28123689 ÷ 647 
We want to divide 28123689 by 647.

Moving on to step 1:
If we divide 2 by 647, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 647

Step 2:
647 can be fit into 28 0 times, resulting in a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Grab the next digit (1) from the dividend, add it to 28, then carry on: 281 / 647

Moving on to step 3:
The number 647 fits into 281 0 times, leaving a remainder of 281.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 281, we end up with 281.
Take the next digit (2) from the dividend and append it to 281, then repeat: 2812 / 647

Step 4:
If we divide 2812 by 647, we get 4 and a remainder of 224.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 2588 from 2812 and we're left with 224.
Bring next digit (3) of the dividend behind the 224 and repeat the process: 2243 / 647

Moving on to step 5:
647 can be fit into 2243 3 times, resulting in a remainder of 302.
Use 3 as the next digit of our solution. 
Result so far: 43.0
The remainder is 302 after subtracting 1941 from 2243.
Take the next digit (6) from the dividend and append it to 302, then repeat: 3026 / 647

Step 6:
3026 divided by 647 is 4 with a remainder of 438.
Put 4 as the next digit of the answer. 
Result so far: 434.0
If we take 2588 away from 3026, we end up with 438.
Take the next digit (8) from the dividend and append it to 438, then repeat: 4388 / 647

Step 7:
The number 647 fits into 4388 6 times, leaving a remainder of 506.
Record the quotient 6 as the next digit in the result. 
Result so far: 4346.0
Deduct 3882 from 4388 and we're left with 506.
Fetch the next digit (9) from the dividend, attach it to 506 and continue: 5069 / 647

Let's proceed to step 8:
647 goes into 5069 7 times with a remainder of 540.
Record the quotient 7 as the next digit in the result. 
Result so far: 43467.0
The remainder is 540 after subtracting 4529 from 5069.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

Going ahead to step 9:
The number 647 fits into 5400 8 times, leaving a remainder of 224.
Put 8 as the next digit of the answer. 
Result so far: 43467.8
If we take 5176 away from 5400, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Let's proceed to step 10:
2240 divided by 647 is 3 with a remainder of 299.
The number 3 becomes the next digit in our result. 
Result so far: 43467.83
Subtracting 1941 from 2240 leaves us with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Moving on to step 11:
647 can be fit into 2990 4 times, resulting in a remainder of 402.
Record the quotient 4 as the next digit in the result. 
Result so far: 43467.834
Subtract 2588 from 2990 to get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Going ahead to step 12:
647 goes into 4020 6 times with a remainder of 138.
The number 6 becomes the next digit in our result. 
Result so far: 43467.8346
The remainder is 138 after subtracting 3882 from 4020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 13:
When dividing 1380 by 647, we get 2 with a remainder of 86.
Write down 2 as next digit of the result. 
Result so far: 43467.83462
The remainder is 86 after subtracting 1294 from 1380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Going ahead to step 14:
The number 647 fits into 860 1 times, leaving a remainder of 213.
Record the quotient 1 as the next digit in the result. 
Result so far: 43467.834621
Subtract 647 from 860 to get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Moving on to step 15:
The number 647 fits into 2130 3 times, leaving a remainder of 189.
Use 3 as the next digit of our solution. 
Result so far: 43467.8346213
Deduct 1941 from 2130 and we're left with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

Advancing to step 16:
The number 647 fits into 1890 2 times, leaving a remainder of 596.
The next digit of our result is 2. 
Result so far: 43467.83462132
The remainder is 596 after subtracting 1294 from 1890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

The final result is 43467.83462132 with a remainder of 5.96e-07.
