We're dividing 19586761 by 499 
The aim is to understand the frequency of 499 in 19586761.

On to step 1:
If we divide 1 by 499, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 499

Moving on to step 2:
The number 499 fits into 19 0 times, leaving a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 499

Step 3:
499 goes into 195 0 times with a remainder of 195.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 195 to get 195.
Include the next digit (8) from the dividend after 195, then repeat: 1958 / 499

Going ahead to step 4:
When dividing 1958 by 499, we get 3 with a remainder of 461.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 1497 from 1958 and we're left with 461.
Take the next digit (6) from the dividend and append it to 461, then repeat: 4616 / 499

Step 5:
The number 499 fits into 4616 9 times, leaving a remainder of 125.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
Subtracting 4491 from 4616 leaves us with 125.
Bring next digit (7) of the dividend behind the 125 and repeat the process: 1257 / 499

On to step 6:
499 can be fit into 1257 2 times, resulting in a remainder of 259.
Record the quotient 2 as the next digit in the result. 
Result so far: 392.0
Subtract 998 from 1257 to get 259.
Fetch the next digit (6) from the dividend, attach it to 259 and continue: 2596 / 499

Moving on to step 7:
499 goes into 2596 5 times with a remainder of 101.
The number 5 becomes the next digit in our result. 
Result so far: 3925.0
Deduct 2495 from 2596 and we're left with 101.
Include the next digit (1) from the dividend after 101, then repeat: 1011 / 499

Advancing to step 8:
499 goes into 1011 2 times with a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 39252.0
Deduct 998 from 1011 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
499 can be fit into 130 0 times, resulting in a remainder of 130.
The next digit of our result is 0. 
Result so far: 39252.0
Deduct 0 from 130 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
499 can be fit into 1300 2 times, resulting in a remainder of 302.
Use 2 as the next digit of our solution. 
Result so far: 39252.02
If we take 998 away from 1300, we end up with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Going ahead to step 11:
3020 divided by 499 is 6 with a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 39252.026
Subtract 2994 from 3020 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
499 can be fit into 260 0 times, resulting in a remainder of 260.
Write down 0 as next digit of the result. 
Result so far: 39252.026
Subtract 0 from 260 to get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 13:
When dividing 2600 by 499, we get 5 with a remainder of 105.
The next digit of our result is 5. 
Result so far: 39252.02605
If we subtract 2495 from 2600, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 14:
The number 499 fits into 1050 2 times, leaving a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 39252.026052
Deduct 998 from 1050 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.

Advancing to step 15:
499 goes into 520 1 times with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 39252.0260521
If we subtract 499 from 520, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 16:
499 goes into 210 0 times with a remainder of 210.
Record the quotient 0 as the next digit in the result. 
Result so far: 39252.0260521
Subtract 0 from 210 to get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

The final outcome is 39252.0260521, with a leftover of 2.1e-07.
