We look at the division of 13345192 by 278 
The aim is to understand the frequency of 278 in 13345192.

Going ahead to step 1:
278 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 278

Step 2:
13 divided by 278 is 0 with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 278

Going ahead to step 3:
If we divide 133 by 278, we get 0 and a remainder of 133.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 133, we end up with 133.
Append the next digit (4) from the dividend to 133 and continue with: 1334 / 278

Moving on to step 4:
278 can be fit into 1334 4 times, resulting in a remainder of 222.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 1112 from 1334 and we're left with 222.
Include the next digit (5) from the dividend after 222, then repeat: 2225 / 278

Going ahead to step 5:
The number 278 fits into 2225 8 times, leaving a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
If we take 2224 away from 2225, we end up with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 278

Going ahead to step 6:
278 can be fit into 11 0 times, resulting in a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 480.0
If we subtract 0 from 11, we get 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 278

On to step 7:
If we divide 119 by 278, we get 0 and a remainder of 119.
Put 0 as the next digit of the answer. 
Result so far: 4800.0
The remainder is 119 after subtracting 0 from 119.
Take the next digit (2) from the dividend and append it to 119, then repeat: 1192 / 278

Going ahead to step 8:
If we divide 1192 by 278, we get 4 and a remainder of 80.
Record the quotient 4 as the next digit in the result. 
Result so far: 48004.0
Subtracting 1112 from 1192 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 9:
If we divide 800 by 278, we get 2 and a remainder of 244.
The next digit of our result is 2. 
Result so far: 48004.2
If we take 556 away from 800, we end up with 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Going ahead to step 10:
If we divide 2440 by 278, we get 8 and a remainder of 216.
The number 8 becomes the next digit in our result. 
Result so far: 48004.28
If we subtract 2224 from 2440, we get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 11:
If we divide 2160 by 278, we get 7 and a remainder of 214.
The number 7 becomes the next digit in our result. 
Result so far: 48004.287
If we take 1946 away from 2160, we end up with 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Going ahead to step 12:
If we divide 2140 by 278, we get 7 and a remainder of 194.
Put 7 as the next digit of the answer. 
Result so far: 48004.2877
The remainder is 194 after subtracting 1946 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

The final outcome is 48004.2877, with a leftover of 0.00194.
