We look at the division of 991356 by 43 
The aim is to understand the frequency of 43 in 991356.

Let's proceed to step 1:
The number 43 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 43

Moving on to step 2:
When dividing 99 by 43, we get 2 with a remainder of 13.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 86 from 99 to get 13.
Bring next digit (1) of the dividend behind the 13 and repeat the process: 131 / 43

Advancing to step 3:
The number 43 fits into 131 3 times, leaving a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we subtract 129 from 131, we get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 43

Moving on to step 4:
43 can be fit into 23 0 times, resulting in a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 230.0
Subtracting 0 from 23 leaves us with 23.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 43

Step 5:
When dividing 235 by 43, we get 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 2305.0
Deduct 215 from 235 and we're left with 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 43

Let's proceed to step 6:
206 divided by 43 is 4 with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 23054.0
Subtract 172 from 206 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
If we divide 340 by 43, we get 7 and a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 23054.7
Subtract 301 from 340 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 8:
390 divided by 43 is 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 23054.79
If we take 387 away from 390, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 9:
The number 43 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 23054.79
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
The number 43 fits into 300 6 times, leaving a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 23054.7906
Subtracting 258 from 300 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
420 divided by 43 is 9 with a remainder of 33.
Put 9 as the next digit of the answer. 
Result so far: 23054.79069
The remainder is 33 after subtracting 387 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 12:
The number 43 fits into 330 7 times, leaving a remainder of 29.
The next digit of our result is 7. 
Result so far: 23054.790697
The remainder is 29 after subtracting 301 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 13:
43 goes into 290 6 times with a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 23054.7906976
If we subtract 258 from 290, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 14:
The number 43 fits into 320 7 times, leaving a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 23054.79069767
Deduct 301 from 320 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 23054.79069767 and a remainder of 1.9e-08.
