686350 ÷ 74 
The aim is to understand the frequency of 74 in 686350.

Moving on to step 1:
74 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 74

Let's proceed to step 2:
The number 74 fits into 68 0 times, leaving a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Grab the next digit (6) from the dividend, add it to 68, then carry on: 686 / 74

Going ahead to step 3:
When dividing 686 by 74, we get 9 with a remainder of 20.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtract 666 from 686 to get 20.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 74

Step 4:
If we divide 203 by 74, we get 2 and a remainder of 55.
Record the quotient 2 as the next digit in the result. 
Result so far: 92.0
The remainder is 55 after subtracting 148 from 203.
Take the next digit (5) from the dividend and append it to 55, then repeat: 555 / 74

Let's proceed to step 5:
555 divided by 74 is 7 with a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 927.0
If we subtract 518 from 555, we get 37.
Grab the next digit (0) from the dividend, add it to 37, then carry on: 370 / 74

Moving on to step 6:
370 divided by 74 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 9275.0
Deduct 370 from 370 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
74 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9275.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
74 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 9275.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 9275.0, with a leftover of 0.0.
