If we subtract 0 from 4, we get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 840

Let's proceed to step 2:
840 goes into 45 0 times with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Fetch the next digit (7) from the dividend, attach it to 45 and continue: 457 / 840

Going ahead to step 3:
457 divided by 840 is 0 with a remainder of 457.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 457 and we're left with 457.
Append the next digit (5) from the dividend to 457 and continue with: 4575 / 840

Advancing to step 4:
4575 divided by 840 is 5 with a remainder of 375.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 4200 from 4575, we get 375.
Take the next digit (9) from the dividend and append it to 375, then repeat: 3759 / 840

Step 5:
840 can be fit into 3759 4 times, resulting in a remainder of 399.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
If we take 3360 away from 3759, we end up with 399.
Append the next digit (5) from the dividend to 399 and continue with: 3995 / 840

Moving on to step 6:
The number 840 fits into 3995 4 times, leaving a remainder of 635.
The number 4 becomes the next digit in our result. 
Result so far: 544.0
Subtract 3360 from 3995 to get 635.
Bring next digit (6) of the dividend behind the 635 and repeat the process: 6356 / 840

Step 7:
6356 divided by 840 is 7 with a remainder of 476.
Use 7 as the next digit of our solution. 
Result so far: 5447.0
Subtracting 5880 from 6356 leaves us with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Let's proceed to step 8:
When dividing 4760 by 840, we get 5 with a remainder of 560.
Write down 5 as next digit of the result. 
Result so far: 5447.5
Subtracting 4200 from 4760 leaves us with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 9:
The number 840 fits into 5600 6 times, leaving a remainder of 560.
Record the quotient 6 as the next digit in the result. 
Result so far: 5447.56
Deduct 5040 from 5600 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Let's proceed to step 10:
5600 divided by 840 is 6 with a remainder of 560.
Write down 6 as next digit of the result. 
Result so far: 5447.566
If we take 5040 away from 5600, we end up with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

After the division, we end up with 5447.566 and a remainder of 0.056.
