We divide 86519 by 89
The aim is to understand the frequency of 89 in 86519.

Moving on to step 1:
If we divide 8 by 89, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 89

Going ahead to step 2:
If we divide 86 by 89, we get 0 and a remainder of 86.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Grab the next digit (5) from the dividend, add it to 86, then carry on: 865 / 89

Going ahead to step 3:
89 goes into 865 9 times with a remainder of 64.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 64 after subtracting 801 from 865.
Fetch the next digit (1) from the dividend, attach it to 64 and continue: 641 / 89

On to step 4:
The number 89 fits into 641 7 times, leaving a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
If we take 623 away from 641, we end up with 18.
Bring next digit (9) of the dividend behind the 18 and repeat the process: 189 / 89

On to step 5:
89 goes into 189 2 times with a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 972.0
Subtracting 178 from 189 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 6:
The number 89 fits into 110 1 times, leaving a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 972.1
Subtracting 89 from 110 leaves us with 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 7:
210 divided by 89 is 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 972.12
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 8:
320 divided by 89 is 3 with a remainder of 53.
The next digit of our result is 3. 
Result so far: 972.123
Subtract 267 from 320 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 9:
530 divided by 89 is 5 with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 972.1235
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 10:
If we divide 850 by 89, we get 9 and a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 972.12359
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.

Step 11:
The number 89 fits into 490 5 times, leaving a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 972.123595
Subtract 445 from 490 to 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.

Going ahead to step 12:
If we divide 450 by 89, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 972.1235955
The remainder is 5 after subtracting 445 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 972.1235955 with a remaining 5e-08.
