15925811 divided by 665 
We want to divide 15925811 by 665.

Let's proceed to step 1:
665 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 665

On to step 2:
When dividing 15 by 665, we get 0 with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 665

Going ahead to step 3:
The number 665 fits into 159 0 times, leaving a remainder of 159.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 159 leaves us with 159.
Fetch the next digit (2) from the dividend, attach it to 159 and continue: 1592 / 665

Let's proceed to step 4:
If we divide 1592 by 665, we get 2 and a remainder of 262.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 1330 from 1592, we get 262.
Include the next digit (5) from the dividend after 262, then repeat: 2625 / 665

Moving on to step 5:
When dividing 2625 by 665, we get 3 with a remainder of 630.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtracting 1995 from 2625 leaves us with 630.
Bring next digit (8) of the dividend behind the 630 and repeat the process: 6308 / 665

Going ahead to step 6:
If we divide 6308 by 665, we get 9 and a remainder of 323.
The number 9 becomes the next digit in our result. 
Result so far: 239.0
Subtracting 5985 from 6308 leaves us with 323.
Append the next digit (1) from the dividend to 323 and continue with: 3231 / 665

On to step 7:
When dividing 3231 by 665, we get 4 with a remainder of 571.
Put 4 as the next digit of the answer. 
Result so far: 2394.0
The remainder is 571 after subtracting 2660 from 3231.
Bring next digit (1) of the dividend behind the 571 and repeat the process: 5711 / 665

Let's proceed to step 8:
5711 divided by 665 is 8 with a remainder of 391.
The next digit of our result is 8. 
Result so far: 23948.0
If we subtract 5320 from 5711, we get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

On to step 9:
The number 665 fits into 3910 5 times, leaving a remainder of 585.
Put 5 as the next digit of the answer. 
Result so far: 23948.5
The remainder is 585 after subtracting 3325 from 3910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Let's proceed to step 10:
665 can be fit into 5850 8 times, resulting in a remainder of 530.
Put 8 as the next digit of the answer. 
Result so far: 23948.58
If we take 5320 away from 5850, we end up with 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5300, and continue the process.

Step 11:
If we divide 5300 by 665, we get 7 and a remainder of 645.
Write down 7 as next digit of the result. 
Result so far: 23948.587
The remainder is 645 after subtracting 4655 from 5300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6450, and continue the process.

Advancing to step 12:
665 can be fit into 6450 9 times, resulting in a remainder of 465.
Use 9 as the next digit of our solution. 
Result so far: 23948.5879
Subtracting 5985 from 6450 leaves us with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

Advancing to step 13:
665 can be fit into 4650 6 times, resulting in a remainder of 660.
Put 6 as the next digit of the answer. 
Result so far: 23948.58796
The remainder is 660 after subtracting 3990 from 4650.
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 14:
If we divide 6600 by 665, we get 9 and a remainder of 615.
Write down 9 as next digit of the result. 
Result so far: 23948.587969
Subtracting 5985 from 6600 leaves us with 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Let's proceed to step 15:
6150 divided by 665 is 9 with a remainder of 165.
Record the quotient 9 as the next digit in the result. 
Result so far: 23948.5879699
If we take 5985 away from 6150, we end up with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

The final outcome is 23948.5879699, with a leftover of 1.65e-06.
