53977293 ÷ 66 
Our goal is to divide 53977293 by 66.

Let's proceed to step 1:
If we divide 5 by 66, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 66

Moving on to step 2:
66 goes into 53 0 times with a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Bring next digit (9) of the dividend behind the 53 and repeat the process: 539 / 66

On to step 3:
66 can be fit into 539 8 times, resulting in a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 528 from 539 to get 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 66

On to step 4:
66 can be fit into 117 1 times, resulting in a remainder of 51.
The next digit of our result is 1. 
Result so far: 81.0
If we subtract 66 from 117, we get 51.
Include the next digit (7) from the dividend after 51, then repeat: 517 / 66

Going ahead to step 5:
66 can be fit into 517 7 times, resulting in a remainder of 55.
The next digit of our result is 7. 
Result so far: 817.0
If we subtract 462 from 517, we get 55.
Include the next digit (2) from the dividend after 55, then repeat: 552 / 66

Step 6:
When dividing 552 by 66, we get 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 8178.0
Subtracting 528 from 552 leaves us with 24.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 66

Advancing to step 7:
66 can be fit into 249 3 times, resulting in a remainder of 51.
Write down 3 as next digit of the result. 
Result so far: 81783.0
Deduct 198 from 249 and we're left with 51.
Grab the next digit (3) from the dividend, add it to 51, then carry on: 513 / 66

Let's proceed to step 8:
66 can be fit into 513 7 times, resulting in a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 817837.0
If we subtract 462 from 513, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 9:
66 goes into 510 7 times with a remainder of 48.
Record the quotient 7 as the next digit in the result. 
Result so far: 817837.7
If we subtract 462 from 510, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
480 divided by 66 is 7 with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 817837.77
If we subtract 462 from 480, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

In conclusion, the division gives 817837.77 with a balance of 0.018.
