20748887 divided by 495 
The aim is to understand the frequency of 495 in 20748887.

Advancing to step 1:
The number 495 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 495

On to step 2:
495 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 495

Going ahead to step 3:
If we divide 207 by 495, we get 0 and a remainder of 207.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 207 leaves us with 207.
Bring next digit (4) of the dividend behind the 207 and repeat the process: 2074 / 495

Advancing to step 4:
If we divide 2074 by 495, we get 4 and a remainder of 94.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 1980 from 2074 and we're left with 94.
Append the next digit (8) from the dividend to 94 and continue with: 948 / 495

Moving on to step 5:
495 can be fit into 948 1 times, resulting in a remainder of 453.
Use 1 as the next digit of our solution. 
Result so far: 41.0
The remainder is 453 after subtracting 495 from 948.
Take the next digit (8) from the dividend and append it to 453, then repeat: 4538 / 495

On to step 6:
495 goes into 4538 9 times with a remainder of 83.
The number 9 becomes the next digit in our result. 
Result so far: 419.0
Subtracting 4455 from 4538 leaves us with 83.
Include the next digit (8) from the dividend after 83, then repeat: 838 / 495

On to step 7:
If we divide 838 by 495, we get 1 and a remainder of 343.
The next digit of our result is 1. 
Result so far: 4191.0
If we take 495 away from 838, we end up with 343.
Take the next digit (7) from the dividend and append it to 343, then repeat: 3437 / 495

Advancing to step 8:
The number 495 fits into 3437 6 times, leaving a remainder of 467.
Put 6 as the next digit of the answer. 
Result so far: 41916.0
If we subtract 2970 from 3437, we get 467.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4670, and continue the process.

Advancing to step 9:
The number 495 fits into 4670 9 times, leaving a remainder of 215.
Use 9 as the next digit of our solution. 
Result so far: 41916.9
Deduct 4455 from 4670 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

On to step 10:
495 goes into 2150 4 times with a remainder of 170.
Record the quotient 4 as the next digit in the result. 
Result so far: 41916.94
Subtract 1980 from 2150 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 11:
495 goes into 1700 3 times with a remainder of 215.
Put 3 as the next digit of the answer. 
Result so far: 41916.943
The remainder is 215 after subtracting 1485 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 12:
When dividing 2150 by 495, we get 4 with a remainder of 170.
Use 4 as the next digit of our solution. 
Result so far: 41916.9434
If we take 1980 away from 2150, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 13:
The number 495 fits into 1700 3 times, leaving a remainder of 215.
The next digit of our result is 3. 
Result so far: 41916.94343
Deduct 1485 from 1700 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 14:
The number 495 fits into 2150 4 times, leaving a remainder of 170.
Put 4 as the next digit of the answer. 
Result so far: 41916.943434
The remainder is 170 after subtracting 1980 from 2150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Let's proceed to step 15:
1700 divided by 495 is 3 with a remainder of 215.
Put 3 as the next digit of the answer. 
Result so far: 41916.9434343
The remainder is 215 after subtracting 1485 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 16:
The number 495 fits into 2150 4 times, leaving a remainder of 170.
Put 4 as the next digit of the answer. 
Result so far: 41916.94343434
Subtract 1980 from 2150 to get 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.
