678910 ÷ 99 
We want to divide 678910 by 99.

Let's proceed to step 1:
The number 99 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 99

Step 2:
99 goes into 67 0 times with a remainder of 67.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 67, we end up with 67.
Include the next digit (8) from the dividend after 67, then repeat: 678 / 99

Step 3:
678 divided by 99 is 6 with a remainder of 84.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 594 from 678 and we're left with 84.
Grab the next digit (9) from the dividend, add it to 84, then carry on: 849 / 99

Let's proceed to step 4:
When dividing 849 by 99, we get 8 with a remainder of 57.
The number 8 becomes the next digit in our result. 
Result so far: 68.0
If we subtract 792 from 849, we get 57.
Append the next digit (1) from the dividend to 57 and continue with: 571 / 99

Advancing to step 5:
The number 99 fits into 571 5 times, leaving a remainder of 76.
Write down 5 as next digit of the result. 
Result so far: 685.0
Subtract 495 from 571 to get 76.
Take the next digit (0) from the dividend and append it to 76, then repeat: 760 / 99

Let's proceed to step 6:
99 can be fit into 760 7 times, resulting in a remainder of 67.
Write down 7 as next digit of the result. 
Result so far: 6857.0
Subtract 693 from 760 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 7:
99 goes into 670 6 times with a remainder of 76.
Use 6 as the next digit of our solution. 
Result so far: 6857.6
The remainder is 76 after subtracting 594 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 8:
When dividing 760 by 99, we get 7 with a remainder of 67.
Use 7 as the next digit of our solution. 
Result so far: 6857.67
If we subtract 693 from 760, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 9:
When dividing 670 by 99, we get 6 with a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 6857.676
The remainder is 76 after subtracting 594 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 10:
99 can be fit into 760 7 times, resulting in a remainder of 67.
Put 7 as the next digit of the answer. 
Result so far: 6857.6767
The remainder is 67 after subtracting 693 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Step 11:
If we divide 670 by 99, we get 6 and a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 6857.67676
If we subtract 594 from 670, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 12:
760 divided by 99 is 7 with a remainder of 67.
The next digit of our result is 7. 
Result so far: 6857.676767
The remainder is 67 after subtracting 693 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 13:
When dividing 670 by 99, we get 6 with a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 6857.6767676
If we take 594 away from 670, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 14:
99 can be fit into 760 7 times, resulting in a remainder of 67.
Put 7 as the next digit of the answer. 
Result so far: 6857.67676767
If we take 693 away from 760, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

After the division, we end up with 6857.67676767 and a remainder of 6.7e-08.
