We look at the division of 13238902 by 139 
Let's see how many times 139 fits into 13238902.

On to step 1:
The number 139 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 139

Step 2:
139 goes into 13 0 times with a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 139

Advancing to step 3:
The number 139 fits into 132 0 times, leaving a remainder of 132.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 132, we end up with 132.
Take the next digit (3) from the dividend and append it to 132, then repeat: 1323 / 139

Going ahead to step 4:
139 goes into 1323 9 times with a remainder of 72.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 1251 from 1323 to get 72.
Include the next digit (8) from the dividend after 72, then repeat: 728 / 139

Let's proceed to step 5:
If we divide 728 by 139, we get 5 and a remainder of 33.
Write down 5 as next digit of the result. 
Result so far: 95.0
If we subtract 695 from 728, we get 33.
Fetch the next digit (9) from the dividend, attach it to 33 and continue: 339 / 139

Going ahead to step 6:
339 divided by 139 is 2 with a remainder of 61.
Write down 2 as next digit of the result. 
Result so far: 952.0
Subtracting 278 from 339 leaves us with 61.
Take the next digit (0) from the dividend and append it to 61, then repeat: 610 / 139

Going ahead to step 7:
The number 139 fits into 610 4 times, leaving a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 9524.0
The remainder is 54 after subtracting 556 from 610.
Append the next digit (2) from the dividend to 54 and continue with: 542 / 139

Moving on to step 8:
The number 139 fits into 542 3 times, leaving a remainder of 125.
The number 3 becomes the next digit in our result. 
Result so far: 95243.0
Subtract 417 from 542 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

On to step 9:
The number 139 fits into 1250 8 times, leaving a remainder of 138.
The next digit of our result is 8. 
Result so far: 95243.8
If we subtract 1112 from 1250, we get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

On to step 10:
1380 divided by 139 is 9 with a remainder of 129.
The number 9 becomes the next digit in our result. 
Result so far: 95243.89
Subtract 1251 from 1380 to get 129.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1290, and continue the process.

Going ahead to step 11:
139 can be fit into 1290 9 times, resulting in a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 95243.899
If we take 1251 away from 1290, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The quotient of the division is 95243.899, and the remainder is 0.0039.
