We look at the division of 36851540 by 497 
The aim is to understand the frequency of 497 in 36851540.

Moving on to step 1:
If we divide 3 by 497, we get 0 and 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 (6) from the dividend, add it to 3, then carry on: 36 / 497

Advancing to step 2:
The number 497 fits into 36 0 times, leaving a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 36 and we're left with 36.
Grab the next digit (8) from the dividend, add it to 36, then carry on: 368 / 497

Step 3:
If we divide 368 by 497, we get 0 and a remainder of 368.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 368 leaves us with 368.
Include the next digit (5) from the dividend after 368, then repeat: 3685 / 497

On to step 4:
3685 divided by 497 is 7 with a remainder of 206.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Deduct 3479 from 3685 and we're left with 206.
Bring next digit (1) of the dividend behind the 206 and repeat the process: 2061 / 497

Moving on to step 5:
497 can be fit into 2061 4 times, resulting in a remainder of 73.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
Subtract 1988 from 2061 to get 73.
Include the next digit (5) from the dividend after 73, then repeat: 735 / 497

Advancing to step 6:
735 divided by 497 is 1 with a remainder of 238.
Record the quotient 1 as the next digit in the result. 
Result so far: 741.0
The remainder is 238 after subtracting 497 from 735.
Bring next digit (4) of the dividend behind the 238 and repeat the process: 2384 / 497

Moving on to step 7:
When dividing 2384 by 497, we get 4 with a remainder of 396.
The number 4 becomes the next digit in our result. 
Result so far: 7414.0
Subtract 1988 from 2384 to get 396.
Fetch the next digit (0) from the dividend, attach it to 396 and continue: 3960 / 497

Let's proceed to step 8:
497 can be fit into 3960 7 times, resulting in a remainder of 481.
Put 7 as the next digit of the answer. 
Result so far: 74147.0
Subtracting 3479 from 3960 leaves us with 481.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4810, and continue the process.

Let's proceed to step 9:
497 can be fit into 4810 9 times, resulting in a remainder of 337.
The next digit of our result is 9. 
Result so far: 74147.9
If we subtract 4473 from 4810, we get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Advancing to step 10:
497 can be fit into 3370 6 times, resulting in a remainder of 388.
Use 6 as the next digit of our solution. 
Result so far: 74147.96
Subtracting 2982 from 3370 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 11:
3880 divided by 497 is 7 with a remainder of 401.
The next digit of our result is 7. 
Result so far: 74147.967
Subtract 3479 from 3880 to get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Moving on to step 12:
497 goes into 4010 8 times with a remainder of 34.
The next digit of our result is 8. 
Result so far: 74147.9678
Deduct 3976 from 4010 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 13:
340 divided by 497 is 0 with a remainder of 340.
Use 0 as the next digit of our solution. 
Result so far: 74147.9678
If we take 0 away from 340, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 14:
3400 divided by 497 is 6 with a remainder of 418.
Write down 6 as next digit of the result. 
Result so far: 74147.967806
Deduct 2982 from 3400 and we're left with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

Moving on to step 15:
If we divide 4180 by 497, we get 8 and a remainder of 204.
Write down 8 as next digit of the result. 
Result so far: 74147.9678068
If we subtract 3976 from 4180, we get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

On to step 16:
When dividing 2040 by 497, we get 4 with a remainder of 52.
Write down 4 as next digit of the result. 
Result so far: 74147.96780684
Deduct 1988 from 2040 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Our division results in 74147.96780684 with a remaining 5.2e-08.
