Let's divide 583181 by 40
The aim is to understand the frequency of 40 in 583181.

Going ahead to step 1:
When dividing 5 by 40, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 40

Advancing to step 2:
40 goes into 58 1 times 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.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 40

Moving on to step 3:
40 goes into 183 4 times with a remainder of 23.
The next digit of our result is 4. 
Result so far: 14.0
If we take 160 away from 183, we end up with 23.
Fetch the next digit (1) from the dividend, attach it to 23 and continue: 231 / 40

Moving on to step 4:
When dividing 231 by 40, we get 5 with a remainder of 31.
The number 5 becomes the next digit in our result. 
Result so far: 145.0
The remainder is 31 after subtracting 200 from 231.
Grab the next digit (8) from the dividend, add it to 31, then carry on: 318 / 40

Let's proceed to step 5:
The number 40 fits into 318 7 times, leaving a remainder of 38.
The next digit of our result is 7. 
Result so far: 1457.0
Subtracting 280 from 318 leaves us with 38.
Append the next digit (1) from the dividend to 38 and continue with: 381 / 40

Let's proceed to step 6:
The number 40 fits into 381 9 times, leaving a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 14579.0
The remainder is 21 after subtracting 360 from 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
When dividing 210 by 40, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 14579.5
Subtract 200 from 210 to get 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 8:
40 can be fit into 100 2 times, resulting in a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 14579.52
If we subtract 80 from 100, 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.

Moving on to step 9:
The number 40 fits into 200 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 14579.525
Deduct 200 from 200 and we're left 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.

On to step 10:
40 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 14579.525
Deduct 0 from 0 and we're left 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 11:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 14579.525
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 14579.525, with a leftover of 0.0.
