We look at the division of 50482345 by 523 
The aim is to understand the frequency of 523 in 50482345.

Going ahead to step 1:
523 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 523

Going ahead to step 2:
523 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Include the next digit (4) from the dividend after 50, then repeat: 504 / 523

Let's proceed to step 3:
The number 523 fits into 504 0 times, leaving a remainder of 504.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 504 leaves us with 504.
Fetch the next digit (8) from the dividend, attach it to 504 and continue: 5048 / 523

Step 4:
If we divide 5048 by 523, we get 9 and a remainder of 341.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 341 after subtracting 4707 from 5048.
Append the next digit (2) from the dividend to 341 and continue with: 3412 / 523

On to step 5:
When dividing 3412 by 523, we get 6 with a remainder of 274.
Use 6 as the next digit of our solution. 
Result so far: 96.0
If we subtract 3138 from 3412, we get 274.
Take the next digit (3) from the dividend and append it to 274, then repeat: 2743 / 523

Going ahead to step 6:
If we divide 2743 by 523, we get 5 and a remainder of 128.
The next digit of our result is 5. 
Result so far: 965.0
The remainder is 128 after subtracting 2615 from 2743.
Grab the next digit (4) from the dividend, add it to 128, then carry on: 1284 / 523

Going ahead to step 7:
523 can be fit into 1284 2 times, resulting in a remainder of 238.
The next digit of our result is 2. 
Result so far: 9652.0
Subtract 1046 from 1284 to get 238.
Include the next digit (5) from the dividend after 238, then repeat: 2385 / 523

Step 8:
When dividing 2385 by 523, we get 4 with a remainder of 293.
Put 4 as the next digit of the answer. 
Result so far: 96524.0
Subtracting 2092 from 2385 leaves us with 293.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

Going ahead to step 9:
523 can be fit into 2930 5 times, resulting in a remainder of 315.
The number 5 becomes the next digit in our result. 
Result so far: 96524.5
Subtracting 2615 from 2930 leaves us with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Advancing to step 10:
If we divide 3150 by 523, we get 6 and a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 96524.56
Deduct 3138 from 3150 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
523 goes into 120 0 times with a remainder of 120.
The number 0 becomes the next digit in our result. 
Result so far: 96524.56
The remainder is 120 after subtracting 0 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 12:
523 can be fit into 1200 2 times, resulting in a remainder of 154.
Write down 2 as next digit of the result. 
Result so far: 96524.5602
Subtract 1046 from 1200 to get 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Step 13:
The number 523 fits into 1540 2 times, leaving a remainder of 494.
Put 2 as the next digit of the answer. 
Result so far: 96524.56022
Subtract 1046 from 1540 to get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

After the division, we end up with 96524.56022 and a remainder of 0.000494.
