28824438 ÷ 861 
We want to figure out the number of times 28824438 can be divided by 861.

Step 1:
If we divide 2 by 861, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 861

Moving on to step 2:
When dividing 28 by 861, we get 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 861

Moving on to step 3:
If we divide 288 by 861, we get 0 and a remainder of 288.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 288 leaves us with 288.
Fetch the next digit (2) from the dividend, attach it to 288 and continue: 2882 / 861

Advancing to step 4:
When dividing 2882 by 861, we get 3 with a remainder of 299.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 2583 away from 2882, we end up with 299.
Grab the next digit (4) from the dividend, add it to 299, then carry on: 2994 / 861

Advancing to step 5:
When dividing 2994 by 861, we get 3 with a remainder of 411.
Put 3 as the next digit of the answer. 
Result so far: 33.0
The remainder is 411 after subtracting 2583 from 2994.
Take the next digit (4) from the dividend and append it to 411, then repeat: 4114 / 861

Let's proceed to step 6:
4114 divided by 861 is 4 with a remainder of 670.
Record the quotient 4 as the next digit in the result. 
Result so far: 334.0
Deduct 3444 from 4114 and we're left with 670.
Include the next digit (3) from the dividend after 670, then repeat: 6703 / 861

Advancing to step 7:
861 can be fit into 6703 7 times, resulting in a remainder of 676.
The next digit of our result is 7. 
Result so far: 3347.0
Deduct 6027 from 6703 and we're left with 676.
Bring next digit (8) of the dividend behind the 676 and repeat the process: 6768 / 861

Going ahead to step 8:
861 can be fit into 6768 7 times, resulting in a remainder of 741.
Write down 7 as next digit of the result. 
Result so far: 33477.0
Deduct 6027 from 6768 and we're left with 741.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7410, and continue the process.

Let's proceed to step 9:
If we divide 7410 by 861, we get 8 and a remainder of 522.
The number 8 becomes the next digit in our result. 
Result so far: 33477.8
The remainder is 522 after subtracting 6888 from 7410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Advancing to step 10:
5220 divided by 861 is 6 with a remainder of 54.
Put 6 as the next digit of the answer. 
Result so far: 33477.86
Deduct 5166 from 5220 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 11:
861 can be fit into 540 0 times, resulting in a remainder of 540.
Use 0 as the next digit of our solution. 
Result so far: 33477.86
The remainder is 540 after subtracting 0 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 12:
861 goes into 5400 6 times with a remainder of 234.
Put 6 as the next digit of the answer. 
Result so far: 33477.8606
If we subtract 5166 from 5400, 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.

Step 13:
861 goes into 2340 2 times with a remainder of 618.
Record the quotient 2 as the next digit in the result. 
Result so far: 33477.86062
If we take 1722 away from 2340, we end up with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Going ahead to step 14:
861 goes into 6180 7 times with a remainder of 153.
Use 7 as the next digit of our solution. 
Result so far: 33477.860627
If we subtract 6027 from 6180, we get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

Advancing to step 15:
1530 divided by 861 is 1 with a remainder of 669.
Write down 1 as next digit of the result. 
Result so far: 33477.8606271
Subtract 861 from 1530 to get 669.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6690, and continue the process.

Moving on to step 16:
6690 divided by 861 is 7 with a remainder of 663.
The number 7 becomes the next digit in our result. 
Result so far: 33477.86062717
The remainder is 663 after subtracting 6027 from 6690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6630, and continue the process.

The final outcome is 33477.86062717, with a leftover of 6.63e-07.
