89619320 divided by 129 
The aim is to understand the frequency of 129 in 89619320.

Let's proceed to step 1:
129 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 129

Advancing to step 2:
129 can be fit into 89 0 times, resulting in a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 89 and we're left with 89.
Fetch the next digit (6) from the dividend, attach it to 89 and continue: 896 / 129

Moving on to step 3:
When dividing 896 by 129, we get 6 with a remainder of 122.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 774 away from 896, we end up with 122.
Take the next digit (1) from the dividend and append it to 122, then repeat: 1221 / 129

Going ahead to step 4:
129 can be fit into 1221 9 times, resulting in a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
Deduct 1161 from 1221 and we're left with 60.
Bring next digit (9) of the dividend behind the 60 and repeat the process: 609 / 129

On to step 5:
The number 129 fits into 609 4 times, leaving a remainder of 93.
The number 4 becomes the next digit in our result. 
Result so far: 694.0
If we subtract 516 from 609, we get 93.
Include the next digit (3) from the dividend after 93, then repeat: 933 / 129

Step 6:
933 divided by 129 is 7 with a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 6947.0
Deduct 903 from 933 and we're left with 30.
Take the next digit (2) from the dividend and append it to 30, then repeat: 302 / 129

Moving on to step 7:
If we divide 302 by 129, we get 2 and a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 69472.0
The remainder is 44 after subtracting 258 from 302.
Take the next digit (0) from the dividend and append it to 44, then repeat: 440 / 129

On to step 8:
129 goes into 440 3 times with a remainder of 53.
Write down 3 as next digit of the result. 
Result so far: 694723.0
Subtracting 387 from 440 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 9:
When dividing 530 by 129, we get 4 with a remainder of 14.
Write down 4 as next digit of the result. 
Result so far: 694723.4
If we subtract 516 from 530, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
129 can be fit into 140 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 694723.41
Subtract 129 from 140 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 11:
129 goes into 110 0 times with a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 694723.41
Deduct 0 from 110 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 12:
When dividing 1100 by 129, we get 8 with a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 694723.4108
Subtract 1032 from 1100 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 13:
680 divided by 129 is 5 with a remainder of 35.
The next digit of our result is 5. 
Result so far: 694723.41085
Subtracting 645 from 680 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 14:
If we divide 350 by 129, we get 2 and a remainder of 92.
The number 2 becomes the next digit in our result. 
Result so far: 694723.410852
Deduct 258 from 350 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 15:
920 divided by 129 is 7 with a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 694723.4108527
If we take 903 away from 920, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 16:
When dividing 170 by 129, we get 1 with a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 694723.41085271
Deduct 129 from 170 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Our division results in 694723.41085271 with a remaining 4.1e-08.
