We're dividing 55137573 by 809 
We're looking to find how many times 809 goes into 55137573.

Let's proceed to step 1:
If we divide 5 by 809, we get 0 and 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.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 809

Step 2:
55 divided by 809 is 0 with a remainder of 55.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Bring next digit (1) of the dividend behind the 55 and repeat the process: 551 / 809

Going ahead to step 3:
The number 809 fits into 551 0 times, leaving a remainder of 551.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 551 to get 551.
Append the next digit (3) from the dividend to 551 and continue with: 5513 / 809

Step 4:
809 can be fit into 5513 6 times, resulting in a remainder of 659.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 4854 from 5513 and we're left with 659.
Grab the next digit (7) from the dividend, add it to 659, then carry on: 6597 / 809

On to step 5:
The number 809 fits into 6597 8 times, leaving a remainder of 125.
Use 8 as the next digit of our solution. 
Result so far: 68.0
Subtracting 6472 from 6597 leaves us with 125.
Take the next digit (5) from the dividend and append it to 125, then repeat: 1255 / 809

Let's proceed to step 6:
When dividing 1255 by 809, we get 1 with a remainder of 446.
Record the quotient 1 as the next digit in the result. 
Result so far: 681.0
If we take 809 away from 1255, we end up with 446.
Bring next digit (7) of the dividend behind the 446 and repeat the process: 4467 / 809

Moving on to step 7:
When dividing 4467 by 809, we get 5 with a remainder of 422.
Record the quotient 5 as the next digit in the result. 
Result so far: 6815.0
If we subtract 4045 from 4467, we get 422.
Include the next digit (3) from the dividend after 422, then repeat: 4223 / 809

Let's proceed to step 8:
4223 divided by 809 is 5 with a remainder of 178.
Record the quotient 5 as the next digit in the result. 
Result so far: 68155.0
Subtract 4045 from 4223 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Step 9:
809 goes into 1780 2 times with a remainder of 162.
Put 2 as the next digit of the answer. 
Result so far: 68155.2
Subtract 1618 from 1780 to get 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Moving on to step 10:
The number 809 fits into 1620 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 68155.22
If we subtract 1618 from 1620, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 68155.22 with a balance of 0.002.
