7853570 divided by 499 
The aim is to understand the frequency of 499 in 7853570.

Moving on to step 1:
If we divide 7 by 499, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 499

Step 2:
When dividing 78 by 499, we get 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Bring next digit (5) of the dividend behind the 78 and repeat the process: 785 / 499

Moving on to step 3:
785 divided by 499 is 1 with a remainder of 286.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 286 after subtracting 499 from 785.
Fetch the next digit (3) from the dividend, attach it to 286 and continue: 2863 / 499

Step 4:
2863 divided by 499 is 5 with a remainder of 368.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we subtract 2495 from 2863, we get 368.
Append the next digit (5) from the dividend to 368 and continue with: 3685 / 499

Going ahead to step 5:
If we divide 3685 by 499, we get 7 and a remainder of 192.
The next digit of our result is 7. 
Result so far: 157.0
Subtract 3493 from 3685 to get 192.
Take the next digit (7) from the dividend and append it to 192, then repeat: 1927 / 499

Step 6:
499 goes into 1927 3 times with a remainder of 430.
Put 3 as the next digit of the answer. 
Result so far: 1573.0
If we subtract 1497 from 1927, we get 430.
Take the next digit (0) from the dividend and append it to 430, then repeat: 4300 / 499

On to step 7:
The number 499 fits into 4300 8 times, leaving a remainder of 308.
The next digit of our result is 8. 
Result so far: 15738.0
Deduct 3992 from 4300 and we're left with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 8:
When dividing 3080 by 499, we get 6 with a remainder of 86.
Record the quotient 6 as the next digit in the result. 
Result so far: 15738.6
Deduct 2994 from 3080 and we're left with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Moving on to step 9:
The number 499 fits into 860 1 times, leaving a remainder of 361.
Write down 1 as next digit of the result. 
Result so far: 15738.61
Subtract 499 from 860 to get 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Advancing to step 10:
If we divide 3610 by 499, we get 7 and a remainder of 117.
Use 7 as the next digit of our solution. 
Result so far: 15738.617
Subtract 3493 from 3610 to get 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Moving on to step 11:
If we divide 1170 by 499, we get 2 and a remainder of 172.
Put 2 as the next digit of the answer. 
Result so far: 15738.6172
Subtracting 998 from 1170 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 12:
499 can be fit into 1720 3 times, resulting in a remainder of 223.
Use 3 as the next digit of our solution. 
Result so far: 15738.61723
Subtract 1497 from 1720 to get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Moving on to step 13:
If we divide 2230 by 499, we get 4 and a remainder of 234.
Put 4 as the next digit of the answer. 
Result so far: 15738.617234
If we subtract 1996 from 2230, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Going ahead to step 14:
The number 499 fits into 2340 4 times, leaving a remainder of 344.
Write down 4 as next digit of the result. 
Result so far: 15738.6172344
If we take 1996 away from 2340, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

After the division, we end up with 15738.6172344 and a remainder of 3.44e-06.
