749148 divided by 40 
Let's see how many times 40 fits into 749148.

Advancing to step 1:
The number 40 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 40

Let's proceed to step 2:
40 goes into 74 1 times with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 40 from 74 to get 34.
Grab the next digit (9) from the dividend, add it to 34, then carry on: 349 / 40

Moving on to step 3:
40 goes into 349 8 times with a remainder of 29.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we take 320 away from 349, we end up with 29.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 40

On to step 4:
291 divided by 40 is 7 with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 187.0
Subtracting 280 from 291 leaves us with 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 40

Moving on to step 5:
40 can be fit into 114 2 times, resulting in a remainder of 34.
Record the quotient 2 as the next digit in the result. 
Result so far: 1872.0
If we take 80 away from 114, we end up with 34.
Bring next digit (8) of the dividend behind the 34 and repeat the process: 348 / 40

Advancing to step 6:
348 divided by 40 is 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 18728.0
If we subtract 320 from 348, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 7:
When dividing 280 by 40, we get 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 18728.7
Subtracting 280 from 280 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.

Moving on to step 8:
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: 18728.7
If we take 0 away from 0, we end up 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.

Step 9:
If we divide 0 by 40, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18728.7
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 18728.7, with a leftover of 0.0.
