We're dividing 25830379 by 987 
We want to divide 25830379 by 987.

Going ahead to step 1:
987 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 987

Moving on to step 2:
The number 987 fits into 25 0 times, leaving a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Fetch the next digit (8) from the dividend, attach it to 25 and continue: 258 / 987

Advancing to step 3:
When dividing 258 by 987, we get 0 with a remainder of 258.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 258 after subtracting 0 from 258.
Fetch the next digit (3) from the dividend, attach it to 258 and continue: 2583 / 987

Let's proceed to step 4:
2583 divided by 987 is 2 with a remainder of 609.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 1974 away from 2583, we end up with 609.
Fetch the next digit (0) from the dividend, attach it to 609 and continue: 6090 / 987

Let's proceed to step 5:
6090 divided by 987 is 6 with a remainder of 168.
Use 6 as the next digit of our solution. 
Result so far: 26.0
The remainder is 168 after subtracting 5922 from 6090.
Include the next digit (3) from the dividend after 168, then repeat: 1683 / 987

Advancing to step 6:
1683 divided by 987 is 1 with a remainder of 696.
Record the quotient 1 as the next digit in the result. 
Result so far: 261.0
Deduct 987 from 1683 and we're left with 696.
Append the next digit (7) from the dividend to 696 and continue with: 6967 / 987

Advancing to step 7:
6967 divided by 987 is 7 with a remainder of 58.
Write down 7 as next digit of the result. 
Result so far: 2617.0
If we subtract 6909 from 6967, we get 58.
Take the next digit (9) from the dividend and append it to 58, then repeat: 589 / 987

Let's proceed to step 8:
If we divide 589 by 987, we get 0 and a remainder of 589.
Record the quotient 0 as the next digit in the result. 
Result so far: 26170.0
The remainder is 589 after subtracting 0 from 589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Step 9:
When dividing 5890 by 987, we get 5 with a remainder of 955.
Put 5 as the next digit of the answer. 
Result so far: 26170.5
The remainder is 955 after subtracting 4935 from 5890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9550, and continue the process.

Moving on to step 10:
987 can be fit into 9550 9 times, resulting in a remainder of 667.
Record the quotient 9 as the next digit in the result. 
Result so far: 26170.59
Deduct 8883 from 9550 and we're left with 667.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6670, and continue the process.

Going ahead to step 11:
987 goes into 6670 6 times with a remainder of 748.
Use 6 as the next digit of our solution. 
Result so far: 26170.596
Deduct 5922 from 6670 and we're left with 748.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7480, and continue the process.

Moving on to step 12:
987 can be fit into 7480 7 times, resulting in a remainder of 571.
Put 7 as the next digit of the answer. 
Result so far: 26170.5967
If we subtract 6909 from 7480, we get 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Going ahead to step 13:
987 goes into 5710 5 times with a remainder of 775.
Use 5 as the next digit of our solution. 
Result so far: 26170.59675
Deduct 4935 from 5710 and we're left with 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Advancing to step 14:
If we divide 7750 by 987, we get 7 and a remainder of 841.
Write down 7 as next digit of the result. 
Result so far: 26170.596757
If we subtract 6909 from 7750, we get 841.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8410, and continue the process.

Moving on to step 15:
987 goes into 8410 8 times with a remainder of 514.
Use 8 as the next digit of our solution. 
Result so far: 26170.5967578
Subtract 7896 from 8410 to get 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Step 16:
The number 987 fits into 5140 5 times, leaving a remainder of 205.
Put 5 as the next digit of the answer. 
Result so far: 26170.59675785
Subtract 4935 from 5140 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

The quotient of the division is 26170.59675785, and the remainder is 2.05e-07.
