We look at the division of 166365 by 49 
We want to divide 166365 by 49.

Going ahead to step 1:
The number 49 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 49

Advancing to step 2:
When dividing 16 by 49, we get 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 49

Moving on to step 3:
49 can be fit into 166 3 times, resulting in a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 147 from 166 to get 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 49

Advancing to step 4:
49 can be fit into 193 3 times, resulting in a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 33.0
If we take 147 away from 193, we end up with 46.
Bring next digit (6) of the dividend behind the 46 and repeat the process: 466 / 49

On to step 5:
49 goes into 466 9 times with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 339.0
Subtract 441 from 466 to get 25.
Take the next digit (5) from the dividend and append it to 25, then repeat: 255 / 49

Moving on to step 6:
The number 49 fits into 255 5 times, leaving a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 3395.0
Subtract 245 from 255 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.

Advancing to step 7:
49 goes into 100 2 times with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 3395.2
Subtracting 98 from 100 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
When dividing 20 by 49, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 3395.2
Deduct 0 from 20 and we're left 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:
The number 49 fits into 200 4 times, leaving a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 3395.204
If we take 196 away from 200, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
40 divided by 49 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 3395.204
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
If we divide 400 by 49, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 3395.20408
If we subtract 392 from 400, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
49 can be fit into 80 1 times, resulting in a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 3395.204081
Subtract 49 from 80 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 13:
49 goes into 310 6 times with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 3395.2040816
Subtracting 294 from 310 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
49 goes into 160 3 times with a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 3395.20408163
Deduct 147 from 160 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final outcome is 3395.20408163, with a leftover of 1.3e-08.
