We're dividing 25965535 by 390 
We want to divide 25965535 by 390.

Advancing to step 1:
If we divide 2 by 390, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 390

Step 2:
390 goes into 25 0 times with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Bring next digit (9) of the dividend behind the 25 and repeat the process: 259 / 390

Going ahead to step 3:
If we divide 259 by 390, we get 0 and a remainder of 259.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 259 to get 259.
Take the next digit (6) from the dividend and append it to 259, then repeat: 2596 / 390

On to step 4:
When dividing 2596 by 390, we get 6 with a remainder of 256.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 2340 from 2596 leaves us with 256.
Append the next digit (5) from the dividend to 256 and continue with: 2565 / 390

Moving on to step 5:
390 goes into 2565 6 times with a remainder of 225.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
Subtract 2340 from 2565 to get 225.
Include the next digit (5) from the dividend after 225, then repeat: 2255 / 390

Going ahead to step 6:
2255 divided by 390 is 5 with a remainder of 305.
Use 5 as the next digit of our solution. 
Result so far: 665.0
If we take 1950 away from 2255, we end up with 305.
Fetch the next digit (3) from the dividend, attach it to 305 and continue: 3053 / 390

Going ahead to step 7:
If we divide 3053 by 390, we get 7 and a remainder of 323.
Use 7 as the next digit of our solution. 
Result so far: 6657.0
The remainder is 323 after subtracting 2730 from 3053.
Append the next digit (5) from the dividend to 323 and continue with: 3235 / 390

Moving on to step 8:
390 can be fit into 3235 8 times, resulting in a remainder of 115.
Put 8 as the next digit of the answer. 
Result so far: 66578.0
If we take 3120 away from 3235, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Moving on to step 9:
390 goes into 1150 2 times with a remainder of 370.
Record the quotient 2 as the next digit in the result. 
Result so far: 66578.2
Subtract 780 from 1150 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 10:
390 can be fit into 3700 9 times, resulting in a remainder of 190.
Put 9 as the next digit of the answer. 
Result so far: 66578.29
Subtract 3510 from 3700 to get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 11:
1900 divided by 390 is 4 with a remainder of 340.
Use 4 as the next digit of our solution. 
Result so far: 66578.294
If we subtract 1560 from 1900, we get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Advancing to step 12:
390 goes into 3400 8 times with a remainder of 280.
Write down 8 as next digit of the result. 
Result so far: 66578.2948
The remainder is 280 after subtracting 3120 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Moving on to step 13:
When dividing 2800 by 390, we get 7 with a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 66578.29487
If we subtract 2730 from 2800, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 14:
390 goes into 700 1 times with a remainder of 310.
Record the quotient 1 as the next digit in the result. 
Result so far: 66578.294871
Subtract 390 from 700 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

On to step 15:
If we divide 3100 by 390, we get 7 and a remainder of 370.
Use 7 as the next digit of our solution. 
Result so far: 66578.2948717
If we subtract 2730 from 3100, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Moving on to step 16:
390 goes into 3700 9 times with a remainder of 190.
Use 9 as the next digit of our solution. 
Result so far: 66578.29487179
If we take 3510 away from 3700, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

The final outcome is 66578.29487179, with a leftover of 1.9e-07.
