64254990 divided by 43 
The aim is to understand the frequency of 43 in 64254990.

On to step 1:
The number 43 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 43

Advancing to step 2:
When dividing 64 by 43, we get 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 43 from 64, we get 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 43

Let's proceed to step 3:
43 goes into 212 4 times with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Deduct 172 from 212 and we're left with 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 43

Let's proceed to step 4:
43 goes into 405 9 times with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 149.0
If we take 387 away from 405, we end up with 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 43

Moving on to step 5:
43 goes into 184 4 times with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 1494.0
If we take 172 away from 184, we end up with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 43

Let's proceed to step 6:
When dividing 129 by 43, we get 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 14943.0
Subtracting 129 from 129 leaves us with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 43

Going ahead to step 7:
43 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 149430.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 43

Moving on to step 8:
If we divide 90 by 43, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 1494302.0
If we take 86 away from 90, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
When dividing 40 by 43, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 1494302.0
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
43 goes into 400 9 times with a remainder of 13.
The next digit of our result is 9. 
Result so far: 1494302.09
The remainder is 13 after subtracting 387 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 11:
The number 43 fits into 130 3 times, leaving a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 1494302.093
The remainder is 1 after subtracting 129 from 130.
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 12:
The number 43 fits into 10 0 times, leaving a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 1494302.093
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 13:
When dividing 100 by 43, we get 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 1494302.09302
Subtracting 86 from 100 leaves us 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.

Advancing to step 14:
43 goes into 140 3 times with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 1494302.093023
If we take 129 away from 140, we end up 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.

Step 15:
The number 43 fits into 110 2 times, leaving a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 1494302.0930232
Subtract 86 from 110 to 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 16:
The number 43 fits into 240 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 1494302.09302325
Subtracting 215 from 240 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

In conclusion, the division gives 1494302.09302325 with a balance of 2.5e-08.
