving a remainder of 155.
The next digit of our result is 8. 
Result so far: 100088.0
If we subtract 5120 from 5275, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 9:
1550 divided by 640 is 2 with a remainder of 270.
Put 2 as the next digit of the answer. 
Result so far: 100088.2
If we subtract 1280 from 1550, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 10:
2700 divided by 640 is 4 with a remainder of 140.
Write down 4 as next digit of the result. 
Result so far: 100088.24
Subtract 2560 from 2700 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 11:
When dividing 1400 by 640, we get 2 with a remainder of 120.
Record the quotient 2 as the next digit in the result. 
Result so far: 100088.242
If we subtract 1280 from 1400, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
The number 640 fits into 1200 1 times, leaving a remainder of 560.
The next digit of our result is 1. 
Result so far: 100088.2421
Subtract 640 from 1200 to get 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 13:
When dividing 5600 by 640, we get 8 with a remainder of 480.
The next digit of our result is 8. 
Result so far: 100088.24218
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.

Let's proceed to step 14:
640 can be fit into 4800 7 times, resulting in a remainder of 320.
Write down 7 as next digit of the result. 
Result so far: 100088.242187
If we take 4480 away from 4800, we end up 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.

Going ahead to step 15:
The number 640 fits into 3200 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 100088.2421875
Deduct 3200 from 3200 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.

Moving on to step 16:
The number 640 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 100088.2421875
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.

Our division results in 100088.2421875 with a remaining 0.0.
