We're dividing 302166 by 39 
We want to figure out the number of times 302166 can be divided by 39.

Let's proceed to step 1:
If we divide 3 by 39, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 39

Let's proceed to step 2:
39 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 39

Advancing to step 3:
The number 39 fits into 302 7 times, leaving a remainder of 29.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 273 from 302 leaves us with 29.
Grab the next digit (1) from the dividend, add it to 29, then carry on: 291 / 39

Going ahead to step 4:
39 goes into 291 7 times with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Subtract 273 from 291 to get 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 39

Advancing to step 5:
186 divided by 39 is 4 with a remainder of 30.
Put 4 as the next digit of the answer. 
Result so far: 774.0
The remainder is 30 after subtracting 156 from 186.
Bring next digit (6) of the dividend behind the 30 and repeat the process: 306 / 39

Moving on to step 6:
If we divide 306 by 39, we get 7 and a remainder of 33.
The number 7 becomes the next digit in our result. 
Result so far: 7747.0
Subtract 273 from 306 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 7:
The number 39 fits into 330 8 times, leaving a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 7747.8
Subtract 312 from 330 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 8:
39 goes into 180 4 times with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 7747.84
Subtract 156 from 180 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
39 can be fit into 240 6 times, resulting in a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 7747.846
If we take 234 away from 240, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
60 divided by 39 is 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 7747.8461
The remainder is 21 after subtracting 39 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 11:
39 goes into 210 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 7747.84615
Deduct 195 from 210 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 12:
150 divided by 39 is 3 with a remainder of 33.
The next digit of our result is 3. 
Result so far: 7747.846153
Deduct 117 from 150 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 13:
39 can be fit into 330 8 times, resulting in a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 7747.8461538
Subtract 312 from 330 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 14:
39 can be fit into 180 4 times, resulting in a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 7747.84615384
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 7747.84615384 with a remaining 2.4e-08.
