65483818 ÷ 640 
The aim is to understand the frequency of 640 in 65483818.

Advancing 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
If we subtract 0 from 6, we get 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.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Take the next digit (4) from the dividend and append it to 65, then repeat: 654 / 640

Advancing to step 3:
If we divide 654 by 640, we get 1 and a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 640 away from 654, we end up with 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 640

Step 4:
When dividing 148 by 640, we get 0 with a remainder of 148.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 148, we get 148.
Take the next digit (3) from the dividend and append it to 148, then repeat: 1483 / 640

Step 5:
When dividing 1483 by 640, we get 2 with a remainder of 203.
Put 2 as the next digit of the answer. 
Result so far: 102.0
If we take 1280 away from 1483, we end up with 203.
Bring next digit (8) of the dividend behind the 203 and repeat the process: 2038 / 640

On to step 6:
When dividing 2038 by 640, we get 3 with a remainder of 118.
Write down 3 as next digit of the result. 
Result so far: 1023.0
If we subtract 1920 from 2038, we get 118.
Take the next digit (1) from the dividend and append it to 118, then repeat: 1181 / 640

Going ahead to step 7:
1181 divided by 640 is 1 with a remainder of 541.
Put 1 as the next digit of the answer. 
Result so far: 10231.0
Deduct 640 from 1181 and we're left with 541.
Include the next digit (8) from the dividend after 541, then repeat: 5418 / 640

Moving on to step 8:
5418 divided by 640 is 8 with a remainder of 298.
Use 8 as the next digit of our solution. 
Result so far: 102318.0
Deduct 5120 from 5418 and we're left with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Advancing to step 9:
640 goes into 2980 4 times with a remainder of 420.
Record the quotient 4 as the next digit in the result. 
Result so far: 102318.4
The remainder is 420 after subtracting 2560 from 2980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Let's proceed to step 10:
4200 divided by 640 is 6 with a remainder of 360.
Use 6 as the next digit of our solution. 
Result so far: 102318.46
If we take 3840 away from 4200, we end up 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.

Advancing to step 11:
The number 640 fits into 3600 5 times, leaving a remainder of 400.
The next digit of our result is 5. 
Result so far: 102318.465
Deduct 3200 from 3600 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Let's proceed to step 12:
640 can be fit into 4000 6 times, resulting in a remainder of 160.
The next digit of our result is 6. 
Result so far: 102318.4656
Subtract 3840 from 4000 to 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.

Step 13:
640 can be fit into 1600 2 times, resulting in a remainder of 320.
The number 2 becomes the next digit in our result. 
Result so far: 102318.46562
Subtract 1280 from 1600 to get 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 goes into 3200 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 102318.465625
Subtracting 3200 from 3200 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.

Going ahead 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: 102318.465625
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.

Moving on to step 16:
When dividing 0 by 640, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 102318.465625
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 quotient of the division is 102318.465625, and the remainder is 0.0.
