Let's divide 880643 by 28
Our goal is to divide 880643 by 28.

On to step 1:
28 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 28

Advancing to step 2:
When dividing 88 by 28, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 84 away from 88, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 28

Let's proceed to step 3:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we take 28 away from 40, we end up with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 28

On to step 4:
28 can be fit into 126 4 times, resulting in a remainder of 14.
The next digit of our result is 4. 
Result so far: 314.0
Subtracting 112 from 126 leaves us with 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 28

Step 5:
28 can be fit into 144 5 times, resulting in a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 3145.0
Subtract 140 from 144 to get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 28

Going ahead to step 6:
43 divided by 28 is 1 with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 31451.0
If we subtract 28 from 43, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
When dividing 150 by 28, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 31451.5
Subtract 140 from 150 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
The number 28 fits into 100 3 times, leaving a remainder of 16.
The next digit of our result is 3. 
Result so far: 31451.53
If we subtract 84 from 100, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 9:
160 divided by 28 is 5 with a remainder of 20.
The next digit of our result is 5. 
Result so far: 31451.535
If we take 140 away from 160, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 31451.5357
If we take 196 away from 200, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 11:
28 goes into 40 1 times with a remainder of 12.
The next digit of our result is 1. 
Result so far: 31451.53571
Subtract 28 from 40 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 31451.535714
Subtract 112 from 120 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 13:
80 divided by 28 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 31451.5357142
If we subtract 56 from 80, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
If we divide 240 by 28, we get 8 and a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 31451.53571428
Subtracting 224 from 240 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 31451.53571428, with a leftover of 1.6e-08.
