We're dividing 389743 by 9 
Our goal is to divide 389743 by 9.

Going ahead to step 1:
If we divide 3 by 9, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 9

Let's proceed to step 2:
If we divide 38 by 9, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 36 away from 38, we end up with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 9

Step 3:
The number 9 fits into 29 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 43.0
The remainder is 2 after subtracting 27 from 29.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 9

Moving on to step 4:
The number 9 fits into 27 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 433.0
If we subtract 27 from 27, we get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 9

Let's proceed to step 5:
When dividing 4 by 9, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 4330.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 9

Let's proceed to step 6:
When dividing 43 by 9, we get 4 with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 43304.0
Subtract 36 from 43 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.

Step 7:
9 goes into 70 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 43304.7
Deduct 63 from 70 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 8:
When dividing 70 by 9, we get 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 43304.77
Deduct 63 from 70 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The quotient of the division is 43304.77, and the remainder is 0.007.
