If we subtract 0 from 4, we get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 878

On to step 2:
When dividing 45 by 878, we get 0 with a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Append the next digit (7) from the dividend to 45 and continue with: 457 / 878

Going ahead to step 3:
If we divide 457 by 878, we get 0 and a remainder of 457.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 457 to get 457.
Take the next digit (5) from the dividend and append it to 457, then repeat: 4575 / 878

On to step 4:
4575 divided by 878 is 5 with a remainder of 185.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 4390 from 4575 and we're left with 185.
Take the next digit (5) from the dividend and append it to 185, then repeat: 1855 / 878

Moving on to step 5:
If we divide 1855 by 878, we get 2 and a remainder of 99.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
If we subtract 1756 from 1855, we get 99.
Append the next digit (8) from the dividend to 99 and continue with: 998 / 878

Let's proceed to step 6:
The number 878 fits into 998 1 times, leaving a remainder of 120.
Use 1 as the next digit of our solution. 
Result so far: 521.0
If we subtract 878 from 998, we get 120.
Fetch the next digit (8) from the dividend, attach it to 120 and continue: 1208 / 878

Going ahead to step 7:
When dividing 1208 by 878, we get 1 with a remainder of 330.
Put 1 as the next digit of the answer. 
Result so far: 5211.0
If we subtract 878 from 1208, we get 330.
Include the next digit (8) from the dividend after 330, then repeat: 3308 / 878

Moving on to step 8:
878 goes into 3308 3 times with a remainder of 674.
The next digit of our result is 3. 
Result so far: 52113.0
If we take 2634 away from 3308, we end up with 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

Moving on to step 9:
The number 878 fits into 6740 7 times, leaving a remainder of 594.
Put 7 as the next digit of the answer. 
Result so far: 52113.7
The remainder is 594 after subtracting 6146 from 6740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

On to step 10:
878 can be fit into 5940 6 times, resulting in a remainder of 672.
The number 6 becomes the next digit in our result. 
Result so far: 52113.76
If we subtract 5268 from 5940, we get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Going ahead to step 11:
When dividing 6720 by 878, we get 7 with a remainder of 574.
Write down 7 as next digit of the result. 
Result so far: 52113.767
The remainder is 574 after subtracting 6146 from 6720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5740, and continue the process.

Going ahead to step 12:
When dividing 5740 by 878, we get 6 with a remainder of 472.
The next digit of our result is 6. 
Result so far: 52113.7676
Deduct 5268 from 5740 and we're left with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 13:
878 goes into 4720 5 times with a remainder of 330.
Put 5 as the next digit of the answer. 
Result so far: 52113.76765
Deduct 4390 from 4720 and we're left with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Advancing to step 14:
878 can be fit into 3300 3 times, resulting in a remainder of 666.
The next digit of our result is 3. 
Result so far: 52113.767653
Subtracting 2634 from 3300 leaves us with 666.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6660, and continue the process.

Advancing to step 15:
If we divide 6660 by 878, we get 7 and a remainder of 514.
The number 7 becomes the next digit in our result. 
Result so far: 52113.7676537
The remainder is 514 after subtracting 6146 from 6660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Going ahead to step 16:
878 goes into 5140 5 times with a remainder of 750.
The next digit of our result is 5. 
Result so far: 52113.76765375
If we take 4390 away from 5140, we end up with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

In conclusion, the division gives 52113.76765375 with a balance of 7.5e-07.
