53804134 divided by 878 
We want to divide 53804134 by 878.

Advancing to step 1:
878 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 878

Going ahead to step 2:
53 divided by 878 is 0 with a remainder of 53.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 53 after subtracting 0 from 53.
Bring next digit (8) of the dividend behind the 53 and repeat the process: 538 / 878

Moving on to step 3:
878 can be fit into 538 0 times, resulting in a remainder of 538.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 538, we get 538.
Append the next digit (0) from the dividend to 538 and continue with: 5380 / 878

Moving on to step 4:
878 can be fit into 5380 6 times, resulting in a remainder of 112.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 5268 from 5380 leaves us with 112.
Take the next digit (4) from the dividend and append it to 112, then repeat: 1124 / 878

Advancing to step 5:
1124 divided by 878 is 1 with a remainder of 246.
Record the quotient 1 as the next digit in the result. 
Result so far: 61.0
Deduct 878 from 1124 and we're left with 246.
Grab the next digit (1) from the dividend, add it to 246, then carry on: 2461 / 878

Going ahead to step 6:
The number 878 fits into 2461 2 times, leaving a remainder of 705.
The number 2 becomes the next digit in our result. 
Result so far: 612.0
If we subtract 1756 from 2461, we get 705.
Include the next digit (3) from the dividend after 705, then repeat: 7053 / 878

Moving on to step 7:
878 goes into 7053 8 times with a remainder of 29.
The next digit of our result is 8. 
Result so far: 6128.0
Deduct 7024 from 7053 and we're left with 29.
Fetch the next digit (4) from the dividend, attach it to 29 and continue: 294 / 878

Advancing to step 8:
If we divide 294 by 878, we get 0 and a remainder of 294.
The next digit of our result is 0. 
Result so far: 61280.0
If we subtract 0 from 294, we get 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

Let's proceed to step 9:
When dividing 2940 by 878, we get 3 with a remainder of 306.
Record the quotient 3 as the next digit in the result. 
Result so far: 61280.3
If we take 2634 away from 2940, we end up with 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Advancing to step 10:
878 can be fit into 3060 3 times, resulting in a remainder of 426.
Record the quotient 3 as the next digit in the result. 
Result so far: 61280.33
If we take 2634 away from 3060, we end up with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

The final outcome is 61280.33, with a leftover of 0.426.
