946558 ÷ 288 
The aim is to understand the frequency of 288 in 946558.

Advancing to step 1:
If we divide 9 by 288, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 288

Advancing to step 2:
If we divide 94 by 288, we get 0 and a remainder of 94.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 94, we end up with 94.
Append the next digit (6) from the dividend to 94 and continue with: 946 / 288

Let's proceed to step 3:
288 goes into 946 3 times with a remainder of 82.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 864 from 946, we get 82.
Bring next digit (5) of the dividend behind the 82 and repeat the process: 825 / 288

Advancing to step 4:
288 goes into 825 2 times with a remainder of 249.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Subtract 576 from 825 to get 249.
Take the next digit (5) from the dividend and append it to 249, then repeat: 2495 / 288

Moving on to step 5:
288 can be fit into 2495 8 times, resulting in a remainder of 191.
Record the quotient 8 as the next digit in the result. 
Result so far: 328.0
The remainder is 191 after subtracting 2304 from 2495.
Append the next digit (8) from the dividend to 191 and continue with: 1918 / 288

Going ahead to step 6:
If we divide 1918 by 288, we get 6 and a remainder of 190.
The next digit of our result is 6. 
Result so far: 3286.0
If we subtract 1728 from 1918, 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 7:
1900 divided by 288 is 6 with a remainder of 172.
Use 6 as the next digit of our solution. 
Result so far: 3286.6
Deduct 1728 from 1900 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 8:
If we divide 1720 by 288, we get 5 and a remainder of 280.
Put 5 as the next digit of the answer. 
Result so far: 3286.65
If we subtract 1440 from 1720, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 9:
288 can be fit into 2800 9 times, resulting in a remainder of 208.
Write down 9 as next digit of the result. 
Result so far: 3286.659
Subtracting 2592 from 2800 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Advancing to step 10:
If we divide 2080 by 288, we get 7 and a remainder of 64.
Use 7 as the next digit of our solution. 
Result so far: 3286.6597
If we take 2016 away from 2080, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 11:
If we divide 640 by 288, we get 2 and a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 3286.65972
If we take 576 away from 640, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 12:
When dividing 640 by 288, we get 2 with a remainder of 64.
The next digit of our result is 2. 
Result so far: 3286.659722
Deduct 576 from 640 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 3286.659722 with a remainder of 6.4e-06.
