79869703 ÷ 89 
The aim is to understand the frequency of 89 in 79869703.

On to step 1:
If we divide 7 by 89, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 89

Moving on to step 2:
When dividing 79 by 89, we get 0 with a remainder of 79.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 79 and we're left with 79.
Append the next digit (8) from the dividend to 79 and continue with: 798 / 89

On to step 3:
When dividing 798 by 89, we get 8 with a remainder of 86.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 712 from 798, we get 86.
Append the next digit (6) from the dividend to 86 and continue with: 866 / 89

Going ahead to step 4:
The number 89 fits into 866 9 times, leaving a remainder of 65.
Write down 9 as next digit of the result. 
Result so far: 89.0
The remainder is 65 after subtracting 801 from 866.
Bring next digit (9) of the dividend behind the 65 and repeat the process: 659 / 89

Going ahead to step 5:
89 can be fit into 659 7 times, resulting in a remainder of 36.
Record the quotient 7 as the next digit in the result. 
Result so far: 897.0
Subtracting 623 from 659 leaves us with 36.
Include the next digit (7) from the dividend after 36, then repeat: 367 / 89

Let's proceed to step 6:
367 divided by 89 is 4 with a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 8974.0
If we take 356 away from 367, we end up with 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 89

Advancing to step 7:
89 can be fit into 110 1 times, resulting in a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 89741.0
If we take 89 away from 110, we end up with 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 89

Step 8:
89 can be fit into 213 2 times, resulting in a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 897412.0
The remainder is 35 after subtracting 178 from 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 9:
350 divided by 89 is 3 with a remainder of 83.
The next digit of our result is 3. 
Result so far: 897412.3
Subtracting 267 from 350 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Going ahead to step 10:
When dividing 830 by 89, we get 9 with a remainder of 29.
Write down 9 as next digit of the result. 
Result so far: 897412.39
The remainder is 29 after subtracting 801 from 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 11:
When dividing 290 by 89, we get 3 with a remainder of 23.
The next digit of our result is 3. 
Result so far: 897412.393
The remainder is 23 after subtracting 267 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 12:
89 can be fit into 230 2 times, resulting in a remainder of 52.
Put 2 as the next digit of the answer. 
Result so far: 897412.3932
Deduct 178 from 230 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 13:
The number 89 fits into 520 5 times, leaving a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 897412.39325
If we subtract 445 from 520, we get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 14:
When dividing 750 by 89, we get 8 with a remainder of 38.
The next digit of our result is 8. 
Result so far: 897412.393258
Subtracting 712 from 750 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 15:
89 can be fit into 380 4 times, resulting in a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 897412.3932584
If we subtract 356 from 380, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 16:
If we divide 240 by 89, we get 2 and a remainder of 62.
The next digit of our result is 2. 
Result so far: 897412.39325842
If we take 178 away from 240, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

The final result is 897412.39325842 with a remainder of 6.2e-08.
