52940020 ÷ 278 
Let's see how many times 278 fits into 52940020.

Going ahead to step 1:
When dividing 5 by 278, we get 0 with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 278

Moving on to step 2:
278 goes into 52 0 times with a remainder of 52.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Append the next digit (9) from the dividend to 52 and continue with: 529 / 278

Step 3:
If we divide 529 by 278, we get 1 and a remainder of 251.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 278 from 529 leaves us with 251.
Fetch the next digit (4) from the dividend, attach it to 251 and continue: 2514 / 278

Step 4:
If we divide 2514 by 278, we get 9 and a remainder of 12.
Put 9 as the next digit of the answer. 
Result so far: 19.0
If we subtract 2502 from 2514, we get 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 278

On to step 5:
If we divide 120 by 278, we get 0 and a remainder of 120.
The next digit of our result is 0. 
Result so far: 190.0
The remainder is 120 after subtracting 0 from 120.
Bring next digit (0) of the dividend behind the 120 and repeat the process: 1200 / 278

Step 6:
If we divide 1200 by 278, we get 4 and a remainder of 88.
Put 4 as the next digit of the answer. 
Result so far: 1904.0
If we subtract 1112 from 1200, we get 88.
Take the next digit (2) from the dividend and append it to 88, then repeat: 882 / 278

Moving on to step 7:
If we divide 882 by 278, we get 3 and a remainder of 48.
Record the quotient 3 as the next digit in the result. 
Result so far: 19043.0
The remainder is 48 after subtracting 834 from 882.
Take the next digit (0) from the dividend and append it to 48, then repeat: 480 / 278

Advancing to step 8:
278 can be fit into 480 1 times, resulting in a remainder of 202.
The next digit of our result is 1. 
Result so far: 190431.0
Deduct 278 from 480 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Moving on to step 9:
When dividing 2020 by 278, we get 7 with a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 190431.7
Subtract 1946 from 2020 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 10:
278 can be fit into 740 2 times, resulting in a remainder of 184.
Put 2 as the next digit of the answer. 
Result so far: 190431.72
Subtract 556 from 740 to get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Step 11:
1840 divided by 278 is 6 with a remainder of 172.
Put 6 as the next digit of the answer. 
Result so far: 190431.726
If we take 1668 away from 1840, we end up with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 12:
The number 278 fits into 1720 6 times, leaving a remainder of 52.
The next digit of our result is 6. 
Result so far: 190431.7266
Deduct 1668 from 1720 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 190431.7266 and a remainder of 0.00052.
