Let's divide 43242954 by 397
The aim is to understand the frequency of 397 in 43242954.

On to step 1:
397 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 397

On to step 2:
397 can be fit into 43 0 times, resulting in a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Take the next digit (2) from the dividend and append it to 43, then repeat: 432 / 397

Advancing to step 3:
432 divided by 397 is 1 with a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 397 from 432, we get 35.
Take the next digit (4) from the dividend and append it to 35, then repeat: 354 / 397

Moving on to step 4:
354 divided by 397 is 0 with a remainder of 354.
The next digit of our result is 0. 
Result so far: 10.0
If we subtract 0 from 354, we get 354.
Bring next digit (2) of the dividend behind the 354 and repeat the process: 3542 / 397

Let's proceed to step 5:
3542 divided by 397 is 8 with a remainder of 366.
The next digit of our result is 8. 
Result so far: 108.0
Subtracting 3176 from 3542 leaves us with 366.
Append the next digit (9) from the dividend to 366 and continue with: 3669 / 397

On to step 6:
The number 397 fits into 3669 9 times, leaving a remainder of 96.
Put 9 as the next digit of the answer. 
Result so far: 1089.0
If we take 3573 away from 3669, we end up with 96.
Grab the next digit (5) from the dividend, add it to 96, then carry on: 965 / 397

Advancing to step 7:
965 divided by 397 is 2 with a remainder of 171.
The number 2 becomes the next digit in our result. 
Result so far: 10892.0
Subtracting 794 from 965 leaves us with 171.
Fetch the next digit (4) from the dividend, attach it to 171 and continue: 1714 / 397

Let's proceed to step 8:
397 can be fit into 1714 4 times, resulting in a remainder of 126.
Record the quotient 4 as the next digit in the result. 
Result so far: 108924.0
The remainder is 126 after subtracting 1588 from 1714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 9:
If we divide 1260 by 397, we get 3 and a remainder of 69.
The number 3 becomes the next digit in our result. 
Result so far: 108924.3
The remainder is 69 after subtracting 1191 from 1260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 10:
If we divide 690 by 397, we get 1 and a remainder of 293.
Write down 1 as next digit of the result. 
Result so far: 108924.31
The remainder is 293 after subtracting 397 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2930, and continue the process.

On to step 11:
The number 397 fits into 2930 7 times, leaving a remainder of 151.
Use 7 as the next digit of our solution. 
Result so far: 108924.317
Subtract 2779 from 2930 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

Going ahead to step 12:
397 can be fit into 1510 3 times, resulting in a remainder of 319.
Put 3 as the next digit of the answer. 
Result so far: 108924.3173
Deduct 1191 from 1510 and we're left with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Advancing to step 13:
3190 divided by 397 is 8 with a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 108924.31738
Deduct 3176 from 3190 and we're left with 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 14:
397 goes into 140 0 times with a remainder of 140.
The number 0 becomes the next digit in our result. 
Result so far: 108924.31738
If we subtract 0 from 140, we get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 15:
The number 397 fits into 1400 3 times, leaving a remainder of 209.
The next digit of our result is 3. 
Result so far: 108924.3173803
If we subtract 1191 from 1400, we get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Step 16:
397 can be fit into 2090 5 times, resulting in a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 108924.31738035
The remainder is 105 after subtracting 1985 from 2090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The quotient of the division is 108924.31738035, and the remainder is 1.05e-07.
