We divide 48373 by 40
Our goal is to divide 48373 by 40.

On to step 1:
The number 40 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 40

Going ahead to step 2:
48 divided by 40 is 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
If we take 40 away from 48, we end up with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 40

Advancing to step 3:
83 divided by 40 is 2 with a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 3 after subtracting 80 from 83.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 40

Let's proceed to step 4:
The number 40 fits into 37 0 times, leaving a remainder of 37.
Put 0 as the next digit of the answer. 
Result so far: 120.0
Subtracting 0 from 37 leaves us with 37.
Append the next digit (3) from the dividend to 37 and continue with: 373 / 40

On to step 5:
373 divided by 40 is 9 with a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 1209.0
If we subtract 360 from 373, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 6:
The number 40 fits into 130 3 times, leaving a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 1209.3
Subtract 120 from 130 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
When dividing 100 by 40, we get 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 1209.32
If we take 80 away from 100, 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.

Advancing to step 8:
If we divide 200 by 40, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 1209.325
Subtract 200 from 200 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.

Going ahead to step 9:
0 divided by 40 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1209.325
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.

On to step 10:
The number 40 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 1209.325
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.

The final outcome is 1209.325, with a leftover of 0.0.
