Let's divide 61575002 by 129
The aim is to understand the frequency of 129 in 61575002.

Let's proceed to step 1:
6 divided by 129 is 0 with 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.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 129

Step 2:
129 goes into 61 0 times with a remainder of 61.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 61 after subtracting 0 from 61.
Take the next digit (5) from the dividend and append it to 61, then repeat: 615 / 129

Moving on to step 3:
129 goes into 615 4 times with a remainder of 99.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 516 from 615 leaves us with 99.
Include the next digit (7) from the dividend after 99, then repeat: 997 / 129

Going ahead to step 4:
If we divide 997 by 129, we get 7 and a remainder of 94.
The next digit of our result is 7. 
Result so far: 47.0
The remainder is 94 after subtracting 903 from 997.
Fetch the next digit (5) from the dividend, attach it to 94 and continue: 945 / 129

Moving on to step 5:
If we divide 945 by 129, we get 7 and a remainder of 42.
Use 7 as the next digit of our solution. 
Result so far: 477.0
Subtract 903 from 945 to get 42.
Append the next digit (0) from the dividend to 42 and continue with: 420 / 129

Let's proceed to step 6:
129 goes into 420 3 times with a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 4773.0
Deduct 387 from 420 and we're left with 33.
Fetch the next digit (0) from the dividend, attach it to 33 and continue: 330 / 129

Advancing to step 7:
When dividing 330 by 129, we get 2 with a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 47732.0
Deduct 258 from 330 and we're left with 72.
Take the next digit (2) from the dividend and append it to 72, then repeat: 722 / 129

Going ahead to step 8:
129 can be fit into 722 5 times, resulting in a remainder of 77.
The next digit of our result is 5. 
Result so far: 477325.0
Subtract 645 from 722 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 9:
When dividing 770 by 129, we get 5 with a remainder of 125.
The next digit of our result is 5. 
Result so far: 477325.5
Deduct 645 from 770 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 10:
129 goes into 1250 9 times with a remainder of 89.
Record the quotient 9 as the next digit in the result. 
Result so far: 477325.59
Subtract 1161 from 1250 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 11:
If we divide 890 by 129, we get 6 and a remainder of 116.
The number 6 becomes the next digit in our result. 
Result so far: 477325.596
The remainder is 116 after subtracting 774 from 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 12:
The number 129 fits into 1160 8 times, leaving a remainder of 128.
Write down 8 as next digit of the result. 
Result so far: 477325.5968
If we take 1032 away from 1160, we end up with 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Step 13:
1280 divided by 129 is 9 with a remainder of 119.
The next digit of our result is 9. 
Result so far: 477325.59689
If we take 1161 away from 1280, we end up with 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Advancing to step 14:
1190 divided by 129 is 9 with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 477325.596899
Subtracting 1161 from 1190 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final outcome is 477325.596899, with a leftover of 2.9e-06.
