We look at the division of 83958 by 43 
We want to divide 83958 by 43.

Advancing to step 1:
The number 43 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 43

On to step 2:
43 goes into 83 1 times with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 43 away from 83, we end up with 40.
Take the next digit (9) from the dividend and append it to 40, then repeat: 409 / 43

Advancing to step 3:
409 divided by 43 is 9 with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we take 387 away from 409, we end up with 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 43

On to step 4:
The number 43 fits into 225 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 195.0
Subtracting 215 from 225 leaves us with 10.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 43

Let's proceed to step 5:
The number 43 fits into 108 2 times, leaving a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 1952.0
Deduct 86 from 108 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 6:
43 goes into 220 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 1952.5
Subtract 215 from 220 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
43 can be fit into 50 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1952.51
Subtract 43 from 50 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
When dividing 70 by 43, we get 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 1952.511
Deduct 43 from 70 and we're left 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.

The quotient of the division is 1952.511, and the remainder is 0.0027.
