Let's divide 20536842 by 424
The aim is to understand the frequency of 424 in 20536842.

Advancing to step 1:
If we divide 2 by 424, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 424

Let's proceed to step 2:
If we divide 20 by 424, we get 0 and a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 424

Let's proceed to step 3:
424 goes into 205 0 times with a remainder of 205.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 205 after subtracting 0 from 205.
Bring next digit (3) of the dividend behind the 205 and repeat the process: 2053 / 424

On to step 4:
When dividing 2053 by 424, we get 4 with a remainder of 357.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 1696 from 2053 and we're left with 357.
Include the next digit (6) from the dividend after 357, then repeat: 3576 / 424

Step 5:
424 goes into 3576 8 times with a remainder of 184.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
Subtract 3392 from 3576 to get 184.
Grab the next digit (8) from the dividend, add it to 184, then carry on: 1848 / 424

Step 6:
424 can be fit into 1848 4 times, resulting in a remainder of 152.
Record the quotient 4 as the next digit in the result. 
Result so far: 484.0
If we subtract 1696 from 1848, we get 152.
Fetch the next digit (4) from the dividend, attach it to 152 and continue: 1524 / 424

Let's proceed to step 7:
When dividing 1524 by 424, we get 3 with a remainder of 252.
The number 3 becomes the next digit in our result. 
Result so far: 4843.0
The remainder is 252 after subtracting 1272 from 1524.
Include the next digit (2) from the dividend after 252, then repeat: 2522 / 424

Let's proceed to step 8:
424 goes into 2522 5 times with a remainder of 402.
The next digit of our result is 5. 
Result so far: 48435.0
Subtracting 2120 from 2522 leaves us with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Let's proceed to step 9:
If we divide 4020 by 424, we get 9 and a remainder of 204.
The next digit of our result is 9. 
Result so far: 48435.9
The remainder is 204 after subtracting 3816 from 4020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Let's proceed to step 10:
When dividing 2040 by 424, we get 4 with a remainder of 344.
The number 4 becomes the next digit in our result. 
Result so far: 48435.94
If we take 1696 away from 2040, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 11:
424 goes into 3440 8 times with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 48435.948
Subtract 3392 from 3440 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 12:
When dividing 480 by 424, we get 1 with a remainder of 56.
The next digit of our result is 1. 
Result so far: 48435.9481
Subtract 424 from 480 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 13:
424 can be fit into 560 1 times, resulting in a remainder of 136.
Record the quotient 1 as the next digit in the result. 
Result so far: 48435.94811
Subtract 424 from 560 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The final result is 48435.94811 with a remainder of 0.000136.
