506066 ÷ 40 
The aim is to understand the frequency of 40 in 506066.

Advancing to step 1:
When dividing 5 by 40, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 40

Advancing to step 2:
50 divided by 40 is 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 40 from 50 leaves us with 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 40

Advancing to step 3:
The number 40 fits into 106 2 times, leaving a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 26 after subtracting 80 from 106.
Bring next digit (0) of the dividend behind the 26 and repeat the process: 260 / 40

Going ahead to step 4:
If we divide 260 by 40, we get 6 and a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 126.0
Deduct 240 from 260 and we're left with 20.
Grab the next digit (6) from the dividend, add it to 20, then carry on: 206 / 40

Advancing to step 5:
40 can be fit into 206 5 times, resulting in a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 1265.0
Subtracting 200 from 206 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 40

Going ahead to step 6:
40 can be fit into 66 1 times, resulting in a remainder of 26.
Write down 1 as next digit of the result. 
Result so far: 12651.0
Subtracting 40 from 66 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.

Going ahead to step 7:
40 goes into 260 6 times with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 12651.6
Subtracting 240 from 260 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
200 divided by 40 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 12651.65
If we take 200 away from 200, we end up 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.

Moving on to step 9:
The number 40 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 12651.65
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.

Moving on to step 10:
0 divided by 40 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12651.65
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.

After the division, we end up with 12651.65 and a remainder of 0.0.
