We're dividing 40438042 by 302 
The aim is to understand the frequency of 302 in 40438042.

Let's proceed to step 1:
If we divide 4 by 302, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 302

Going ahead to step 2:
The number 302 fits into 40 0 times, leaving a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Take the next digit (4) from the dividend and append it to 40, then repeat: 404 / 302

Moving on to step 3:
The number 302 fits into 404 1 times, leaving a remainder of 102.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 302 from 404 and we're left with 102.
Include the next digit (3) from the dividend after 102, then repeat: 1023 / 302

Moving on to step 4:
When dividing 1023 by 302, we get 3 with a remainder of 117.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Deduct 906 from 1023 and we're left with 117.
Grab the next digit (8) from the dividend, add it to 117, then carry on: 1178 / 302

Let's proceed to step 5:
If we divide 1178 by 302, we get 3 and a remainder of 272.
Put 3 as the next digit of the answer. 
Result so far: 133.0
If we subtract 906 from 1178, we get 272.
Fetch the next digit (0) from the dividend, attach it to 272 and continue: 2720 / 302

On to step 6:
302 goes into 2720 9 times with a remainder of 2.
The next digit of our result is 9. 
Result so far: 1339.0
Deduct 2718 from 2720 and we're left with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 302

Step 7:
The number 302 fits into 24 0 times, leaving a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 13390.0
The remainder is 24 after subtracting 0 from 24.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 302

Step 8:
The number 302 fits into 242 0 times, leaving a remainder of 242.
Use 0 as the next digit of our solution. 
Result so far: 133900.0
The remainder is 242 after subtracting 0 from 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Let's proceed to step 9:
302 goes into 2420 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 133900.8
Subtracting 2416 from 2420 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
302 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 133900.8
If we take 0 away from 40, we end up 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.

Let's proceed to step 11:
302 goes into 400 1 times with a remainder of 98.
Put 1 as the next digit of the answer. 
Result so far: 133900.801
The remainder is 98 after subtracting 302 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

On to step 12:
302 goes into 980 3 times with a remainder of 74.
Put 3 as the next digit of the answer. 
Result so far: 133900.8013
If we take 906 away from 980, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 13:
740 divided by 302 is 2 with a remainder of 136.
The next digit of our result is 2. 
Result so far: 133900.80132
Subtracting 604 from 740 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 14:
If we divide 1360 by 302, we get 4 and a remainder of 152.
The number 4 becomes the next digit in our result. 
Result so far: 133900.801324
If we subtract 1208 from 1360, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 15:
302 can be fit into 1520 5 times, resulting in a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 133900.8013245
If we subtract 1510 from 1520, we 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.

Advancing to step 16:
The number 302 fits into 100 0 times, leaving a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 133900.8013245
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 133900.8013245 with a remainder of 1e-07.
