53935014 ÷ 877 
Our goal is to divide 53935014 by 877.

Advancing to step 1:
5 divided by 877 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 877

Going ahead to step 2:
When dividing 53 by 877, we get 0 with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Bring next digit (9) of the dividend behind the 53 and repeat the process: 539 / 877

Let's proceed to step 3:
The number 877 fits into 539 0 times, leaving a remainder of 539.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 539 and we're left with 539.
Fetch the next digit (3) from the dividend, attach it to 539 and continue: 5393 / 877

Moving on to step 4:
877 goes into 5393 6 times with a remainder of 131.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 5262 from 5393 leaves us with 131.
Append the next digit (5) from the dividend to 131 and continue with: 1315 / 877

Step 5:
877 goes into 1315 1 times with a remainder of 438.
The next digit of our result is 1. 
Result so far: 61.0
If we take 877 away from 1315, we end up with 438.
Bring next digit (0) of the dividend behind the 438 and repeat the process: 4380 / 877

On to step 6:
If we divide 4380 by 877, we get 4 and a remainder of 872.
Put 4 as the next digit of the answer. 
Result so far: 614.0
Deduct 3508 from 4380 and we're left with 872.
Take the next digit (1) from the dividend and append it to 872, then repeat: 8721 / 877

Moving on to step 7:
877 can be fit into 8721 9 times, resulting in a remainder of 828.
Record the quotient 9 as the next digit in the result. 
Result so far: 6149.0
Subtracting 7893 from 8721 leaves us with 828.
Append the next digit (4) from the dividend to 828 and continue with: 8284 / 877

Advancing to step 8:
877 can be fit into 8284 9 times, resulting in a remainder of 391.
Put 9 as the next digit of the answer. 
Result so far: 61499.0
Subtract 7893 from 8284 to get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Advancing to step 9:
877 can be fit into 3910 4 times, resulting in a remainder of 402.
The number 4 becomes the next digit in our result. 
Result so far: 61499.4
If we take 3508 away from 3910, we end up with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Let's proceed to step 10:
When dividing 4020 by 877, we get 4 with a remainder of 512.
Use 4 as the next digit of our solution. 
Result so far: 61499.44
If we subtract 3508 from 4020, we get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

The final outcome is 61499.44, with a leftover of 0.512.
