We're dividing 51120768 by 278 
The aim is to understand the frequency of 278 in 51120768.

Moving on to step 1:
5 divided by 278 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 278

Let's proceed to step 2:
278 goes into 51 0 times with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Take the next digit (1) from the dividend and append it to 51, then repeat: 511 / 278

Let's proceed to step 3:
When dividing 511 by 278, we get 1 with a remainder of 233.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 278 from 511 to get 233.
Take the next digit (2) from the dividend and append it to 233, then repeat: 2332 / 278

Step 4:
278 can be fit into 2332 8 times, resulting in a remainder of 108.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 2224 from 2332 and we're left with 108.
Bring next digit (0) of the dividend behind the 108 and repeat the process: 1080 / 278

On to step 5:
278 goes into 1080 3 times with a remainder of 246.
Record the quotient 3 as the next digit in the result. 
Result so far: 183.0
Subtracting 834 from 1080 leaves us with 246.
Take the next digit (7) from the dividend and append it to 246, then repeat: 2467 / 278

Moving on to step 6:
2467 divided by 278 is 8 with a remainder of 243.
The number 8 becomes the next digit in our result. 
Result so far: 1838.0
Subtracting 2224 from 2467 leaves us with 243.
Bring next digit (6) of the dividend behind the 243 and repeat the process: 2436 / 278

Step 7:
The number 278 fits into 2436 8 times, leaving a remainder of 212.
The number 8 becomes the next digit in our result. 
Result so far: 18388.0
Subtract 2224 from 2436 to get 212.
Append the next digit (8) from the dividend to 212 and continue with: 2128 / 278

On to step 8:
The number 278 fits into 2128 7 times, leaving a remainder of 182.
Write down 7 as next digit of the result. 
Result so far: 183887.0
Subtract 1946 from 2128 to get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Moving on to step 9:
1820 divided by 278 is 6 with a remainder of 152.
The number 6 becomes the next digit in our result. 
Result so far: 183887.6
Subtract 1668 from 1820 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Going ahead to step 10:
When dividing 1520 by 278, we get 5 with a remainder of 130.
Write down 5 as next digit of the result. 
Result so far: 183887.65
Deduct 1390 from 1520 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Advancing to step 11:
278 goes into 1300 4 times with a remainder of 188.
Use 4 as the next digit of our solution. 
Result so far: 183887.654
If we subtract 1112 from 1300, we get 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Step 12:
278 can be fit into 1880 6 times, resulting in a remainder of 212.
Write down 6 as next digit of the result. 
Result so far: 183887.6546
Deduct 1668 from 1880 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 13:
278 can be fit into 2120 7 times, resulting in a remainder of 174.
The number 7 becomes the next digit in our result. 
Result so far: 183887.65467
Subtracting 1946 from 2120 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

Step 14:
278 goes into 1740 6 times with a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 183887.654676
Deduct 1668 from 1740 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 15:
278 goes into 720 2 times with a remainder of 164.
Use 2 as the next digit of our solution. 
Result so far: 183887.6546762
Subtracting 556 from 720 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Advancing to step 16:
278 can be fit into 1640 5 times, resulting in a remainder of 250.
Write down 5 as next digit of the result. 
Result so far: 183887.65467625
The remainder is 250 after subtracting 1390 from 1640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The final result is 183887.65467625 with a remainder of 2.5e-07.
