99452515 ÷ 531 
The aim is to understand the frequency of 531 in 99452515.

Step 1:
9 divided by 531 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 531

Going ahead to step 2:
If we divide 99 by 531, we get 0 and a remainder of 99.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 99, we end up with 99.
Bring next digit (4) of the dividend behind the 99 and repeat the process: 994 / 531

Going ahead to step 3:
531 can be fit into 994 1 times, resulting in a remainder of 463.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 531 from 994, we get 463.
Grab the next digit (5) from the dividend, add it to 463, then carry on: 4635 / 531

Going ahead to step 4:
When dividing 4635 by 531, we get 8 with a remainder of 387.
Use 8 as the next digit of our solution. 
Result so far: 18.0
If we subtract 4248 from 4635, we get 387.
Take the next digit (2) from the dividend and append it to 387, then repeat: 3872 / 531

Advancing to step 5:
If we divide 3872 by 531, we get 7 and a remainder of 155.
Put 7 as the next digit of the answer. 
Result so far: 187.0
If we subtract 3717 from 3872, we get 155.
Take the next digit (5) from the dividend and append it to 155, then repeat: 1555 / 531

Step 6:
1555 divided by 531 is 2 with a remainder of 493.
Put 2 as the next digit of the answer. 
Result so far: 1872.0
Deduct 1062 from 1555 and we're left with 493.
Append the next digit (1) from the dividend to 493 and continue with: 4931 / 531

Going ahead to step 7:
If we divide 4931 by 531, we get 9 and a remainder of 152.
Put 9 as the next digit of the answer. 
Result so far: 18729.0
Deduct 4779 from 4931 and we're left with 152.
Include the next digit (5) from the dividend after 152, then repeat: 1525 / 531

Going ahead to step 8:
531 goes into 1525 2 times with a remainder of 463.
Use 2 as the next digit of our solution. 
Result so far: 187292.0
Subtracting 1062 from 1525 leaves us with 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

On to step 9:
If we divide 4630 by 531, we get 8 and a remainder of 382.
Write down 8 as next digit of the result. 
Result so far: 187292.8
Subtract 4248 from 4630 to get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Going ahead to step 10:
531 can be fit into 3820 7 times, resulting in a remainder of 103.
Put 7 as the next digit of the answer. 
Result so far: 187292.87
If we subtract 3717 from 3820, we get 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Advancing to step 11:
When dividing 1030 by 531, we get 1 with a remainder of 499.
Write down 1 as next digit of the result. 
Result so far: 187292.871
The remainder is 499 after subtracting 531 from 1030.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Going ahead to step 12:
4990 divided by 531 is 9 with a remainder of 211.
Write down 9 as next digit of the result. 
Result so far: 187292.8719
Subtracting 4779 from 4990 leaves us with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Going ahead to step 13:
The number 531 fits into 2110 3 times, leaving a remainder of 517.
The next digit of our result is 3. 
Result so far: 187292.87193
Subtract 1593 from 2110 to get 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Let's proceed to step 14:
When dividing 5170 by 531, we get 9 with a remainder of 391.
Put 9 as the next digit of the answer. 
Result so far: 187292.871939
The remainder is 391 after subtracting 4779 from 5170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Step 15:
If we divide 3910 by 531, we get 7 and a remainder of 193.
Put 7 as the next digit of the answer. 
Result so far: 187292.8719397
Deduct 3717 from 3910 and we're left with 193.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1930, and continue the process.

Moving on to step 16:
531 can be fit into 1930 3 times, resulting in a remainder of 337.
Use 3 as the next digit of our solution. 
Result so far: 187292.87193973
If we subtract 1593 from 1930, we get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

The quotient of the division is 187292.87193973, and the remainder is 3.37e-07.
