72374211 ÷ 278 
The aim is to understand the frequency of 278 in 72374211.

Going ahead to step 1:
When dividing 7 by 278, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 278

On to step 2:
When dividing 72 by 278, we get 0 with a remainder of 72.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Bring next digit (3) of the dividend behind the 72 and repeat the process: 723 / 278

On to step 3:
278 can be fit into 723 2 times, resulting in a remainder of 167.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 556 from 723 and we're left with 167.
Take the next digit (7) from the dividend and append it to 167, then repeat: 1677 / 278

On to step 4:
278 can be fit into 1677 6 times, resulting in a remainder of 9.
Write down 6 as next digit of the result. 
Result so far: 26.0
The remainder is 9 after subtracting 1668 from 1677.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 278

Going ahead to step 5:
When dividing 94 by 278, we get 0 with a remainder of 94.
The next digit of our result is 0. 
Result so far: 260.0
If we subtract 0 from 94, we get 94.
Take the next digit (2) from the dividend and append it to 94, then repeat: 942 / 278

Moving on to step 6:
942 divided by 278 is 3 with a remainder of 108.
Put 3 as the next digit of the answer. 
Result so far: 2603.0
Subtract 834 from 942 to get 108.
Append the next digit (1) from the dividend to 108 and continue with: 1081 / 278

On to step 7:
278 can be fit into 1081 3 times, resulting in a remainder of 247.
Put 3 as the next digit of the answer. 
Result so far: 26033.0
The remainder is 247 after subtracting 834 from 1081.
Include the next digit (1) from the dividend after 247, then repeat: 2471 / 278

Step 8:
The number 278 fits into 2471 8 times, leaving a remainder of 247.
Record the quotient 8 as the next digit in the result. 
Result so far: 260338.0
Deduct 2224 from 2471 and we're left with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Let's proceed to step 9:
If we divide 2470 by 278, we get 8 and a remainder of 246.
Use 8 as the next digit of our solution. 
Result so far: 260338.8
Subtract 2224 from 2470 to get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

On to step 10:
2460 divided by 278 is 8 with a remainder of 236.
Put 8 as the next digit of the answer. 
Result so far: 260338.88
Deduct 2224 from 2460 and we're left with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Our division results in 260338.88 with a remaining 0.236.
