We look at the division of 90942458 by 43 
Let's see how many times 43 fits into 90942458.

Moving on to step 1:
When dividing 9 by 43, we get 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 43

Let's proceed to step 2:
If we divide 90 by 43, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 86 from 90 to get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 43

On to step 3:
When dividing 49 by 43, we get 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 21.0
Subtract 43 from 49 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 43

On to step 4:
The number 43 fits into 64 1 times, leaving a remainder of 21.
The next digit of our result is 1. 
Result so far: 211.0
Subtract 43 from 64 to get 21.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 43

Moving on to step 5:
43 goes into 212 4 times with a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 2114.0
The remainder is 40 after subtracting 172 from 212.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 43

Advancing to step 6:
404 divided by 43 is 9 with a remainder of 17.
The number 9 becomes the next digit in our result. 
Result so far: 21149.0
The remainder is 17 after subtracting 387 from 404.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 43

Let's proceed to step 7:
When dividing 175 by 43, we get 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 211494.0
Deduct 172 from 175 and we're left with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 43

Step 8:
If we divide 38 by 43, we get 0 and a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 2114940.0
If we subtract 0 from 38, we 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.

On to step 9:
When dividing 380 by 43, we get 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 2114940.8
If we take 344 away from 380, we end up 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.

Step 10:
43 can be fit into 360 8 times, resulting in a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 2114940.88
Deduct 344 from 360 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 2114940.88 with a remainder of 0.016.
