40431470 ÷ 389 
We want to divide 40431470 by 389.

Advancing to step 1:
389 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 389

On to step 2:
40 divided by 389 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Bring next digit (4) of the dividend behind the 40 and repeat the process: 404 / 389

On to step 3:
404 divided by 389 is 1 with a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 389 from 404 to get 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 389

Advancing to step 4:
153 divided by 389 is 0 with a remainder of 153.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 153 after subtracting 0 from 153.
Include the next digit (1) from the dividend after 153, then repeat: 1531 / 389

On to step 5:
389 can be fit into 1531 3 times, resulting in a remainder of 364.
The next digit of our result is 3. 
Result so far: 103.0
Subtracting 1167 from 1531 leaves us with 364.
Include the next digit (4) from the dividend after 364, then repeat: 3644 / 389

Moving on to step 6:
389 goes into 3644 9 times with a remainder of 143.
Record the quotient 9 as the next digit in the result. 
Result so far: 1039.0
The remainder is 143 after subtracting 3501 from 3644.
Fetch the next digit (7) from the dividend, attach it to 143 and continue: 1437 / 389

Moving on to step 7:
When dividing 1437 by 389, we get 3 with a remainder of 270.
Record the quotient 3 as the next digit in the result. 
Result so far: 10393.0
The remainder is 270 after subtracting 1167 from 1437.
Include the next digit (0) from the dividend after 270, then repeat: 2700 / 389

On to step 8:
When dividing 2700 by 389, we get 6 with a remainder of 366.
The next digit of our result is 6. 
Result so far: 103936.0
Subtracting 2334 from 2700 leaves us with 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

On to step 9:
389 can be fit into 3660 9 times, resulting in a remainder of 159.
The number 9 becomes the next digit in our result. 
Result so far: 103936.9
The remainder is 159 after subtracting 3501 from 3660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Moving on to step 10:
1590 divided by 389 is 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 103936.94
If we take 1556 away from 1590, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
389 goes into 340 0 times with a remainder of 340.
The next digit of our result is 0. 
Result so far: 103936.94
Subtract 0 from 340 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Step 12:
If we divide 3400 by 389, we get 8 and a remainder of 288.
Write down 8 as next digit of the result. 
Result so far: 103936.9408
The remainder is 288 after subtracting 3112 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 13:
When dividing 2880 by 389, we get 7 with a remainder of 157.
The number 7 becomes the next digit in our result. 
Result so far: 103936.94087
Deduct 2723 from 2880 and we're left with 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

Going ahead to step 14:
The number 389 fits into 1570 4 times, leaving a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 103936.940874
If we take 1556 away from 1570, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 15:
When dividing 140 by 389, we get 0 with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 103936.940874
Subtract 0 from 140 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 16:
If we divide 1400 by 389, we get 3 and a remainder of 233.
Use 3 as the next digit of our solution. 
Result so far: 103936.94087403
Subtracting 1167 from 1400 leaves us with 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

The final outcome is 103936.94087403, with a leftover of 2.33e-07.
