We look at the division of 55527721 by 810 
We're looking to find how many times 810 goes into 55527721.

Going ahead to step 1:
810 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 810

Going ahead to step 2:
810 can be fit into 55 0 times, resulting in a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Bring next digit (5) of the dividend behind the 55 and repeat the process: 555 / 810

Step 3:
555 divided by 810 is 0 with a remainder of 555.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 555, we end up with 555.
Append the next digit (2) from the dividend to 555 and continue with: 5552 / 810

Moving on to step 4:
5552 divided by 810 is 6 with a remainder of 692.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 4860 from 5552 leaves us with 692.
Append the next digit (7) from the dividend to 692 and continue with: 6927 / 810

Going ahead to step 5:
810 can be fit into 6927 8 times, resulting in a remainder of 447.
Record the quotient 8 as the next digit in the result. 
Result so far: 68.0
If we take 6480 away from 6927, we end up with 447.
Fetch the next digit (7) from the dividend, attach it to 447 and continue: 4477 / 810

Moving on to step 6:
The number 810 fits into 4477 5 times, leaving a remainder of 427.
Put 5 as the next digit of the answer. 
Result so far: 685.0
Subtract 4050 from 4477 to get 427.
Grab the next digit (2) from the dividend, add it to 427, then carry on: 4272 / 810

Step 7:
The number 810 fits into 4272 5 times, leaving a remainder of 222.
The next digit of our result is 5. 
Result so far: 6855.0
If we take 4050 away from 4272, we end up with 222.
Take the next digit (1) from the dividend and append it to 222, then repeat: 2221 / 810

Advancing to step 8:
810 goes into 2221 2 times with a remainder of 601.
The number 2 becomes the next digit in our result. 
Result so far: 68552.0
The remainder is 601 after subtracting 1620 from 2221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Moving on to step 9:
If we divide 6010 by 810, we get 7 and a remainder of 340.
Use 7 as the next digit of our solution. 
Result so far: 68552.7
Deduct 5670 from 6010 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 10:
810 goes into 3400 4 times with a remainder of 160.
The number 4 becomes the next digit in our result. 
Result so far: 68552.74
The remainder is 160 after subtracting 3240 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Step 11:
If we divide 1600 by 810, we get 1 and a remainder of 790.
Put 1 as the next digit of the answer. 
Result so far: 68552.741
The remainder is 790 after subtracting 810 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Advancing to step 12:
810 goes into 7900 9 times with a remainder of 610.
The number 9 becomes the next digit in our result. 
Result so far: 68552.7419
If we take 7290 away from 7900, we end up with 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

Step 13:
810 goes into 6100 7 times with a remainder of 430.
Put 7 as the next digit of the answer. 
Result so far: 68552.74197
If we subtract 5670 from 6100, we get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Let's proceed to step 14:
810 goes into 4300 5 times with a remainder of 250.
The number 5 becomes the next digit in our result. 
Result so far: 68552.741975
If we subtract 4050 from 4300, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 15:
The number 810 fits into 2500 3 times, leaving a remainder of 70.
Record the quotient 3 as the next digit in the result. 
Result so far: 68552.7419753
Deduct 2430 from 2500 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 16:
810 can be fit into 700 0 times, resulting in a remainder of 700.
Write down 0 as next digit of the result. 
Result so far: 68552.7419753
The remainder is 700 after subtracting 0 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The final outcome is 68552.7419753, with a leftover of 7e-07.
