We're dividing 27149778 by 210 
We want to divide 27149778 by 210.

Step 1:
When dividing 2 by 210, we get 0 with 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.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 210

Let's proceed to step 2:
27 divided by 210 is 0 with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 27 to get 27.
Grab the next digit (1) from the dividend, add it to 27, then carry on: 271 / 210

Moving on to step 3:
271 divided by 210 is 1 with a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 210 from 271, we get 61.
Append the next digit (4) from the dividend to 61 and continue with: 614 / 210

Step 4:
614 divided by 210 is 2 with a remainder of 194.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 420 from 614 to get 194.
Take the next digit (9) from the dividend and append it to 194, then repeat: 1949 / 210

On to step 5:
210 goes into 1949 9 times with a remainder of 59.
Use 9 as the next digit of our solution. 
Result so far: 129.0
If we subtract 1890 from 1949, we get 59.
Include the next digit (7) from the dividend after 59, then repeat: 597 / 210

Going ahead to step 6:
If we divide 597 by 210, we get 2 and a remainder of 177.
Use 2 as the next digit of our solution. 
Result so far: 1292.0
Deduct 420 from 597 and we're left with 177.
Include the next digit (7) from the dividend after 177, then repeat: 1777 / 210

On to step 7:
The number 210 fits into 1777 8 times, leaving a remainder of 97.
Record the quotient 8 as the next digit in the result. 
Result so far: 12928.0
If we subtract 1680 from 1777, we get 97.
Append the next digit (8) from the dividend to 97 and continue with: 978 / 210

Let's proceed to step 8:
When dividing 978 by 210, we get 4 with a remainder of 138.
The next digit of our result is 4. 
Result so far: 129284.0
Subtracting 840 from 978 leaves us with 138.
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 9:
When dividing 1380 by 210, we get 6 with a remainder of 120.
Use 6 as the next digit of our solution. 
Result so far: 129284.6
Subtract 1260 from 1380 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 10:
210 goes into 1200 5 times with a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 129284.65
Deduct 1050 from 1200 and we're left with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

On to step 11:
210 can be fit into 1500 7 times, resulting in a remainder of 30.
Put 7 as the next digit of the answer. 
Result so far: 129284.657
The remainder is 30 after subtracting 1470 from 1500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 12:
210 can be fit into 300 1 times, resulting in a remainder of 90.
Put 1 as the next digit of the answer. 
Result so far: 129284.6571
Deduct 210 from 300 and we're left with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 13:
If we divide 900 by 210, we get 4 and a remainder of 60.
Record the quotient 4 as the next digit in the result. 
Result so far: 129284.65714
The remainder is 60 after subtracting 840 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 14:
If we divide 600 by 210, we get 2 and a remainder of 180.
The number 2 becomes the next digit in our result. 
Result so far: 129284.657142
The remainder is 180 after subtracting 420 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 15:
1800 divided by 210 is 8 with a remainder of 120.
The number 8 becomes the next digit in our result. 
Result so far: 129284.6571428
Subtracting 1680 from 1800 leaves us 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.

Moving on to step 16:
1200 divided by 210 is 5 with a remainder of 150.
The number 5 becomes the next digit in our result. 
Result so far: 129284.65714285
If we take 1050 away from 1200, we end up with 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

After the division, we end up with 129284.65714285 and a remainder of 1.5e-07.
