678189 ÷ 84 
We're looking to find how many times 84 goes into 678189.

Moving on to step 1:
84 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 84

Moving on to step 2:
The number 84 fits into 67 0 times, leaving 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.
Bring next digit (8) of the dividend behind the 67 and repeat the process: 678 / 84

Let's proceed to step 3:
When dividing 678 by 84, we get 8 with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 672 from 678 and we're left with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 84

Moving on to step 4:
The number 84 fits into 61 0 times, leaving a remainder of 61.
The next digit of our result is 0. 
Result so far: 80.0
Subtracting 0 from 61 leaves us with 61.
Fetch the next digit (8) from the dividend, attach it to 61 and continue: 618 / 84

Step 5:
If we divide 618 by 84, we get 7 and a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 807.0
Deduct 588 from 618 and we're left with 30.
Bring next digit (9) of the dividend behind the 30 and repeat the process: 309 / 84

Step 6:
84 goes into 309 3 times with a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 8073.0
If we take 252 away from 309, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 7:
If we divide 570 by 84, we get 6 and a remainder of 66.
Use 6 as the next digit of our solution. 
Result so far: 8073.6
If we subtract 504 from 570, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 8:
If we divide 660 by 84, we get 7 and a remainder of 72.
Record the quotient 7 as the next digit in the result. 
Result so far: 8073.67
Subtract 588 from 660 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 9:
When dividing 720 by 84, we get 8 with a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 8073.678
If we take 672 away from 720, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
84 goes into 480 5 times with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 8073.6785
If we subtract 420 from 480, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
If we divide 600 by 84, we get 7 and a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 8073.67857
Subtract 588 from 600 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
84 can be fit into 120 1 times, resulting in a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 8073.678571
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
84 goes into 360 4 times with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 8073.6785714
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
If we divide 240 by 84, we get 2 and a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 8073.67857142
If we subtract 168 from 240, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 8073.67857142 with a remainder of 7.2e-08.
