Let's divide 76447568 by 531
The aim is to understand the frequency of 531 in 76447568.

Let's proceed to step 1:
The number 531 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 531

Let's proceed to step 2:
76 divided by 531 is 0 with a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 76 and we're left with 76.
Include the next digit (4) from the dividend after 76, then repeat: 764 / 531

Step 3:
If we divide 764 by 531, we get 1 and a remainder of 233.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 531 from 764 and we're left with 233.
Take the next digit (4) from the dividend and append it to 233, then repeat: 2334 / 531

Step 4:
When dividing 2334 by 531, we get 4 with a remainder of 210.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 2124 from 2334 and we're left with 210.
Bring next digit (7) of the dividend behind the 210 and repeat the process: 2107 / 531

Going ahead to step 5:
If we divide 2107 by 531, we get 3 and a remainder of 514.
Write down 3 as next digit of the result. 
Result so far: 143.0
The remainder is 514 after subtracting 1593 from 2107.
Take the next digit (5) from the dividend and append it to 514, then repeat: 5145 / 531

Moving on to step 6:
5145 divided by 531 is 9 with a remainder of 366.
Use 9 as the next digit of our solution. 
Result so far: 1439.0
If we take 4779 away from 5145, we end up with 366.
Include the next digit (6) from the dividend after 366, then repeat: 3666 / 531

Let's proceed to step 7:
3666 divided by 531 is 6 with a remainder of 480.
Record the quotient 6 as the next digit in the result. 
Result so far: 14396.0
Deduct 3186 from 3666 and we're left with 480.
Append the next digit (8) from the dividend to 480 and continue with: 4808 / 531

Going ahead to step 8:
When dividing 4808 by 531, we get 9 with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 143969.0
If we take 4779 away from 4808, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 9:
531 can be fit into 290 0 times, resulting in a remainder of 290.
The number 0 becomes the next digit in our result. 
Result so far: 143969.0
Subtract 0 from 290 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 10:
531 goes into 2900 5 times with a remainder of 245.
Record the quotient 5 as the next digit in the result. 
Result so far: 143969.05
If we take 2655 away from 2900, we end up with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 11:
531 can be fit into 2450 4 times, resulting in a remainder of 326.
The number 4 becomes the next digit in our result. 
Result so far: 143969.054
Subtract 2124 from 2450 to get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Step 12:
3260 divided by 531 is 6 with a remainder of 74.
Write down 6 as next digit of the result. 
Result so far: 143969.0546
Subtract 3186 from 3260 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 13:
The number 531 fits into 740 1 times, leaving a remainder of 209.
The number 1 becomes the next digit in our result. 
Result so far: 143969.05461
Subtracting 531 from 740 leaves us with 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

On to step 14:
531 goes into 2090 3 times with a remainder of 497.
Record the quotient 3 as the next digit in the result. 
Result so far: 143969.054613
Subtract 1593 from 2090 to get 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Step 15:
If we divide 4970 by 531, we get 9 and a remainder of 191.
The number 9 becomes the next digit in our result. 
Result so far: 143969.0546139
Subtract 4779 from 4970 to get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Advancing to step 16:
531 can be fit into 1910 3 times, resulting in a remainder of 317.
Use 3 as the next digit of our solution. 
Result so far: 143969.05461393
Subtract 1593 from 1910 to get 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

The final result is 143969.05461393 with a remainder of 3.17e-07.
