Take the next digit (7) from the dividend and append it to 554, then repeat: 5547 / 840

Advancing to step 4:
840 goes into 5547 6 times with a remainder of 507.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 5040 from 5547 and we're left with 507.
Take the next digit (6) from the dividend and append it to 507, then repeat: 5076 / 840

Going ahead to step 5:
5076 divided by 840 is 6 with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 66.0
If we subtract 5040 from 5076, we get 36.
Bring next digit (4) of the dividend behind the 36 and repeat the process: 364 / 840

Let's proceed to step 6:
When dividing 364 by 840, we get 0 with a remainder of 364.
Record the quotient 0 as the next digit in the result. 
Result so far: 660.0
Subtract 0 from 364 to get 364.
Include the next digit (2) from the dividend after 364, then repeat: 3642 / 840

Let's proceed to step 7:
840 can be fit into 3642 4 times, resulting in a remainder of 282.
The next digit of our result is 4. 
Result so far: 6604.0
If we subtract 3360 from 3642, we get 282.
Append the next digit (9) from the dividend to 282 and continue with: 2829 / 840

Moving on to step 8:
840 can be fit into 2829 3 times, resulting in a remainder of 309.
Write down 3 as next digit of the result. 
Result so far: 66043.0
Subtract 2520 from 2829 to get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

On to step 9:
3090 divided by 840 is 3 with a remainder of 570.
The next digit of our result is 3. 
Result so far: 66043.3
The remainder is 570 after subtracting 2520 from 3090.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5700, and continue the process.

On to step 10:
840 can be fit into 5700 6 times, resulting in a remainder of 660.
Write down 6 as next digit of the result. 
Result so far: 66043.36
Subtracting 5040 from 5700 leaves us with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Advancing to step 11:
The number 840 fits into 6600 7 times, leaving a remainder of 720.
Put 7 as the next digit of the answer. 
Result so far: 66043.367
Subtracting 5880 from 6600 leaves us with 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Step 12:
840 goes into 7200 8 times with a remainder of 480.
Write down 8 as next digit of the result. 
Result so far: 66043.3678
Subtracting 6720 from 7200 leaves us with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Moving on to step 13:
When dividing 4800 by 840, we get 5 with a remainder of 600.
The number 5 becomes the next digit in our result. 
Result so far: 66043.36785
The remainder is 600 after subtracting 4200 from 4800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 14:
840 can be fit into 6000 7 times, resulting in a remainder of 120.
Put 7 as the next digit of the answer. 
Result so far: 66043.367857
If we subtract 5880 from 6000, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 15:
The number 840 fits into 1200 1 times, leaving a remainder of 360.
Put 1 as the next digit of the answer. 
Result so far: 66043.3678571
Deduct 840 from 1200 and we're left with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Step 16:
The number 840 fits into 3600 4 times, leaving a remainder of 240.
Use 4 as the next digit of our solution. 
Result so far: 66043.36785714
Subtract 3360 from 3600 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

The quotient of the division is 66043.36785714, and the remainder is 2.4e-07.
