401934 ÷ 43 
The aim is to understand the frequency of 43 in 401934.

Advancing to step 1:
43 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 43

Going ahead to step 2:
The number 43 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Include the next digit (1) from the dividend after 40, then repeat: 401 / 43

Moving on to step 3:
43 can be fit into 401 9 times, resulting in a remainder of 14.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 387 from 401 and we're left with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 43

Step 4:
When dividing 149 by 43, we get 3 with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 93.0
If we subtract 129 from 149, we get 20.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 43

Moving on to step 5:
When dividing 203 by 43, we get 4 with a remainder of 31.
Put 4 as the next digit of the answer. 
Result so far: 934.0
If we take 172 away from 203, we end up with 31.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 43

Let's proceed to step 6:
314 divided by 43 is 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 9347.0
If we take 301 away from 314, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
The number 43 fits into 130 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 9347.3
If we subtract 129 from 130, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
When dividing 10 by 43, we get 0 with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 9347.3
Subtract 0 from 10 to get 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 9:
43 can be fit into 100 2 times, resulting in a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 9347.302
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.

Going ahead to step 10:
The number 43 fits into 140 3 times, leaving a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 9347.3023
Subtract 129 from 140 to get 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 11:
If we divide 110 by 43, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 9347.30232
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.

On to step 12:
240 divided by 43 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 9347.302325
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.

Let's proceed to step 13:
43 can be fit into 250 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 9347.3023255
Subtract 215 from 250 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 9347.3023255 with a remaining 3.5e-07.
