104548 ÷ 42 
The aim is to understand the frequency of 42 in 104548.

Step 1:
1 divided by 42 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 42

Going ahead to step 2:
If we divide 10 by 42, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 10, we get 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 42

Going ahead to step 3:
The number 42 fits into 104 2 times, leaving a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 84 from 104 to get 20.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 42

On to step 4:
If we divide 205 by 42, we get 4 and a remainder of 37.
Use 4 as the next digit of our solution. 
Result so far: 24.0
Deduct 168 from 205 and we're left with 37.
Fetch the next digit (4) from the dividend, attach it to 37 and continue: 374 / 42

On to step 5:
The number 42 fits into 374 8 times, leaving a remainder of 38.
Put 8 as the next digit of the answer. 
Result so far: 248.0
If we take 336 away from 374, we end up with 38.
Include the next digit (8) from the dividend after 38, then repeat: 388 / 42

On to step 6:
If we divide 388 by 42, we get 9 and a remainder of 10.
The next digit of our result is 9. 
Result so far: 2489.0
Deduct 378 from 388 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
When dividing 100 by 42, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 2489.2
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 8:
If we divide 160 by 42, we get 3 and a remainder of 34.
Record the quotient 3 as the next digit in the result. 
Result so far: 2489.23
Deduct 126 from 160 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 9:
340 divided by 42 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 2489.238
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
If we divide 40 by 42, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 2489.238
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
When dividing 400 by 42, we get 9 with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 2489.23809
Deduct 378 from 400 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
When dividing 220 by 42, we get 5 with a remainder of 10.
The next digit of our result is 5. 
Result so far: 2489.238095
Subtract 210 from 220 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 13:
42 can be fit into 100 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 2489.2380952
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
If we divide 160 by 42, we get 3 and a remainder of 34.
The next digit of our result is 3. 
Result so far: 2489.23809523
If we subtract 126 from 160, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final outcome is 2489.23809523, with a leftover of 3.4e-08.
