6712991 ÷ 678 
Let's see how many times 678 fits into 6712991.

On to step 1:
678 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 678

Advancing to step 2:
67 divided by 678 is 0 with a remainder of 67.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Fetch the next digit (1) from the dividend, attach it to 67 and continue: 671 / 678

Step 3:
678 can be fit into 671 0 times, resulting in a remainder of 671.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 671 after subtracting 0 from 671.
Include the next digit (2) from the dividend after 671, then repeat: 6712 / 678

Step 4:
The number 678 fits into 6712 9 times, leaving a remainder of 610.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 6102 away from 6712, we end up with 610.
Grab the next digit (9) from the dividend, add it to 610, then carry on: 6109 / 678

On to step 5:
678 goes into 6109 9 times with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 99.0
Deduct 6102 from 6109 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 678

Step 6:
79 divided by 678 is 0 with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 990.0
Subtracting 0 from 79 leaves us with 79.
Include the next digit (1) from the dividend after 79, then repeat: 791 / 678

Advancing to step 7:
If we divide 791 by 678, we get 1 and a remainder of 113.
Put 1 as the next digit of the answer. 
Result so far: 9901.0
If we take 678 away from 791, we end up with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Advancing to step 8:
When dividing 1130 by 678, we get 1 with a remainder of 452.
The number 1 becomes the next digit in our result. 
Result so far: 9901.1
If we take 678 away from 1130, we end up with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Step 9:
678 goes into 4520 6 times with a remainder of 452.
Record the quotient 6 as the next digit in the result. 
Result so far: 9901.16
Subtracting 4068 from 4520 leaves us with 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Moving on to step 10:
4520 divided by 678 is 6 with a remainder of 452.
Put 6 as the next digit of the answer. 
Result so far: 9901.166
Subtract 4068 from 4520 to get 452.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

In conclusion, the division gives 9901.166 with a balance of 0.0452.
