We're dividing 73155 by 40 
We're looking to find how many times 40 goes into 73155.

Let's proceed to step 1:
40 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 40

On to step 2:
If we divide 73 by 40, we get 1 and a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 40 away from 73, we end up with 33.
Include the next digit (1) from the dividend after 33, then repeat: 331 / 40

Advancing to step 3:
The number 40 fits into 331 8 times, leaving a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we subtract 320 from 331, we get 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 40

On to step 4:
115 divided by 40 is 2 with a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 182.0
Subtract 80 from 115 to get 35.
Take the next digit (5) from the dividend and append it to 35, then repeat: 355 / 40

Advancing to step 5:
When dividing 355 by 40, we get 8 with a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 1828.0
The remainder is 35 after subtracting 320 from 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 6:
When dividing 350 by 40, we get 8 with a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 1828.8
Deduct 320 from 350 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
300 divided by 40 is 7 with a remainder of 20.
The next digit of our result is 7. 
Result so far: 1828.87
If we subtract 280 from 300, 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.

Advancing to step 8:
The number 40 fits into 200 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 1828.875
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 9:
0 divided by 40 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1828.875
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 10:
When dividing 0 by 40, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1828.875
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.

The final outcome is 1828.875, with a leftover of 0.0.
