We look at the division of 3955957 by 43 
Our goal is to divide 3955957 by 43.

Moving on to step 1:
If we divide 3 by 43, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 43

Moving on to step 2:
The number 43 fits into 39 0 times, leaving a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 43

On to step 3:
The number 43 fits into 395 9 times, leaving a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 387 away from 395, we end up with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 43

On to step 4:
43 goes into 85 1 times with a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 91.0
Subtract 43 from 85 to get 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 43

Let's proceed to step 5:
43 goes into 429 9 times with a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 919.0
Subtracting 387 from 429 leaves us with 42.
Fetch the next digit (5) from the dividend, attach it to 42 and continue: 425 / 43

Step 6:
The number 43 fits into 425 9 times, leaving a remainder of 38.
The next digit of our result is 9. 
Result so far: 9199.0
The remainder is 38 after subtracting 387 from 425.
Include the next digit (7) from the dividend after 38, then repeat: 387 / 43

Going ahead to step 7:
If we divide 387 by 43, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 91999.0
Subtract 387 from 387 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
0 divided by 43 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 91999.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
If we divide 0 by 43, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 91999.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 91999.0 and a remainder of 0.0.
