We're dividing 55109437 by 209 
Let's see how many times 209 fits into 55109437.

Step 1:
The number 209 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (5) from the dividend, add it to 5, then carry on: 55 / 209

Moving on to step 2:
209 can be fit into 55 0 times, resulting in a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Append the next digit (1) from the dividend to 55 and continue with: 551 / 209

Step 3:
209 goes into 551 2 times with a remainder of 133.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 418 from 551 leaves us with 133.
Include the next digit (0) from the dividend after 133, then repeat: 1330 / 209

Let's proceed to step 4:
If we divide 1330 by 209, we get 6 and a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtract 1254 from 1330 to get 76.
Fetch the next digit (9) from the dividend, attach it to 76 and continue: 769 / 209

Going ahead to step 5:
769 divided by 209 is 3 with a remainder of 142.
Write down 3 as next digit of the result. 
Result so far: 263.0
Deduct 627 from 769 and we're left with 142.
Fetch the next digit (4) from the dividend, attach it to 142 and continue: 1424 / 209

On to step 6:
If we divide 1424 by 209, we get 6 and a remainder of 170.
Put 6 as the next digit of the answer. 
Result so far: 2636.0
Subtracting 1254 from 1424 leaves us with 170.
Fetch the next digit (3) from the dividend, attach it to 170 and continue: 1703 / 209

Step 7:
209 can be fit into 1703 8 times, resulting in a remainder of 31.
Use 8 as the next digit of our solution. 
Result so far: 26368.0
If we subtract 1672 from 1703, we get 31.
Include the next digit (7) from the dividend after 31, then repeat: 317 / 209

Moving on to step 8:
317 divided by 209 is 1 with a remainder of 108.
Put 1 as the next digit of the answer. 
Result so far: 263681.0
If we take 209 away from 317, we end up with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 9:
The number 209 fits into 1080 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 263681.5
Subtracting 1045 from 1080 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 10:
The number 209 fits into 350 1 times, leaving a remainder of 141.
Use 1 as the next digit of our solution. 
Result so far: 263681.51
Subtract 209 from 350 to get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Moving on to step 11:
209 goes into 1410 6 times with a remainder of 156.
Use 6 as the next digit of our solution. 
Result so far: 263681.516
Subtracting 1254 from 1410 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 12:
209 can be fit into 1560 7 times, resulting in a remainder of 97.
The number 7 becomes the next digit in our result. 
Result so far: 263681.5167
Deduct 1463 from 1560 and we're left 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.

Moving on to step 13:
209 can be fit into 970 4 times, resulting in a remainder of 134.
The next digit of our result is 4. 
Result so far: 263681.51674
If we take 836 away from 970, we end up 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.

Let's proceed to step 14:
1340 divided by 209 is 6 with a remainder of 86.
Use 6 as the next digit of our solution. 
Result so far: 263681.516746
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.

Moving on to step 15:
209 goes into 860 4 times with a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 263681.5167464
Subtracting 836 from 860 leaves us 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.

Advancing to step 16:
209 can be fit into 240 1 times, resulting in a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 263681.51674641
If we take 209 away from 240, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

In conclusion, the division gives 263681.51674641 with a balance of 3.1e-08.
