We divide 886902 by 89
The aim is to understand the frequency of 89 in 886902.

Step 1:
If we divide 8 by 89, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 89

On to step 2:
If we divide 88 by 89, we get 0 and a remainder of 88.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 88 leaves us with 88.
Bring next digit (6) of the dividend behind the 88 and repeat the process: 886 / 89

On to step 3:
If we divide 886 by 89, we get 9 and a remainder of 85.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 85 after subtracting 801 from 886.
Take the next digit (9) from the dividend and append it to 85, then repeat: 859 / 89

Going ahead to step 4:
859 divided by 89 is 9 with a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 99.0
If we take 801 away from 859, we end up with 58.
Include the next digit (0) from the dividend after 58, then repeat: 580 / 89

Going ahead to step 5:
The number 89 fits into 580 6 times, leaving a remainder of 46.
Use 6 as the next digit of our solution. 
Result so far: 996.0
Deduct 534 from 580 and we're left with 46.
Bring next digit (2) of the dividend behind the 46 and repeat the process: 462 / 89

Moving on to step 6:
462 divided by 89 is 5 with a remainder of 17.
The number 5 becomes the next digit in our result. 
Result so far: 9965.0
Subtract 445 from 462 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
If we divide 170 by 89, we get 1 and a remainder of 81.
Write down 1 as next digit of the result. 
Result so far: 9965.1
If we take 89 away from 170, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 8:
If we divide 810 by 89, we get 9 and a remainder of 9.
The next digit of our result is 9. 
Result so far: 9965.19
The remainder is 9 after subtracting 801 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
When dividing 90 by 89, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 9965.191
If we take 89 away from 90, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 10:
10 divided by 89 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 9965.191
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
If we divide 100 by 89, we get 1 and a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 9965.19101
If we subtract 89 from 100, we 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.

Let's proceed to step 12:
If we divide 110 by 89, we get 1 and a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 9965.191011
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.

The final outcome is 9965.191011, with a leftover of 2.1e-06.
