We're dividing 407309 by 26 
We want to divide 407309 by 26.

Let's proceed to step 1:
26 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 26

Moving on to step 2:
26 can be fit into 40 1 times, resulting in a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 26 away from 40, we end up with 14.
Grab the next digit (7) from the dividend, add it to 14, then carry on: 147 / 26

Advancing to step 3:
When dividing 147 by 26, we get 5 with a remainder of 17.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 130 away from 147, we end up with 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 26

Advancing to step 4:
26 can be fit into 173 6 times, resulting in a remainder of 17.
The number 6 becomes the next digit in our result. 
Result so far: 156.0
Deduct 156 from 173 and we're left with 17.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 26

Step 5:
26 can be fit into 170 6 times, resulting in a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 1566.0
Deduct 156 from 170 and we're left with 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 26

Moving on to step 6:
149 divided by 26 is 5 with a remainder of 19.
The next digit of our result is 5. 
Result so far: 15665.0
If we take 130 away from 149, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 7:
190 divided by 26 is 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 15665.7
Subtract 182 from 190 to 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.

Advancing to step 8:
The number 26 fits into 80 3 times, leaving a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 15665.73
The remainder is 2 after subtracting 78 from 80.
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 9:
26 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 15665.73
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 10:
The number 26 fits into 200 7 times, leaving a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 15665.7307
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.

Advancing to step 11:
26 can be fit into 180 6 times, resulting in a remainder of 24.
Use 6 as the next digit of our solution. 
Result so far: 15665.73076
If we take 156 away from 180, we end up 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.

Step 12:
26 can be fit into 240 9 times, resulting in a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 15665.730769
Subtract 234 from 240 to 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.

Moving on to step 13:
26 goes into 60 2 times with a remainder of 8.
The next digit of our result is 2. 
Result so far: 15665.7307692
Subtracting 52 from 60 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
26 can be fit into 80 3 times, resulting in a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 15665.73076923
Deduct 78 from 80 and we're left 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.

Our division results in 15665.73076923 with a remaining 2e-09.
