Let's divide 73321907 by 129
The aim is to understand the frequency of 129 in 73321907.

Going ahead to step 1:
The number 129 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 129

Going ahead to step 2:
The number 129 fits into 73 0 times, leaving a remainder of 73.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Fetch the next digit (3) from the dividend, attach it to 73 and continue: 733 / 129

Moving on to step 3:
129 can be fit into 733 5 times, resulting in a remainder of 88.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 88 after subtracting 645 from 733.
Take the next digit (2) from the dividend and append it to 88, then repeat: 882 / 129

Let's proceed to step 4:
If we divide 882 by 129, we get 6 and a remainder of 108.
The next digit of our result is 6. 
Result so far: 56.0
If we subtract 774 from 882, we get 108.
Append the next digit (1) from the dividend to 108 and continue with: 1081 / 129

Let's proceed to step 5:
The number 129 fits into 1081 8 times, leaving a remainder of 49.
Put 8 as the next digit of the answer. 
Result so far: 568.0
If we take 1032 away from 1081, we end up with 49.
Take the next digit (9) from the dividend and append it to 49, then repeat: 499 / 129

On to step 6:
129 can be fit into 499 3 times, resulting in a remainder of 112.
Put 3 as the next digit of the answer. 
Result so far: 5683.0
If we subtract 387 from 499, we get 112.
Grab the next digit (0) from the dividend, add it to 112, then carry on: 1120 / 129

Let's proceed to step 7:
129 goes into 1120 8 times with a remainder of 88.
Record the quotient 8 as the next digit in the result. 
Result so far: 56838.0
Subtracting 1032 from 1120 leaves us with 88.
Take the next digit (7) from the dividend and append it to 88, then repeat: 887 / 129

Step 8:
129 can be fit into 887 6 times, resulting in a remainder of 113.
Write down 6 as next digit of the result. 
Result so far: 568386.0
If we take 774 away from 887, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Step 9:
129 goes into 1130 8 times with a remainder of 98.
The number 8 becomes the next digit in our result. 
Result so far: 568386.8
If we take 1032 away from 1130, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Step 10:
129 can be fit into 980 7 times, resulting in a remainder of 77.
Write down 7 as next digit of the result. 
Result so far: 568386.87
The remainder is 77 after subtracting 903 from 980.
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 11:
770 divided by 129 is 5 with a remainder of 125.
Put 5 as the next digit of the answer. 
Result so far: 568386.875
Subtract 645 from 770 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 12:
When dividing 1250 by 129, we get 9 with a remainder of 89.
Use 9 as the next digit of our solution. 
Result so far: 568386.8759
If we subtract 1161 from 1250, we 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.

Moving on to step 13:
If we divide 890 by 129, we get 6 and a remainder of 116.
Use 6 as the next digit of our solution. 
Result so far: 568386.87596
If we take 774 away from 890, we end up with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 14:
When dividing 1160 by 129, we get 8 with a remainder of 128.
Record the quotient 8 as the next digit in the result. 
Result so far: 568386.875968
Subtracting 1032 from 1160 leaves us 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.

On to step 15:
1280 divided by 129 is 9 with a remainder of 119.
The next digit of our result is 9. 
Result so far: 568386.8759689
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.

Moving on to step 16:
129 goes into 1190 9 times with a remainder of 29.
The number 9 becomes the next digit in our result. 
Result so far: 568386.87596899
The remainder is 29 after subtracting 1161 from 1190.
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 result is 568386.87596899 with a remainder of 2.9e-08.
