Let's divide 646102 by 28
We want to divide 646102 by 28.

Advancing to step 1:
When dividing 6 by 28, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 28

Going ahead to step 2:
If we divide 64 by 28, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 56 from 64 and we're left with 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 28

Let's proceed to step 3:
When dividing 86 by 28, we get 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 23.0
Deduct 84 from 86 and we're left with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 28

On to step 4:
21 divided by 28 is 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 230.0
If we take 0 away from 21, we end up with 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 28

On to step 5:
When dividing 210 by 28, we get 7 with a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 2307.0
The remainder is 14 after subtracting 196 from 210.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 28

Step 6:
28 can be fit into 142 5 times, resulting in a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 23075.0
If we subtract 140 from 142, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
When dividing 20 by 28, we get 0 with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 23075.0
If we take 0 away from 20, 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.

Advancing to step 8:
200 divided by 28 is 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 23075.07
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.

Going ahead to step 9:
28 goes into 40 1 times with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 23075.071
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.

Let's proceed to step 10:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 23075.0714
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.

Step 11:
When dividing 80 by 28, we get 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 23075.07142
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.

Moving on to step 12:
If we divide 240 by 28, we get 8 and a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 23075.071428
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.

Step 13:
160 divided by 28 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 23075.0714285
Deduct 140 from 160 and we're left 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 14:
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: 23075.07142857
The remainder is 4 after subtracting 196 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 23075.07142857, and the remainder is 4e-09.
