We look at the division of 375645 by 40 
Let's see how many times 40 fits into 375645.

Step 1:
40 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 40

Moving on to step 2:
When dividing 37 by 40, we get 0 with a remainder of 37.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Take the next digit (5) from the dividend and append it to 37, then repeat: 375 / 40

Moving on to step 3:
40 goes into 375 9 times with a remainder of 15.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 360 from 375 and we're left with 15.
Bring next digit (6) of the dividend behind the 15 and repeat the process: 156 / 40

Let's proceed to step 4:
40 can be fit into 156 3 times, resulting in a remainder of 36.
Write down 3 as next digit of the result. 
Result so far: 93.0
The remainder is 36 after subtracting 120 from 156.
Fetch the next digit (4) from the dividend, attach it to 36 and continue: 364 / 40

On to step 5:
364 divided by 40 is 9 with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 939.0
Deduct 360 from 364 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 40

Moving on to step 6:
40 goes into 45 1 times with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 9391.0
Subtracting 40 from 45 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
If we divide 50 by 40, we get 1 and a remainder of 10.
The next digit of our result is 1. 
Result so far: 9391.1
If we take 40 away from 50, 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.

Let's proceed to step 8:
40 goes into 100 2 times with a remainder of 20.
Put 2 as the next digit of the answer. 
Result so far: 9391.12
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.

Going ahead to step 9:
40 goes into 200 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 9391.125
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.

Advancing to step 10:
0 divided by 40 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 9391.125
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.

Advancing to step 11:
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: 9391.125
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.

The quotient of the division is 9391.125, and the remainder is 0.0.
