286397 ÷ 68 
Let's see how many times 68 fits into 286397.

On to step 1:
The number 68 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 68

On to step 2:
If we divide 28 by 68, we get 0 and a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 68

Going ahead to step 3:
When dividing 286 by 68, we get 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 14 after subtracting 272 from 286.
Append the next digit (3) from the dividend to 14 and continue with: 143 / 68

Let's proceed to step 4:
If we divide 143 by 68, we get 2 and a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtract 136 from 143 to get 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 68

Moving on to step 5:
If we divide 79 by 68, we get 1 and a remainder of 11.
Put 1 as the next digit of the answer. 
Result so far: 421.0
Subtract 68 from 79 to get 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 68

Step 6:
When dividing 117 by 68, we get 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 4211.0
Deduct 68 from 117 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
68 can be fit into 490 7 times, resulting in a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 4211.7
The remainder is 14 after subtracting 476 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
The number 68 fits into 140 2 times, leaving a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 4211.72
If we take 136 away from 140, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
68 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 4211.72
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
68 goes into 400 5 times with a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 4211.7205
If we take 340 away from 400, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 11:
68 goes into 600 8 times with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 4211.72058
If we take 544 away from 600, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 12:
68 goes into 560 8 times with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 4211.720588
If we subtract 544 from 560, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 4211.720588, with a leftover of 1.6e-06.
