39970479 divided by 495 
The aim is to understand the frequency of 495 in 39970479.

Advancing to step 1:
When dividing 3 by 495, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 495

Step 2:
The number 495 fits into 39 0 times, leaving a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Include the next digit (9) from the dividend after 39, then repeat: 399 / 495

On to step 3:
The number 495 fits into 399 0 times, leaving a remainder of 399.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 399 to get 399.
Include the next digit (7) from the dividend after 399, then repeat: 3997 / 495

Going ahead to step 4:
If we divide 3997 by 495, we get 8 and a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 3960 from 3997 leaves us with 37.
Include the next digit (0) from the dividend after 37, then repeat: 370 / 495

On to step 5:
370 divided by 495 is 0 with a remainder of 370.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Subtracting 0 from 370 leaves us with 370.
Fetch the next digit (4) from the dividend, attach it to 370 and continue: 3704 / 495

Going ahead to step 6:
3704 divided by 495 is 7 with a remainder of 239.
Write down 7 as next digit of the result. 
Result so far: 807.0
Subtract 3465 from 3704 to get 239.
Take the next digit (7) from the dividend and append it to 239, then repeat: 2397 / 495

Advancing to step 7:
495 goes into 2397 4 times with a remainder of 417.
Write down 4 as next digit of the result. 
Result so far: 8074.0
The remainder is 417 after subtracting 1980 from 2397.
Bring next digit (9) of the dividend behind the 417 and repeat the process: 4179 / 495

Step 8:
495 goes into 4179 8 times with a remainder of 219.
Put 8 as the next digit of the answer. 
Result so far: 80748.0
The remainder is 219 after subtracting 3960 from 4179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Step 9:
495 can be fit into 2190 4 times, resulting in a remainder of 210.
Put 4 as the next digit of the answer. 
Result so far: 80748.4
Subtracting 1980 from 2190 leaves us with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Let's proceed to step 10:
2100 divided by 495 is 4 with a remainder of 120.
Put 4 as the next digit of the answer. 
Result so far: 80748.44
Deduct 1980 from 2100 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

In conclusion, the division gives 80748.44 with a balance of 0.12.
