169988 ÷ 43 
The aim is to understand the frequency of 43 in 169988.

Let's proceed to step 1:
43 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 43

On to step 2:
The number 43 fits into 16 0 times, leaving a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 43

Advancing to step 3:
When dividing 169 by 43, we get 3 with a remainder of 40.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 129 away from 169, we end up with 40.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 43

Step 4:
If we divide 409 by 43, we get 9 and a remainder of 22.
The next digit of our result is 9. 
Result so far: 39.0
If we subtract 387 from 409, we get 22.
Bring next digit (8) of the dividend behind the 22 and repeat the process: 228 / 43

Step 5:
43 can be fit into 228 5 times, resulting in a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 395.0
Subtract 215 from 228 to get 13.
Append the next digit (8) from the dividend to 13 and continue with: 138 / 43

Going ahead to step 6:
When dividing 138 by 43, we get 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 3953.0
If we subtract 129 from 138, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
When dividing 90 by 43, we get 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 3953.2
Deduct 86 from 90 and we're left 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.

On to step 8:
When dividing 40 by 43, we get 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 3953.2
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
If we divide 400 by 43, we get 9 and a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 3953.209
The remainder is 13 after subtracting 387 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 10:
130 divided by 43 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 3953.2093
The remainder is 1 after subtracting 129 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 11:
If we divide 10 by 43, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 3953.2093
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.

Moving on to step 12:
43 goes into 100 2 times with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 3953.209302
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 13:
43 can be fit into 140 3 times, resulting in a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 3953.2093023
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.

Step 14:
When dividing 110 by 43, we get 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 3953.20930232
Subtracting 86 from 110 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 3953.20930232 with a balance of 2.4e-08.
