139289 ÷ 36 
We want to figure out the number of times 139289 can be divided by 36.

Step 1:
1 divided by 36 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 36

Let's proceed to step 2:
If we divide 13 by 36, we get 0 and a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 36

Going ahead to step 3:
36 can be fit into 139 3 times, resulting in a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 108 from 139 to get 31.
Grab the next digit (2) from the dividend, add it to 31, then carry on: 312 / 36

On to step 4:
36 goes into 312 8 times with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we subtract 288 from 312, we get 24.
Bring next digit (8) of the dividend behind the 24 and repeat the process: 248 / 36

Going ahead to step 5:
36 can be fit into 248 6 times, resulting in a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 386.0
The remainder is 32 after subtracting 216 from 248.
Take the next digit (9) from the dividend and append it to 32, then repeat: 329 / 36

Advancing to step 6:
36 can be fit into 329 9 times, resulting in a remainder of 5.
The next digit of our result is 9. 
Result so far: 3869.0
Subtract 324 from 329 to 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.

Step 7:
50 divided by 36 is 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 3869.1
Subtract 36 from 50 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
The number 36 fits into 140 3 times, leaving a remainder of 32.
The next digit of our result is 3. 
Result so far: 3869.13
Deduct 108 from 140 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
When dividing 320 by 36, we get 8 with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 3869.138
The remainder is 32 after subtracting 288 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
36 goes into 320 8 times with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 3869.1388
If we subtract 288 from 320, 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.

The final result is 3869.1388 with a remainder of 0.00032.
