74910159 divided by 531 
The aim is to understand the frequency of 531 in 74910159.

Step 1:
The number 531 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 531

Step 2:
If we divide 74 by 531, we get 0 and a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 74 after subtracting 0 from 74.
Take the next digit (9) from the dividend and append it to 74, then repeat: 749 / 531

Going ahead to step 3:
749 divided by 531 is 1 with a remainder of 218.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 531 from 749, we get 218.
Append the next digit (1) from the dividend to 218 and continue with: 2181 / 531

Let's proceed to step 4:
531 goes into 2181 4 times with a remainder of 57.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 2124 from 2181 and we're left with 57.
Include the next digit (0) from the dividend after 57, then repeat: 570 / 531

Advancing to step 5:
531 can be fit into 570 1 times, resulting in a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 141.0
The remainder is 39 after subtracting 531 from 570.
Fetch the next digit (1) from the dividend, attach it to 39 and continue: 391 / 531

Going ahead to step 6:
531 can be fit into 391 0 times, resulting in a remainder of 391.
The next digit of our result is 0. 
Result so far: 1410.0
Subtract 0 from 391 to get 391.
Grab the next digit (5) from the dividend, add it to 391, then carry on: 3915 / 531

On to step 7:
531 can be fit into 3915 7 times, resulting in a remainder of 198.
Write down 7 as next digit of the result. 
Result so far: 14107.0
Subtracting 3717 from 3915 leaves us with 198.
Grab the next digit (9) from the dividend, add it to 198, then carry on: 1989 / 531

Let's proceed to step 8:
If we divide 1989 by 531, we get 3 and a remainder of 396.
Use 3 as the next digit of our solution. 
Result so far: 141073.0
If we subtract 1593 from 1989, we get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Let's proceed to step 9:
531 can be fit into 3960 7 times, resulting in a remainder of 243.
The next digit of our result is 7. 
Result so far: 141073.7
Subtract 3717 from 3960 to get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

On to step 10:
2430 divided by 531 is 4 with a remainder of 306.
Put 4 as the next digit of the answer. 
Result so far: 141073.74
Deduct 2124 from 2430 and we're left with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 11:
When dividing 3060 by 531, we get 5 with a remainder of 405.
Put 5 as the next digit of the answer. 
Result so far: 141073.745
Subtracting 2655 from 3060 leaves us with 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Advancing to step 12:
If we divide 4050 by 531, we get 7 and a remainder of 333.
Write down 7 as next digit of the result. 
Result so far: 141073.7457
If we take 3717 away from 4050, we end up with 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3330, and continue the process.

On to step 13:
When dividing 3330 by 531, we get 6 with a remainder of 144.
Record the quotient 6 as the next digit in the result. 
Result so far: 141073.74576
If we take 3186 away from 3330, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Step 14:
The number 531 fits into 1440 2 times, leaving a remainder of 378.
Record the quotient 2 as the next digit in the result. 
Result so far: 141073.745762
The remainder is 378 after subtracting 1062 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Let's proceed to step 15:
When dividing 3780 by 531, we get 7 with a remainder of 63.
The next digit of our result is 7. 
Result so far: 141073.7457627
If we subtract 3717 from 3780, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 16:
If we divide 630 by 531, we get 1 and a remainder of 99.
Write down 1 as next digit of the result. 
Result so far: 141073.74576271
If we take 531 away from 630, we end up with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

The final result is 141073.74576271 with a remainder of 9.9e-08.
