18213432 divided by 28 
Let's see how many times 28 fits into 18213432.

Step 1:
If we divide 1 by 28, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 28

Going ahead to step 2:
28 goes into 18 0 times with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 28

On to step 3:
28 can be fit into 182 6 times, resulting in a remainder of 14.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 168 from 182 leaves us with 14.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 28

Advancing to step 4:
The number 28 fits into 141 5 times, leaving a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
Subtracting 140 from 141 leaves us with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 28

Let's proceed to step 5:
13 divided by 28 is 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 650.0
If we subtract 0 from 13, we get 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 28

Advancing to step 6:
When dividing 134 by 28, we get 4 with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 6504.0
Deduct 112 from 134 and we're left with 22.
Take the next digit (3) from the dividend and append it to 22, then repeat: 223 / 28

Going ahead to step 7:
223 divided by 28 is 7 with a remainder of 27.
The next digit of our result is 7. 
Result so far: 65047.0
Deduct 196 from 223 and we're left with 27.
Fetch the next digit (2) from the dividend, attach it to 27 and continue: 272 / 28

Let's proceed to step 8:
The number 28 fits into 272 9 times, leaving a remainder of 20.
The next digit of our result is 9. 
Result so far: 650479.0
If we take 252 away from 272, 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.

Moving on to step 9:
If we divide 200 by 28, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 650479.7
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 10:
If we divide 40 by 28, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 650479.71
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.

Going ahead to step 11:
When dividing 120 by 28, we get 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 650479.714
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.

Advancing to step 12:
The number 28 fits into 80 2 times, leaving a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 650479.7142
If we take 56 away from 80, we end up 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.

On to step 13:
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: 650479.71428
If we subtract 224 from 240, 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.

Let's proceed to step 14:
When dividing 160 by 28, we get 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 650479.714285
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 15:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 650479.7142857
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.

On to step 16:
40 divided by 28 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 650479.71428571
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 650479.71428571 and a remainder of 1.2e-08.
