40103343 ÷ 285 
We want to divide 40103343 by 285.

On to step 1:
285 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 285

On to step 2:
If we divide 40 by 285, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Include the next digit (1) from the dividend after 40, then repeat: 401 / 285

Step 3:
401 divided by 285 is 1 with a remainder of 116.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 116 after subtracting 285 from 401.
Include the next digit (0) from the dividend after 116, then repeat: 1160 / 285

Step 4:
When dividing 1160 by 285, we get 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
Deduct 1140 from 1160 and we're left with 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 285

Let's proceed to step 5:
When dividing 203 by 285, we get 0 with a remainder of 203.
Write down 0 as next digit of the result. 
Result so far: 140.0
Subtract 0 from 203 to get 203.
Bring next digit (3) of the dividend behind the 203 and repeat the process: 2033 / 285

Going ahead to step 6:
2033 divided by 285 is 7 with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 1407.0
If we take 1995 away from 2033, we end up with 38.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 285

Step 7:
384 divided by 285 is 1 with a remainder of 99.
Put 1 as the next digit of the answer. 
Result so far: 14071.0
The remainder is 99 after subtracting 285 from 384.
Append the next digit (3) from the dividend to 99 and continue with: 993 / 285

Let's proceed to step 8:
285 goes into 993 3 times with a remainder of 138.
Record the quotient 3 as the next digit in the result. 
Result so far: 140713.0
Subtracting 855 from 993 leaves us with 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Going ahead to step 9:
When dividing 1380 by 285, we get 4 with a remainder of 240.
The next digit of our result is 4. 
Result so far: 140713.4
The remainder is 240 after subtracting 1140 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Step 10:
2400 divided by 285 is 8 with a remainder of 120.
Record the quotient 8 as the next digit in the result. 
Result so far: 140713.48
If we take 2280 away from 2400, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 11:
The number 285 fits into 1200 4 times, leaving a remainder of 60.
The number 4 becomes the next digit in our result. 
Result so far: 140713.484
Subtract 1140 from 1200 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 12:
When dividing 600 by 285, we get 2 with a remainder of 30.
Use 2 as the next digit of our solution. 
Result so far: 140713.4842
If we take 570 away from 600, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 13:
The number 285 fits into 300 1 times, leaving a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 140713.48421
If we subtract 285 from 300, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 14:
285 can be fit into 150 0 times, resulting in a remainder of 150.
Use 0 as the next digit of our solution. 
Result so far: 140713.48421
If we subtract 0 from 150, we get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 15:
285 can be fit into 1500 5 times, resulting in a remainder of 75.
The next digit of our result is 5. 
Result so far: 140713.4842105
Deduct 1425 from 1500 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 16:
285 can be fit into 750 2 times, resulting in a remainder of 180.
The number 2 becomes the next digit in our result. 
Result so far: 140713.48421052
Subtract 570 from 750 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Our division results in 140713.48421052 with a remaining 1.8e-07.
