278685 ÷ 74 
The aim is to understand the frequency of 74 in 278685.

Step 1:
The number 74 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 74

Advancing to step 2:
74 can be fit into 27 0 times, resulting in a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 27 to get 27.
Append the next digit (8) from the dividend to 27 and continue with: 278 / 74

Moving on to step 3:
If we divide 278 by 74, we get 3 and a remainder of 56.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 56 after subtracting 222 from 278.
Bring next digit (6) of the dividend behind the 56 and repeat the process: 566 / 74

Advancing to step 4:
When dividing 566 by 74, we get 7 with a remainder of 48.
Write down 7 as next digit of the result. 
Result so far: 37.0
The remainder is 48 after subtracting 518 from 566.
Take the next digit (8) from the dividend and append it to 48, then repeat: 488 / 74

Let's proceed to step 5:
When dividing 488 by 74, we get 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 376.0
Subtracting 444 from 488 leaves us with 44.
Grab the next digit (5) from the dividend, add it to 44, then carry on: 445 / 74

Advancing to step 6:
The number 74 fits into 445 6 times, leaving a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 3766.0
If we take 444 away from 445, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
74 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 3766.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
When dividing 100 by 74, we get 1 with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 3766.01
Subtract 74 from 100 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 9:
260 divided by 74 is 3 with a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 3766.013
Subtracting 222 from 260 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 10:
When dividing 380 by 74, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 3766.0135
Subtract 370 from 380 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 11:
74 goes into 100 1 times with a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 3766.01351
Subtract 74 from 100 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 12:
260 divided by 74 is 3 with a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 3766.013513
If we subtract 222 from 260, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 13:
The number 74 fits into 380 5 times, leaving a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 3766.0135135
Subtract 370 from 380 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
The number 74 fits into 100 1 times, leaving a remainder of 26.
Put 1 as the next digit of the answer. 
Result so far: 3766.01351351
Subtract 74 from 100 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 3766.01351351, with a leftover of 2.6e-08.
