We're dividing 42542138 by 524 
The aim is to understand the frequency of 524 in 42542138.

Let's proceed to step 1:
524 goes into 4 0 times 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 (2) of the dividend behind the 4 and repeat the process: 42 / 524

Let's proceed to step 2:
524 goes into 42 0 times with a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 42 leaves us with 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 524

Moving on to step 3:
When dividing 425 by 524, we get 0 with a remainder of 425.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 425 and we're left with 425.
Bring next digit (4) of the dividend behind the 425 and repeat the process: 4254 / 524

Let's proceed to step 4:
The number 524 fits into 4254 8 times, leaving a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 62 after subtracting 4192 from 4254.
Append the next digit (2) from the dividend to 62 and continue with: 622 / 524

Advancing to step 5:
524 can be fit into 622 1 times, resulting in a remainder of 98.
Put 1 as the next digit of the answer. 
Result so far: 81.0
Deduct 524 from 622 and we're left with 98.
Include the next digit (1) from the dividend after 98, then repeat: 981 / 524

On to step 6:
When dividing 981 by 524, we get 1 with a remainder of 457.
Put 1 as the next digit of the answer. 
Result so far: 811.0
The remainder is 457 after subtracting 524 from 981.
Bring next digit (3) of the dividend behind the 457 and repeat the process: 4573 / 524

Moving on to step 7:
The number 524 fits into 4573 8 times, leaving a remainder of 381.
Record the quotient 8 as the next digit in the result. 
Result so far: 8118.0
Subtracting 4192 from 4573 leaves us with 381.
Take the next digit (8) from the dividend and append it to 381, then repeat: 3818 / 524

On to step 8:
When dividing 3818 by 524, we get 7 with a remainder of 150.
Put 7 as the next digit of the answer. 
Result so far: 81187.0
If we take 3668 away from 3818, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Moving on to step 9:
1500 divided by 524 is 2 with a remainder of 452.
The number 2 becomes the next digit in our result. 
Result so far: 81187.2
If we take 1048 away from 1500, we end up with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Going ahead to step 10:
524 goes into 4520 8 times with a remainder of 328.
Record the quotient 8 as the next digit in the result. 
Result so far: 81187.28
Subtract 4192 from 4520 to get 328.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3280, and continue the process.

Going ahead to step 11:
If we divide 3280 by 524, we get 6 and a remainder of 136.
The number 6 becomes the next digit in our result. 
Result so far: 81187.286
Subtracting 3144 from 3280 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Let's proceed to step 12:
If we divide 1360 by 524, we get 2 and a remainder of 312.
Record the quotient 2 as the next digit in the result. 
Result so far: 81187.2862
If we subtract 1048 from 1360, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Going ahead to step 13:
524 can be fit into 3120 5 times, resulting in a remainder of 500.
Record the quotient 5 as the next digit in the result. 
Result so far: 81187.28625
If we take 2620 away from 3120, we end up with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Advancing to step 14:
When dividing 5000 by 524, we get 9 with a remainder of 284.
Use 9 as the next digit of our solution. 
Result so far: 81187.286259
Deduct 4716 from 5000 and we're left with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Advancing to step 15:
When dividing 2840 by 524, we get 5 with a remainder of 220.
Write down 5 as next digit of the result. 
Result so far: 81187.2862595
If we take 2620 away from 2840, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 16:
524 goes into 2200 4 times with a remainder of 104.
Write down 4 as next digit of the result. 
Result so far: 81187.28625954
If we subtract 2096 from 2200, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

The quotient of the division is 81187.28625954, and the remainder is 1.04e-07.
