We look at the division of 28776373 by 869 
We're looking to find how many times 869 goes into 28776373.

Step 1:
If we divide 2 by 869, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 869

Going ahead to step 2:
869 goes into 28 0 times with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 869

Step 3:
The number 869 fits into 287 0 times, leaving a remainder of 287.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 287 after subtracting 0 from 287.
Append the next digit (7) from the dividend to 287 and continue with: 2877 / 869

Step 4:
2877 divided by 869 is 3 with a remainder of 270.
The next digit of our result is 3. 
Result so far: 3.0
If we take 2607 away from 2877, we end up with 270.
Bring next digit (6) of the dividend behind the 270 and repeat the process: 2706 / 869

Advancing to step 5:
869 can be fit into 2706 3 times, resulting in a remainder of 99.
Put 3 as the next digit of the answer. 
Result so far: 33.0
If we take 2607 away from 2706, we end up with 99.
Grab the next digit (3) from the dividend, add it to 99, then carry on: 993 / 869

Moving on to step 6:
The number 869 fits into 993 1 times, leaving a remainder of 124.
Write down 1 as next digit of the result. 
Result so far: 331.0
Deduct 869 from 993 and we're left with 124.
Append the next digit (7) from the dividend to 124 and continue with: 1247 / 869

Moving on to step 7:
1247 divided by 869 is 1 with a remainder of 378.
The number 1 becomes the next digit in our result. 
Result so far: 3311.0
Subtracting 869 from 1247 leaves us with 378.
Grab the next digit (3) from the dividend, add it to 378, then carry on: 3783 / 869

Step 8:
The number 869 fits into 3783 4 times, leaving a remainder of 307.
Record the quotient 4 as the next digit in the result. 
Result so far: 33114.0
If we take 3476 away from 3783, we end up with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Let's proceed to step 9:
869 can be fit into 3070 3 times, resulting in a remainder of 463.
Use 3 as the next digit of our solution. 
Result so far: 33114.3
If we take 2607 away from 3070, we end up with 463.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

On to step 10:
When dividing 4630 by 869, we get 5 with a remainder of 285.
The next digit of our result is 5. 
Result so far: 33114.35
Subtract 4345 from 4630 to get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Moving on to step 11:
869 can be fit into 2850 3 times, resulting in a remainder of 243.
Write down 3 as next digit of the result. 
Result so far: 33114.353
Subtracting 2607 from 2850 leaves us with 243.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2430, and continue the process.

Going ahead to step 12:
If we divide 2430 by 869, we get 2 and a remainder of 692.
The number 2 becomes the next digit in our result. 
Result so far: 33114.3532
If we subtract 1738 from 2430, we get 692.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6920, and continue the process.

Moving on to step 13:
If we divide 6920 by 869, we get 7 and a remainder of 837.
Write down 7 as next digit of the result. 
Result so far: 33114.35327
Deduct 6083 from 6920 and we're left with 837.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8370, and continue the process.

Moving on to step 14:
869 can be fit into 8370 9 times, resulting in a remainder of 549.
Record the quotient 9 as the next digit in the result. 
Result so far: 33114.353279
Deduct 7821 from 8370 and we're left with 549.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Let's proceed to step 15:
The number 869 fits into 5490 6 times, leaving a remainder of 276.
Record the quotient 6 as the next digit in the result. 
Result so far: 33114.3532796
The remainder is 276 after subtracting 5214 from 5490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

Let's proceed to step 16:
When dividing 2760 by 869, we get 3 with a remainder of 153.
Put 3 as the next digit of the answer. 
Result so far: 33114.35327963
The remainder is 153 after subtracting 2607 from 2760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

The final result is 33114.35327963 with a remainder of 1.53e-07.
