402 divided by 43 
We want to divide 402 by 43.

Let's proceed to step 1:
43 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 43

Going ahead to step 2:
43 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Bring next digit (2) of the dividend behind the 40 and repeat the process: 402 / 43

Moving on to step 3:
43 goes into 402 9 times with a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 387 away from 402, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 4:
150 divided by 43 is 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 9.3
The remainder is 21 after subtracting 129 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 5:
The number 43 fits into 210 4 times, leaving a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 9.34
If we subtract 172 from 210, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 6:
43 can be fit into 380 8 times, resulting in a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 9.348
Deduct 344 from 380 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 7:
When dividing 360 by 43, we get 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 9.3488
The remainder is 16 after subtracting 344 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 9.3488 with a remaining 0.00016.
