We're dividing 451656 by 40 
Our goal is to divide 451656 by 40.

Advancing to step 1:
When dividing 4 by 40, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 40

Going ahead to step 2:
When dividing 45 by 40, we get 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 40 from 45 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 40

Advancing to step 3:
40 goes into 51 1 times with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 11.0
The remainder is 11 after subtracting 40 from 51.
Take the next digit (6) from the dividend and append it to 11, then repeat: 116 / 40

Going ahead to step 4:
40 goes into 116 2 times with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 112.0
Subtract 80 from 116 to get 36.
Take the next digit (5) from the dividend and append it to 36, then repeat: 365 / 40

Moving on to step 5:
40 can be fit into 365 9 times, resulting in a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 1129.0
Subtracting 360 from 365 leaves us with 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 40

Advancing to step 6:
40 can be fit into 56 1 times, resulting in a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 11291.0
Subtract 40 from 56 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 7:
The number 40 fits into 160 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 11291.4
Subtract 160 from 160 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.

Let's proceed to step 8:
If we divide 0 by 40, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 11291.4
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.

On to step 9:
40 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 11291.4
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.

Our division results in 11291.4 with a remaining 0.0.
