Let's divide 72981365 by 28
We want to figure out the number of times 72981365 can be divided by 28.

On to step 1:
The number 28 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 28

On to step 2:
28 goes into 72 2 times with a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 56 away from 72, we end up with 16.
Append the next digit (9) from the dividend to 16 and continue with: 169 / 28

Going ahead to step 3:
The number 28 fits into 169 6 times, leaving a remainder of 1.
The next digit of our result is 6. 
Result so far: 26.0
Subtracting 168 from 169 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 28

Let's proceed to step 4:
When dividing 18 by 28, we get 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 260.0
Subtracting 0 from 18 leaves us with 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 28

On to step 5:
28 goes into 181 6 times with a remainder of 13.
Write down 6 as next digit of the result. 
Result so far: 2606.0
If we take 168 away from 181, we end up with 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 28

Moving on to step 6:
133 divided by 28 is 4 with a remainder of 21.
The next digit of our result is 4. 
Result so far: 26064.0
If we take 112 away from 133, we end up with 21.
Grab the next digit (6) from the dividend, add it to 21, then carry on: 216 / 28

Moving on to step 7:
216 divided by 28 is 7 with a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 260647.0
Deduct 196 from 216 and we're left with 20.
Fetch the next digit (5) from the dividend, attach it to 20 and continue: 205 / 28

Advancing to step 8:
When dividing 205 by 28, we get 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 2606477.0
The remainder is 9 after subtracting 196 from 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
90 divided by 28 is 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 2606477.3
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
28 can be fit into 60 2 times, resulting in a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 2606477.32
If we subtract 56 from 60, we get 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:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 2606477.321
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.

On to step 12:
When dividing 120 by 28, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 2606477.3214
If we take 112 away from 120, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
80 divided by 28 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 2606477.32142
Deduct 56 from 80 and we're left with 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: 2606477.321428
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 15:
If we divide 160 by 28, we get 5 and a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 2606477.3214285
The remainder is 20 after subtracting 140 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 16:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 2606477.32142857
Deduct 196 from 200 and we're left 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.

After the division, we end up with 2606477.32142857 and a remainder of 4e-09.
