We look at the division of 3957177 by 499 
The aim is to understand the frequency of 499 in 3957177.

Going ahead to step 1:
When dividing 3 by 499, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 499

Step 2:
499 goes into 39 0 times with a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Grab the next digit (5) from the dividend, add it to 39, then carry on: 395 / 499

Moving on to step 3:
The number 499 fits into 395 0 times, leaving a remainder of 395.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 395, we end up with 395.
Bring next digit (7) of the dividend behind the 395 and repeat the process: 3957 / 499

On to step 4:
If we divide 3957 by 499, we get 7 and a remainder of 464.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 3493 from 3957 leaves us with 464.
Fetch the next digit (1) from the dividend, attach it to 464 and continue: 4641 / 499

Step 5:
When dividing 4641 by 499, we get 9 with a remainder of 150.
Write down 9 as next digit of the result. 
Result so far: 79.0
If we subtract 4491 from 4641, we get 150.
Fetch the next digit (7) from the dividend, attach it to 150 and continue: 1507 / 499

On to step 6:
If we divide 1507 by 499, we get 3 and a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 793.0
Subtracting 1497 from 1507 leaves us with 10.
Bring next digit (7) of the dividend behind the 10 and repeat the process: 107 / 499

Step 7:
499 can be fit into 107 0 times, resulting in a remainder of 107.
Use 0 as the next digit of our solution. 
Result so far: 7930.0
If we subtract 0 from 107, we get 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 8:
If we divide 1070 by 499, we get 2 and a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 7930.2
Subtracting 998 from 1070 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 9:
499 goes into 720 1 times with a remainder of 221.
Record the quotient 1 as the next digit in the result. 
Result so far: 7930.21
Deduct 499 from 720 and we're left with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Moving on to step 10:
2210 divided by 499 is 4 with a remainder of 214.
Use 4 as the next digit of our solution. 
Result so far: 7930.214
Subtract 1996 from 2210 to get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

On to step 11:
The number 499 fits into 2140 4 times, leaving a remainder of 144.
The next digit of our result is 4. 
Result so far: 7930.2144
If we subtract 1996 from 2140, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

The final outcome is 7930.2144, with a leftover of 0.00144.
