We look at the division of 25638355 by 949 
We want to divide 25638355 by 949.

Moving on to step 1:
949 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 949

Advancing to step 2:
When dividing 25 by 949, we get 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Take the next digit (6) from the dividend and append it to 25, then repeat: 256 / 949

On to step 3:
If we divide 256 by 949, we get 0 and a remainder of 256.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 256 leaves us with 256.
Fetch the next digit (3) from the dividend, attach it to 256 and continue: 2563 / 949

On to step 4:
949 goes into 2563 2 times with a remainder of 665.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1898 from 2563 and we're left with 665.
Include the next digit (8) from the dividend after 665, then repeat: 6658 / 949

Step 5:
The number 949 fits into 6658 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we take 6643 away from 6658, we end up with 15.
Take the next digit (3) from the dividend and append it to 15, then repeat: 153 / 949

Going ahead to step 6:
The number 949 fits into 153 0 times, leaving a remainder of 153.
The next digit of our result is 0. 
Result so far: 270.0
The remainder is 153 after subtracting 0 from 153.
Take the next digit (5) from the dividend and append it to 153, then repeat: 1535 / 949

Step 7:
If we divide 1535 by 949, we get 1 and a remainder of 586.
The next digit of our result is 1. 
Result so far: 2701.0
If we take 949 away from 1535, we end up with 586.
Take the next digit (5) from the dividend and append it to 586, then repeat: 5865 / 949

Let's proceed to step 8:
949 can be fit into 5865 6 times, resulting in a remainder of 171.
Write down 6 as next digit of the result. 
Result so far: 27016.0
If we take 5694 away from 5865, we end up with 171.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1710, and continue the process.

Advancing to step 9:
When dividing 1710 by 949, we get 1 with a remainder of 761.
Record the quotient 1 as the next digit in the result. 
Result so far: 27016.1
If we subtract 949 from 1710, we get 761.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7610, and continue the process.

On to step 10:
7610 divided by 949 is 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 27016.18
The remainder is 18 after subtracting 7592 from 7610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
180 divided by 949 is 0 with a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 27016.18
If we subtract 0 from 180, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Going ahead to step 12:
When dividing 1800 by 949, we get 1 with a remainder of 851.
Use 1 as the next digit of our solution. 
Result so far: 27016.1801
Subtract 949 from 1800 to get 851.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8510, and continue the process.

Going ahead to step 13:
949 goes into 8510 8 times with a remainder of 918.
Write down 8 as next digit of the result. 
Result so far: 27016.18018
Deduct 7592 from 8510 and we're left with 918.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9180, and continue the process.

Moving on to step 14:
The number 949 fits into 9180 9 times, leaving a remainder of 639.
The next digit of our result is 9. 
Result so far: 27016.180189
If we take 8541 away from 9180, we end up with 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6390, and continue the process.

Step 15:
6390 divided by 949 is 6 with a remainder of 696.
Put 6 as the next digit of the answer. 
Result so far: 27016.1801896
If we subtract 5694 from 6390, we get 696.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

Advancing to step 16:
6960 divided by 949 is 7 with a remainder of 317.
The number 7 becomes the next digit in our result. 
Result so far: 27016.18018967
Subtracting 6643 from 6960 leaves us with 317.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3170, and continue the process.

The final outcome is 27016.18018967, with a leftover of 3.17e-07.
