We're dividing 749181 by 40 
We want to divide 749181 by 40.

Moving on to step 1:
40 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 40

On to step 2:
74 divided by 40 is 1 with a remainder of 34.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 40 from 74 leaves us with 34.
Grab the next digit (9) from the dividend, add it to 34, then carry on: 349 / 40

Advancing to step 3:
When dividing 349 by 40, we get 8 with a remainder of 29.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 320 from 349, we get 29.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 40

Step 4:
If we divide 291 by 40, we get 7 and a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 187.0
Subtracting 280 from 291 leaves us with 11.
Take the next digit (8) from the dividend and append it to 11, then repeat: 118 / 40

Going ahead to step 5:
40 goes into 118 2 times with a remainder of 38.
Use 2 as the next digit of our solution. 
Result so far: 1872.0
If we subtract 80 from 118, we get 38.
Include the next digit (1) from the dividend after 38, then repeat: 381 / 40

Advancing to step 6:
381 divided by 40 is 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 18729.0
Subtract 360 from 381 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
If we divide 210 by 40, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 18729.5
Subtracting 200 from 210 leaves us 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.
The number 2 becomes the next digit in our result. 
Result so far: 18729.52
Subtracting 80 from 100 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 9:
200 divided by 40 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 18729.525
Deduct 200 from 200 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:
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: 18729.525
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.

Let's proceed to step 11:
The number 40 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18729.525
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 result is 18729.525 with a remainder of 0.0.
