We look at the division of 820979 by 89 
The aim is to understand the frequency of 89 in 820979.

Going ahead to step 1:
8 divided by 89 is 0 with 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.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 89

Advancing to step 2:
89 can be fit into 82 0 times, resulting in a remainder of 82.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 82 to get 82.
Grab the next digit (0) from the dividend, add it to 82, then carry on: 820 / 89

Advancing to step 3:
The number 89 fits into 820 9 times, leaving a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 801 from 820, we get 19.
Grab the next digit (9) from the dividend, add it to 19, then carry on: 199 / 89

Step 4:
When dividing 199 by 89, we get 2 with a remainder of 21.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
Deduct 178 from 199 and we're left with 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 89

On to step 5:
If we divide 217 by 89, we get 2 and a remainder of 39.
Record the quotient 2 as the next digit in the result. 
Result so far: 922.0
If we take 178 away from 217, we end up with 39.
Grab the next digit (9) from the dividend, add it to 39, then carry on: 399 / 89

Step 6:
When dividing 399 by 89, we get 4 with a remainder of 43.
Record the quotient 4 as the next digit in the result. 
Result so far: 9224.0
If we subtract 356 from 399, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 7:
89 can be fit into 430 4 times, resulting in a remainder of 74.
Use 4 as the next digit of our solution. 
Result so far: 9224.4
If we subtract 356 from 430, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 8:
89 goes into 740 8 times with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 9224.48
Subtract 712 from 740 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 9:
The number 89 fits into 280 3 times, leaving a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 9224.483
Subtracting 267 from 280 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 10:
130 divided by 89 is 1 with a remainder of 41.
The next digit of our result is 1. 
Result so far: 9224.4831
If we take 89 away from 130, we end up 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.

Step 11:
89 can be fit into 410 4 times, resulting in a remainder of 54.
Put 4 as the next digit of the answer. 
Result so far: 9224.48314
Deduct 356 from 410 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 12:
89 goes into 540 6 times with a remainder of 6.
The next digit of our result is 6. 
Result so far: 9224.483146
Subtract 534 from 540 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 13:
89 can be fit into 60 0 times, resulting in a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 9224.483146
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 14:
600 divided by 89 is 6 with a remainder of 66.
The next digit of our result is 6. 
Result so far: 9224.48314606
Subtracting 534 from 600 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

After the division, we end up with 9224.48314606 and a remainder of 6.6e-08.
