459190 ÷ 40 
We're looking to find how many times 40 goes into 459190.

Moving on to step 1:
40 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 40

Step 2:
40 can be fit into 45 1 times, resulting in a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 40 from 45 and we're left with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 40

Going ahead to step 3:
When dividing 59 by 40, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtracting 40 from 59 leaves us with 19.
Grab the next digit (1) from the dividend, add it to 19, then carry on: 191 / 40

Let's proceed to step 4:
40 goes into 191 4 times with a remainder of 31.
Write down 4 as next digit of the result. 
Result so far: 114.0
If we take 160 away from 191, we end up with 31.
Append the next digit (9) from the dividend to 31 and continue with: 319 / 40

Going ahead to step 5:
If we divide 319 by 40, we get 7 and a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 1147.0
Deduct 280 from 319 and we're left with 39.
Include the next digit (0) from the dividend after 39, then repeat: 390 / 40

Step 6:
When dividing 390 by 40, we get 9 with a remainder of 30.
Record the quotient 9 as the next digit in the result. 
Result so far: 11479.0
Deduct 360 from 390 and we're left 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.

Going ahead to step 7:
The number 40 fits into 300 7 times, leaving a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 11479.7
Deduct 280 from 300 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.

Moving on to step 8:
40 can be fit into 200 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 11479.75
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.

Advancing to step 9:
When dividing 0 by 40, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11479.75
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.

Moving on to step 10:
40 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 11479.75
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 11479.75, with a leftover of 0.0.
