We look at the division of 6812216 by 345 
We want to divide 6812216 by 345.

On to step 1:
When dividing 6 by 345, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 345

Step 2:
345 goes into 68 0 times with a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Append the next digit (1) from the dividend to 68 and continue with: 681 / 345

Advancing to step 3:
345 goes into 681 1 times with a remainder of 336.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 345 from 681 and we're left with 336.
Fetch the next digit (2) from the dividend, attach it to 336 and continue: 3362 / 345

Going ahead to step 4:
345 can be fit into 3362 9 times, resulting in a remainder of 257.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 3105 from 3362 and we're left with 257.
Grab the next digit (2) from the dividend, add it to 257, then carry on: 2572 / 345

On to step 5:
2572 divided by 345 is 7 with a remainder of 157.
The number 7 becomes the next digit in our result. 
Result so far: 197.0
The remainder is 157 after subtracting 2415 from 2572.
Include the next digit (1) from the dividend after 157, then repeat: 1571 / 345

Going ahead to step 6:
If we divide 1571 by 345, we get 4 and a remainder of 191.
Use 4 as the next digit of our solution. 
Result so far: 1974.0
If we take 1380 away from 1571, we end up with 191.
Take the next digit (6) from the dividend and append it to 191, then repeat: 1916 / 345

Moving on to step 7:
1916 divided by 345 is 5 with a remainder of 191.
Write down 5 as next digit of the result. 
Result so far: 19745.0
Deduct 1725 from 1916 and we're left with 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Let's proceed to step 8:
1910 divided by 345 is 5 with a remainder of 185.
Put 5 as the next digit of the answer. 
Result so far: 19745.5
The remainder is 185 after subtracting 1725 from 1910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 9:
If we divide 1850 by 345, we get 5 and a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 19745.55
Subtracting 1725 from 1850 leaves us with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

The quotient of the division is 19745.55, and the remainder is 0.125.
