We're dividing 458130 by 40 
We're looking to find how many times 40 goes into 458130.

Advancing to step 1:
40 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 40

On to step 2:
When dividing 45 by 40, we get 1 with 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.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 40

Advancing to step 3:
If we divide 58 by 40, we get 1 and a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 40 from 58 to get 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 40

Going ahead to step 4:
40 can be fit into 181 4 times, resulting in a remainder of 21.
Record the quotient 4 as the next digit in the result. 
Result so far: 114.0
Subtracting 160 from 181 leaves us with 21.
Bring next digit (3) of the dividend behind the 21 and repeat the process: 213 / 40

Advancing to step 5:
If we divide 213 by 40, we get 5 and a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 1145.0
The remainder is 13 after subtracting 200 from 213.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 40

On to step 6:
130 divided by 40 is 3 with a remainder of 10.
The next digit of our result is 3. 
Result so far: 11453.0
If we take 120 away from 130, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
40 can be fit into 100 2 times, resulting in a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 11453.2
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 8:
When dividing 200 by 40, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 11453.25
Subtracting 200 from 200 leaves us 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 9:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11453.25
Subtracting 0 from 0 leaves us 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.

Going ahead to step 10:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11453.25
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.

The quotient of the division is 11453.25, and the remainder is 0.0.
