34378767 ÷ 287 
Our goal is to divide 34378767 by 287.

Step 1:
When dividing 3 by 287, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 287

On to step 2:
287 goes into 34 0 times with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Append the next digit (3) from the dividend to 34 and continue with: 343 / 287

Advancing to step 3:
287 goes into 343 1 times with a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 56 after subtracting 287 from 343.
Fetch the next digit (7) from the dividend, attach it to 56 and continue: 567 / 287

Moving on to step 4:
287 can be fit into 567 1 times, resulting in a remainder of 280.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 287 from 567 leaves us with 280.
Take the next digit (8) from the dividend and append it to 280, then repeat: 2808 / 287

Moving on to step 5:
If we divide 2808 by 287, we get 9 and a remainder of 225.
Write down 9 as next digit of the result. 
Result so far: 119.0
Subtract 2583 from 2808 to get 225.
Grab the next digit (7) from the dividend, add it to 225, then carry on: 2257 / 287

Going ahead to step 6:
If we divide 2257 by 287, we get 7 and a remainder of 248.
Put 7 as the next digit of the answer. 
Result so far: 1197.0
Subtracting 2009 from 2257 leaves us with 248.
Append the next digit (6) from the dividend to 248 and continue with: 2486 / 287

Let's proceed to step 7:
287 goes into 2486 8 times with a remainder of 190.
Write down 8 as next digit of the result. 
Result so far: 11978.0
If we subtract 2296 from 2486, we get 190.
Append the next digit (7) from the dividend to 190 and continue with: 1907 / 287

On to step 8:
When dividing 1907 by 287, we get 6 with a remainder of 185.
The next digit of our result is 6. 
Result so far: 119786.0
Subtracting 1722 from 1907 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 9:
The number 287 fits into 1850 6 times, leaving a remainder of 128.
The next digit of our result is 6. 
Result so far: 119786.6
Subtract 1722 from 1850 to get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 10:
287 can be fit into 1280 4 times, resulting in a remainder of 132.
The next digit of our result is 4. 
Result so far: 119786.64
Subtract 1148 from 1280 to get 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 11:
If we divide 1320 by 287, we get 4 and a remainder of 172.
The next digit of our result is 4. 
Result so far: 119786.644
Subtract 1148 from 1320 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

After the division, we end up with 119786.644 and a remainder of 0.0172.
