278160 divided by 51 
We want to figure out the number of times 278160 can be divided by 51.

Going ahead to step 1:
51 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 51

Moving on to step 2:
51 can be fit into 27 0 times, resulting in a remainder of 27.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Bring next digit (8) of the dividend behind the 27 and repeat the process: 278 / 51

Going ahead to step 3:
If we divide 278 by 51, we get 5 and a remainder of 23.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 255 from 278, we get 23.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 51

On to step 4:
If we divide 231 by 51, we get 4 and a remainder of 27.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
Subtracting 204 from 231 leaves us with 27.
Append the next digit (6) from the dividend to 27 and continue with: 276 / 51

Going ahead to step 5:
The number 51 fits into 276 5 times, leaving a remainder of 21.
The next digit of our result is 5. 
Result so far: 545.0
Subtract 255 from 276 to get 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 51

On to step 6:
When dividing 210 by 51, we get 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 5454.0
If we take 204 away from 210, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
51 can be fit into 60 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 5454.1
If we take 51 away from 60, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 8:
90 divided by 51 is 1 with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 5454.11
If we subtract 51 from 90, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Our division results in 5454.11 with a remaining 0.039.
