Let's divide 91543064 by 499
The aim is to understand the frequency of 499 in 91543064.

Step 1:
If we divide 9 by 499, we get 0 and a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 499

Step 2:
91 divided by 499 is 0 with a remainder of 91.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 91, we get 91.
Bring next digit (5) of the dividend behind the 91 and repeat the process: 915 / 499

Going ahead to step 3:
The number 499 fits into 915 1 times, leaving a remainder of 416.
The next digit of our result is 1. 
Result so far: 1.0
If we take 499 away from 915, we end up with 416.
Grab the next digit (4) from the dividend, add it to 416, then carry on: 4164 / 499

Let's proceed to step 4:
499 goes into 4164 8 times with a remainder of 172.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Deduct 3992 from 4164 and we're left with 172.
Include the next digit (3) from the dividend after 172, then repeat: 1723 / 499

Going ahead to step 5:
1723 divided by 499 is 3 with a remainder of 226.
Put 3 as the next digit of the answer. 
Result so far: 183.0
Subtract 1497 from 1723 to get 226.
Include the next digit (0) from the dividend after 226, then repeat: 2260 / 499

Advancing to step 6:
2260 divided by 499 is 4 with a remainder of 264.
Write down 4 as next digit of the result. 
Result so far: 1834.0
Deduct 1996 from 2260 and we're left with 264.
Fetch the next digit (6) from the dividend, attach it to 264 and continue: 2646 / 499

Going ahead to step 7:
If we divide 2646 by 499, we get 5 and a remainder of 151.
Use 5 as the next digit of our solution. 
Result so far: 18345.0
If we subtract 2495 from 2646, we get 151.
Append the next digit (4) from the dividend to 151 and continue with: 1514 / 499

On to step 8:
499 can be fit into 1514 3 times, resulting in a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 183453.0
Subtract 1497 from 1514 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 9:
The number 499 fits into 170 0 times, leaving a remainder of 170.
Put 0 as the next digit of the answer. 
Result so far: 183453.0
If we take 0 away from 170, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 10:
499 can be fit into 1700 3 times, resulting in a remainder of 203.
The number 3 becomes the next digit in our result. 
Result so far: 183453.03
The remainder is 203 after subtracting 1497 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Going ahead to step 11:
2030 divided by 499 is 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 183453.034
The remainder is 34 after subtracting 1996 from 2030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
340 divided by 499 is 0 with a remainder of 340.
Record the quotient 0 as the next digit in the result. 
Result so far: 183453.034
Deduct 0 from 340 and we're left 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.

Going ahead to step 13:
When dividing 3400 by 499, we get 6 with a remainder of 406.
Record the quotient 6 as the next digit in the result. 
Result so far: 183453.03406
Subtracting 2994 from 3400 leaves us with 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Step 14:
499 goes into 4060 8 times with a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 183453.034068
If we take 3992 away from 4060, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 15:
499 goes into 680 1 times with a remainder of 181.
Use 1 as the next digit of our solution. 
Result so far: 183453.0340681
The remainder is 181 after subtracting 499 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Step 16:
1810 divided by 499 is 3 with a remainder of 313.
Record the quotient 3 as the next digit in the result. 
Result so far: 183453.03406813
If we take 1497 away from 1810, we end up with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

The final outcome is 183453.03406813, with a leftover of 3.13e-07.
