We look at the division of 12443335 by 869 
We want to divide 12443335 by 869.

Going ahead to step 1:
The number 869 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 869

Going ahead to step 2:
869 can be fit into 12 0 times, resulting in a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 869

Let's proceed to step 3:
869 goes into 124 0 times with a remainder of 124.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 124, we end up with 124.
Include the next digit (4) from the dividend after 124, then repeat: 1244 / 869

Step 4:
869 goes into 1244 1 times with a remainder of 375.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 869 from 1244 and we're left with 375.
Fetch the next digit (3) from the dividend, attach it to 375 and continue: 3753 / 869

Moving on to step 5:
The number 869 fits into 3753 4 times, leaving a remainder of 277.
The next digit of our result is 4. 
Result so far: 14.0
If we take 3476 away from 3753, we end up with 277.
Bring next digit (3) of the dividend behind the 277 and repeat the process: 2773 / 869

Advancing to step 6:
If we divide 2773 by 869, we get 3 and a remainder of 166.
Write down 3 as next digit of the result. 
Result so far: 143.0
Subtract 2607 from 2773 to get 166.
Take the next digit (3) from the dividend and append it to 166, then repeat: 1663 / 869

Let's proceed to step 7:
If we divide 1663 by 869, we get 1 and a remainder of 794.
Record the quotient 1 as the next digit in the result. 
Result so far: 1431.0
Subtract 869 from 1663 to get 794.
Include the next digit (5) from the dividend after 794, then repeat: 7945 / 869

Going ahead to step 8:
If we divide 7945 by 869, we get 9 and a remainder of 124.
The next digit of our result is 9. 
Result so far: 14319.0
Deduct 7821 from 7945 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 9:
1240 divided by 869 is 1 with a remainder of 371.
The number 1 becomes the next digit in our result. 
Result so far: 14319.1
Deduct 869 from 1240 and we're left with 371.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Let's proceed to step 10:
If we divide 3710 by 869, we get 4 and a remainder of 234.
Use 4 as the next digit of our solution. 
Result so far: 14319.14
If we subtract 3476 from 3710, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 11:
The number 869 fits into 2340 2 times, leaving a remainder of 602.
The next digit of our result is 2. 
Result so far: 14319.142
Subtract 1738 from 2340 to get 602.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6020, and continue the process.

Advancing to step 12:
869 can be fit into 6020 6 times, resulting in a remainder of 806.
The next digit of our result is 6. 
Result so far: 14319.1426
If we subtract 5214 from 6020, we get 806.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8060, and continue the process.

Going ahead to step 13:
The number 869 fits into 8060 9 times, leaving a remainder of 239.
The next digit of our result is 9. 
Result so far: 14319.14269
If we subtract 7821 from 8060, we get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Going ahead to step 14:
The number 869 fits into 2390 2 times, leaving a remainder of 652.
Write down 2 as next digit of the result. 
Result so far: 14319.142692
Subtracting 1738 from 2390 leaves us with 652.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6520, and continue the process.

Moving on to step 15:
6520 divided by 869 is 7 with a remainder of 437.
The number 7 becomes the next digit in our result. 
Result so far: 14319.1426927
If we take 6083 away from 6520, we end up with 437.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4370, and continue the process.

Step 16:
The number 869 fits into 4370 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 14319.14269275
The remainder is 25 after subtracting 4345 from 4370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 14319.14269275, and the remainder is 2.5e-08.
