We look at the division of 802081 by 89 
The aim is to understand the frequency of 89 in 802081.

Advancing 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
If we subtract 0 from 8, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 89

On to step 2:
When dividing 80 by 89, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Grab the next digit (2) from the dividend, add it to 80, then carry on: 802 / 89

Let's proceed to step 3:
89 goes into 802 9 times with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 801 from 802 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 89

Moving on to step 4:
When dividing 10 by 89, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Subtract 0 from 10 to get 10.
Bring next digit (8) of the dividend behind the 10 and repeat the process: 108 / 89

Let's proceed to step 5:
89 goes into 108 1 times with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 901.0
The remainder is 19 after subtracting 89 from 108.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 89

Step 6:
When dividing 191 by 89, we get 2 with a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 9012.0
The remainder is 13 after subtracting 178 from 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
If we divide 130 by 89, we get 1 and a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 9012.1
The remainder is 41 after subtracting 89 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 8:
If we divide 410 by 89, we get 4 and a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 9012.14
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.

On to step 9:
The number 89 fits into 540 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 9012.146
The remainder is 6 after subtracting 534 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 10:
The number 89 fits into 60 0 times, leaving a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 9012.146
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 11:
89 goes into 600 6 times with a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 9012.14606
The remainder is 66 after subtracting 534 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 12:
89 goes into 660 7 times with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 9012.146067
If we take 623 away from 660, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 13:
The number 89 fits into 370 4 times, leaving a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 9012.1460674
Subtract 356 from 370 to 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.

Moving on to step 14:
89 can be fit into 140 1 times, resulting in a remainder of 51.
Write down 1 as next digit of the result. 
Result so far: 9012.14606741
Subtracting 89 from 140 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

After the division, we end up with 9012.14606741 and a remainder of 5.1e-08.
