27815021 divided by 649 
Our goal is to divide 27815021 by 649.

Let's proceed to step 1:
649 can be fit into 2 0 times, resulting in 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.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 649

Going ahead to step 2:
The number 649 fits into 27 0 times, leaving a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 27 after subtracting 0 from 27.
Grab the next digit (8) from the dividend, add it to 27, then carry on: 278 / 649

On to step 3:
649 goes into 278 0 times with a remainder of 278.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 278 and we're left with 278.
Append the next digit (1) from the dividend to 278 and continue with: 2781 / 649

Let's proceed to step 4:
When dividing 2781 by 649, we get 4 with a remainder of 185.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtract 2596 from 2781 to get 185.
Append the next digit (5) from the dividend to 185 and continue with: 1855 / 649

Advancing to step 5:
When dividing 1855 by 649, we get 2 with a remainder of 557.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
The remainder is 557 after subtracting 1298 from 1855.
Bring next digit (0) of the dividend behind the 557 and repeat the process: 5570 / 649

Moving on to step 6:
5570 divided by 649 is 8 with a remainder of 378.
The number 8 becomes the next digit in our result. 
Result so far: 428.0
If we subtract 5192 from 5570, we get 378.
Take the next digit (2) from the dividend and append it to 378, then repeat: 3782 / 649

On to step 7:
649 can be fit into 3782 5 times, resulting in a remainder of 537.
Put 5 as the next digit of the answer. 
Result so far: 4285.0
If we take 3245 away from 3782, we end up with 537.
Fetch the next digit (1) from the dividend, attach it to 537 and continue: 5371 / 649

Going ahead to step 8:
If we divide 5371 by 649, we get 8 and a remainder of 179.
Use 8 as the next digit of our solution. 
Result so far: 42858.0
If we take 5192 away from 5371, we end up with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Going ahead to step 9:
When dividing 1790 by 649, we get 2 with a remainder of 492.
Write down 2 as next digit of the result. 
Result so far: 42858.2
If we subtract 1298 from 1790, we get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Let's proceed to step 10:
When dividing 4920 by 649, we get 7 with a remainder of 377.
Record the quotient 7 as the next digit in the result. 
Result so far: 42858.27
Subtract 4543 from 4920 to get 377.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3770, and continue the process.

Going ahead to step 11:
The number 649 fits into 3770 5 times, leaving a remainder of 525.
The next digit of our result is 5. 
Result so far: 42858.275
Deduct 3245 from 3770 and we're left with 525.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5250, and continue the process.

Going ahead to step 12:
649 can be fit into 5250 8 times, resulting in a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 42858.2758
If we take 5192 away from 5250, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 13:
If we divide 580 by 649, we get 0 and a remainder of 580.
Put 0 as the next digit of the answer. 
Result so far: 42858.2758
Deduct 0 from 580 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Step 14:
When dividing 5800 by 649, we get 8 with a remainder of 608.
Write down 8 as next digit of the result. 
Result so far: 42858.275808
If we subtract 5192 from 5800, we get 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Moving on to step 15:
If we divide 6080 by 649, we get 9 and a remainder of 239.
The number 9 becomes the next digit in our result. 
Result so far: 42858.2758089
If we subtract 5841 from 6080, we get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Moving on to step 16:
2390 divided by 649 is 3 with a remainder of 443.
Use 3 as the next digit of our solution. 
Result so far: 42858.27580893
Subtracting 1947 from 2390 leaves us with 443.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4430, and continue the process.

After the division, we end up with 42858.27580893 and a remainder of 4.43e-07.
