We look at the division of 69166975 by 278 
The aim is to understand the frequency of 278 in 69166975.

On to step 1:
The number 278 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 278

Moving on to step 2:
278 goes into 69 0 times with a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Take the next digit (1) from the dividend and append it to 69, then repeat: 691 / 278

On to step 3:
278 goes into 691 2 times with a remainder of 135.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 556 from 691, we get 135.
Take the next digit (6) from the dividend and append it to 135, then repeat: 1356 / 278

On to step 4:
The number 278 fits into 1356 4 times, leaving a remainder of 244.
Put 4 as the next digit of the answer. 
Result so far: 24.0
If we subtract 1112 from 1356, we get 244.
Take the next digit (6) from the dividend and append it to 244, then repeat: 2446 / 278

Moving on to step 5:
2446 divided by 278 is 8 with a remainder of 222.
Record the quotient 8 as the next digit in the result. 
Result so far: 248.0
Deduct 2224 from 2446 and we're left with 222.
Bring next digit (9) of the dividend behind the 222 and repeat the process: 2229 / 278

Moving on to step 6:
278 can be fit into 2229 8 times, resulting in a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 2488.0
If we take 2224 away from 2229, we end up with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 278

Let's proceed to step 7:
57 divided by 278 is 0 with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 24880.0
If we take 0 away from 57, we end up with 57.
Include the next digit (5) from the dividend after 57, then repeat: 575 / 278

Advancing to step 8:
278 goes into 575 2 times with a remainder of 19.
Write down 2 as next digit of the result. 
Result so far: 248802.0
The remainder is 19 after subtracting 556 from 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 9:
190 divided by 278 is 0 with a remainder of 190.
Use 0 as the next digit of our solution. 
Result so far: 248802.0
If we subtract 0 from 190, we get 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 10:
If we divide 1900 by 278, we get 6 and a remainder of 232.
Write down 6 as next digit of the result. 
Result so far: 248802.06
Subtract 1668 from 1900 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Step 11:
The number 278 fits into 2320 8 times, leaving a remainder of 96.
Use 8 as the next digit of our solution. 
Result so far: 248802.068
Subtracting 2224 from 2320 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 12:
When dividing 960 by 278, we get 3 with a remainder of 126.
Use 3 as the next digit of our solution. 
Result so far: 248802.0683
The remainder is 126 after subtracting 834 from 960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 13:
If we divide 1260 by 278, we get 4 and a remainder of 148.
Write down 4 as next digit of the result. 
Result so far: 248802.06834
Subtract 1112 from 1260 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Going ahead to step 14:
278 goes into 1480 5 times with a remainder of 90.
Write down 5 as next digit of the result. 
Result so far: 248802.068345
If we take 1390 away from 1480, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 15:
900 divided by 278 is 3 with a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 248802.0683453
The remainder is 66 after subtracting 834 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 16:
When dividing 660 by 278, we get 2 with a remainder of 104.
Put 2 as the next digit of the answer. 
Result so far: 248802.06834532
Subtracting 556 from 660 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Our division results in 248802.06834532 with a remaining 1.04e-07.
