Let's divide 39165906 by 43
The aim is to understand the frequency of 43 in 39165906.

Moving on to step 1:
If we divide 3 by 43, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 43

Step 2:
The number 43 fits into 39 0 times, leaving a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 43

Let's proceed to step 3:
43 goes into 391 9 times with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 4 after subtracting 387 from 391.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 43

Advancing to step 4:
If we divide 46 by 43, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 91.0
If we subtract 43 from 46, we get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 43

Step 5:
When dividing 35 by 43, we get 0 with a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 910.0
Deduct 0 from 35 and we're left with 35.
Include the next digit (9) from the dividend after 35, then repeat: 359 / 43

On to step 6:
359 divided by 43 is 8 with a remainder of 15.
Put 8 as the next digit of the answer. 
Result so far: 9108.0
Subtracting 344 from 359 leaves us with 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 43

Advancing to step 7:
The number 43 fits into 150 3 times, leaving a remainder of 21.
The next digit of our result is 3. 
Result so far: 91083.0
If we take 129 away from 150, we end up with 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 43

Step 8:
43 goes into 216 5 times with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 910835.0
Subtracting 215 from 216 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
10 divided by 43 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 910835.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
43 can be fit into 100 2 times, resulting in a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 910835.02
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
140 divided by 43 is 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 910835.023
Deduct 129 from 140 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 12:
43 can be fit into 110 2 times, resulting in a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 910835.0232
If we subtract 86 from 110, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
43 can be fit into 240 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 910835.02325
The remainder is 25 after subtracting 215 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 14:
43 goes into 250 5 times with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 910835.023255
The remainder is 35 after subtracting 215 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 910835.023255 with a remainder of 3.5e-06.
