We're dividing 488644 by 89 
The aim is to understand the frequency of 89 in 488644.

On to step 1:
When dividing 4 by 89, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 89

Going ahead to step 2:
89 can be fit into 48 0 times, resulting in a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Take the next digit (8) from the dividend and append it to 48, then repeat: 488 / 89

Going ahead to step 3:
488 divided by 89 is 5 with a remainder of 43.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 445 from 488 and we're left with 43.
Include the next digit (6) from the dividend after 43, then repeat: 436 / 89

Moving on to step 4:
89 goes into 436 4 times with a remainder of 80.
Put 4 as the next digit of the answer. 
Result so far: 54.0
If we subtract 356 from 436, we get 80.
Append the next digit (4) from the dividend to 80 and continue with: 804 / 89

Going ahead to step 5:
89 can be fit into 804 9 times, resulting in a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 549.0
The remainder is 3 after subtracting 801 from 804.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 89

Going ahead to step 6:
When dividing 34 by 89, we get 0 with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 5490.0
The remainder is 34 after subtracting 0 from 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
The number 89 fits into 340 3 times, leaving a remainder of 73.
The next digit of our result is 3. 
Result so far: 5490.3
If we take 267 away from 340, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

On to step 8:
89 can be fit into 730 8 times, resulting in a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 5490.38
The remainder is 18 after subtracting 712 from 730.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
89 goes into 180 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 5490.382
Subtract 178 from 180 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
When dividing 20 by 89, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 5490.382
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
If we divide 200 by 89, we get 2 and a remainder of 22.
Record the quotient 2 as the next digit in the result. 
Result so far: 5490.38202
If we take 178 away from 200, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 12:
If we divide 220 by 89, we get 2 and a remainder of 42.
Put 2 as the next digit of the answer. 
Result so far: 5490.382022
If we take 178 away from 220, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 5490.382022, with a leftover of 4.2e-06.
