Let's divide 63753557 by 640
The aim is to understand the frequency of 640 in 63753557.

Step 1:
640 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 640

On to step 2:
If we divide 63 by 640, we get 0 and a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Grab the next digit (7) from the dividend, add it to 63, then carry on: 637 / 640

Going ahead to step 3:
640 can be fit into 637 0 times, resulting in a remainder of 637.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 637 leaves us with 637.
Include the next digit (5) from the dividend after 637, then repeat: 6375 / 640

Moving on to step 4:
The number 640 fits into 6375 9 times, leaving a remainder of 615.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 5760 from 6375 to get 615.
Fetch the next digit (3) from the dividend, attach it to 615 and continue: 6153 / 640

Advancing to step 5:
640 goes into 6153 9 times with a remainder of 393.
Put 9 as the next digit of the answer. 
Result so far: 99.0
The remainder is 393 after subtracting 5760 from 6153.
Append the next digit (5) from the dividend to 393 and continue with: 3935 / 640

Moving on to step 6:
3935 divided by 640 is 6 with a remainder of 95.
The next digit of our result is 6. 
Result so far: 996.0
The remainder is 95 after subtracting 3840 from 3935.
Include the next digit (5) from the dividend after 95, then repeat: 955 / 640

Let's proceed to step 7:
955 divided by 640 is 1 with a remainder of 315.
The next digit of our result is 1. 
Result so far: 9961.0
Subtracting 640 from 955 leaves us with 315.
Fetch the next digit (7) from the dividend, attach it to 315 and continue: 3157 / 640

Step 8:
If we divide 3157 by 640, we get 4 and a remainder of 597.
The number 4 becomes the next digit in our result. 
Result so far: 99614.0
Subtracting 2560 from 3157 leaves us with 597.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5970, and continue the process.

Moving on to step 9:
5970 divided by 640 is 9 with a remainder of 210.
Put 9 as the next digit of the answer. 
Result so far: 99614.9
Subtracting 5760 from 5970 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Step 10:
640 goes into 2100 3 times with a remainder of 180.
The next digit of our result is 3. 
Result so far: 99614.93
Subtract 1920 from 2100 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 11:
If we divide 1800 by 640, we get 2 and a remainder of 520.
Use 2 as the next digit of our solution. 
Result so far: 99614.932
Subtracting 1280 from 1800 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 12:
If we divide 5200 by 640, we get 8 and a remainder of 80.
Put 8 as the next digit of the answer. 
Result so far: 99614.9328
If we take 5120 away from 5200, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 13:
If we divide 800 by 640, we get 1 and a remainder of 160.
Record the quotient 1 as the next digit in the result. 
Result so far: 99614.93281
Subtract 640 from 800 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.

Going ahead to step 14:
1600 divided by 640 is 2 with a remainder of 320.
Put 2 as the next digit of the answer. 
Result so far: 99614.932812
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 15:
640 can be fit into 3200 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 99614.9328125
If we subtract 3200 from 3200, we 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.

Moving on to step 16:
When dividing 0 by 640, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 99614.9328125
Deduct 0 from 0 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.

The final result is 99614.9328125 with a remainder of 0.0.
