306990 ÷ 46 
The aim is to understand the frequency of 46 in 306990.

On to step 1:
46 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 46

On to step 2:
When dividing 30 by 46, we get 0 with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 46

Going ahead to step 3:
306 divided by 46 is 6 with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 30 after subtracting 276 from 306.
Take the next digit (9) from the dividend and append it to 30, then repeat: 309 / 46

Step 4:
46 goes into 309 6 times with a remainder of 33.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
Deduct 276 from 309 and we're left with 33.
Take the next digit (9) from the dividend and append it to 33, then repeat: 339 / 46

Moving on to step 5:
If we divide 339 by 46, we get 7 and a remainder of 17.
The next digit of our result is 7. 
Result so far: 667.0
Deduct 322 from 339 and we're left with 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 46

Step 6:
If we divide 170 by 46, we get 3 and a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 6673.0
If we take 138 away from 170, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 7:
46 can be fit into 320 6 times, resulting in a remainder of 44.
Put 6 as the next digit of the answer. 
Result so far: 6673.6
If we take 276 away from 320, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 8:
When dividing 440 by 46, we get 9 with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 6673.69
Subtracting 414 from 440 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 9:
260 divided by 46 is 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 6673.695
The remainder is 30 after subtracting 230 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
When dividing 300 by 46, we get 6 with a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 6673.6956
Subtracting 276 from 300 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
46 goes into 240 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 6673.69565
If we take 230 away from 240, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 12:
100 divided by 46 is 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 6673.695652
Subtract 92 from 100 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
80 divided by 46 is 1 with a remainder of 34.
Use 1 as the next digit of our solution. 
Result so far: 6673.6956521
If we take 46 away from 80, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 14:
340 divided by 46 is 7 with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 6673.69565217
If we take 322 away from 340, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 6673.69565217, and the remainder is 1.8e-08.
