Let's divide 25953071 by 390
We want to divide 25953071 by 390.

Going ahead to step 1:
If we divide 2 by 390, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 390

Advancing to step 2:
When dividing 25 by 390, we get 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 390

Let's proceed to step 3:
The number 390 fits into 259 0 times, leaving a remainder of 259.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 259 and we're left with 259.
Bring next digit (5) of the dividend behind the 259 and repeat the process: 2595 / 390

Advancing to step 4:
2595 divided by 390 is 6 with a remainder of 255.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtract 2340 from 2595 to get 255.
Include the next digit (3) from the dividend after 255, then repeat: 2553 / 390

Moving on to step 5:
The number 390 fits into 2553 6 times, leaving a remainder of 213.
Use 6 as the next digit of our solution. 
Result so far: 66.0
If we take 2340 away from 2553, we end up with 213.
Fetch the next digit (0) from the dividend, attach it to 213 and continue: 2130 / 390

Step 6:
390 goes into 2130 5 times with a remainder of 180.
Put 5 as the next digit of the answer. 
Result so far: 665.0
If we subtract 1950 from 2130, we get 180.
Grab the next digit (7) from the dividend, add it to 180, then carry on: 1807 / 390

Step 7:
If we divide 1807 by 390, we get 4 and a remainder of 247.
Put 4 as the next digit of the answer. 
Result so far: 6654.0
Subtract 1560 from 1807 to get 247.
Bring next digit (1) of the dividend behind the 247 and repeat the process: 2471 / 390

Let's proceed to step 8:
When dividing 2471 by 390, we get 6 with a remainder of 131.
Use 6 as the next digit of our solution. 
Result so far: 66546.0
Subtracting 2340 from 2471 leaves us with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 9:
1310 divided by 390 is 3 with a remainder of 140.
Write down 3 as next digit of the result. 
Result so far: 66546.3
Subtract 1170 from 1310 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Step 10:
390 goes into 1400 3 times with a remainder of 230.
Put 3 as the next digit of the answer. 
Result so far: 66546.33
Subtract 1170 from 1400 to get 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

The final outcome is 66546.33, with a leftover of 0.23.
