We're dividing 25212185 by 209 
Let's see how many times 209 fits into 25212185.

Advancing to step 1:
The number 209 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 209

Advancing to step 2:
The number 209 fits into 25 0 times, leaving a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Grab the next digit (2) from the dividend, add it to 25, then carry on: 252 / 209

On to step 3:
209 can be fit into 252 1 times, resulting in a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 209 away from 252, we end up with 43.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 209

Step 4:
209 can be fit into 431 2 times, resulting in a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 13 after subtracting 418 from 431.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 209

Step 5:
When dividing 132 by 209, we get 0 with a remainder of 132.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
Subtract 0 from 132 to get 132.
Append the next digit (1) from the dividend to 132 and continue with: 1321 / 209

On to step 6:
When dividing 1321 by 209, we get 6 with a remainder of 67.
Put 6 as the next digit of the answer. 
Result so far: 1206.0
Subtracting 1254 from 1321 leaves us with 67.
Bring next digit (8) of the dividend behind the 67 and repeat the process: 678 / 209

Advancing to step 7:
209 can be fit into 678 3 times, resulting in a remainder of 51.
The number 3 becomes the next digit in our result. 
Result so far: 12063.0
Deduct 627 from 678 and we're left with 51.
Include the next digit (5) from the dividend after 51, then repeat: 515 / 209

Moving on to step 8:
If we divide 515 by 209, we get 2 and a remainder of 97.
Record the quotient 2 as the next digit in the result. 
Result so far: 120632.0
If we take 418 away from 515, we end up with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Step 9:
If we divide 970 by 209, we get 4 and a remainder of 134.
Write down 4 as next digit of the result. 
Result so far: 120632.4
Subtracting 836 from 970 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

On to step 10:
The number 209 fits into 1340 6 times, leaving a remainder of 86.
Write down 6 as next digit of the result. 
Result so far: 120632.46
If we subtract 1254 from 1340, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 11:
209 can be fit into 860 4 times, resulting in a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 120632.464
Deduct 836 from 860 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 12:
209 can be fit into 240 1 times, resulting in a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 120632.4641
The remainder is 31 after subtracting 209 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 13:
When dividing 310 by 209, we get 1 with a remainder of 101.
Write down 1 as next digit of the result. 
Result so far: 120632.46411
Subtract 209 from 310 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Our division results in 120632.46411 with a remaining 0.000101.
