13233857 divided by 442 
The aim is to understand the frequency of 442 in 13233857.

Going ahead to step 1:
If we divide 1 by 442, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 442

Going ahead to step 2:
442 goes into 13 0 times with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Grab the next digit (2) from the dividend, add it to 13, then carry on: 132 / 442

Step 3:
The number 442 fits into 132 0 times, leaving a remainder of 132.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 132 to get 132.
Bring next digit (3) of the dividend behind the 132 and repeat the process: 1323 / 442

Moving on to step 4:
The number 442 fits into 1323 2 times, leaving a remainder of 439.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 884 from 1323 to get 439.
Grab the next digit (3) from the dividend, add it to 439, then carry on: 4393 / 442

Step 5:
4393 divided by 442 is 9 with a remainder of 415.
The number 9 becomes the next digit in our result. 
Result so far: 29.0
If we subtract 3978 from 4393, we get 415.
Bring next digit (8) of the dividend behind the 415 and repeat the process: 4158 / 442

Moving on to step 6:
If we divide 4158 by 442, we get 9 and a remainder of 180.
The number 9 becomes the next digit in our result. 
Result so far: 299.0
If we take 3978 away from 4158, we end up with 180.
Bring next digit (5) of the dividend behind the 180 and repeat the process: 1805 / 442

Let's proceed to step 7:
1805 divided by 442 is 4 with a remainder of 37.
The next digit of our result is 4. 
Result so far: 2994.0
Subtract 1768 from 1805 to get 37.
Append the next digit (7) from the dividend to 37 and continue with: 377 / 442

Advancing to step 8:
377 divided by 442 is 0 with a remainder of 377.
Record the quotient 0 as the next digit in the result. 
Result so far: 29940.0
Subtract 0 from 377 to get 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Step 9:
When dividing 3770 by 442, we get 8 with a remainder of 234.
Put 8 as the next digit of the answer. 
Result so far: 29940.8
The remainder is 234 after subtracting 3536 from 3770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Advancing to step 10:
The number 442 fits into 2340 5 times, leaving a remainder of 130.
The number 5 becomes the next digit in our result. 
Result so far: 29940.85
If we subtract 2210 from 2340, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 11:
442 goes into 1300 2 times with a remainder of 416.
Use 2 as the next digit of our solution. 
Result so far: 29940.852
Deduct 884 from 1300 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Going ahead to step 12:
If we divide 4160 by 442, we get 9 and a remainder of 182.
Put 9 as the next digit of the answer. 
Result so far: 29940.8529
If we subtract 3978 from 4160, we get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Let's proceed to step 13:
442 goes into 1820 4 times with a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 29940.85294
Subtract 1768 from 1820 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 14:
442 can be fit into 520 1 times, resulting in a remainder of 78.
Write down 1 as next digit of the result. 
Result so far: 29940.852941
Subtract 442 from 520 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 15:
442 can be fit into 780 1 times, resulting in a remainder of 338.
The number 1 becomes the next digit in our result. 
Result so far: 29940.8529411
If we take 442 away from 780, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

The quotient of the division is 29940.8529411, and the remainder is 3.38e-06.
