We're dividing 418924 by 40 
We want to figure out the number of times 418924 can be divided by 40.

Step 1:
40 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 40

Step 2:
40 can be fit into 41 1 times, resulting in a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 40 from 41 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 40

Going ahead to step 3:
40 can be fit into 18 0 times, resulting in a remainder of 18.
The next digit of our result is 0. 
Result so far: 10.0
Subtract 0 from 18 to get 18.
Include the next digit (9) from the dividend after 18, then repeat: 189 / 40

Let's proceed to step 4:
The number 40 fits into 189 4 times, leaving a remainder of 29.
Put 4 as the next digit of the answer. 
Result so far: 104.0
Deduct 160 from 189 and we're left with 29.
Append the next digit (2) from the dividend to 29 and continue with: 292 / 40

Going ahead to step 5:
If we divide 292 by 40, we get 7 and a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 1047.0
The remainder is 12 after subtracting 280 from 292.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 40

Advancing to step 6:
The number 40 fits into 124 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 10473.0
The remainder is 4 after subtracting 120 from 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 7:
40 can be fit into 40 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 10473.1
Subtracting 40 from 40 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.

Advancing to step 8:
40 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10473.1
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 9:
If we divide 0 by 40, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 10473.1
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.

Our division results in 10473.1 with a remaining 0.0.
