12060291 ÷ 286 
Let's see how many times 286 fits into 12060291.

Advancing to step 1:
The number 286 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 286

Advancing to step 2:
If we divide 12 by 286, we get 0 and a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 286

Let's proceed to step 3:
286 goes into 120 0 times with a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 120 leaves us with 120.
Include the next digit (6) from the dividend after 120, then repeat: 1206 / 286

Step 4:
The number 286 fits into 1206 4 times, leaving a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 1144 from 1206 and we're left with 62.
Fetch the next digit (0) from the dividend, attach it to 62 and continue: 620 / 286

Moving on to step 5:
When dividing 620 by 286, we get 2 with a remainder of 48.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Deduct 572 from 620 and we're left with 48.
Append the next digit (2) from the dividend to 48 and continue with: 482 / 286

Advancing to step 6:
286 goes into 482 1 times with a remainder of 196.
Use 1 as the next digit of our solution. 
Result so far: 421.0
Subtract 286 from 482 to get 196.
Include the next digit (9) from the dividend after 196, then repeat: 1969 / 286

Let's proceed to step 7:
286 can be fit into 1969 6 times, resulting in a remainder of 253.
Write down 6 as next digit of the result. 
Result so far: 4216.0
If we take 1716 away from 1969, we end up with 253.
Fetch the next digit (1) from the dividend, attach it to 253 and continue: 2531 / 286

Step 8:
If we divide 2531 by 286, we get 8 and a remainder of 243.
Use 8 as the next digit of our solution. 
Result so far: 42168.0
If we subtract 2288 from 2531, we get 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Going ahead to step 9:
286 can be fit into 2430 8 times, resulting in a remainder of 142.
The number 8 becomes the next digit in our result. 
Result so far: 42168.8
If we take 2288 away from 2430, we end up 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.

Moving on to step 10:
The number 286 fits into 1420 4 times, leaving a remainder of 276.
The number 4 becomes the next digit in our result. 
Result so far: 42168.84
The remainder is 276 after subtracting 1144 from 1420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Advancing to step 11:
286 goes into 2760 9 times with a remainder of 186.
Use 9 as the next digit of our solution. 
Result so far: 42168.849
The remainder is 186 after subtracting 2574 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Going ahead to step 12:
When dividing 1860 by 286, we get 6 with a remainder of 144.
The next digit of our result is 6. 
Result so far: 42168.8496
Subtract 1716 from 1860 to get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Advancing to step 13:
When dividing 1440 by 286, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 42168.84965
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.

Moving on to step 14:
286 can be fit into 100 0 times, resulting in a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 42168.84965
Subtracting 0 from 100 leaves us 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.

On to step 15:
286 goes into 1000 3 times with a remainder of 142.
Record the quotient 3 as the next digit in the result. 
Result so far: 42168.8496503
If we subtract 858 from 1000, we get 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Step 16:
286 can be fit into 1420 4 times, resulting in a remainder of 276.
The next digit of our result is 4. 
Result so far: 42168.84965034
Deduct 1144 from 1420 and we're left 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.

The final outcome is 42168.84965034, with a leftover of 2.76e-07.
