We're dividing 139146 by 26 
Let's see how many times 26 fits into 139146.

Advancing to step 1:
1 divided by 26 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 26

Step 2:
When dividing 13 by 26, we get 0 with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Bring next digit (9) of the dividend behind the 13 and repeat the process: 139 / 26

Moving on to step 3:
The number 26 fits into 139 5 times, leaving a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 130 from 139 leaves us with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 26

Step 4:
26 can be fit into 91 3 times, resulting in a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 53.0
If we take 78 away from 91, we end up with 13.
Take the next digit (4) from the dividend and append it to 13, then repeat: 134 / 26

Going ahead to step 5:
26 goes into 134 5 times with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 535.0
Subtracting 130 from 134 leaves us with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 26

Let's proceed to step 6:
26 goes into 46 1 times with a remainder of 20.
Put 1 as the next digit of the answer. 
Result so far: 5351.0
The remainder is 20 after subtracting 26 from 46.
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:
When dividing 200 by 26, we get 7 with a remainder of 18.
Use 7 as the next digit of our solution. 
Result so far: 5351.7
If we subtract 182 from 200, we 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.

Let's proceed to step 8:
If we divide 180 by 26, we get 6 and a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 5351.76
If we subtract 156 from 180, we 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.

Moving on to step 9:
When dividing 240 by 26, we get 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 5351.769
If we subtract 234 from 240, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
26 goes into 60 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 5351.7692
If we subtract 52 from 60, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
80 divided by 26 is 3 with a remainder of 2.
The next digit of our result is 3. 
Result so far: 5351.76923
Subtract 78 from 80 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
26 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 5351.76923
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
When dividing 200 by 26, we get 7 with a remainder of 18.
The next digit of our result is 7. 
Result so far: 5351.7692307
If we take 182 away from 200, we end up with 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:
The number 26 fits into 180 6 times, leaving a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 5351.76923076
Subtracting 156 from 180 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 5351.76923076, with a leftover of 2.4e-08.
