We look at the division of 31430 by 43 
Our goal is to divide 31430 by 43.

On to step 1:
3 divided by 43 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 43

On to step 2:
The number 43 fits into 31 0 times, leaving a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 31 leaves us with 31.
Bring next digit (4) of the dividend behind the 31 and repeat the process: 314 / 43

Advancing to step 3:
The number 43 fits into 314 7 times, leaving a remainder of 13.
The next digit of our result is 7. 
Result so far: 7.0
Subtract 301 from 314 to get 13.
Append the next digit (3) from the dividend to 13 and continue with: 133 / 43

On to step 4:
When dividing 133 by 43, we get 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 73.0
If we subtract 129 from 133, we get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 43

Let's proceed to step 5:
The number 43 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 730.0
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 6:
43 goes into 400 9 times with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 730.9
If we take 387 away from 400, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
If we divide 130 by 43, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 730.93
Subtract 129 from 130 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 8:
10 divided by 43 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 730.93
If we take 0 away from 10, we end up 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.

Let's proceed to step 9:
The number 43 fits into 100 2 times, leaving a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 730.9302
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.

Going ahead to step 10:
When dividing 140 by 43, we get 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 730.93023
Subtracting 129 from 140 leaves us 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.

Moving on to step 11:
If we divide 110 by 43, we get 2 and a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 730.930232
If we subtract 86 from 110, 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 12:
When dividing 240 by 43, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 730.9302325
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.

Let's proceed to step 13:
The number 43 fits into 250 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 730.93023255
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 730.93023255 and a remainder of 3.5e-08.
