We look at the division of 54000158 by 43 
Let's see how many times 43 fits into 54000158.

Step 1:
The number 43 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 43

Let's proceed to step 2:
If we divide 54 by 43, we get 1 and a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
If we take 43 away from 54, we end up with 11.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 43

Let's proceed to step 3:
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: 12.0
Subtract 86 from 110 to get 24.
Append the next digit (0) from the dividend to 24 and continue with: 240 / 43

Step 4:
43 can be fit into 240 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
Subtract 215 from 240 to get 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 43

Moving on to step 5:
43 goes into 250 5 times with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 1255.0
Subtracting 215 from 250 leaves us with 35.
Include the next digit (1) from the dividend after 35, then repeat: 351 / 43

Going ahead to step 6:
The number 43 fits into 351 8 times, leaving a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 12558.0
Deduct 344 from 351 and we're left with 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 43

Moving on to step 7:
43 can be fit into 75 1 times, resulting in a remainder of 32.
The next digit of our result is 1. 
Result so far: 125581.0
The remainder is 32 after subtracting 43 from 75.
Bring next digit (8) of the dividend behind the 32 and repeat the process: 328 / 43

Step 8:
If we divide 328 by 43, we get 7 and a remainder of 27.
Write down 7 as next digit of the result. 
Result so far: 1255817.0
If we take 301 away from 328, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 9:
If we divide 270 by 43, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 1255817.6
If we take 258 away from 270, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
If we divide 120 by 43, we get 2 and a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 1255817.62
Subtracting 86 from 120 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 11:
The number 43 fits into 340 7 times, leaving a remainder of 39.
The next digit of our result is 7. 
Result so far: 1255817.627
If we take 301 away from 340, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 12:
390 divided by 43 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 1255817.6279
Subtract 387 from 390 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
The number 43 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 1255817.6279
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 14:
The number 43 fits into 300 6 times, leaving a remainder of 42.
Put 6 as the next digit of the answer. 
Result so far: 1255817.627906
Subtracting 258 from 300 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 15:
When dividing 420 by 43, we get 9 with a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 1255817.6279069
The remainder is 33 after subtracting 387 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 16:
330 divided by 43 is 7 with a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 1255817.62790697
The remainder is 29 after subtracting 301 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

The final result is 1255817.62790697 with a remainder of 2.9e-08.
