We divide 486536 by 497
The aim is to understand the frequency of 497 in 486536.

Going ahead to step 1:
When dividing 4 by 497, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 497

On to step 2:
When dividing 48 by 497, we get 0 with a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Grab the next digit (6) from the dividend, add it to 48, then carry on: 486 / 497

On to step 3:
If we divide 486 by 497, we get 0 and a remainder of 486.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 486 and we're left with 486.
Take the next digit (5) from the dividend and append it to 486, then repeat: 4865 / 497

Step 4:
4865 divided by 497 is 9 with a remainder of 392.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 4473 from 4865, we get 392.
Fetch the next digit (3) from the dividend, attach it to 392 and continue: 3923 / 497

On to step 5:
497 can be fit into 3923 7 times, resulting in a remainder of 444.
The number 7 becomes the next digit in our result. 
Result so far: 97.0
Subtracting 3479 from 3923 leaves us with 444.
Grab the next digit (6) from the dividend, add it to 444, then carry on: 4446 / 497

Step 6:
If we divide 4446 by 497, we get 8 and a remainder of 470.
Write down 8 as next digit of the result. 
Result so far: 978.0
Deduct 3976 from 4446 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Advancing to step 7:
497 can be fit into 4700 9 times, resulting in a remainder of 227.
Record the quotient 9 as the next digit in the result. 
Result so far: 978.9
If we subtract 4473 from 4700, we get 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

On to step 8:
497 goes into 2270 4 times with a remainder of 282.
Put 4 as the next digit of the answer. 
Result so far: 978.94
Subtracting 1988 from 2270 leaves us with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 9:
497 goes into 2820 5 times with a remainder of 335.
The next digit of our result is 5. 
Result so far: 978.945
Subtracting 2485 from 2820 leaves us with 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Going ahead to step 10:
497 goes into 3350 6 times with a remainder of 368.
Put 6 as the next digit of the answer. 
Result so far: 978.9456
If we take 2982 away from 3350, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

On to step 11:
When dividing 3680 by 497, we get 7 with a remainder of 201.
Use 7 as the next digit of our solution. 
Result so far: 978.94567
Deduct 3479 from 3680 and we're left with 201.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2010, and continue the process.

Step 12:
497 goes into 2010 4 times with a remainder of 22.
Record the quotient 4 as the next digit in the result. 
Result so far: 978.945674
Deduct 1988 from 2010 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
If we divide 220 by 497, we get 0 and a remainder of 220.
The number 0 becomes the next digit in our result. 
Result so far: 978.945674
Subtracting 0 from 220 leaves us with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 14:
If we divide 2200 by 497, we get 4 and a remainder of 212.
Use 4 as the next digit of our solution. 
Result so far: 978.94567404
Subtracting 1988 from 2200 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

The final result is 978.94567404 with a remainder of 2.12e-07.
