We look at the division of 70278174 by 780 
We want to figure out the number of times 70278174 can be divided by 780.

Step 1:
780 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 780

Let's proceed to step 2:
When dividing 70 by 780, we get 0 with a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 70 and we're left with 70.
Fetch the next digit (2) from the dividend, attach it to 70 and continue: 702 / 780

On to step 3:
702 divided by 780 is 0 with a remainder of 702.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 702 after subtracting 0 from 702.
Append the next digit (7) from the dividend to 702 and continue with: 7027 / 780

On to step 4:
780 can be fit into 7027 9 times, resulting in a remainder of 7.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 7020 from 7027, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 780

Moving on to step 5:
780 goes into 78 0 times with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 90.0
If we subtract 0 from 78, we get 78.
Take the next digit (1) from the dividend and append it to 78, then repeat: 781 / 780

Moving on to step 6:
781 divided by 780 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 901.0
If we subtract 780 from 781, we get 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 780

Moving on to step 7:
780 can be fit into 17 0 times, resulting in a remainder of 17.
The next digit of our result is 0. 
Result so far: 9010.0
Subtract 0 from 17 to get 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 780

Advancing to step 8:
When dividing 174 by 780, we get 0 with a remainder of 174.
Put 0 as the next digit of the answer. 
Result so far: 90100.0
If we take 0 away from 174, we end up with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Let's proceed to step 9:
780 goes into 1740 2 times with a remainder of 180.
The next digit of our result is 2. 
Result so far: 90100.2
If we take 1560 away from 1740, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

On to step 10:
780 can be fit into 1800 2 times, resulting in a remainder of 240.
The number 2 becomes the next digit in our result. 
Result so far: 90100.22
The remainder is 240 after subtracting 1560 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

After the division, we end up with 90100.22 and a remainder of 0.24.
