80218259 ÷ 531 
The aim is to understand the frequency of 531 in 80218259.

Let's proceed to step 1:
531 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 531

On to step 2:
If we divide 80 by 531, we get 0 and a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Append the next digit (2) from the dividend to 80 and continue with: 802 / 531

Let's proceed to step 3:
The number 531 fits into 802 1 times, leaving a remainder of 271.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 531 from 802 to get 271.
Bring next digit (1) of the dividend behind the 271 and repeat the process: 2711 / 531

On to step 4:
If we divide 2711 by 531, we get 5 and a remainder of 56.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 56 after subtracting 2655 from 2711.
Fetch the next digit (8) from the dividend, attach it to 56 and continue: 568 / 531

Going ahead to step 5:
531 goes into 568 1 times with a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 151.0
The remainder is 37 after subtracting 531 from 568.
Include the next digit (2) from the dividend after 37, then repeat: 372 / 531

Advancing to step 6:
When dividing 372 by 531, we get 0 with a remainder of 372.
Use 0 as the next digit of our solution. 
Result so far: 1510.0
The remainder is 372 after subtracting 0 from 372.
Append the next digit (5) from the dividend to 372 and continue with: 3725 / 531

Step 7:
3725 divided by 531 is 7 with a remainder of 8.
The next digit of our result is 7. 
Result so far: 15107.0
If we take 3717 away from 3725, we end up with 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 531

Going ahead to step 8:
When dividing 89 by 531, we get 0 with a remainder of 89.
Write down 0 as next digit of the result. 
Result so far: 151070.0
Deduct 0 from 89 and we're left with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Advancing to step 9:
531 can be fit into 890 1 times, resulting in a remainder of 359.
Record the quotient 1 as the next digit in the result. 
Result so far: 151070.1
Deduct 531 from 890 and we're left with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Moving on to step 10:
If we divide 3590 by 531, we get 6 and a remainder of 404.
Use 6 as the next digit of our solution. 
Result so far: 151070.16
Subtract 3186 from 3590 to get 404.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Step 11:
531 goes into 4040 7 times with a remainder of 323.
Write down 7 as next digit of the result. 
Result so far: 151070.167
If we take 3717 away from 4040, we end up with 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Advancing to step 12:
When dividing 3230 by 531, we get 6 with a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 151070.1676
Subtract 3186 from 3230 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 13:
440 divided by 531 is 0 with a remainder of 440.
The number 0 becomes the next digit in our result. 
Result so far: 151070.1676
If we take 0 away from 440, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

On to step 14:
When dividing 4400 by 531, we get 8 with a remainder of 152.
Use 8 as the next digit of our solution. 
Result so far: 151070.167608
Subtract 4248 from 4400 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 15:
If we divide 1520 by 531, we get 2 and a remainder of 458.
Use 2 as the next digit of our solution. 
Result so far: 151070.1676082
Subtract 1062 from 1520 to get 458.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Advancing to step 16:
531 goes into 4580 8 times with a remainder of 332.
Write down 8 as next digit of the result. 
Result so far: 151070.16760828
The remainder is 332 after subtracting 4248 from 4580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

The quotient of the division is 151070.16760828, and the remainder is 3.32e-07.
