180451 ÷ 28 
We want to figure out the number of times 180451 can be divided by 28.

Let's proceed to step 1:
When dividing 1 by 28, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 28

On to step 2:
18 divided by 28 is 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 28

Going ahead to step 3:
The number 28 fits into 180 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 12 after subtracting 168 from 180.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 28

On to step 4:
28 goes into 124 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 64.0
Subtracting 112 from 124 leaves us with 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 28

Let's proceed to step 5:
If we divide 125 by 28, we get 4 and a remainder of 13.
The next digit of our result is 4. 
Result so far: 644.0
If we take 112 away from 125, we end up with 13.
Grab the next digit (1) from the dividend, add it to 13, then carry on: 131 / 28

Moving on to step 6:
28 can be fit into 131 4 times, resulting in a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 6444.0
If we subtract 112 from 131, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
28 can be fit into 190 6 times, resulting in a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 6444.6
If we subtract 168 from 190, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
If we divide 220 by 28, we get 7 and a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 6444.67
Subtracting 196 from 220 leaves us 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.

Let's proceed to step 9:
240 divided by 28 is 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 6444.678
If we take 224 away from 240, we end up 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.

Advancing to step 10:
160 divided by 28 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 6444.6785
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.

Step 11:
When dividing 200 by 28, we get 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 6444.67857
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.

Step 12:
When dividing 40 by 28, we get 1 with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 6444.678571
If we subtract 28 from 40, we 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.

Going ahead to step 13:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 6444.6785714
If we subtract 112 from 120, we 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.

Going ahead to step 14:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 6444.67857142
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 6444.67857142 and a remainder of 2.4e-08.
