67860344 ÷ 289 
We want to divide 67860344 by 289.

Step 1:
289 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 289

On to step 2:
The number 289 fits into 67 0 times, leaving a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Take the next digit (8) from the dividend and append it to 67, then repeat: 678 / 289

Going ahead to step 3:
678 divided by 289 is 2 with a remainder of 100.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 100 after subtracting 578 from 678.
Fetch the next digit (6) from the dividend, attach it to 100 and continue: 1006 / 289

Moving on to step 4:
1006 divided by 289 is 3 with a remainder of 139.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Deduct 867 from 1006 and we're left with 139.
Fetch the next digit (0) from the dividend, attach it to 139 and continue: 1390 / 289

Step 5:
1390 divided by 289 is 4 with a remainder of 234.
Write down 4 as next digit of the result. 
Result so far: 234.0
If we subtract 1156 from 1390, we get 234.
Include the next digit (3) from the dividend after 234, then repeat: 2343 / 289

Step 6:
If we divide 2343 by 289, we get 8 and a remainder of 31.
Put 8 as the next digit of the answer. 
Result so far: 2348.0
If we take 2312 away from 2343, we end up with 31.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 289

Let's proceed to step 7:
The number 289 fits into 314 1 times, leaving a remainder of 25.
The number 1 becomes the next digit in our result. 
Result so far: 23481.0
Deduct 289 from 314 and we're left with 25.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 289

On to step 8:
254 divided by 289 is 0 with a remainder of 254.
The next digit of our result is 0. 
Result so far: 234810.0
If we take 0 away from 254, we end up with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Moving on to step 9:
The number 289 fits into 2540 8 times, leaving a remainder of 228.
The number 8 becomes the next digit in our result. 
Result so far: 234810.8
Subtract 2312 from 2540 to get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Advancing to step 10:
When dividing 2280 by 289, we get 7 with a remainder of 257.
The next digit of our result is 7. 
Result so far: 234810.87
Deduct 2023 from 2280 and we're left with 257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2570, and continue the process.

On to step 11:
The number 289 fits into 2570 8 times, leaving a remainder of 258.
Record the quotient 8 as the next digit in the result. 
Result so far: 234810.878
Subtracting 2312 from 2570 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Let's proceed to step 12:
When dividing 2580 by 289, we get 8 with a remainder of 268.
Write down 8 as next digit of the result. 
Result so far: 234810.8788
Deduct 2312 from 2580 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Our division results in 234810.8788 with a remaining 0.00268.
