We look at the division of 139404 by 88 
Let's see how many times 88 fits into 139404.

Let's proceed to step 1:
When dividing 1 by 88, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 88

Moving on to step 2:
88 can be fit into 13 0 times, resulting in a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Grab the next digit (9) from the dividend, add it to 13, then carry on: 139 / 88

Step 3:
88 goes into 139 1 times with a remainder of 51.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 88 away from 139, we end up with 51.
Append the next digit (4) from the dividend to 51 and continue with: 514 / 88

Let's proceed to step 4:
88 can be fit into 514 5 times, resulting in a remainder of 74.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 440 from 514 leaves us with 74.
Fetch the next digit (0) from the dividend, attach it to 74 and continue: 740 / 88

Advancing to step 5:
If we divide 740 by 88, we get 8 and a remainder of 36.
The next digit of our result is 8. 
Result so far: 158.0
Subtracting 704 from 740 leaves us with 36.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 88

Advancing to step 6:
When dividing 364 by 88, we get 4 with a remainder of 12.
Put 4 as the next digit of the answer. 
Result so far: 1584.0
Subtract 352 from 364 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
120 divided by 88 is 1 with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 1584.1
Subtract 88 from 120 to 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.

On to step 8:
88 goes into 320 3 times with a remainder of 56.
The next digit of our result is 3. 
Result so far: 1584.13
The remainder is 56 after subtracting 264 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 9:
88 can be fit into 560 6 times, resulting in a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 1584.136
If we take 528 away from 560, we end up 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.

Let's proceed to step 10:
88 can be fit into 320 3 times, resulting in a remainder of 56.
The next digit of our result is 3. 
Result so far: 1584.1363
Deduct 264 from 320 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 11:
560 divided by 88 is 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 1584.13636
The remainder is 32 after subtracting 528 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 12:
When dividing 320 by 88, we get 3 with a remainder of 56.
The next digit of our result is 3. 
Result so far: 1584.136363
If we subtract 264 from 320, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 13:
The number 88 fits into 560 6 times, leaving a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 1584.1363636
Subtracting 528 from 560 leaves us 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.

Advancing to step 14:
88 goes into 320 3 times with a remainder of 56.
The number 3 becomes the next digit in our result. 
Result so far: 1584.13636363
If we subtract 264 from 320, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The final outcome is 1584.13636363, with a leftover of 5.6e-08.
