80953580 divided by 499 
The aim is to understand the frequency of 499 in 80953580.

Going ahead to step 1:
499 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 499

On to step 2:
The number 499 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Take the next digit (9) from the dividend and append it to 80, then repeat: 809 / 499

Moving on to step 3:
809 divided by 499 is 1 with a remainder of 310.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 499 from 809, we get 310.
Bring next digit (5) of the dividend behind the 310 and repeat the process: 3105 / 499

Moving on to step 4:
When dividing 3105 by 499, we get 6 with a remainder of 111.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Deduct 2994 from 3105 and we're left with 111.
Bring next digit (3) of the dividend behind the 111 and repeat the process: 1113 / 499

Going ahead to step 5:
499 goes into 1113 2 times with a remainder of 115.
The next digit of our result is 2. 
Result so far: 162.0
Deduct 998 from 1113 and we're left with 115.
Include the next digit (5) from the dividend after 115, then repeat: 1155 / 499

Step 6:
The number 499 fits into 1155 2 times, leaving a remainder of 157.
The number 2 becomes the next digit in our result. 
Result so far: 1622.0
If we take 998 away from 1155, we end up with 157.
Take the next digit (8) from the dividend and append it to 157, then repeat: 1578 / 499

Moving on to step 7:
When dividing 1578 by 499, we get 3 with a remainder of 81.
The next digit of our result is 3. 
Result so far: 16223.0
If we take 1497 away from 1578, we end up with 81.
Take the next digit (0) from the dividend and append it to 81, then repeat: 810 / 499

Going ahead to step 8:
If we divide 810 by 499, we get 1 and a remainder of 311.
Use 1 as the next digit of our solution. 
Result so far: 162231.0
Subtract 499 from 810 to get 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Let's proceed to step 9:
499 goes into 3110 6 times with a remainder of 116.
The number 6 becomes the next digit in our result. 
Result so far: 162231.6
Deduct 2994 from 3110 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

On to step 10:
If we divide 1160 by 499, we get 2 and a remainder of 162.
Put 2 as the next digit of the answer. 
Result so far: 162231.62
Subtracting 998 from 1160 leaves us with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Advancing to step 11:
When dividing 1620 by 499, we get 3 with a remainder of 123.
The number 3 becomes the next digit in our result. 
Result so far: 162231.623
If we subtract 1497 from 1620, we get 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Let's proceed to step 12:
If we divide 1230 by 499, we get 2 and a remainder of 232.
Use 2 as the next digit of our solution. 
Result so far: 162231.6232
Subtracting 998 from 1230 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 13:
499 goes into 2320 4 times with a remainder of 324.
Record the quotient 4 as the next digit in the result. 
Result so far: 162231.62324
The remainder is 324 after subtracting 1996 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

Going ahead to step 14:
The number 499 fits into 3240 6 times, leaving a remainder of 246.
Put 6 as the next digit of the answer. 
Result so far: 162231.623246
If we subtract 2994 from 3240, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Advancing to step 15:
2460 divided by 499 is 4 with a remainder of 464.
The next digit of our result is 4. 
Result so far: 162231.6232464
Deduct 1996 from 2460 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Step 16:
499 goes into 4640 9 times with a remainder of 149.
Use 9 as the next digit of our solution. 
Result so far: 162231.62324649
The remainder is 149 after subtracting 4491 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1490, and continue the process.

The final outcome is 162231.62324649, with a leftover of 1.49e-07.
