43057254 ÷ 289 
The aim is to understand the frequency of 289 in 43057254.

Going ahead to step 1:
289 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 289

Let's proceed to step 2:
The number 289 fits into 43 0 times, leaving a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 43, we end up with 43.
Take the next digit (0) from the dividend and append it to 43, then repeat: 430 / 289

Going ahead to step 3:
430 divided by 289 is 1 with a remainder of 141.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 289 from 430 to get 141.
Take the next digit (5) from the dividend and append it to 141, then repeat: 1415 / 289

Let's proceed to step 4:
289 can be fit into 1415 4 times, resulting in a remainder of 259.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 259 after subtracting 1156 from 1415.
Take the next digit (7) from the dividend and append it to 259, then repeat: 2597 / 289

On to step 5:
2597 divided by 289 is 8 with a remainder of 285.
The number 8 becomes the next digit in our result. 
Result so far: 148.0
Subtracting 2312 from 2597 leaves us with 285.
Bring next digit (2) of the dividend behind the 285 and repeat the process: 2852 / 289

Going ahead to step 6:
When dividing 2852 by 289, we get 9 with a remainder of 251.
Record the quotient 9 as the next digit in the result. 
Result so far: 1489.0
Subtracting 2601 from 2852 leaves us with 251.
Append the next digit (5) from the dividend to 251 and continue with: 2515 / 289

Advancing to step 7:
If we divide 2515 by 289, we get 8 and a remainder of 203.
Record the quotient 8 as the next digit in the result. 
Result so far: 14898.0
Deduct 2312 from 2515 and we're left with 203.
Grab the next digit (4) from the dividend, add it to 203, then carry on: 2034 / 289

Moving on to step 8:
The number 289 fits into 2034 7 times, leaving a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 148987.0
Subtract 2023 from 2034 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
If we divide 110 by 289, we get 0 and a remainder of 110.
Write down 0 as next digit of the result. 
Result so far: 148987.0
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 10:
If we divide 1100 by 289, we get 3 and a remainder of 233.
Write down 3 as next digit of the result. 
Result so far: 148987.03
Deduct 867 from 1100 and we're left with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

Advancing to step 11:
If we divide 2330 by 289, we get 8 and a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 148987.038
If we take 2312 away from 2330, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 12:
The number 289 fits into 180 0 times, leaving a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 148987.038
If we take 0 away from 180, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 13:
The number 289 fits into 1800 6 times, leaving a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 148987.03806
If we subtract 1734 from 1800, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 14:
If we divide 660 by 289, we get 2 and a remainder of 82.
The number 2 becomes the next digit in our result. 
Result so far: 148987.038062
Subtract 578 from 660 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Step 15:
If we divide 820 by 289, we get 2 and a remainder of 242.
Record the quotient 2 as the next digit in the result. 
Result so far: 148987.0380622
If we take 578 away from 820, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Our division results in 148987.0380622 with a remaining 2.42e-06.
