We divide 25388179 by 660
We're looking to find how many times 660 goes into 25388179.

Advancing to step 1:
660 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 660

Going ahead to step 2:
The number 660 fits into 25 0 times, leaving 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 (3) of the dividend behind the 25 and repeat the process: 253 / 660

Moving on to step 3:
When dividing 253 by 660, we get 0 with a remainder of 253.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 253, we get 253.
Fetch the next digit (8) from the dividend, attach it to 253 and continue: 2538 / 660

Going ahead to step 4:
2538 divided by 660 is 3 with a remainder of 558.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 558 after subtracting 1980 from 2538.
Include the next digit (8) from the dividend after 558, then repeat: 5588 / 660

Step 5:
If we divide 5588 by 660, we get 8 and a remainder of 308.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
Subtract 5280 from 5588 to get 308.
Fetch the next digit (1) from the dividend, attach it to 308 and continue: 3081 / 660

On to step 6:
660 can be fit into 3081 4 times, resulting in a remainder of 441.
The next digit of our result is 4. 
Result so far: 384.0
If we subtract 2640 from 3081, we get 441.
Take the next digit (7) from the dividend and append it to 441, then repeat: 4417 / 660

Step 7:
If we divide 4417 by 660, we get 6 and a remainder of 457.
Use 6 as the next digit of our solution. 
Result so far: 3846.0
The remainder is 457 after subtracting 3960 from 4417.
Fetch the next digit (9) from the dividend, attach it to 457 and continue: 4579 / 660

Going ahead to step 8:
When dividing 4579 by 660, we get 6 with a remainder of 619.
Record the quotient 6 as the next digit in the result. 
Result so far: 38466.0
Subtract 3960 from 4579 to get 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

On to step 9:
When dividing 6190 by 660, we get 9 with a remainder of 250.
The next digit of our result is 9. 
Result so far: 38466.9
Subtract 5940 from 6190 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 10:
660 goes into 2500 3 times with a remainder of 520.
The number 3 becomes the next digit in our result. 
Result so far: 38466.93
Subtracting 1980 from 2500 leaves us with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 11:
The number 660 fits into 5200 7 times, leaving a remainder of 580.
Record the quotient 7 as the next digit in the result. 
Result so far: 38466.937
If we take 4620 away from 5200, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Step 12:
The number 660 fits into 5800 8 times, leaving a remainder of 520.
The number 8 becomes the next digit in our result. 
Result so far: 38466.9378
If we take 5280 away from 5800, we end up with 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Advancing to step 13:
The number 660 fits into 5200 7 times, leaving a remainder of 580.
The next digit of our result is 7. 
Result so far: 38466.93787
Subtracting 4620 from 5200 leaves us with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 14:
If we divide 5800 by 660, we get 8 and a remainder of 520.
Write down 8 as next digit of the result. 
Result so far: 38466.937878
The remainder is 520 after subtracting 5280 from 5800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

On to step 15:
If we divide 5200 by 660, we get 7 and a remainder of 580.
The number 7 becomes the next digit in our result. 
Result so far: 38466.9378787
Deduct 4620 from 5200 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Step 16:
660 goes into 5800 8 times with a remainder of 520.
The next digit of our result is 8. 
Result so far: 38466.93787878
Subtract 5280 from 5800 to get 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

In conclusion, the division gives 38466.93787878 with a balance of 5.2e-07.
