We're dividing 40500574 by 640 
The aim is to understand the frequency of 640 in 40500574.

Step 1:
The number 640 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 640

On to step 2:
40 divided by 640 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 640

Advancing to step 3:
405 divided by 640 is 0 with a remainder of 405.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 405 leaves us with 405.
Include the next digit (0) from the dividend after 405, then repeat: 4050 / 640

Advancing to step 4:
If we divide 4050 by 640, we get 6 and a remainder of 210.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 210 after subtracting 3840 from 4050.
Append the next digit (0) from the dividend to 210 and continue with: 2100 / 640

Going ahead to step 5:
The number 640 fits into 2100 3 times, leaving a remainder of 180.
Put 3 as the next digit of the answer. 
Result so far: 63.0
Subtract 1920 from 2100 to get 180.
Include the next digit (5) from the dividend after 180, then repeat: 1805 / 640

Let's proceed to step 6:
When dividing 1805 by 640, we get 2 with a remainder of 525.
The number 2 becomes the next digit in our result. 
Result so far: 632.0
If we take 1280 away from 1805, we end up with 525.
Take the next digit (7) from the dividend and append it to 525, then repeat: 5257 / 640

Step 7:
640 goes into 5257 8 times with a remainder of 137.
The number 8 becomes the next digit in our result. 
Result so far: 6328.0
Subtract 5120 from 5257 to get 137.
Fetch the next digit (4) from the dividend, attach it to 137 and continue: 1374 / 640

Moving on to step 8:
640 goes into 1374 2 times with a remainder of 94.
Write down 2 as next digit of the result. 
Result so far: 63282.0
The remainder is 94 after subtracting 1280 from 1374.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 9:
640 can be fit into 940 1 times, resulting in a remainder of 300.
Write down 1 as next digit of the result. 
Result so far: 63282.1
Deduct 640 from 940 and we're left with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Going ahead to step 10:
640 goes into 3000 4 times with a remainder of 440.
Use 4 as the next digit of our solution. 
Result so far: 63282.14
Deduct 2560 from 3000 and we're left with 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:
The number 640 fits into 4400 6 times, leaving a remainder of 560.
Record the quotient 6 as the next digit in the result. 
Result so far: 63282.146
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: 63282.1468
Subtract 5120 from 5600 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Going ahead to step 13:
The number 640 fits into 4800 7 times, leaving a remainder of 320.
Use 7 as the next digit of our solution. 
Result so far: 63282.14687
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.

Moving on to step 14:
640 can be fit into 3200 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 63282.146875
If we take 3200 away from 3200, 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.

Step 15:
640 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 63282.146875
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.

Step 16:
The number 640 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 63282.146875
Subtracting 0 from 0 leaves us 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.

In conclusion, the division gives 63282.146875 with a balance of 0.0.
