We're dividing 63638095 by 76 
The aim is to understand the frequency of 76 in 63638095.

Let's proceed to step 1:
The number 76 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 76

Step 2:
The number 76 fits into 63 0 times, leaving a remainder of 63.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 63 leaves us with 63.
Grab the next digit (6) from the dividend, add it to 63, then carry on: 636 / 76

Step 3:
If we divide 636 by 76, we get 8 and a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 608 from 636 to get 28.
Include the next digit (3) from the dividend after 28, then repeat: 283 / 76

Going ahead to step 4:
76 goes into 283 3 times with a remainder of 55.
Record the quotient 3 as the next digit in the result. 
Result so far: 83.0
Subtracting 228 from 283 leaves us with 55.
Bring next digit (8) of the dividend behind the 55 and repeat the process: 558 / 76

Moving on to step 5:
The number 76 fits into 558 7 times, leaving a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 837.0
Subtract 532 from 558 to get 26.
Grab the next digit (0) from the dividend, add it to 26, then carry on: 260 / 76

Advancing to step 6:
When dividing 260 by 76, we get 3 with a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 8373.0
The remainder is 32 after subtracting 228 from 260.
Bring next digit (9) of the dividend behind the 32 and repeat the process: 329 / 76

Going ahead to step 7:
329 divided by 76 is 4 with a remainder of 25.
Put 4 as the next digit of the answer. 
Result so far: 83734.0
If we subtract 304 from 329, we get 25.
Include the next digit (5) from the dividend after 25, then repeat: 255 / 76

On to step 8:
The number 76 fits into 255 3 times, leaving a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 837343.0
Deduct 228 from 255 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Going ahead to step 9:
When dividing 270 by 76, we get 3 with a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 837343.3
The remainder is 42 after subtracting 228 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 10:
420 divided by 76 is 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 837343.35
The remainder is 40 after subtracting 380 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 11:
If we divide 400 by 76, we get 5 and a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 837343.355
Subtracting 380 from 400 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 837343.355, with a leftover of 0.002.
