We look at the division of 52585605 by 209 
We want to figure out the number of times 52585605 can be divided by 209.

Going ahead to step 1:
The number 209 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 209

Moving on to step 2:
The number 209 fits into 52 0 times, leaving a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Append the next digit (5) from the dividend to 52 and continue with: 525 / 209

Step 3:
209 can be fit into 525 2 times, resulting in a remainder of 107.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 418 from 525, we get 107.
Include the next digit (8) from the dividend after 107, then repeat: 1078 / 209

Advancing to step 4:
1078 divided by 209 is 5 with a remainder of 33.
The next digit of our result is 5. 
Result so far: 25.0
Subtract 1045 from 1078 to get 33.
Grab the next digit (5) from the dividend, add it to 33, then carry on: 335 / 209

Let's proceed to step 5:
335 divided by 209 is 1 with a remainder of 126.
The number 1 becomes the next digit in our result. 
Result so far: 251.0
The remainder is 126 after subtracting 209 from 335.
Append the next digit (6) from the dividend to 126 and continue with: 1266 / 209

Step 6:
If we divide 1266 by 209, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 2516.0
If we take 1254 away from 1266, we end up with 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 209

Going ahead to step 7:
209 can be fit into 120 0 times, resulting in a remainder of 120.
The next digit of our result is 0. 
Result so far: 25160.0
The remainder is 120 after subtracting 0 from 120.
Bring next digit (5) of the dividend behind the 120 and repeat the process: 1205 / 209

Advancing to step 8:
When dividing 1205 by 209, we get 5 with a remainder of 160.
Write down 5 as next digit of the result. 
Result so far: 251605.0
Subtract 1045 from 1205 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 9:
The number 209 fits into 1600 7 times, leaving a remainder of 137.
Use 7 as the next digit of our solution. 
Result so far: 251605.7
Subtracting 1463 from 1600 leaves us with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 10:
If we divide 1370 by 209, we get 6 and a remainder of 116.
Put 6 as the next digit of the answer. 
Result so far: 251605.76
Deduct 1254 from 1370 and we're left with 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Step 11:
1160 divided by 209 is 5 with a remainder of 115.
Use 5 as the next digit of our solution. 
Result so far: 251605.765
Subtract 1045 from 1160 to get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Let's proceed to step 12:
The number 209 fits into 1150 5 times, leaving a remainder of 105.
Put 5 as the next digit of the answer. 
Result so far: 251605.7655
Subtracting 1045 from 1150 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

After the division, we end up with 251605.7655 and a remainder of 0.00105.
