We look at the division of 47866294 by 531 
The aim is to understand the frequency of 531 in 47866294.

On to step 1:
When dividing 4 by 531, we get 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 531

On to step 2:
If we divide 47 by 531, we get 0 and a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 47, we end up with 47.
Fetch the next digit (8) from the dividend, attach it to 47 and continue: 478 / 531

Advancing to step 3:
531 can be fit into 478 0 times, resulting in a remainder of 478.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 478 and we're left with 478.
Fetch the next digit (6) from the dividend, attach it to 478 and continue: 4786 / 531

Step 4:
4786 divided by 531 is 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 4779 from 4786, we get 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 531

Moving on to step 5:
When dividing 76 by 531, we get 0 with a remainder of 76.
The next digit of our result is 0. 
Result so far: 90.0
Subtracting 0 from 76 leaves us with 76.
Append the next digit (2) from the dividend to 76 and continue with: 762 / 531

Going ahead to step 6:
531 goes into 762 1 times with a remainder of 231.
Write down 1 as next digit of the result. 
Result so far: 901.0
Subtract 531 from 762 to get 231.
Append the next digit (9) from the dividend to 231 and continue with: 2319 / 531

Going ahead to step 7:
If we divide 2319 by 531, we get 4 and a remainder of 195.
Use 4 as the next digit of our solution. 
Result so far: 9014.0
If we take 2124 away from 2319, we end up with 195.
Fetch the next digit (4) from the dividend, attach it to 195 and continue: 1954 / 531

On to step 8:
The number 531 fits into 1954 3 times, leaving a remainder of 361.
Write down 3 as next digit of the result. 
Result so far: 90143.0
Subtracting 1593 from 1954 leaves us with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Advancing to step 9:
3610 divided by 531 is 6 with a remainder of 424.
Put 6 as the next digit of the answer. 
Result so far: 90143.6
Subtracting 3186 from 3610 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Let's proceed to step 10:
When dividing 4240 by 531, we get 7 with a remainder of 523.
The number 7 becomes the next digit in our result. 
Result so far: 90143.67
If we take 3717 away from 4240, we end up with 523.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Going ahead to step 11:
5230 divided by 531 is 9 with a remainder of 451.
Use 9 as the next digit of our solution. 
Result so far: 90143.679
Deduct 4779 from 5230 and we're left with 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

On to step 12:
531 goes into 4510 8 times with a remainder of 262.
The next digit of our result is 8. 
Result so far: 90143.6798
Subtracting 4248 from 4510 leaves us with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Going ahead to step 13:
2620 divided by 531 is 4 with a remainder of 496.
The number 4 becomes the next digit in our result. 
Result so far: 90143.67984
Subtracting 2124 from 2620 leaves us with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 14:
531 can be fit into 4960 9 times, resulting in a remainder of 181.
Use 9 as the next digit of our solution. 
Result so far: 90143.679849
Subtracting 4779 from 4960 leaves us with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

On to step 15:
The number 531 fits into 1810 3 times, leaving a remainder of 217.
Record the quotient 3 as the next digit in the result. 
Result so far: 90143.6798493
If we take 1593 away from 1810, we end up with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

On to step 16:
When dividing 2170 by 531, we get 4 with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 90143.67984934
Subtract 2124 from 2170 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Our division results in 90143.67984934 with a remaining 4.6e-08.
