We're dividing 51563344 by 878 
We're looking to find how many times 878 goes into 51563344.

Moving on to step 1:
When dividing 5 by 878, we get 0 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.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 878

Step 2:
The number 878 fits into 51 0 times, leaving a remainder of 51.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 51 to get 51.
Take the next digit (5) from the dividend and append it to 51, then repeat: 515 / 878

Step 3:
878 goes into 515 0 times with a remainder of 515.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 515, we get 515.
Fetch the next digit (6) from the dividend, attach it to 515 and continue: 5156 / 878

On to step 4:
The number 878 fits into 5156 5 times, leaving a remainder of 766.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 4390 from 5156 and we're left with 766.
Bring next digit (3) of the dividend behind the 766 and repeat the process: 7663 / 878

On to step 5:
When dividing 7663 by 878, we get 8 with a remainder of 639.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Subtract 7024 from 7663 to get 639.
Take the next digit (3) from the dividend and append it to 639, then repeat: 6393 / 878

On to step 6:
If we divide 6393 by 878, we get 7 and a remainder of 247.
Use 7 as the next digit of our solution. 
Result so far: 587.0
If we subtract 6146 from 6393, we get 247.
Append the next digit (4) from the dividend to 247 and continue with: 2474 / 878

Going ahead to step 7:
If we divide 2474 by 878, we get 2 and a remainder of 718.
Put 2 as the next digit of the answer. 
Result so far: 5872.0
If we subtract 1756 from 2474, we get 718.
Append the next digit (4) from the dividend to 718 and continue with: 7184 / 878

Going ahead to step 8:
The number 878 fits into 7184 8 times, leaving a remainder of 160.
Record the quotient 8 as the next digit in the result. 
Result so far: 58728.0
Subtract 7024 from 7184 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 9:
1600 divided by 878 is 1 with a remainder of 722.
Put 1 as the next digit of the answer. 
Result so far: 58728.1
If we take 878 away from 1600, we end up with 722.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

Going ahead to step 10:
The number 878 fits into 7220 8 times, leaving a remainder of 196.
Record the quotient 8 as the next digit in the result. 
Result so far: 58728.18
Deduct 7024 from 7220 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Advancing to step 11:
878 can be fit into 1960 2 times, resulting in a remainder of 204.
The number 2 becomes the next digit in our result. 
Result so far: 58728.182
The remainder is 204 after subtracting 1756 from 1960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Advancing to step 12:
The number 878 fits into 2040 2 times, leaving a remainder of 284.
Use 2 as the next digit of our solution. 
Result so far: 58728.1822
If we take 1756 away from 2040, we end up with 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Our division results in 58728.1822 with a remaining 0.00284.
