52217120 divided by 278 
We want to divide 52217120 by 278.

Advancing to step 1:
If we divide 5 by 278, we get 0 and 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.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 278

On to step 2:
If we divide 52 by 278, we get 0 and a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Fetch the next digit (2) from the dividend, attach it to 52 and continue: 522 / 278

On to step 3:
522 divided by 278 is 1 with a remainder of 244.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 278 from 522 and we're left with 244.
Fetch the next digit (1) from the dividend, attach it to 244 and continue: 2441 / 278

On to step 4:
When dividing 2441 by 278, we get 8 with a remainder of 217.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
If we take 2224 away from 2441, we end up with 217.
Include the next digit (7) from the dividend after 217, then repeat: 2177 / 278

Step 5:
When dividing 2177 by 278, we get 7 with a remainder of 231.
Use 7 as the next digit of our solution. 
Result so far: 187.0
Subtract 1946 from 2177 to get 231.
Bring next digit (1) of the dividend behind the 231 and repeat the process: 2311 / 278

Moving on to step 6:
The number 278 fits into 2311 8 times, leaving a remainder of 87.
The number 8 becomes the next digit in our result. 
Result so far: 1878.0
If we take 2224 away from 2311, we end up with 87.
Grab the next digit (2) from the dividend, add it to 87, then carry on: 872 / 278

Going ahead to step 7:
278 goes into 872 3 times with a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 18783.0
The remainder is 38 after subtracting 834 from 872.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 278

Advancing to step 8:
When dividing 380 by 278, we get 1 with a remainder of 102.
The number 1 becomes the next digit in our result. 
Result so far: 187831.0
Subtract 278 from 380 to get 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

Advancing to step 9:
278 can be fit into 1020 3 times, resulting in a remainder of 186.
Record the quotient 3 as the next digit in the result. 
Result so far: 187831.3
The remainder is 186 after subtracting 834 from 1020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 10:
When dividing 1860 by 278, we get 6 with a remainder of 192.
Write down 6 as next digit of the result. 
Result so far: 187831.36
If we take 1668 away from 1860, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 11:
1920 divided by 278 is 6 with a remainder of 252.
The number 6 becomes the next digit in our result. 
Result so far: 187831.366
Subtract 1668 from 1920 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

The final outcome is 187831.366, with a leftover of 0.0252.
