586254 ÷ 40 
The aim is to understand the frequency of 40 in 586254.

Moving on to step 1:
40 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 40

Advancing to step 2:
When dividing 58 by 40, we get 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 18 after subtracting 40 from 58.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 40

Going ahead to step 3:
The number 40 fits into 186 4 times, leaving a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 14.0
Deduct 160 from 186 and we're left with 26.
Fetch the next digit (2) from the dividend, attach it to 26 and continue: 262 / 40

Let's proceed to step 4:
40 can be fit into 262 6 times, resulting in a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 146.0
If we subtract 240 from 262, we get 22.
Append the next digit (5) from the dividend to 22 and continue with: 225 / 40

On to step 5:
225 divided by 40 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 1465.0
If we take 200 away from 225, we end up with 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 40

Going ahead to step 6:
254 divided by 40 is 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 14656.0
Subtracting 240 from 254 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
The number 40 fits into 140 3 times, leaving a remainder of 20.
The number 3 becomes the next digit in our result. 
Result so far: 14656.3
Deduct 120 from 140 and we're left 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.

Advancing to step 8:
40 can be fit into 200 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 14656.35
Subtract 200 from 200 to 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.

Going ahead to step 9:
When dividing 0 by 40, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 14656.35
If we take 0 away from 0, 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 10:
If we divide 0 by 40, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 14656.35
If we take 0 away from 0, 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.

The final outcome is 14656.35, with a leftover of 0.0.
