Let's divide 724590 by 40
The aim is to understand the frequency of 40 in 724590.

Advancing to step 1:
When dividing 7 by 40, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 40

On to step 2:
40 can be fit into 72 1 times, resulting in a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 40 from 72 and we're left with 32.
Include the next digit (4) from the dividend after 32, then repeat: 324 / 40

On to step 3:
324 divided by 40 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we take 320 away from 324, we end up with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 40

Let's proceed to step 4:
45 divided by 40 is 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 181.0
Subtract 40 from 45 to get 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 40

Let's proceed to step 5:
When dividing 59 by 40, we get 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1811.0
If we subtract 40 from 59, we get 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 40

Let's proceed to step 6:
40 goes into 190 4 times with a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 18114.0
If we take 160 away from 190, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
If we divide 300 by 40, we get 7 and a remainder of 20.
Use 7 as the next digit of our solution. 
Result so far: 18114.7
If we subtract 280 from 300, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
The number 40 fits into 200 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 18114.75
The remainder is 0 after subtracting 200 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
If we divide 0 by 40, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 18114.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed 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: 18114.75
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.

In conclusion, the division gives 18114.75 with a balance of 0.0.
