78794950 ÷ 390 
Our goal is to divide 78794950 by 390.

Let's proceed to step 1:
The number 390 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 390

Let's proceed to step 2:
390 goes into 78 0 times with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (7) from the dividend, add it to 78, then carry on: 787 / 390

Advancing to step 3:
The number 390 fits into 787 2 times, leaving a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 780 from 787 to get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 390

Advancing to step 4:
If we divide 79 by 390, we get 0 and a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 20.0
If we take 0 away from 79, we end up with 79.
Bring next digit (4) of the dividend behind the 79 and repeat the process: 794 / 390

Step 5:
When dividing 794 by 390, we get 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 202.0
Subtracting 780 from 794 leaves us with 14.
Grab the next digit (9) from the dividend, add it to 14, then carry on: 149 / 390

Step 6:
149 divided by 390 is 0 with a remainder of 149.
Record the quotient 0 as the next digit in the result. 
Result so far: 2020.0
The remainder is 149 after subtracting 0 from 149.
Grab the next digit (5) from the dividend, add it to 149, then carry on: 1495 / 390

Advancing to step 7:
1495 divided by 390 is 3 with a remainder of 325.
Record the quotient 3 as the next digit in the result. 
Result so far: 20203.0
If we take 1170 away from 1495, we end up with 325.
Append the next digit (0) from the dividend to 325 and continue with: 3250 / 390

Moving on to step 8:
The number 390 fits into 3250 8 times, leaving a remainder of 130.
The number 8 becomes the next digit in our result. 
Result so far: 202038.0
Subtract 3120 from 3250 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Going ahead to step 9:
The number 390 fits into 1300 3 times, leaving a remainder of 130.
Record the quotient 3 as the next digit in the result. 
Result so far: 202038.3
Deduct 1170 from 1300 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Let's proceed to step 10:
When dividing 1300 by 390, we get 3 with a remainder of 130.
Record the quotient 3 as the next digit in the result. 
Result so far: 202038.33
Subtract 1170 from 1300 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

The quotient of the division is 202038.33, and the remainder is 0.13.
