Let's divide 88647789 by 490
The aim is to understand the frequency of 490 in 88647789.

Advancing to step 1:
490 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 490

Let's proceed to step 2:
88 divided by 490 is 0 with a remainder of 88.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 88, we end up with 88.
Include the next digit (6) from the dividend after 88, then repeat: 886 / 490

Going ahead to step 3:
490 can be fit into 886 1 times, resulting in a remainder of 396.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 490 from 886, we get 396.
Append the next digit (4) from the dividend to 396 and continue with: 3964 / 490

Moving on to step 4:
When dividing 3964 by 490, we get 8 with a remainder of 44.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 3920 from 3964, we get 44.
Grab the next digit (7) from the dividend, add it to 44, then carry on: 447 / 490

On to step 5:
490 can be fit into 447 0 times, resulting in a remainder of 447.
Use 0 as the next digit of our solution. 
Result so far: 180.0
Deduct 0 from 447 and we're left with 447.
Take the next digit (7) from the dividend and append it to 447, then repeat: 4477 / 490

Moving on to step 6:
490 goes into 4477 9 times with a remainder of 67.
Use 9 as the next digit of our solution. 
Result so far: 1809.0
Subtract 4410 from 4477 to get 67.
Take the next digit (8) from the dividend and append it to 67, then repeat: 678 / 490

Step 7:
490 can be fit into 678 1 times, resulting in a remainder of 188.
The next digit of our result is 1. 
Result so far: 18091.0
If we take 490 away from 678, we end up with 188.
Include the next digit (9) from the dividend after 188, then repeat: 1889 / 490

Going ahead to step 8:
If we divide 1889 by 490, we get 3 and a remainder of 419.
The next digit of our result is 3. 
Result so far: 180913.0
If we subtract 1470 from 1889, we get 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Going ahead to step 9:
490 can be fit into 4190 8 times, resulting in a remainder of 270.
Record the quotient 8 as the next digit in the result. 
Result so far: 180913.8
Subtract 3920 from 4190 to get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 10:
When dividing 2700 by 490, we get 5 with a remainder of 250.
Use 5 as the next digit of our solution. 
Result so far: 180913.85
Deduct 2450 from 2700 and we're left with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Going ahead to step 11:
490 can be fit into 2500 5 times, resulting in a remainder of 50.
The next digit of our result is 5. 
Result so far: 180913.855
Deduct 2450 from 2500 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 180913.855 with a remaining 0.005.
