89670551 divided by 538 
The aim is to understand the frequency of 538 in 89670551.

Moving on to step 1:
538 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 538

On to step 2:
538 can be fit into 89 0 times, resulting in a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 89 after subtracting 0 from 89.
Take the next digit (6) from the dividend and append it to 89, then repeat: 896 / 538

Moving on to step 3:
896 divided by 538 is 1 with a remainder of 358.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 538 from 896 leaves us with 358.
Append the next digit (7) from the dividend to 358 and continue with: 3587 / 538

Let's proceed to step 4:
3587 divided by 538 is 6 with a remainder of 359.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
If we take 3228 away from 3587, we end up with 359.
Include the next digit (0) from the dividend after 359, then repeat: 3590 / 538

On to step 5:
When dividing 3590 by 538, we get 6 with a remainder of 362.
Write down 6 as next digit of the result. 
Result so far: 166.0
The remainder is 362 after subtracting 3228 from 3590.
Take the next digit (5) from the dividend and append it to 362, then repeat: 3625 / 538

Moving on to step 6:
The number 538 fits into 3625 6 times, leaving a remainder of 397.
The next digit of our result is 6. 
Result so far: 1666.0
If we subtract 3228 from 3625, we get 397.
Take the next digit (5) from the dividend and append it to 397, then repeat: 3975 / 538

Step 7:
3975 divided by 538 is 7 with a remainder of 209.
Record the quotient 7 as the next digit in the result. 
Result so far: 16667.0
If we take 3766 away from 3975, we end up with 209.
Grab the next digit (1) from the dividend, add it to 209, then carry on: 2091 / 538

Moving on to step 8:
When dividing 2091 by 538, we get 3 with a remainder of 477.
Put 3 as the next digit of the answer. 
Result so far: 166673.0
If we subtract 1614 from 2091, we get 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Step 9:
If we divide 4770 by 538, we get 8 and a remainder of 466.
Write down 8 as next digit of the result. 
Result so far: 166673.8
If we take 4304 away from 4770, we end up with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Moving on to step 10:
When dividing 4660 by 538, we get 8 with a remainder of 356.
Record the quotient 8 as the next digit in the result. 
Result so far: 166673.88
Deduct 4304 from 4660 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

After the division, we end up with 166673.88 and a remainder of 0.356.
