We look at the division of 21892005 by 545 
The aim is to understand the frequency of 545 in 21892005.

Moving on to step 1:
When dividing 2 by 545, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 545

Let's proceed to step 2:
21 divided by 545 is 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (8) from the dividend to 21 and continue with: 218 / 545

Let's proceed to step 3:
When dividing 218 by 545, we get 0 with a remainder of 218.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 218 leaves us with 218.
Append the next digit (9) from the dividend to 218 and continue with: 2189 / 545

Advancing to step 4:
545 goes into 2189 4 times with a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 2180 away from 2189, we end up with 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 545

Moving on to step 5:
545 can be fit into 92 0 times, resulting in a remainder of 92.
Write down 0 as next digit of the result. 
Result so far: 40.0
The remainder is 92 after subtracting 0 from 92.
Append the next digit (0) from the dividend to 92 and continue with: 920 / 545

Advancing to step 6:
920 divided by 545 is 1 with a remainder of 375.
Record the quotient 1 as the next digit in the result. 
Result so far: 401.0
If we take 545 away from 920, we end up with 375.
Bring next digit (0) of the dividend behind the 375 and repeat the process: 3750 / 545

Moving on to step 7:
When dividing 3750 by 545, we get 6 with a remainder of 480.
Write down 6 as next digit of the result. 
Result so far: 4016.0
If we subtract 3270 from 3750, we get 480.
Append the next digit (5) from the dividend to 480 and continue with: 4805 / 545

Step 8:
If we divide 4805 by 545, we get 8 and a remainder of 445.
The next digit of our result is 8. 
Result so far: 40168.0
If we take 4360 away from 4805, we end up with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Let's proceed to step 9:
545 can be fit into 4450 8 times, resulting in a remainder of 90.
Write down 8 as next digit of the result. 
Result so far: 40168.8
The remainder is 90 after subtracting 4360 from 4450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 10:
The number 545 fits into 900 1 times, leaving a remainder of 355.
The next digit of our result is 1. 
Result so far: 40168.81
Subtract 545 from 900 to get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Moving on to step 11:
545 can be fit into 3550 6 times, resulting in a remainder of 280.
The next digit of our result is 6. 
Result so far: 40168.816
Deduct 3270 from 3550 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Advancing to step 12:
545 can be fit into 2800 5 times, resulting in a remainder of 75.
The next digit of our result is 5. 
Result so far: 40168.8165
The remainder is 75 after subtracting 2725 from 2800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 13:
When dividing 750 by 545, we get 1 with a remainder of 205.
The number 1 becomes the next digit in our result. 
Result so far: 40168.81651
The remainder is 205 after subtracting 545 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Advancing to step 14:
545 can be fit into 2050 3 times, resulting in a remainder of 415.
The number 3 becomes the next digit in our result. 
Result so far: 40168.816513
If we take 1635 away from 2050, we end up with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Going ahead to step 15:
If we divide 4150 by 545, we get 7 and a remainder of 335.
Use 7 as the next digit of our solution. 
Result so far: 40168.8165137
Subtract 3815 from 4150 to get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Advancing to step 16:
The number 545 fits into 3350 6 times, leaving a remainder of 80.
The next digit of our result is 6. 
Result so far: 40168.81651376
Subtracting 3270 from 3350 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final outcome is 40168.81651376, with a leftover of 8e-08.
