51417286 ÷ 278 
Our goal is to divide 51417286 by 278.

Advancing to step 1:
278 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 278

Let's proceed to step 2:
51 divided by 278 is 0 with a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Bring next digit (4) of the dividend behind the 51 and repeat the process: 514 / 278

Step 3:
When dividing 514 by 278, we get 1 with a remainder of 236.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 278 from 514 to get 236.
Bring next digit (1) of the dividend behind the 236 and repeat the process: 2361 / 278

Going ahead to step 4:
278 can be fit into 2361 8 times, resulting in a remainder of 137.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 2224 from 2361 leaves us with 137.
Take the next digit (7) from the dividend and append it to 137, then repeat: 1377 / 278

Moving on to step 5:
If we divide 1377 by 278, we get 4 and a remainder of 265.
The next digit of our result is 4. 
Result so far: 184.0
Deduct 1112 from 1377 and we're left with 265.
Take the next digit (2) from the dividend and append it to 265, then repeat: 2652 / 278

Let's proceed to step 6:
278 goes into 2652 9 times with a remainder of 150.
Record the quotient 9 as the next digit in the result. 
Result so far: 1849.0
The remainder is 150 after subtracting 2502 from 2652.
Fetch the next digit (8) from the dividend, attach it to 150 and continue: 1508 / 278

On to step 7:
If we divide 1508 by 278, we get 5 and a remainder of 118.
Put 5 as the next digit of the answer. 
Result so far: 18495.0
If we take 1390 away from 1508, we end up with 118.
Fetch the next digit (6) from the dividend, attach it to 118 and continue: 1186 / 278

Let's proceed to step 8:
If we divide 1186 by 278, we get 4 and a remainder of 74.
The number 4 becomes the next digit in our result. 
Result so far: 184954.0
Deduct 1112 from 1186 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Let's proceed to step 9:
When dividing 740 by 278, we get 2 with a remainder of 184.
Put 2 as the next digit of the answer. 
Result so far: 184954.2
Subtracting 556 from 740 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 10:
1840 divided by 278 is 6 with a remainder of 172.
Use 6 as the next digit of our solution. 
Result so far: 184954.26
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.

Going ahead to step 11:
The number 278 fits into 1720 6 times, leaving a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 184954.266
If we subtract 1668 from 1720, we get 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 184954.266 and a remainder of 0.0052.
