We divide 789421 by 26
We're looking to find how many times 26 goes into 789421.

On to step 1:
The number 26 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 26

Advancing to step 2:
26 goes into 78 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 78 from 78, we get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 26

On to step 3:
The number 26 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 30.0
If we subtract 0 from 9, we get 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 26

On to step 4:
If we divide 94 by 26, we get 3 and a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 303.0
If we take 78 away from 94, we end up with 16.
Grab the next digit (2) from the dividend, add it to 16, then carry on: 162 / 26

Advancing to step 5:
26 can be fit into 162 6 times, resulting in a remainder of 6.
The number 6 becomes the next digit in our result. 
Result so far: 3036.0
If we take 156 away from 162, we end up with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 26

Moving on to step 6:
When dividing 61 by 26, we get 2 with a remainder of 9.
Use 2 as the next digit of our solution. 
Result so far: 30362.0
If we take 52 away from 61, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
90 divided by 26 is 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 30362.3
Subtracting 78 from 90 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
120 divided by 26 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 30362.34
If we take 104 away from 120, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
160 divided by 26 is 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 30362.346
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
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: 30362.3461
If we take 26 away from 40, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
26 can be fit into 140 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 30362.34615
Subtracting 130 from 140 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
26 can be fit into 100 3 times, resulting in a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 30362.346153
If we take 78 away from 100, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 13:
26 goes into 220 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 30362.3461538
Deduct 208 from 220 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
If we divide 120 by 26, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 30362.34615384
Subtracting 104 from 120 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 30362.34615384 and a remainder of 1.6e-08.
