We're dividing 63289995 by 640 
The aim is to understand the frequency of 640 in 63289995.

Advancing to step 1:
When dividing 6 by 640, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 640

Going ahead to step 2:
640 can be fit into 63 0 times, resulting in a remainder of 63.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 63, we end up with 63.
Take the next digit (2) from the dividend and append it to 63, then repeat: 632 / 640

Going ahead to step 3:
The number 640 fits into 632 0 times, leaving a remainder of 632.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 632, we get 632.
Take the next digit (8) from the dividend and append it to 632, then repeat: 6328 / 640

Step 4:
6328 divided by 640 is 9 with a remainder of 568.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 5760 from 6328 leaves us with 568.
Append the next digit (9) from the dividend to 568 and continue with: 5689 / 640

Step 5:
The number 640 fits into 5689 8 times, leaving a remainder of 569.
Put 8 as the next digit of the answer. 
Result so far: 98.0
Deduct 5120 from 5689 and we're left with 569.
Fetch the next digit (9) from the dividend, attach it to 569 and continue: 5699 / 640

Advancing to step 6:
5699 divided by 640 is 8 with a remainder of 579.
Write down 8 as next digit of the result. 
Result so far: 988.0
Deduct 5120 from 5699 and we're left with 579.
Append the next digit (9) from the dividend to 579 and continue with: 5799 / 640

On to step 7:
640 can be fit into 5799 9 times, resulting in a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 9889.0
If we take 5760 away from 5799, we end up with 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 640

Going ahead to step 8:
640 goes into 395 0 times with a remainder of 395.
Record the quotient 0 as the next digit in the result. 
Result so far: 98890.0
Subtracting 0 from 395 leaves us with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Going ahead to step 9:
When dividing 3950 by 640, we get 6 with a remainder of 110.
Record the quotient 6 as the next digit in the result. 
Result so far: 98890.6
Subtracting 3840 from 3950 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 10:
When dividing 1100 by 640, we get 1 with a remainder of 460.
Write down 1 as next digit of the result. 
Result so far: 98890.61
The remainder is 460 after subtracting 640 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Advancing to step 11:
640 goes into 4600 7 times with a remainder of 120.
Write down 7 as next digit of the result. 
Result so far: 98890.617
Subtract 4480 from 4600 to 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:
640 can be fit into 1200 1 times, resulting in a remainder of 560.
The next digit of our result is 1. 
Result so far: 98890.6171
If we subtract 640 from 1200, we 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.

Let's proceed to step 13:
640 goes into 5600 8 times with a remainder of 480.
Put 8 as the next digit of the answer. 
Result so far: 98890.61718
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 14:
When dividing 4800 by 640, we get 7 with a remainder of 320.
The number 7 becomes the next digit in our result. 
Result so far: 98890.617187
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:
640 goes into 3200 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 98890.6171875
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.

Moving on to step 16:
The number 640 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 98890.6171875
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.

Our division results in 98890.6171875 with a remaining 0.0.
