591424 ÷ 40 
Our goal is to divide 591424 by 40.

Moving on to step 1:
5 divided by 40 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 40

Advancing to step 2:
The number 40 fits into 59 1 times, leaving a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 19 after subtracting 40 from 59.
Include the next digit (1) from the dividend after 19, then repeat: 191 / 40

Moving on to step 3:
40 can be fit into 191 4 times, resulting in a remainder of 31.
Use 4 as the next digit of our solution. 
Result so far: 14.0
Subtract 160 from 191 to get 31.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 40

Let's proceed to step 4:
40 goes into 314 7 times with a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 147.0
If we subtract 280 from 314, we get 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 40

Going ahead to step 5:
40 goes into 342 8 times with a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 1478.0
The remainder is 22 after subtracting 320 from 342.
Append the next digit (4) from the dividend to 22 and continue with: 224 / 40

Going ahead to step 6:
40 can be fit into 224 5 times, resulting in a remainder of 24.
Record the quotient 5 as the next digit in the result. 
Result so far: 14785.0
Subtract 200 from 224 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 7:
40 goes into 240 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 14785.6
The remainder is 0 after subtracting 240 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
40 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 14785.6
Subtract 0 from 0 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.

Advancing to step 9:
If we divide 0 by 40, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 14785.6
If we subtract 0 from 0, we 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.

The final outcome is 14785.6, with a leftover of 0.0.
