We look at the division of 6418428 by 280 
Let's see how many times 280 fits into 6418428.

Advancing to step 1:
280 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 280

Advancing to step 2:
If we divide 64 by 280, we get 0 and a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Bring next digit (1) of the dividend behind the 64 and repeat the process: 641 / 280

Step 3:
If we divide 641 by 280, we get 2 and a remainder of 81.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 560 from 641, we get 81.
Include the next digit (8) from the dividend after 81, then repeat: 818 / 280

Let's proceed to step 4:
818 divided by 280 is 2 with a remainder of 258.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
Subtract 560 from 818 to get 258.
Fetch the next digit (4) from the dividend, attach it to 258 and continue: 2584 / 280

Step 5:
280 can be fit into 2584 9 times, resulting in a remainder of 64.
The number 9 becomes the next digit in our result. 
Result so far: 229.0
Deduct 2520 from 2584 and we're left with 64.
Append the next digit (2) from the dividend to 64 and continue with: 642 / 280

Let's proceed to step 6:
The number 280 fits into 642 2 times, leaving a remainder of 82.
Write down 2 as next digit of the result. 
Result so far: 2292.0
If we subtract 560 from 642, we get 82.
Include the next digit (8) from the dividend after 82, then repeat: 828 / 280

Moving on to step 7:
280 can be fit into 828 2 times, resulting in a remainder of 268.
The next digit of our result is 2. 
Result so far: 22922.0
Subtracting 560 from 828 leaves us with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 8:
280 can be fit into 2680 9 times, resulting in a remainder of 160.
Put 9 as the next digit of the answer. 
Result so far: 22922.9
Subtract 2520 from 2680 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 9:
When dividing 1600 by 280, we get 5 with a remainder of 200.
Put 5 as the next digit of the answer. 
Result so far: 22922.95
Deduct 1400 from 1600 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 10:
280 can be fit into 2000 7 times, resulting in a remainder of 40.
Put 7 as the next digit of the answer. 
Result so far: 22922.957
Deduct 1960 from 2000 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
280 goes into 400 1 times with a remainder of 120.
Put 1 as the next digit of the answer. 
Result so far: 22922.9571
Deduct 280 from 400 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 12:
If we divide 1200 by 280, we get 4 and a remainder of 80.
Write down 4 as next digit of the result. 
Result so far: 22922.95714
Deduct 1120 from 1200 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 13:
280 goes into 800 2 times with a remainder of 240.
The next digit of our result is 2. 
Result so far: 22922.957142
Subtract 560 from 800 to get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 14:
If we divide 2400 by 280, we get 8 and a remainder of 160.
The number 8 becomes the next digit in our result. 
Result so far: 22922.9571428
If we subtract 2240 from 2400, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 15:
If we divide 1600 by 280, we get 5 and a remainder of 200.
Record the quotient 5 as the next digit in the result. 
Result so far: 22922.95714285
If we subtract 1400 from 1600, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The final result is 22922.95714285 with a remainder of 2e-07.
