We divide 65248618 by 640
The aim is to understand the frequency of 640 in 65248618.

Let's proceed to step 1:
6 divided by 640 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 640

Going ahead to step 2:
If we divide 65 by 640, we get 0 and a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Include the next digit (2) from the dividend after 65, then repeat: 652 / 640

Step 3:
640 goes into 652 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 640 from 652 to get 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 640

Let's proceed to step 4:
The number 640 fits into 124 0 times, leaving a remainder of 124.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 124 and we're left with 124.
Grab the next digit (8) from the dividend, add it to 124, then carry on: 1248 / 640

Moving on to step 5:
640 can be fit into 1248 1 times, resulting in a remainder of 608.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
If we subtract 640 from 1248, we get 608.
Append the next digit (6) from the dividend to 608 and continue with: 6086 / 640

Let's proceed to step 6:
640 goes into 6086 9 times with a remainder of 326.
The number 9 becomes the next digit in our result. 
Result so far: 1019.0
Subtract 5760 from 6086 to get 326.
Grab the next digit (1) from the dividend, add it to 326, then carry on: 3261 / 640

On to step 7:
When dividing 3261 by 640, we get 5 with a remainder of 61.
Write down 5 as next digit of the result. 
Result so far: 10195.0
Deduct 3200 from 3261 and we're left with 61.
Bring next digit (8) of the dividend behind the 61 and repeat the process: 618 / 640

Let's proceed to step 8:
618 divided by 640 is 0 with a remainder of 618.
The number 0 becomes the next digit in our result. 
Result so far: 101950.0
If we subtract 0 from 618, we get 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Going ahead to step 9:
If we divide 6180 by 640, we get 9 and a remainder of 420.
Use 9 as the next digit of our solution. 
Result so far: 101950.9
If we take 5760 away from 6180, we end up with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 10:
The number 640 fits into 4200 6 times, leaving a remainder of 360.
The number 6 becomes the next digit in our result. 
Result so far: 101950.96
Subtracting 3840 from 4200 leaves us with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 11:
When dividing 3600 by 640, we get 5 with a remainder of 400.
The next digit of our result is 5. 
Result so far: 101950.965
The remainder is 400 after subtracting 3200 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Advancing to step 12:
640 can be fit into 4000 6 times, resulting in a remainder of 160.
Put 6 as the next digit of the answer. 
Result so far: 101950.9656
If we subtract 3840 from 4000, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 13:
640 goes into 1600 2 times with a remainder of 320.
Write down 2 as next digit of the result. 
Result so far: 101950.96562
The remainder is 320 after subtracting 1280 from 1600.
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 14:
If we divide 3200 by 640, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 101950.965625
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:
If we divide 0 by 640, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 101950.965625
Subtract 0 from 0 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.

On to 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: 101950.965625
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.

The final outcome is 101950.965625, with a leftover of 0.0.
