Let's divide 103353 by 42
The aim is to understand the frequency of 42 in 103353.

Moving on to step 1:
42 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 42

On to step 2:
42 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 42

Moving on to step 3:
42 can be fit into 103 2 times, resulting in a remainder of 19.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 84 from 103 and we're left with 19.
Fetch the next digit (3) from the dividend, attach it to 19 and continue: 193 / 42

Moving on to step 4:
The number 42 fits into 193 4 times, leaving a remainder of 25.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we take 168 away from 193, we end up with 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 42

Advancing to step 5:
If we divide 255 by 42, we get 6 and a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 246.0
The remainder is 3 after subtracting 252 from 255.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 42

Step 6:
42 can be fit into 33 0 times, resulting in a remainder of 33.
The number 0 becomes the next digit in our result. 
Result so far: 2460.0
Deduct 0 from 33 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 7:
When dividing 330 by 42, we get 7 with a remainder of 36.
Use 7 as the next digit of our solution. 
Result so far: 2460.7
Deduct 294 from 330 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 8:
42 can be fit into 360 8 times, resulting in a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 2460.78
Subtracting 336 from 360 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
If we divide 240 by 42, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 2460.785
Deduct 210 from 240 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
If we divide 300 by 42, we get 7 and a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 2460.7857
The remainder is 6 after subtracting 294 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 11:
42 goes into 60 1 times with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 2460.78571
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 12:
When dividing 180 by 42, we get 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 2460.785714
Subtracting 168 from 180 leaves us 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.

Going ahead to step 13:
120 divided by 42 is 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 2460.7857142
Deduct 84 from 120 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 14:
When dividing 360 by 42, we get 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 2460.78571428
Subtracting 336 from 360 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 2460.78571428 with a remaining 2.4e-08.
