91958 ÷ 43 
Let's see how many times 43 fits into 91958.

Advancing to step 1:
43 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 43

Moving on to step 2:
The number 43 fits into 91 2 times, leaving a remainder of 5.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 86 from 91 to get 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 43

Advancing to step 3:
The number 43 fits into 59 1 times, leaving a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 43 from 59 to get 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 43

Moving on to step 4:
If we divide 165 by 43, we get 3 and a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 213.0
Subtract 129 from 165 to get 36.
Bring next digit (8) of the dividend behind the 36 and repeat the process: 368 / 43

Let's proceed to step 5:
43 can be fit into 368 8 times, resulting in a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 2138.0
If we subtract 344 from 368, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 6:
43 goes into 240 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 2138.5
The remainder is 25 after subtracting 215 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 7:
When dividing 250 by 43, we get 5 with a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 2138.55
Deduct 215 from 250 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 2138.55 with a remainder of 0.035.
