We're dividing 663149 by 84 
Our goal is to divide 663149 by 84.

Going ahead to step 1:
If we divide 6 by 84, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 84

Going ahead to step 2:
66 divided by 84 is 0 with a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Append the next digit (3) from the dividend to 66 and continue with: 663 / 84

Moving on to step 3:
663 divided by 84 is 7 with a remainder of 75.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 588 from 663 leaves us with 75.
Grab the next digit (1) from the dividend, add it to 75, then carry on: 751 / 84

Going ahead to step 4:
The number 84 fits into 751 8 times, leaving a remainder of 79.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
Subtract 672 from 751 to get 79.
Bring next digit (4) of the dividend behind the 79 and repeat the process: 794 / 84

Advancing to step 5:
When dividing 794 by 84, we get 9 with a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 789.0
Subtracting 756 from 794 leaves us with 38.
Take the next digit (9) from the dividend and append it to 38, then repeat: 389 / 84

Going ahead to step 6:
When dividing 389 by 84, we get 4 with a remainder of 53.
Record the quotient 4 as the next digit in the result. 
Result so far: 7894.0
The remainder is 53 after subtracting 336 from 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 7:
84 can be fit into 530 6 times, resulting in a remainder of 26.
The number 6 becomes the next digit in our result. 
Result so far: 7894.6
Subtracting 504 from 530 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
84 goes into 260 3 times with a remainder of 8.
The next digit of our result is 3. 
Result so far: 7894.63
If we subtract 252 from 260, 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.

Step 9:
If we divide 80 by 84, we get 0 and a remainder of 80.
The next digit of our result is 0. 
Result so far: 7894.63
If we take 0 away from 80, we end up 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.

Let's proceed to step 10:
84 can be fit into 800 9 times, resulting in a remainder of 44.
The number 9 becomes the next digit in our result. 
Result so far: 7894.6309
If we subtract 756 from 800, we 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.

Moving on to step 11:
84 goes into 440 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 7894.63095
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.

On to step 12:
When dividing 200 by 84, we get 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 7894.630952
Deduct 168 from 200 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 13:
If we divide 320 by 84, we get 3 and a remainder of 68.
The number 3 becomes the next digit in our result. 
Result so far: 7894.6309523
Subtract 252 from 320 to get 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 14:
84 can be fit into 680 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 7894.63095238
The remainder is 8 after subtracting 672 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 7894.63095238, with a leftover of 8e-09.
