We're dividing 419374 by 40 
Our goal is to divide 419374 by 40.

Moving on to step 1:
4 divided by 40 is 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 (1) from the dividend, attach it to 4 and continue: 41 / 40

Advancing to step 2:
When dividing 41 by 40, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 40 from 41 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 40

Advancing to step 3:
If we divide 19 by 40, we get 0 and a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 19 to get 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 40

Advancing to step 4:
40 can be fit into 193 4 times, resulting in a remainder of 33.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
Deduct 160 from 193 and we're left with 33.
Grab the next digit (7) from the dividend, add it to 33, then carry on: 337 / 40

On to step 5:
When dividing 337 by 40, we get 8 with a remainder of 17.
The next digit of our result is 8. 
Result so far: 1048.0
Subtracting 320 from 337 leaves us with 17.
Bring next digit (4) of the dividend behind the 17 and repeat the process: 174 / 40

Going ahead to step 6:
174 divided by 40 is 4 with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 10484.0
Deduct 160 from 174 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
If we divide 140 by 40, we get 3 and a remainder of 20.
The next digit of our result is 3. 
Result so far: 10484.3
The remainder is 20 after subtracting 120 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
If we divide 200 by 40, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 10484.35
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.
Write down 0 as next digit of the result. 
Result so far: 10484.35
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.

Step 10:
If we divide 0 by 40, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 10484.35
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.

Our division results in 10484.35 with a remaining 0.0.
