We look at the division of 54952287 by 839 
We want to divide 54952287 by 839.

Going ahead to step 1:
When dividing 5 by 839, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 839

Moving on to step 2:
When dividing 54 by 839, we get 0 with a remainder of 54.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 54 leaves us with 54.
Append the next digit (9) from the dividend to 54 and continue with: 549 / 839

Going ahead to step 3:
If we divide 549 by 839, we get 0 and a remainder of 549.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 549 leaves us with 549.
Include the next digit (5) from the dividend after 549, then repeat: 5495 / 839

Moving on to step 4:
5495 divided by 839 is 6 with a remainder of 461.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 5034 away from 5495, we end up with 461.
Take the next digit (2) from the dividend and append it to 461, then repeat: 4612 / 839

Step 5:
839 can be fit into 4612 5 times, resulting in a remainder of 417.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
Subtract 4195 from 4612 to get 417.
Include the next digit (2) from the dividend after 417, then repeat: 4172 / 839

Step 6:
4172 divided by 839 is 4 with a remainder of 816.
Put 4 as the next digit of the answer. 
Result so far: 654.0
The remainder is 816 after subtracting 3356 from 4172.
Grab the next digit (8) from the dividend, add it to 816, then carry on: 8168 / 839

Advancing to step 7:
If we divide 8168 by 839, we get 9 and a remainder of 617.
Write down 9 as next digit of the result. 
Result so far: 6549.0
Subtract 7551 from 8168 to get 617.
Bring next digit (7) of the dividend behind the 617 and repeat the process: 6177 / 839

Step 8:
The number 839 fits into 6177 7 times, leaving a remainder of 304.
Record the quotient 7 as the next digit in the result. 
Result so far: 65497.0
Deduct 5873 from 6177 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Advancing to step 9:
839 can be fit into 3040 3 times, resulting in a remainder of 523.
Write down 3 as next digit of the result. 
Result so far: 65497.3
The remainder is 523 after subtracting 2517 from 3040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Let's proceed to step 10:
The number 839 fits into 5230 6 times, leaving a remainder of 196.
Write down 6 as next digit of the result. 
Result so far: 65497.36
Subtract 5034 from 5230 to get 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 11:
The number 839 fits into 1960 2 times, leaving a remainder of 282.
The number 2 becomes the next digit in our result. 
Result so far: 65497.362
If we take 1678 away from 1960, we end up with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Going ahead to step 12:
If we divide 2820 by 839, we get 3 and a remainder of 303.
The next digit of our result is 3. 
Result so far: 65497.3623
The remainder is 303 after subtracting 2517 from 2820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Going ahead to step 13:
The number 839 fits into 3030 3 times, leaving a remainder of 513.
Use 3 as the next digit of our solution. 
Result so far: 65497.36233
Deduct 2517 from 3030 and we're left with 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

The final outcome is 65497.36233, with a leftover of 0.000513.
