Let's divide 63404757 by 863
The aim is to understand the frequency of 863 in 63404757.

Advancing to step 1:
When dividing 6 by 863, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 863

Advancing to step 2:
863 goes into 63 0 times with a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Grab the next digit (4) from the dividend, add it to 63, then carry on: 634 / 863

On to step 3:
The number 863 fits into 634 0 times, leaving a remainder of 634.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 634 to get 634.
Take the next digit (0) from the dividend and append it to 634, then repeat: 6340 / 863

Step 4:
863 goes into 6340 7 times with a remainder of 299.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 6041 from 6340 to get 299.
Fetch the next digit (4) from the dividend, attach it to 299 and continue: 2994 / 863

Step 5:
863 goes into 2994 3 times with a remainder of 405.
The number 3 becomes the next digit in our result. 
Result so far: 73.0
If we subtract 2589 from 2994, we get 405.
Append the next digit (7) from the dividend to 405 and continue with: 4057 / 863

Advancing to step 6:
863 can be fit into 4057 4 times, resulting in a remainder of 605.
Write down 4 as next digit of the result. 
Result so far: 734.0
If we take 3452 away from 4057, we end up with 605.
Append the next digit (5) from the dividend to 605 and continue with: 6055 / 863

Advancing to step 7:
863 can be fit into 6055 7 times, resulting in a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 7347.0
The remainder is 14 after subtracting 6041 from 6055.
Grab the next digit (7) from the dividend, add it to 14, then carry on: 147 / 863

Advancing to step 8:
If we divide 147 by 863, we get 0 and a remainder of 147.
Record the quotient 0 as the next digit in the result. 
Result so far: 73470.0
Subtract 0 from 147 to get 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1470, and continue the process.

Step 9:
1470 divided by 863 is 1 with a remainder of 607.
Record the quotient 1 as the next digit in the result. 
Result so far: 73470.1
Deduct 863 from 1470 and we're left with 607.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6070, and continue the process.

Moving on to step 10:
863 goes into 6070 7 times with a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 73470.17
Subtract 6041 from 6070 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 11:
When dividing 290 by 863, we get 0 with a remainder of 290.
Record the quotient 0 as the next digit in the result. 
Result so far: 73470.17
Subtracting 0 from 290 leaves us with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 12:
863 goes into 2900 3 times with a remainder of 311.
Put 3 as the next digit of the answer. 
Result so far: 73470.1703
Subtracting 2589 from 2900 leaves us with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Advancing to step 13:
863 can be fit into 3110 3 times, resulting in a remainder of 521.
The number 3 becomes the next digit in our result. 
Result so far: 73470.17033
Subtracting 2589 from 3110 leaves us with 521.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5210, and continue the process.

In conclusion, the division gives 73470.17033 with a balance of 0.000521.
