Let's divide 12451899 by 271
We want to divide 12451899 by 271.

Step 1:
1 divided by 271 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 271

Going ahead to step 2:
271 can be fit into 12 0 times, resulting in a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 271

Advancing to step 3:
The number 271 fits into 124 0 times, leaving a remainder of 124.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 124 and we're left with 124.
Take the next digit (5) from the dividend and append it to 124, then repeat: 1245 / 271

Going ahead to step 4:
If we divide 1245 by 271, we get 4 and a remainder of 161.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 1084 from 1245, we get 161.
Include the next digit (1) from the dividend after 161, then repeat: 1611 / 271

On to step 5:
The number 271 fits into 1611 5 times, leaving a remainder of 256.
Use 5 as the next digit of our solution. 
Result so far: 45.0
The remainder is 256 after subtracting 1355 from 1611.
Include the next digit (8) from the dividend after 256, then repeat: 2568 / 271

Let's proceed to step 6:
When dividing 2568 by 271, we get 9 with a remainder of 129.
Record the quotient 9 as the next digit in the result. 
Result so far: 459.0
Subtracting 2439 from 2568 leaves us with 129.
Bring next digit (9) of the dividend behind the 129 and repeat the process: 1299 / 271

On to step 7:
When dividing 1299 by 271, we get 4 with a remainder of 215.
The number 4 becomes the next digit in our result. 
Result so far: 4594.0
Subtract 1084 from 1299 to get 215.
Fetch the next digit (9) from the dividend, attach it to 215 and continue: 2159 / 271

Advancing to step 8:
271 can be fit into 2159 7 times, resulting in a remainder of 262.
The number 7 becomes the next digit in our result. 
Result so far: 45947.0
Deduct 1897 from 2159 and we're left with 262.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2620, and continue the process.

Step 9:
271 can be fit into 2620 9 times, resulting in a remainder of 181.
Record the quotient 9 as the next digit in the result. 
Result so far: 45947.9
If we subtract 2439 from 2620, we get 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Going ahead to step 10:
If we divide 1810 by 271, we get 6 and a remainder of 184.
The next digit of our result is 6. 
Result so far: 45947.96
If we subtract 1626 from 1810, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Advancing to step 11:
271 can be fit into 1840 6 times, resulting in a remainder of 214.
Put 6 as the next digit of the answer. 
Result so far: 45947.966
If we subtract 1626 from 1840, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

The final result is 45947.966 with a remainder of 0.0214.
