Let's divide 154319 by 43
The aim is to understand the frequency of 43 in 154319.

Step 1:
43 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 43

On to step 2:
If we divide 15 by 43, we get 0 and a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 43

Going ahead to step 3:
43 goes into 154 3 times with a remainder of 25.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 129 from 154 to get 25.
Append the next digit (3) from the dividend to 25 and continue with: 253 / 43

Moving on to step 4:
If we divide 253 by 43, we get 5 and a remainder of 38.
Write down 5 as next digit of the result. 
Result so far: 35.0
Deduct 215 from 253 and we're left with 38.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 43

On to step 5:
The number 43 fits into 381 8 times, leaving a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 358.0
The remainder is 37 after subtracting 344 from 381.
Take the next digit (9) from the dividend and append it to 37, then repeat: 379 / 43

On to step 6:
If we divide 379 by 43, we get 8 and a remainder of 35.
Record the quotient 8 as the next digit in the result. 
Result so far: 3588.0
If we subtract 344 from 379, we 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.

Let's proceed to step 7:
350 divided by 43 is 8 with a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 3588.8
Subtract 344 from 350 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
43 can be fit into 60 1 times, resulting in a remainder of 17.
The next digit of our result is 1. 
Result so far: 3588.81
If we take 43 away from 60, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
43 goes into 170 3 times with a remainder of 41.
The next digit of our result is 3. 
Result so far: 3588.813
If we take 129 away from 170, 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.

Advancing to step 10:
43 goes into 410 9 times with a remainder of 23.
Put 9 as the next digit of the answer. 
Result so far: 3588.8139
Subtract 387 from 410 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 11:
230 divided by 43 is 5 with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 3588.81395
Subtracting 215 from 230 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
When dividing 150 by 43, we get 3 with a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 3588.813953
Subtracting 129 from 150 leaves us 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.

Moving on to step 13:
The number 43 fits into 210 4 times, leaving a remainder of 38.
Put 4 as the next digit of the answer. 
Result so far: 3588.8139534
Subtract 172 from 210 to 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.

Step 14:
380 divided by 43 is 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 3588.81395348
Deduct 344 from 380 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 3588.81395348, with a leftover of 3.6e-08.
