7070109 ÷ 878 
We're looking to find how many times 878 goes into 7070109.

On to step 1:
7 divided by 878 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 878

Step 2:
878 goes into 70 0 times with a remainder of 70.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 70 after subtracting 0 from 70.
Bring next digit (7) of the dividend behind the 70 and repeat the process: 707 / 878

Advancing to step 3:
If we divide 707 by 878, we get 0 and a remainder of 707.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 707 and we're left with 707.
Bring next digit (0) of the dividend behind the 707 and repeat the process: 7070 / 878

Let's proceed to step 4:
878 goes into 7070 8 times with a remainder of 46.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 46 after subtracting 7024 from 7070.
Take the next digit (1) from the dividend and append it to 46, then repeat: 461 / 878

Let's proceed to step 5:
The number 878 fits into 461 0 times, leaving a remainder of 461.
Record the quotient 0 as the next digit in the result. 
Result so far: 80.0
Subtracting 0 from 461 leaves us with 461.
Take the next digit (0) from the dividend and append it to 461, then repeat: 4610 / 878

Step 6:
4610 divided by 878 is 5 with a remainder of 220.
Record the quotient 5 as the next digit in the result. 
Result so far: 805.0
Deduct 4390 from 4610 and we're left with 220.
Append the next digit (9) from the dividend to 220 and continue with: 2209 / 878

Let's proceed to step 7:
The number 878 fits into 2209 2 times, leaving a remainder of 453.
The next digit of our result is 2. 
Result so far: 8052.0
If we take 1756 away from 2209, we end up with 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Step 8:
The number 878 fits into 4530 5 times, leaving a remainder of 140.
Use 5 as the next digit of our solution. 
Result so far: 8052.5
The remainder is 140 after subtracting 4390 from 4530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 9:
878 can be fit into 1400 1 times, resulting in a remainder of 522.
The number 1 becomes the next digit in our result. 
Result so far: 8052.51
If we take 878 away from 1400, we end up with 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Going ahead to step 10:
878 can be fit into 5220 5 times, resulting in a remainder of 830.
Use 5 as the next digit of our solution. 
Result so far: 8052.515
Deduct 4390 from 5220 and we're left with 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Advancing to step 11:
8300 divided by 878 is 9 with a remainder of 398.
Record the quotient 9 as the next digit in the result. 
Result so far: 8052.5159
If we take 7902 away from 8300, we end up with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Let's proceed to step 12:
878 can be fit into 3980 4 times, resulting in a remainder of 468.
The next digit of our result is 4. 
Result so far: 8052.51594
Subtract 3512 from 3980 to get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Step 13:
878 can be fit into 4680 5 times, resulting in a remainder of 290.
Put 5 as the next digit of the answer. 
Result so far: 8052.515945
If we take 4390 away from 4680, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Going ahead to step 14:
878 goes into 2900 3 times with a remainder of 266.
The number 3 becomes the next digit in our result. 
Result so far: 8052.5159453
Subtracting 2634 from 2900 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Moving on to step 15:
878 can be fit into 2660 3 times, resulting in a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 8052.51594533
Subtracting 2634 from 2660 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.

In conclusion, the division gives 8052.51594533 with a balance of 2.6e-08.
