We look at the division of 25436206 by 247 
Let's see how many times 247 fits into 25436206.

Step 1:
2 divided by 247 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 247

Moving on to step 2:
25 divided by 247 is 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Grab the next digit (4) from the dividend, add it to 25, then carry on: 254 / 247

On to step 3:
254 divided by 247 is 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 247 away from 254, we end up with 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 247

Moving on to step 4:
247 goes into 73 0 times with a remainder of 73.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 73 leaves us with 73.
Grab the next digit (6) from the dividend, add it to 73, then carry on: 736 / 247

Advancing to step 5:
The number 247 fits into 736 2 times, leaving a remainder of 242.
Use 2 as the next digit of our solution. 
Result so far: 102.0
The remainder is 242 after subtracting 494 from 736.
Include the next digit (2) from the dividend after 242, then repeat: 2422 / 247

Going ahead to step 6:
247 goes into 2422 9 times with a remainder of 199.
The next digit of our result is 9. 
Result so far: 1029.0
Subtracting 2223 from 2422 leaves us with 199.
Grab the next digit (0) from the dividend, add it to 199, then carry on: 1990 / 247

Advancing to step 7:
247 goes into 1990 8 times with a remainder of 14.
The next digit of our result is 8. 
Result so far: 10298.0
Subtract 1976 from 1990 to get 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 247

Let's proceed to step 8:
247 can be fit into 146 0 times, resulting in a remainder of 146.
Record the quotient 0 as the next digit in the result. 
Result so far: 102980.0
Deduct 0 from 146 and we're left with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

Going ahead to step 9:
If we divide 1460 by 247, we get 5 and a remainder of 225.
Put 5 as the next digit of the answer. 
Result so far: 102980.5
The remainder is 225 after subtracting 1235 from 1460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Step 10:
247 goes into 2250 9 times with a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 102980.59
The remainder is 27 after subtracting 2223 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 11:
247 goes into 270 1 times with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 102980.591
If we take 247 away from 270, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 12:
247 goes into 230 0 times with a remainder of 230.
Write down 0 as next digit of the result. 
Result so far: 102980.591
If we take 0 away from 230, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Let's proceed to step 13:
247 goes into 2300 9 times with a remainder of 77.
Write down 9 as next digit of the result. 
Result so far: 102980.59109
Subtracting 2223 from 2300 leaves us with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Going ahead to step 14:
If we divide 770 by 247, we get 3 and a remainder of 29.
Write down 3 as next digit of the result. 
Result so far: 102980.591093
If we subtract 741 from 770, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 15:
290 divided by 247 is 1 with a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 102980.5910931
The remainder is 43 after subtracting 247 from 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 16:
When dividing 430 by 247, we get 1 with a remainder of 183.
Record the quotient 1 as the next digit in the result. 
Result so far: 102980.59109311
Subtracting 247 from 430 leaves us with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

The final outcome is 102980.59109311, with a leftover of 1.83e-07.
