We look at the division of 136836 by 89 
The aim is to understand the frequency of 89 in 136836.

Advancing to step 1:
89 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 89

Step 2:
89 can be fit into 13 0 times, resulting in a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Grab the next digit (6) from the dividend, add it to 13, then carry on: 136 / 89

Going ahead to step 3:
If we divide 136 by 89, we get 1 and a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 89 from 136 leaves us with 47.
Bring next digit (8) of the dividend behind the 47 and repeat the process: 478 / 89

Going ahead to step 4:
89 goes into 478 5 times with a remainder of 33.
The number 5 becomes the next digit in our result. 
Result so far: 15.0
If we take 445 away from 478, we end up with 33.
Fetch the next digit (3) from the dividend, attach it to 33 and continue: 333 / 89

Let's proceed to step 5:
333 divided by 89 is 3 with a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 153.0
Deduct 267 from 333 and we're left with 66.
Append the next digit (6) from the dividend to 66 and continue with: 666 / 89

Moving on to step 6:
When dividing 666 by 89, we get 7 with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 1537.0
If we take 623 away from 666, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 7:
If we divide 430 by 89, we get 4 and a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 1537.4
Subtract 356 from 430 to 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.

Let's proceed to step 8:
89 can be fit into 740 8 times, resulting in a remainder of 28.
The next digit of our result is 8. 
Result so far: 1537.48
If we take 712 away from 740, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
89 can be fit into 280 3 times, resulting in a remainder of 13.
The next digit of our result is 3. 
Result so far: 1537.483
The remainder is 13 after subtracting 267 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 10:
89 can be fit into 130 1 times, resulting in a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 1537.4831
If we subtract 89 from 130, we get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 11:
89 can be fit into 410 4 times, resulting in a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 1537.48314
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.

On to step 12:
540 divided by 89 is 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 1537.483146
If we take 534 away from 540, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
The number 89 fits into 60 0 times, leaving a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 1537.483146
Deduct 0 from 60 and we're left 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.

Advancing to step 14:
600 divided by 89 is 6 with a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 1537.48314606
Subtract 534 from 600 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

The final outcome is 1537.48314606, with a leftover of 6.6e-08.
