815678 ÷ 84 
Our goal is to divide 815678 by 84.

On to step 1:
The number 84 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 84

Advancing to step 2:
84 can be fit into 81 0 times, resulting in a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Include the next digit (5) from the dividend after 81, then repeat: 815 / 84

Going ahead to step 3:
If we divide 815 by 84, we get 9 and a remainder of 59.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 59 after subtracting 756 from 815.
Append the next digit (6) from the dividend to 59 and continue with: 596 / 84

Moving on to step 4:
When dividing 596 by 84, we get 7 with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
If we subtract 588 from 596, we get 8.
Fetch the next digit (7) from the dividend, attach it to 8 and continue: 87 / 84

Step 5:
When dividing 87 by 84, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 971.0
The remainder is 3 after subtracting 84 from 87.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 84

Advancing to step 6:
38 divided by 84 is 0 with a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 9710.0
If we subtract 0 from 38, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 7:
84 goes into 380 4 times with a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 9710.4
Subtracting 336 from 380 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 8:
440 divided by 84 is 5 with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 9710.45
If we subtract 420 from 440, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
84 can be fit into 200 2 times, resulting in a remainder of 32.
The next digit of our result is 2. 
Result so far: 9710.452
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 10:
When dividing 320 by 84, we get 3 with a remainder of 68.
Put 3 as the next digit of the answer. 
Result so far: 9710.4523
If we take 252 away from 320, we end up 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.

Advancing to step 11:
84 can be fit into 680 8 times, resulting in a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 9710.45238
If we subtract 672 from 680, we 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.

Going ahead to step 12:
84 can be fit into 80 0 times, resulting in a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 9710.45238
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
84 can be fit into 800 9 times, resulting in a remainder of 44.
The next digit of our result is 9. 
Result so far: 9710.4523809
Subtract 756 from 800 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 14:
440 divided by 84 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 9710.45238095
Subtracting 420 from 440 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 9710.45238095 with a remainder of 2e-08.
