166048 ÷ 40 
We want to figure out the number of times 166048 can be divided by 40.

Moving on to step 1:
40 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 40

Advancing to step 2:
40 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 40

Advancing to step 3:
When dividing 166 by 40, we get 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 160 from 166 and we're left with 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 40

Moving on to step 4:
40 can be fit into 60 1 times, resulting in a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 41.0
The remainder is 20 after subtracting 40 from 60.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 40

Let's proceed to step 5:
40 goes into 204 5 times with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 415.0
If we subtract 200 from 204, we get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 40

On to step 6:
The number 40 fits into 48 1 times, leaving a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 4151.0
The remainder is 8 after subtracting 40 from 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
When dividing 80 by 40, we get 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 4151.2
Deduct 80 from 80 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.

Moving on to step 8:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 4151.2
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.

Advancing to step 9:
40 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4151.2
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.

Our division results in 4151.2 with a remaining 0.0.
