Let's divide 343090 by 278
We're looking to find how many times 278 goes into 343090.

Step 1:
3 divided by 278 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 278

Moving on to step 2:
When dividing 34 by 278, we get 0 with a remainder of 34.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Grab the next digit (3) from the dividend, add it to 34, then carry on: 343 / 278

Going ahead to step 3:
If we divide 343 by 278, we get 1 and a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 278 from 343 and we're left with 65.
Fetch the next digit (0) from the dividend, attach it to 65 and continue: 650 / 278

Advancing to step 4:
650 divided by 278 is 2 with a remainder of 94.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 556 from 650 to get 94.
Bring next digit (9) of the dividend behind the 94 and repeat the process: 949 / 278

Moving on to step 5:
The number 278 fits into 949 3 times, leaving a remainder of 115.
Use 3 as the next digit of our solution. 
Result so far: 123.0
The remainder is 115 after subtracting 834 from 949.
Append the next digit (0) from the dividend to 115 and continue with: 1150 / 278

Let's proceed to step 6:
1150 divided by 278 is 4 with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 1234.0
If we take 1112 away from 1150, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 7:
When dividing 380 by 278, we get 1 with a remainder of 102.
The number 1 becomes the next digit in our result. 
Result so far: 1234.1
If we take 278 away from 380, we end up with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 8:
1020 divided by 278 is 3 with a remainder of 186.
Record the quotient 3 as the next digit in the result. 
Result so far: 1234.13
If we take 834 away from 1020, 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.

Let's proceed to step 9:
1860 divided by 278 is 6 with a remainder of 192.
Put 6 as the next digit of the answer. 
Result so far: 1234.136
Subtract 1668 from 1860 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 10:
1920 divided by 278 is 6 with a remainder of 252.
Write down 6 as next digit of the result. 
Result so far: 1234.1366
Subtracting 1668 from 1920 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

In conclusion, the division gives 1234.1366 with a balance of 0.00252.
