638738 ÷ 26 
Our goal is to divide 638738 by 26.

Step 1:
6 divided by 26 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 26

Going ahead to step 2:
63 divided by 26 is 2 with a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 52 from 63 to get 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 26

Step 3:
26 goes into 118 4 times with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
The remainder is 14 after subtracting 104 from 118.
Bring next digit (7) of the dividend behind the 14 and repeat the process: 147 / 26

Moving on to step 4:
26 can be fit into 147 5 times, resulting in a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 245.0
Subtract 130 from 147 to get 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 26

Going ahead to step 5:
26 goes into 173 6 times with a remainder of 17.
Use 6 as the next digit of our solution. 
Result so far: 2456.0
Subtract 156 from 173 to get 17.
Grab the next digit (8) from the dividend, add it to 17, then carry on: 178 / 26

Going ahead to step 6:
If we divide 178 by 26, we get 6 and a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 24566.0
If we take 156 away from 178, 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.

On to step 7:
26 goes into 220 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 24566.8
If we take 208 away from 220, we end up 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:
26 can be fit into 120 4 times, resulting in a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 24566.84
The remainder is 16 after subtracting 104 from 120.
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.
The next digit of our result is 6. 
Result so far: 24566.846
If we take 156 away from 160, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
When dividing 40 by 26, we get 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 24566.8461
Subtract 26 from 40 to get 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:
If we divide 140 by 26, we get 5 and a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 24566.84615
If we subtract 130 from 140, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
100 divided by 26 is 3 with a remainder of 22.
The next digit of our result is 3. 
Result so far: 24566.846153
Subtract 78 from 100 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 13:
220 divided by 26 is 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 24566.8461538
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:
26 goes into 120 4 times with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 24566.84615384
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.

The final outcome is 24566.84615384, with a leftover of 1.6e-08.
