42041561 ÷ 286 
We want to divide 42041561 by 286.

Moving on to step 1:
4 divided by 286 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 286

Going ahead to step 2:
The number 286 fits into 42 0 times, leaving a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 42, we end up with 42.
Include the next digit (0) from the dividend after 42, then repeat: 420 / 286

Let's proceed to step 3:
The number 286 fits into 420 1 times, leaving a remainder of 134.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 286 away from 420, we end up with 134.
Append the next digit (4) from the dividend to 134 and continue with: 1344 / 286

Step 4:
When dividing 1344 by 286, we get 4 with a remainder of 200.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtracting 1144 from 1344 leaves us with 200.
Grab the next digit (1) from the dividend, add it to 200, then carry on: 2001 / 286

Moving on to step 5:
If we divide 2001 by 286, we get 6 and a remainder of 285.
The number 6 becomes the next digit in our result. 
Result so far: 146.0
Subtract 1716 from 2001 to get 285.
Bring next digit (5) of the dividend behind the 285 and repeat the process: 2855 / 286

On to step 6:
286 goes into 2855 9 times with a remainder of 281.
The next digit of our result is 9. 
Result so far: 1469.0
Subtracting 2574 from 2855 leaves us with 281.
Fetch the next digit (6) from the dividend, attach it to 281 and continue: 2816 / 286

Step 7:
The number 286 fits into 2816 9 times, leaving a remainder of 242.
Put 9 as the next digit of the answer. 
Result so far: 14699.0
If we subtract 2574 from 2816, we get 242.
Append the next digit (1) from the dividend to 242 and continue with: 2421 / 286

Going ahead to step 8:
286 goes into 2421 8 times with a remainder of 133.
Write down 8 as next digit of the result. 
Result so far: 146998.0
Subtract 2288 from 2421 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Step 9:
286 can be fit into 1330 4 times, resulting in a remainder of 186.
The number 4 becomes the next digit in our result. 
Result so far: 146998.4
If we take 1144 away from 1330, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Moving on to step 10:
The number 286 fits into 1860 6 times, leaving a remainder of 144.
Use 6 as the next digit of our solution. 
Result so far: 146998.46
The remainder is 144 after subtracting 1716 from 1860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 11:
286 can be fit into 1440 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 146998.465
If we subtract 1430 from 1440, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
286 can be fit into 100 0 times, resulting in a remainder of 100.
The next digit of our result is 0. 
Result so far: 146998.465
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 13:
When dividing 1000 by 286, we get 3 with a remainder of 142.
Use 3 as the next digit of our solution. 
Result so far: 146998.46503
Deduct 858 from 1000 and we're left with 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Let's proceed to step 14:
If we divide 1420 by 286, we get 4 and a remainder of 276.
Write down 4 as next digit of the result. 
Result so far: 146998.465034
Subtracting 1144 from 1420 leaves us with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 15:
286 goes into 2760 9 times with a remainder of 186.
Record the quotient 9 as the next digit in the result. 
Result so far: 146998.4650349
If we take 2574 away from 2760, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 16:
286 can be fit into 1860 6 times, resulting in a remainder of 144.
Record the quotient 6 as the next digit in the result. 
Result so far: 146998.46503496
Subtracting 1716 from 1860 leaves us with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Our division results in 146998.46503496 with a remaining 1.44e-07.
