28322603 ÷ 421 
We want to figure out the number of times 28322603 can be divided by 421.

Going ahead to step 1:
421 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 421

Moving on to step 2:
28 divided by 421 is 0 with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Include the next digit (3) from the dividend after 28, then repeat: 283 / 421

Advancing to step 3:
421 can be fit into 283 0 times, resulting in a remainder of 283.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 283 after subtracting 0 from 283.
Include the next digit (2) from the dividend after 283, then repeat: 2832 / 421

Let's proceed to step 4:
2832 divided by 421 is 6 with a remainder of 306.
Use 6 as the next digit of our solution. 
Result so far: 6.0
The remainder is 306 after subtracting 2526 from 2832.
Fetch the next digit (2) from the dividend, attach it to 306 and continue: 3062 / 421

Going ahead to step 5:
If we divide 3062 by 421, we get 7 and a remainder of 115.
The next digit of our result is 7. 
Result so far: 67.0
Deduct 2947 from 3062 and we're left with 115.
Grab the next digit (6) from the dividend, add it to 115, then carry on: 1156 / 421

Moving on to step 6:
If we divide 1156 by 421, we get 2 and a remainder of 314.
Write down 2 as next digit of the result. 
Result so far: 672.0
Deduct 842 from 1156 and we're left with 314.
Include the next digit (0) from the dividend after 314, then repeat: 3140 / 421

Going ahead to step 7:
If we divide 3140 by 421, we get 7 and a remainder of 193.
Put 7 as the next digit of the answer. 
Result so far: 6727.0
The remainder is 193 after subtracting 2947 from 3140.
Include the next digit (3) from the dividend after 193, then repeat: 1933 / 421

Moving on to step 8:
The number 421 fits into 1933 4 times, leaving a remainder of 249.
Write down 4 as next digit of the result. 
Result so far: 67274.0
Subtracting 1684 from 1933 leaves us with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Step 9:
If we divide 2490 by 421, we get 5 and a remainder of 385.
The next digit of our result is 5. 
Result so far: 67274.5
If we subtract 2105 from 2490, we get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Going ahead to step 10:
3850 divided by 421 is 9 with a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 67274.59
If we take 3789 away from 3850, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 11:
When dividing 610 by 421, we get 1 with a remainder of 189.
Use 1 as the next digit of our solution. 
Result so far: 67274.591
Subtract 421 from 610 to get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Going ahead to step 12:
1890 divided by 421 is 4 with a remainder of 206.
Put 4 as the next digit of the answer. 
Result so far: 67274.5914
Subtract 1684 from 1890 to get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Moving on to step 13:
The number 421 fits into 2060 4 times, leaving a remainder of 376.
Put 4 as the next digit of the answer. 
Result so far: 67274.59144
Subtract 1684 from 2060 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

The quotient of the division is 67274.59144, and the remainder is 0.000376.
