3943779 divided by 432 
Our goal is to divide 3943779 by 432.

Step 1:
432 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 432

Step 2:
The number 432 fits into 39 0 times, leaving a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 39 to get 39.
Fetch the next digit (4) from the dividend, attach it to 39 and continue: 394 / 432

Going ahead to step 3:
If we divide 394 by 432, we get 0 and a remainder of 394.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 394 leaves us with 394.
Fetch the next digit (3) from the dividend, attach it to 394 and continue: 3943 / 432

Let's proceed to step 4:
The number 432 fits into 3943 9 times, leaving a remainder of 55.
The next digit of our result is 9. 
Result so far: 9.0
Subtract 3888 from 3943 to get 55.
Grab the next digit (7) from the dividend, add it to 55, then carry on: 557 / 432

Moving on to step 5:
432 can be fit into 557 1 times, resulting in a remainder of 125.
Record the quotient 1 as the next digit in the result. 
Result so far: 91.0
The remainder is 125 after subtracting 432 from 557.
Take the next digit (7) from the dividend and append it to 125, then repeat: 1257 / 432

Step 6:
The number 432 fits into 1257 2 times, leaving a remainder of 393.
The next digit of our result is 2. 
Result so far: 912.0
If we take 864 away from 1257, we end up with 393.
Append the next digit (9) from the dividend to 393 and continue with: 3939 / 432

On to step 7:
432 goes into 3939 9 times with a remainder of 51.
Use 9 as the next digit of our solution. 
Result so far: 9129.0
Deduct 3888 from 3939 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 8:
432 can be fit into 510 1 times, resulting in a remainder of 78.
The number 1 becomes the next digit in our result. 
Result so far: 9129.1
Deduct 432 from 510 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 9:
When dividing 780 by 432, we get 1 with a remainder of 348.
Write down 1 as next digit of the result. 
Result so far: 9129.11
If we subtract 432 from 780, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

The quotient of the division is 9129.11, and the remainder is 0.348.
