148910 ÷ 40 
We're looking to find how many times 40 goes into 148910.

Moving on to step 1:
The number 40 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 40

Step 2:
If we divide 14 by 40, we get 0 and a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Grab the next digit (8) from the dividend, add it to 14, then carry on: 148 / 40

Going ahead to step 3:
40 can be fit into 148 3 times, resulting in a remainder of 28.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 28 after subtracting 120 from 148.
Include the next digit (9) from the dividend after 28, then repeat: 289 / 40

On to step 4:
If we divide 289 by 40, we get 7 and a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 37.0
Subtracting 280 from 289 leaves us with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 40

Advancing to step 5:
40 goes into 91 2 times with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 372.0
Deduct 80 from 91 and we're left with 11.
Fetch the next digit (0) from the dividend, attach it to 11 and continue: 110 / 40

On to step 6:
When dividing 110 by 40, we get 2 with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 3722.0
If we subtract 80 from 110, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 7:
The number 40 fits into 300 7 times, leaving a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 3722.7
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.

Moving on to step 8:
When dividing 200 by 40, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 3722.75
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:
If we divide 0 by 40, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3722.75
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:
If we divide 0 by 40, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3722.75
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.

In conclusion, the division gives 3722.75 with a balance of 0.0.
