We look at the division of 852339 by 89 
The aim is to understand the frequency of 89 in 852339.

Going ahead to step 1:
The number 89 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 89

Let's proceed to step 2:
If we divide 85 by 89, we get 0 and a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Grab the next digit (2) from the dividend, add it to 85, then carry on: 852 / 89

Advancing to step 3:
89 can be fit into 852 9 times, resulting in a remainder of 51.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 801 from 852 to get 51.
Grab the next digit (3) from the dividend, add it to 51, then carry on: 513 / 89

Moving on to step 4:
If we divide 513 by 89, we get 5 and a remainder of 68.
Write down 5 as next digit of the result. 
Result so far: 95.0
If we take 445 away from 513, we end up with 68.
Append the next digit (3) from the dividend to 68 and continue with: 683 / 89

Advancing to step 5:
If we divide 683 by 89, we get 7 and a remainder of 60.
Use 7 as the next digit of our solution. 
Result so far: 957.0
If we subtract 623 from 683, we get 60.
Bring next digit (9) of the dividend behind the 60 and repeat the process: 609 / 89

Step 6:
89 goes into 609 6 times with a remainder of 75.
Use 6 as the next digit of our solution. 
Result so far: 9576.0
Deduct 534 from 609 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 7:
89 can be fit into 750 8 times, resulting in a remainder of 38.
The next digit of our result is 8. 
Result so far: 9576.8
If we subtract 712 from 750, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 8:
If we divide 380 by 89, we get 4 and a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 9576.84
Subtracting 356 from 380 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
89 can be fit into 240 2 times, resulting in a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 9576.842
The remainder is 62 after subtracting 178 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 10:
When dividing 620 by 89, we get 6 with a remainder of 86.
Record the quotient 6 as the next digit in the result. 
Result so far: 9576.8426
If we subtract 534 from 620, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 11:
The number 89 fits into 860 9 times, leaving a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 9576.84269
The remainder is 59 after subtracting 801 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 12:
89 goes into 590 6 times with a remainder of 56.
The next digit of our result is 6. 
Result so far: 9576.842696
If we subtract 534 from 590, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 13:
If we divide 560 by 89, we get 6 and a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 9576.8426966
Deduct 534 from 560 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 9576.8426966, with a leftover of 2.6e-07.
