We look at the division of 27789188 by 545 
The aim is to understand the frequency of 545 in 27789188.

Let's proceed to step 1:
545 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 545

On to step 2:
545 goes into 27 0 times with a remainder of 27.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 545

Moving on to step 3:
545 goes into 277 0 times with a remainder of 277.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 277 leaves us with 277.
Append the next digit (8) from the dividend to 277 and continue with: 2778 / 545

Going ahead to step 4:
The number 545 fits into 2778 5 times, leaving a remainder of 53.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 2725 from 2778 and we're left with 53.
Take the next digit (9) from the dividend and append it to 53, then repeat: 539 / 545

Going ahead to step 5:
545 can be fit into 539 0 times, resulting in a remainder of 539.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
If we subtract 0 from 539, we get 539.
Grab the next digit (1) from the dividend, add it to 539, then carry on: 5391 / 545

Going ahead to step 6:
When dividing 5391 by 545, we get 9 with a remainder of 486.
Write down 9 as next digit of the result. 
Result so far: 509.0
Subtract 4905 from 5391 to get 486.
Fetch the next digit (8) from the dividend, attach it to 486 and continue: 4868 / 545

On to step 7:
4868 divided by 545 is 8 with a remainder of 508.
Use 8 as the next digit of our solution. 
Result so far: 5098.0
The remainder is 508 after subtracting 4360 from 4868.
Grab the next digit (8) from the dividend, add it to 508, then carry on: 5088 / 545

Step 8:
5088 divided by 545 is 9 with a remainder of 183.
Record the quotient 9 as the next digit in the result. 
Result so far: 50989.0
Subtract 4905 from 5088 to get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Moving on to step 9:
1830 divided by 545 is 3 with a remainder of 195.
The next digit of our result is 3. 
Result so far: 50989.3
Subtracting 1635 from 1830 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Advancing to step 10:
1950 divided by 545 is 3 with a remainder of 315.
Record the quotient 3 as the next digit in the result. 
Result so far: 50989.33
Subtracting 1635 from 1950 leaves us with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

After the division, we end up with 50989.33 and a remainder of 0.315.
