We're dividing 70387890 by 780 
Our goal is to divide 70387890 by 780.

Let's proceed to step 1:
7 divided by 780 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 780

Let's proceed to step 2:
780 goes into 70 0 times with a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 70, we end up with 70.
Include the next digit (3) from the dividend after 70, then repeat: 703 / 780

Let's proceed to step 3:
When dividing 703 by 780, we get 0 with a remainder of 703.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 703 leaves us with 703.
Include the next digit (8) from the dividend after 703, then repeat: 7038 / 780

Advancing to step 4:
When dividing 7038 by 780, we get 9 with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 9.0
The remainder is 18 after subtracting 7020 from 7038.
Append the next digit (7) from the dividend to 18 and continue with: 187 / 780

Moving on to step 5:
The number 780 fits into 187 0 times, leaving a remainder of 187.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
The remainder is 187 after subtracting 0 from 187.
Include the next digit (8) from the dividend after 187, then repeat: 1878 / 780

On to step 6:
780 can be fit into 1878 2 times, resulting in a remainder of 318.
The number 2 becomes the next digit in our result. 
Result so far: 902.0
If we take 1560 away from 1878, we end up with 318.
Append the next digit (9) from the dividend to 318 and continue with: 3189 / 780

On to step 7:
3189 divided by 780 is 4 with a remainder of 69.
Put 4 as the next digit of the answer. 
Result so far: 9024.0
Subtract 3120 from 3189 to get 69.
Append the next digit (0) from the dividend to 69 and continue with: 690 / 780

Step 8:
When dividing 690 by 780, we get 0 with a remainder of 690.
The number 0 becomes the next digit in our result. 
Result so far: 90240.0
If we take 0 away from 690, we end up with 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6900, and continue the process.

On to step 9:
When dividing 6900 by 780, we get 8 with a remainder of 660.
Use 8 as the next digit of our solution. 
Result so far: 90240.8
The remainder is 660 after subtracting 6240 from 6900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Going ahead to step 10:
The number 780 fits into 6600 8 times, leaving a remainder of 360.
Use 8 as the next digit of our solution. 
Result so far: 90240.88
The remainder is 360 after subtracting 6240 from 6600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

The quotient of the division is 90240.88, and the remainder is 0.36.
