735353 ÷ 43 
The aim is to understand the frequency of 43 in 735353.

Let's proceed to step 1:
When dividing 7 by 43, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 43

On to step 2:
43 can be fit into 73 1 times, resulting in a remainder of 30.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 43 from 73 and we're left with 30.
Include the next digit (5) from the dividend after 30, then repeat: 305 / 43

Let's proceed to step 3:
The number 43 fits into 305 7 times, leaving a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 301 from 305 to get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 43

Moving on to step 4:
If we divide 43 by 43, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 171.0
If we subtract 43 from 43, we get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 43

On to step 5:
43 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 1710.0
If we take 0 away from 5, we end up with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 43

Step 6:
43 goes into 53 1 times with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 17101.0
If we take 43 away from 53, we end up 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.

Going ahead to step 7:
The number 43 fits into 100 2 times, leaving a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 17101.2
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.

Advancing to step 8:
When dividing 140 by 43, we get 3 with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 17101.23
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.

Advancing to step 9:
110 divided by 43 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 17101.232
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 10:
When dividing 240 by 43, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 17101.2325
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.

Step 11:
The number 43 fits into 250 5 times, leaving a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 17101.23255
Deduct 215 from 250 and we're left with 35.
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 outcome is 17101.23255, with a leftover of 3.5e-05.
