153780 divided by 40 
We're looking to find how many times 40 goes into 153780.

Let's proceed to step 1:
40 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 40

Let's proceed to step 2:
The number 40 fits into 15 0 times, leaving a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Fetch the next digit (3) from the dividend, attach it to 15 and continue: 153 / 40

Going ahead to step 3:
When dividing 153 by 40, we get 3 with a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 120 from 153 to get 33.
Take the next digit (7) from the dividend and append it to 33, then repeat: 337 / 40

Step 4:
40 can be fit into 337 8 times, resulting in a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 38.0
The remainder is 17 after subtracting 320 from 337.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 40

Going ahead to step 5:
178 divided by 40 is 4 with a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 384.0
If we take 160 away from 178, we end up with 18.
Take the next digit (0) from the dividend and append it to 18, then repeat: 180 / 40

Moving on to step 6:
40 can be fit into 180 4 times, resulting in a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 3844.0
Subtracting 160 from 180 leaves us 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.

Going ahead to step 7:
If we divide 200 by 40, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 3844.5
If we subtract 200 from 200, 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.

Advancing to step 8:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3844.5
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.

Step 9:
40 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3844.5
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.

The final outcome is 3844.5, with a leftover of 0.0.
