We look at the division of 23381814 by 442 
The aim is to understand the frequency of 442 in 23381814.

On to step 1:
442 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 442

On to step 2:
23 divided by 442 is 0 with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Fetch the next digit (3) from the dividend, attach it to 23 and continue: 233 / 442

Going ahead to step 3:
233 divided by 442 is 0 with a remainder of 233.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 233, we get 233.
Fetch the next digit (8) from the dividend, attach it to 233 and continue: 2338 / 442

On to step 4:
The number 442 fits into 2338 5 times, leaving a remainder of 128.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 2210 from 2338, we get 128.
Fetch the next digit (1) from the dividend, attach it to 128 and continue: 1281 / 442

Step 5:
The number 442 fits into 1281 2 times, leaving a remainder of 397.
The next digit of our result is 2. 
Result so far: 52.0
Subtracting 884 from 1281 leaves us with 397.
Bring next digit (8) of the dividend behind the 397 and repeat the process: 3978 / 442

Moving on to step 6:
The number 442 fits into 3978 9 times, leaving a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 529.0
If we subtract 3978 from 3978, we get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 442

Advancing to step 7:
When dividing 1 by 442, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 5290.0
If we take 0 away from 1, we end up with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 442

Moving on to step 8:
When dividing 14 by 442, we get 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 52900.0
If we subtract 0 from 14, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 9:
The number 442 fits into 140 0 times, leaving a remainder of 140.
Use 0 as the next digit of our solution. 
Result so far: 52900.0
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Moving on to step 10:
When dividing 1400 by 442, we get 3 with a remainder of 74.
Put 3 as the next digit of the answer. 
Result so far: 52900.03
The remainder is 74 after subtracting 1326 from 1400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 11:
The number 442 fits into 740 1 times, leaving a remainder of 298.
Write down 1 as next digit of the result. 
Result so far: 52900.031
Subtracting 442 from 740 leaves us with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

On to step 12:
If we divide 2980 by 442, we get 6 and a remainder of 328.
The number 6 becomes the next digit in our result. 
Result so far: 52900.0316
Subtract 2652 from 2980 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.

Moving on to step 13:
The number 442 fits into 3280 7 times, leaving a remainder of 186.
Use 7 as the next digit of our solution. 
Result so far: 52900.03167
If we subtract 3094 from 3280, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 14:
If we divide 1860 by 442, we get 4 and a remainder of 92.
The next digit of our result is 4. 
Result so far: 52900.031674
Deduct 1768 from 1860 and we're left with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Step 15:
920 divided by 442 is 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 52900.0316742
If we subtract 884 from 920, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 16:
360 divided by 442 is 0 with a remainder of 360.
Record the quotient 0 as the next digit in the result. 
Result so far: 52900.0316742
If we take 0 away from 360, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

After the division, we end up with 52900.0316742 and a remainder of 3.6e-07.
