Let's divide 432221 by 28
We want to figure out the number of times 432221 can be divided by 28.

Let's proceed to step 1:
28 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 28

Advancing to step 2:
When dividing 43 by 28, we get 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 15 after subtracting 28 from 43.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 28

Step 3:
When dividing 152 by 28, we get 5 with a remainder of 12.
Use 5 as the next digit of our solution. 
Result so far: 15.0
The remainder is 12 after subtracting 140 from 152.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 28

Let's proceed to step 4:
28 goes into 122 4 times with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 154.0
If we subtract 112 from 122, we get 10.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 28

Advancing to step 5:
28 can be fit into 102 3 times, resulting in a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 1543.0
Subtracting 84 from 102 leaves us with 18.
Include the next digit (1) from the dividend after 18, then repeat: 181 / 28

Moving on to step 6:
The number 28 fits into 181 6 times, leaving a remainder of 13.
Record the quotient 6 as the next digit in the result. 
Result so far: 15436.0
If we take 168 away from 181, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
The number 28 fits into 130 4 times, leaving a remainder of 18.
The next digit of our result is 4. 
Result so far: 15436.4
If we subtract 112 from 130, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 8:
28 can be fit into 180 6 times, resulting in a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 15436.46
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
28 can be fit into 120 4 times, resulting in a remainder of 8.
The next digit of our result is 4. 
Result so far: 15436.464
Subtracting 112 from 120 leaves us 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.

Step 10:
If we divide 80 by 28, we get 2 and a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 15436.4642
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.

Going ahead to step 11:
28 can be fit into 240 8 times, resulting in a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 15436.46428
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 12:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 15436.464285
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.

Going ahead to step 13:
200 divided by 28 is 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 15436.4642857
Subtracting 196 from 200 leaves us 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 14:
When dividing 40 by 28, we get 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 15436.46428571
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.

Our division results in 15436.46428571 with a remaining 1.2e-08.
