235681 ÷ 43 
The aim is to understand the frequency of 43 in 235681.

Moving on to step 1:
The number 43 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 43

Moving on to step 2:
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: 0.0
Subtract 0 from 23 to get 23.
Fetch the next digit (5) from the dividend, attach it to 23 and continue: 235 / 43

On to step 3:
If we divide 235 by 43, we get 5 and a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 215 from 235 leaves us with 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 43

Moving on to step 4:
When dividing 206 by 43, we get 4 with a remainder of 34.
Record the quotient 4 as the next digit in the result. 
Result so far: 54.0
Deduct 172 from 206 and we're left with 34.
Take the next digit (8) from the dividend and append it to 34, then repeat: 348 / 43

On to step 5:
If we divide 348 by 43, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 548.0
If we take 344 away from 348, we end up with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 43

Advancing to step 6:
The number 43 fits into 41 0 times, leaving a remainder of 41.
Use 0 as the next digit of our solution. 
Result so far: 5480.0
If we take 0 away from 41, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 7:
The number 43 fits into 410 9 times, leaving a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 5480.9
The remainder is 23 after subtracting 387 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 8:
230 divided by 43 is 5 with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 5480.95
If we subtract 215 from 230, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 9:
43 goes into 150 3 times with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 5480.953
Deduct 129 from 150 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 10:
If we divide 210 by 43, we get 4 and a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 5480.9534
If we subtract 172 from 210, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
If we divide 380 by 43, we get 8 and a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 5480.95348
The remainder is 36 after subtracting 344 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 12:
360 divided by 43 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 5480.953488
The remainder is 16 after subtracting 344 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 5480.953488 with a remaining 1.6e-06.
