We look at the division of 305396 by 43 
Let's see how many times 43 fits into 305396.

Advancing to step 1:
When dividing 3 by 43, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 43

Moving on to step 2:
When dividing 30 by 43, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Append the next digit (5) from the dividend to 30 and continue with: 305 / 43

Moving on to step 3:
43 can be fit into 305 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 301 from 305, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 43

Step 4:
43 can be fit into 43 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 71.0
The remainder is 0 after subtracting 43 from 43.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 43

Let's proceed to step 5:
9 divided by 43 is 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 710.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (6) from the dividend, attach it to 9 and continue: 96 / 43

Advancing to step 6:
The number 43 fits into 96 2 times, leaving a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 7102.0
Subtracting 86 from 96 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
100 divided by 43 is 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 7102.2
If we subtract 86 from 100, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
If we divide 140 by 43, we get 3 and a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 7102.23
Deduct 129 from 140 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 9:
43 goes into 110 2 times with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 7102.232
If we take 86 away from 110, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
When dividing 240 by 43, we get 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 7102.2325
Deduct 215 from 240 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 11:
The number 43 fits into 250 5 times, leaving a remainder of 35.
The next digit of our result is 5. 
Result so far: 7102.23255
If we take 215 away from 250, we end up 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.

After the division, we end up with 7102.23255 and a remainder of 3.5e-05.
