We're dividing 436191 by 40 
Our goal is to divide 436191 by 40.

On to step 1:
If we divide 4 by 40, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 40

Going ahead to step 2:
When dividing 43 by 40, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 40 from 43 leaves us with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 40

Let's proceed to step 3:
The number 40 fits into 36 0 times, leaving a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 36 leaves us with 36.
Append the next digit (1) from the dividend to 36 and continue with: 361 / 40

Step 4:
The number 40 fits into 361 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 109.0
Subtract 360 from 361 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 40

Advancing to step 5:
If we divide 19 by 40, we get 0 and a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 1090.0
If we subtract 0 from 19, we get 19.
Fetch the next digit (1) from the dividend, attach it to 19 and continue: 191 / 40

Advancing to step 6:
When dividing 191 by 40, we get 4 with a remainder of 31.
Use 4 as the next digit of our solution. 
Result so far: 10904.0
Subtract 160 from 191 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 7:
40 goes into 310 7 times with a remainder of 30.
Record the quotient 7 as the next digit in the result. 
Result so far: 10904.7
The remainder is 30 after subtracting 280 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
40 goes into 300 7 times with a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 10904.77
If we take 280 away from 300, we end up 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.

The quotient of the division is 10904.77, and the remainder is 0.02.
