We're dividing 43689 by 46 
The aim is to understand the frequency of 46 in 43689.

Step 1:
The number 46 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 46

Moving on to step 2:
46 goes into 43 0 times with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 43 and we're left with 43.
Append the next digit (6) from the dividend to 43 and continue with: 436 / 46

Going ahead to step 3:
The number 46 fits into 436 9 times, leaving a remainder of 22.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 414 from 436, we get 22.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 46

Let's proceed to step 4:
If we divide 228 by 46, we get 4 and a remainder of 44.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
Deduct 184 from 228 and we're left with 44.
Fetch the next digit (9) from the dividend, attach it to 44 and continue: 449 / 46

Moving on to step 5:
The number 46 fits into 449 9 times, leaving a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 949.0
Subtract 414 from 449 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.

Step 6:
The number 46 fits into 350 7 times, leaving a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 949.7
Subtracting 322 from 350 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 7:
46 can be fit into 280 6 times, resulting in a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 949.76
If we take 276 away from 280, 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 8:
When dividing 40 by 46, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 949.76
If we subtract 0 from 40, we get 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 9:
The number 46 fits into 400 8 times, leaving a remainder of 32.
The next digit of our result is 8. 
Result so far: 949.7608
If we take 368 away from 400, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
When dividing 320 by 46, we get 6 with a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 949.76086
If we subtract 276 from 320, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 11:
When dividing 440 by 46, we get 9 with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 949.760869
The remainder is 26 after subtracting 414 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
46 can be fit into 260 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 949.7608695
The remainder is 30 after subtracting 230 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
300 divided by 46 is 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 949.76086956
The remainder is 24 after subtracting 276 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 949.76086956 and a remainder of 2.4e-08.
