Moving on to step 3:
The number 878 fits into 862 0 times, leaving a remainder of 862.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 862 to get 862.
Grab the next digit (1) from the dividend, add it to 862, then carry on: 8621 / 878

Moving on to step 4:
878 goes into 8621 9 times with a remainder of 719.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 7902 from 8621 and we're left with 719.
Take the next digit (4) from the dividend and append it to 719, then repeat: 7194 / 878

Step 5:
7194 divided by 878 is 8 with a remainder of 170.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
If we subtract 7024 from 7194, we get 170.
Include the next digit (4) from the dividend after 170, then repeat: 1704 / 878

Advancing to step 6:
If we divide 1704 by 878, we get 1 and a remainder of 826.
Put 1 as the next digit of the answer. 
Result so far: 981.0
Subtract 878 from 1704 to get 826.
Fetch the next digit (5) from the dividend, attach it to 826 and continue: 8265 / 878

Moving on to step 7:
8265 divided by 878 is 9 with a remainder of 363.
The number 9 becomes the next digit in our result. 
Result so far: 9819.0
Subtracting 7902 from 8265 leaves us with 363.
Fetch the next digit (8) from the dividend, attach it to 363 and continue: 3638 / 878

Going ahead to step 8:
3638 divided by 878 is 4 with a remainder of 126.
Write down 4 as next digit of the result. 
Result so far: 98194.0
Subtract 3512 from 3638 to get 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Moving on to step 9:
878 can be fit into 1260 1 times, resulting in a remainder of 382.
Write down 1 as next digit of the result. 
Result so far: 98194.1
Subtract 878 from 1260 to get 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Advancing to step 10:
878 goes into 3820 4 times with a remainder of 308.
The number 4 becomes the next digit in our result. 
Result so far: 98194.14
The remainder is 308 after subtracting 3512 from 3820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Advancing to step 11:
If we divide 3080 by 878, we get 3 and a remainder of 446.
The next digit of our result is 3. 
Result so far: 98194.143
The remainder is 446 after subtracting 2634 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Let's proceed to step 12:
If we divide 4460 by 878, we get 5 and a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 98194.1435
If we subtract 4390 from 4460, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 13:
The number 878 fits into 700 0 times, leaving a remainder of 700.
Use 0 as the next digit of our solution. 
Result so far: 98194.1435
Subtracting 0 from 700 leaves us with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 14:
When dividing 7000 by 878, we get 7 with a remainder of 854.
Use 7 as the next digit of our solution. 
Result so far: 98194.143507
If we subtract 6146 from 7000, we get 854.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8540, and continue the process.

Step 15:
If we divide 8540 by 878, we get 9 and a remainder of 638.
Use 9 as the next digit of our solution. 
Result so far: 98194.1435079
Subtract 7902 from 8540 to get 638.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6380, and continue the process.

Advancing to step 16:
878 can be fit into 6380 7 times, resulting in a remainder of 234.
The number 7 becomes the next digit in our result. 
Result so far: 98194.14350797
Subtract 6146 from 6380 to get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

The final outcome is 98194.14350797, with a leftover of 2.34e-07.
