461638 ÷ 28 
We're looking to find how many times 28 goes into 461638.

Moving on to step 1:
4 divided by 28 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 28

Advancing to step 2:
If we divide 46 by 28, we get 1 and a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 28 away from 46, we end up with 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 28

Moving on to step 3:
When dividing 181 by 28, we get 6 with a remainder of 13.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtract 168 from 181 to get 13.
Fetch the next digit (6) from the dividend, attach it to 13 and continue: 136 / 28

Going ahead to step 4:
28 goes into 136 4 times with a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 164.0
If we take 112 away from 136, we end up with 24.
Fetch the next digit (3) from the dividend, attach it to 24 and continue: 243 / 28

Advancing to step 5:
The number 28 fits into 243 8 times, leaving a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 1648.0
If we take 224 away from 243, we end up with 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 28

Moving on to step 6:
28 can be fit into 198 7 times, resulting in a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 16487.0
Deduct 196 from 198 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
When dividing 20 by 28, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 16487.0
Subtract 0 from 20 to get 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 8:
When dividing 200 by 28, we get 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 16487.07
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.

Advancing to step 9:
The number 28 fits into 40 1 times, leaving a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 16487.071
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.

Step 10:
120 divided by 28 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 16487.0714
The remainder is 8 after subtracting 112 from 120.
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 11:
80 divided by 28 is 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 16487.07142
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.

Moving on to step 12:
The number 28 fits into 240 8 times, leaving a remainder of 16.
The next digit of our result is 8. 
Result so far: 16487.071428
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.

Moving on to 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: 16487.0714285
If we subtract 140 from 160, we get 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:
The number 28 fits into 200 7 times, leaving a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 16487.07142857
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.

After the division, we end up with 16487.07142857 and a remainder of 4e-09.
