We look at the division of 44142093 by 523 
The aim is to understand the frequency of 523 in 44142093.

Let's proceed to step 1:
523 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 523

On to step 2:
44 divided by 523 is 0 with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 44 to get 44.
Append the next digit (1) from the dividend to 44 and continue with: 441 / 523

Moving on to step 3:
523 goes into 441 0 times with a remainder of 441.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 441 leaves us with 441.
Append the next digit (4) from the dividend to 441 and continue with: 4414 / 523

Advancing to step 4:
If we divide 4414 by 523, we get 8 and a remainder of 230.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we subtract 4184 from 4414, we get 230.
Grab the next digit (2) from the dividend, add it to 230, then carry on: 2302 / 523

Moving on to step 5:
523 can be fit into 2302 4 times, resulting in a remainder of 210.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Deduct 2092 from 2302 and we're left with 210.
Include the next digit (0) from the dividend after 210, then repeat: 2100 / 523

Advancing to step 6:
523 can be fit into 2100 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 844.0
Deduct 2092 from 2100 and we're left with 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 523

Going ahead to step 7:
If we divide 89 by 523, we get 0 and a remainder of 89.
The next digit of our result is 0. 
Result so far: 8440.0
Deduct 0 from 89 and we're left with 89.
Fetch the next digit (3) from the dividend, attach it to 89 and continue: 893 / 523

Moving on to step 8:
523 goes into 893 1 times with a remainder of 370.
The next digit of our result is 1. 
Result so far: 84401.0
If we take 523 away from 893, we end up with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 9:
If we divide 3700 by 523, we get 7 and a remainder of 39.
The next digit of our result is 7. 
Result so far: 84401.7
If we subtract 3661 from 3700, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 10:
523 can be fit into 390 0 times, resulting in a remainder of 390.
Write down 0 as next digit of the result. 
Result so far: 84401.7
Subtracting 0 from 390 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Let's proceed to step 11:
3900 divided by 523 is 7 with a remainder of 239.
Use 7 as the next digit of our solution. 
Result so far: 84401.707
If we subtract 3661 from 3900, we get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Step 12:
If we divide 2390 by 523, we get 4 and a remainder of 298.
Put 4 as the next digit of the answer. 
Result so far: 84401.7074
If we subtract 2092 from 2390, we get 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Step 13:
When dividing 2980 by 523, we get 5 with a remainder of 365.
The number 5 becomes the next digit in our result. 
Result so far: 84401.70745
Subtract 2615 from 2980 to get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Let's proceed to step 14:
523 goes into 3650 6 times with a remainder of 512.
Write down 6 as next digit of the result. 
Result so far: 84401.707456
The remainder is 512 after subtracting 3138 from 3650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

On to step 15:
If we divide 5120 by 523, we get 9 and a remainder of 413.
Put 9 as the next digit of the answer. 
Result so far: 84401.7074569
If we take 4707 away from 5120, we end up with 413.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4130, and continue the process.

Advancing to step 16:
4130 divided by 523 is 7 with a remainder of 469.
Put 7 as the next digit of the answer. 
Result so far: 84401.70745697
Subtracting 3661 from 4130 leaves us with 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

After the division, we end up with 84401.70745697 and a remainder of 4.69e-07.
