673679 ÷ 84 
Our goal is to divide 673679 by 84.

Going ahead to step 1:
The number 84 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 84

Advancing to step 2:
When dividing 67 by 84, we get 0 with a remainder of 67.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 67 leaves us with 67.
Take the next digit (3) from the dividend and append it to 67, then repeat: 673 / 84

Advancing to step 3:
84 goes into 673 8 times with a remainder of 1.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 672 from 673 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 84

Advancing to step 4:
When dividing 16 by 84, we get 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Subtracting 0 from 16 leaves us with 16.
Fetch the next digit (7) from the dividend, attach it to 16 and continue: 167 / 84

On to step 5:
167 divided by 84 is 1 with a remainder of 83.
Record the quotient 1 as the next digit in the result. 
Result so far: 801.0
If we subtract 84 from 167, we get 83.
Fetch the next digit (9) from the dividend, attach it to 83 and continue: 839 / 84

On to step 6:
84 can be fit into 839 9 times, resulting in a remainder of 83.
Write down 9 as next digit of the result. 
Result so far: 8019.0
If we take 756 away from 839, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Step 7:
If we divide 830 by 84, we get 9 and a remainder of 74.
Write down 9 as next digit of the result. 
Result so far: 8019.9
Deduct 756 from 830 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 8:
84 goes into 740 8 times with a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 8019.98
Deduct 672 from 740 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 9:
If we divide 680 by 84, we get 8 and a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 8019.988
Subtract 672 from 680 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 8019.988 with a remaining 0.0008.
