Let's divide 180902 by 39
We're looking to find how many times 39 goes into 180902.

Moving on to step 1:
When dividing 1 by 39, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 39

On to step 2:
If we divide 18 by 39, we get 0 and a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (0) of the dividend behind the 18 and repeat the process: 180 / 39

Moving on to step 3:
180 divided by 39 is 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 156 from 180 to get 24.
Fetch the next digit (9) from the dividend, attach it to 24 and continue: 249 / 39

Step 4:
39 goes into 249 6 times with a remainder of 15.
Put 6 as the next digit of the answer. 
Result so far: 46.0
Deduct 234 from 249 and we're left with 15.
Grab the next digit (0) from the dividend, add it to 15, then carry on: 150 / 39

Step 5:
39 can be fit into 150 3 times, resulting in a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 463.0
Subtract 117 from 150 to get 33.
Include the next digit (2) from the dividend after 33, then repeat: 332 / 39

Let's proceed to step 6:
39 goes into 332 8 times with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 4638.0
Subtract 312 from 332 to 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.

On to step 7:
If we divide 200 by 39, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 4638.5
If we subtract 195 from 200, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
50 divided by 39 is 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 4638.51
If we take 39 away from 50, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 9:
If we divide 110 by 39, we get 2 and a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 4638.512
If we subtract 78 from 110, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
320 divided by 39 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 4638.5128
The remainder is 8 after subtracting 312 from 320.
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 11:
The number 39 fits into 80 2 times, leaving a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 4638.51282
Subtracting 78 from 80 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.

Moving on to step 12:
39 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 4638.51282
If we subtract 0 from 20, 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.

Advancing to step 13:
If we divide 200 by 39, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 4638.5128205
Deduct 195 from 200 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 14:
50 divided by 39 is 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 4638.51282051
Subtracting 39 from 50 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 4638.51282051 with a remainder of 1.1e-08.
