We're dividing 42423798 by 331 
The aim is to understand the frequency of 331 in 42423798.

Advancing to step 1:
331 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 331

Let's proceed to step 2:
If we divide 42 by 331, we get 0 and a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Fetch the next digit (4) from the dividend, attach it to 42 and continue: 424 / 331

Advancing to step 3:
The number 331 fits into 424 1 times, leaving a remainder of 93.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 331 from 424, we get 93.
Take the next digit (2) from the dividend and append it to 93, then repeat: 932 / 331

Going ahead to step 4:
331 can be fit into 932 2 times, resulting in a remainder of 270.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we subtract 662 from 932, we get 270.
Append the next digit (3) from the dividend to 270 and continue with: 2703 / 331

Step 5:
The number 331 fits into 2703 8 times, leaving a remainder of 55.
Record the quotient 8 as the next digit in the result. 
Result so far: 128.0
The remainder is 55 after subtracting 2648 from 2703.
Bring next digit (7) of the dividend behind the 55 and repeat the process: 557 / 331

On to step 6:
If we divide 557 by 331, we get 1 and a remainder of 226.
Write down 1 as next digit of the result. 
Result so far: 1281.0
If we subtract 331 from 557, we get 226.
Include the next digit (9) from the dividend after 226, then repeat: 2269 / 331

On to step 7:
331 goes into 2269 6 times with a remainder of 283.
Record the quotient 6 as the next digit in the result. 
Result so far: 12816.0
The remainder is 283 after subtracting 1986 from 2269.
Bring next digit (8) of the dividend behind the 283 and repeat the process: 2838 / 331

Let's proceed to step 8:
The number 331 fits into 2838 8 times, leaving a remainder of 190.
Put 8 as the next digit of the answer. 
Result so far: 128168.0
Subtracting 2648 from 2838 leaves us with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Step 9:
The number 331 fits into 1900 5 times, leaving a remainder of 245.
Write down 5 as next digit of the result. 
Result so far: 128168.5
Subtract 1655 from 1900 to get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Step 10:
The number 331 fits into 2450 7 times, leaving a remainder of 133.
Put 7 as the next digit of the answer. 
Result so far: 128168.57
Deduct 2317 from 2450 and we're left with 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Advancing to step 11:
If we divide 1330 by 331, we get 4 and a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 128168.574
Subtracting 1324 from 1330 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 12:
331 goes into 60 0 times with a remainder of 60.
The next digit of our result is 0. 
Result so far: 128168.574
Subtracting 0 from 60 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 13:
When dividing 600 by 331, we get 1 with a remainder of 269.
The number 1 becomes the next digit in our result. 
Result so far: 128168.57401
Deduct 331 from 600 and we're left with 269.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2690, and continue the process.

Advancing to step 14:
If we divide 2690 by 331, we get 8 and a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 128168.574018
The remainder is 42 after subtracting 2648 from 2690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 15:
331 goes into 420 1 times with a remainder of 89.
The number 1 becomes the next digit in our result. 
Result so far: 128168.5740181
If we subtract 331 from 420, we get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Moving on to step 16:
If we divide 890 by 331, we get 2 and a remainder of 228.
Record the quotient 2 as the next digit in the result. 
Result so far: 128168.57401812
Subtract 662 from 890 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

In conclusion, the division gives 128168.57401812 with a balance of 2.28e-07.
