Let's divide 63492250 by 129
The aim is to understand the frequency of 129 in 63492250.

Advancing to step 1:
The number 129 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 129

On to step 2:
If we divide 63 by 129, we get 0 and a remainder of 63.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Bring next digit (4) of the dividend behind the 63 and repeat the process: 634 / 129

Going ahead to step 3:
The number 129 fits into 634 4 times, leaving a remainder of 118.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 516 away from 634, we end up with 118.
Fetch the next digit (9) from the dividend, attach it to 118 and continue: 1189 / 129

Step 4:
1189 divided by 129 is 9 with a remainder of 28.
Write down 9 as next digit of the result. 
Result so far: 49.0
If we take 1161 away from 1189, we end up with 28.
Take the next digit (2) from the dividend and append it to 28, then repeat: 282 / 129

Let's proceed to step 5:
282 divided by 129 is 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 492.0
Subtracting 258 from 282 leaves us with 24.
Include the next digit (2) from the dividend after 24, then repeat: 242 / 129

Going ahead to step 6:
If we divide 242 by 129, we get 1 and a remainder of 113.
The number 1 becomes the next digit in our result. 
Result so far: 4921.0
Subtracting 129 from 242 leaves us with 113.
Take the next digit (5) from the dividend and append it to 113, then repeat: 1135 / 129

Advancing to step 7:
129 can be fit into 1135 8 times, resulting in a remainder of 103.
The number 8 becomes the next digit in our result. 
Result so far: 49218.0
Deduct 1032 from 1135 and we're left with 103.
Append the next digit (0) from the dividend to 103 and continue with: 1030 / 129

Advancing to step 8:
129 goes into 1030 7 times with a remainder of 127.
Use 7 as the next digit of our solution. 
Result so far: 492187.0
If we subtract 903 from 1030, we get 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Moving on to step 9:
1270 divided by 129 is 9 with a remainder of 109.
Write down 9 as next digit of the result. 
Result so far: 492187.9
If we subtract 1161 from 1270, we get 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Let's proceed to step 10:
If we divide 1090 by 129, we get 8 and a remainder of 58.
Put 8 as the next digit of the answer. 
Result so far: 492187.98
Deduct 1032 from 1090 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 11:
The number 129 fits into 580 4 times, leaving a remainder of 64.
The next digit of our result is 4. 
Result so far: 492187.984
If we take 516 away from 580, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 12:
If we divide 640 by 129, we get 4 and a remainder of 124.
Record the quotient 4 as the next digit in the result. 
Result so far: 492187.9844
Deduct 516 from 640 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

The final outcome is 492187.9844, with a leftover of 0.00124.
