43245303 divided by 171 
The aim is to understand the frequency of 171 in 43245303.

Advancing to step 1:
When dividing 4 by 171, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 171

On to step 2:
171 goes into 43 0 times with a remainder of 43.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Include the next digit (2) from the dividend after 43, then repeat: 432 / 171

On to step 3:
171 goes into 432 2 times with a remainder of 90.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 342 from 432 leaves us with 90.
Append the next digit (4) from the dividend to 90 and continue with: 904 / 171

On to step 4:
171 can be fit into 904 5 times, resulting in a remainder of 49.
The next digit of our result is 5. 
Result so far: 25.0
If we subtract 855 from 904, we get 49.
Bring next digit (5) of the dividend behind the 49 and repeat the process: 495 / 171

Moving on to step 5:
When dividing 495 by 171, we get 2 with a remainder of 153.
The next digit of our result is 2. 
Result so far: 252.0
Subtracting 342 from 495 leaves us with 153.
Take the next digit (3) from the dividend and append it to 153, then repeat: 1533 / 171

Moving on to step 6:
1533 divided by 171 is 8 with a remainder of 165.
The number 8 becomes the next digit in our result. 
Result so far: 2528.0
Subtracting 1368 from 1533 leaves us with 165.
Grab the next digit (0) from the dividend, add it to 165, then carry on: 1650 / 171

Step 7:
The number 171 fits into 1650 9 times, leaving a remainder of 111.
Record the quotient 9 as the next digit in the result. 
Result so far: 25289.0
Deduct 1539 from 1650 and we're left with 111.
Append the next digit (3) from the dividend to 111 and continue with: 1113 / 171

Step 8:
171 can be fit into 1113 6 times, resulting in a remainder of 87.
Put 6 as the next digit of the answer. 
Result so far: 252896.0
Subtracting 1026 from 1113 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Step 9:
171 goes into 870 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 252896.5
Deduct 855 from 870 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
171 goes into 150 0 times with a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 252896.5
If we take 0 away from 150, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Let's proceed to step 11:
If we divide 1500 by 171, we get 8 and a remainder of 132.
Use 8 as the next digit of our solution. 
Result so far: 252896.508
If we subtract 1368 from 1500, we get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Let's proceed to step 12:
When dividing 1320 by 171, we get 7 with a remainder of 123.
The next digit of our result is 7. 
Result so far: 252896.5087
If we take 1197 away from 1320, we end up with 123.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

On to step 13:
171 goes into 1230 7 times with a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 252896.50877
If we subtract 1197 from 1230, we get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

The quotient of the division is 252896.50877, and the remainder is 3.3e-05.
