We're dividing 76358833 by 129 
The aim is to understand the frequency of 129 in 76358833.

Going ahead to step 1:
129 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 129

Step 2:
The number 129 fits into 76 0 times, leaving a remainder of 76.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Include the next digit (3) from the dividend after 76, then repeat: 763 / 129

Moving on to step 3:
129 goes into 763 5 times with a remainder of 118.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtract 645 from 763 to get 118.
Take the next digit (5) from the dividend and append it to 118, then repeat: 1185 / 129

Advancing to step 4:
129 goes into 1185 9 times with a remainder of 24.
Record the quotient 9 as the next digit in the result. 
Result so far: 59.0
Subtract 1161 from 1185 to get 24.
Fetch the next digit (8) from the dividend, attach it to 24 and continue: 248 / 129

Let's proceed to step 5:
129 can be fit into 248 1 times, resulting in a remainder of 119.
Put 1 as the next digit of the answer. 
Result so far: 591.0
If we subtract 129 from 248, we get 119.
Grab the next digit (8) from the dividend, add it to 119, then carry on: 1198 / 129

On to step 6:
When dividing 1198 by 129, we get 9 with a remainder of 37.
The next digit of our result is 9. 
Result so far: 5919.0
If we take 1161 away from 1198, we end up with 37.
Include the next digit (3) from the dividend after 37, then repeat: 373 / 129

Step 7:
The number 129 fits into 373 2 times, leaving a remainder of 115.
Use 2 as the next digit of our solution. 
Result so far: 59192.0
If we take 258 away from 373, we end up with 115.
Fetch the next digit (3) from the dividend, attach it to 115 and continue: 1153 / 129

Moving on to step 8:
129 goes into 1153 8 times with a remainder of 121.
Put 8 as the next digit of the answer. 
Result so far: 591928.0
Subtracting 1032 from 1153 leaves us with 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Moving on to step 9:
1210 divided by 129 is 9 with a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 591928.9
If we take 1161 away from 1210, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 10:
129 can be fit into 490 3 times, resulting in a remainder of 103.
The next digit of our result is 3. 
Result so far: 591928.93
The remainder is 103 after subtracting 387 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

On to step 11:
When dividing 1030 by 129, we get 7 with a remainder of 127.
The number 7 becomes the next digit in our result. 
Result so far: 591928.937
Subtracting 903 from 1030 leaves us with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Going ahead to step 12:
129 goes into 1270 9 times with a remainder of 109.
Record the quotient 9 as the next digit in the result. 
Result so far: 591928.9379
Subtract 1161 from 1270 to 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.

Going ahead to step 13:
The number 129 fits into 1090 8 times, leaving a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 591928.93798
If we take 1032 away from 1090, we end up 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.

Moving on to step 14:
129 can be fit into 580 4 times, resulting in a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 591928.937984
Subtracting 516 from 580 leaves us 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.

On to step 15:
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: 591928.9379844
Subtracting 516 from 640 leaves us 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.

After the division, we end up with 591928.9379844 and a remainder of 1.24e-06.
