Let's divide 1843405 by 442
The aim is to understand the frequency of 442 in 1843405.

Step 1:
The number 442 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 442

Step 2:
If we divide 18 by 442, we get 0 and a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (4) of the dividend behind the 18 and repeat the process: 184 / 442

Let's proceed to step 3:
442 goes into 184 0 times with a remainder of 184.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 184 leaves us with 184.
Take the next digit (3) from the dividend and append it to 184, then repeat: 1843 / 442

Step 4:
If we divide 1843 by 442, we get 4 and a remainder of 75.
The next digit of our result is 4. 
Result so far: 4.0
If we take 1768 away from 1843, we end up with 75.
Bring next digit (4) of the dividend behind the 75 and repeat the process: 754 / 442

On to step 5:
754 divided by 442 is 1 with a remainder of 312.
Put 1 as the next digit of the answer. 
Result so far: 41.0
The remainder is 312 after subtracting 442 from 754.
Fetch the next digit (0) from the dividend, attach it to 312 and continue: 3120 / 442

On to step 6:
If we divide 3120 by 442, we get 7 and a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 417.0
Deduct 3094 from 3120 and we're left with 26.
Append the next digit (5) from the dividend to 26 and continue with: 265 / 442

Step 7:
442 can be fit into 265 0 times, resulting in a remainder of 265.
Use 0 as the next digit of our solution. 
Result so far: 4170.0
If we take 0 away from 265, we end up with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Going ahead to step 8:
When dividing 2650 by 442, we get 5 with a remainder of 440.
The next digit of our result is 5. 
Result so far: 4170.5
If we subtract 2210 from 2650, we get 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 9:
When dividing 4400 by 442, we get 9 with a remainder of 422.
Record the quotient 9 as the next digit in the result. 
Result so far: 4170.59
If we subtract 3978 from 4400, we get 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

On to step 10:
442 can be fit into 4220 9 times, resulting in a remainder of 242.
Record the quotient 9 as the next digit in the result. 
Result so far: 4170.599
Subtract 3978 from 4220 to get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

The final result is 4170.599 with a remainder of 0.0242.
