129951 ÷ 89 
The aim is to understand the frequency of 89 in 129951.

Going ahead to step 1:
89 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 89

Moving on to step 2:
The number 89 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Bring next digit (9) of the dividend behind the 12 and repeat the process: 129 / 89

Moving on to step 3:
When dividing 129 by 89, we get 1 with a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 40 after subtracting 89 from 129.
Grab the next digit (9) from the dividend, add it to 40, then carry on: 409 / 89

Let's proceed to step 4:
89 can be fit into 409 4 times, resulting in a remainder of 53.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
The remainder is 53 after subtracting 356 from 409.
Append the next digit (5) from the dividend to 53 and continue with: 535 / 89

Going ahead to step 5:
If we divide 535 by 89, we get 6 and a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 146.0
The remainder is 1 after subtracting 534 from 535.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 89

Step 6:
The number 89 fits into 11 0 times, leaving a remainder of 11.
The next digit of our result is 0. 
Result so far: 1460.0
The remainder is 11 after subtracting 0 from 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
When dividing 110 by 89, we get 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1460.1
If we subtract 89 from 110, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 8:
When dividing 210 by 89, we get 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 1460.12
Subtract 178 from 210 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 9:
320 divided by 89 is 3 with a remainder of 53.
The number 3 becomes the next digit in our result. 
Result so far: 1460.123
The remainder is 53 after subtracting 267 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 10:
When dividing 530 by 89, we get 5 with a remainder of 85.
The next digit of our result is 5. 
Result so far: 1460.1235
If we subtract 445 from 530, we get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 11:
The number 89 fits into 850 9 times, leaving a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 1460.12359
Deduct 801 from 850 and we're left 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.

Moving on to step 12:
If we divide 490 by 89, we get 5 and a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 1460.123595
If we subtract 445 from 490, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 13:
When dividing 450 by 89, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 1460.1235955
If we subtract 445 from 450, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 1460.1235955 with a remainder of 5e-08.
