We look at the division of 639872 by 26 
Our goal is to divide 639872 by 26.

Moving on to step 1:
6 divided by 26 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 26

Let's proceed to step 2:
The number 26 fits into 63 2 times, leaving a remainder of 11.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 52 from 63 leaves us with 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 26

Step 3:
If we divide 119 by 26, we get 4 and a remainder of 15.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
If we subtract 104 from 119, we get 15.
Append the next digit (8) from the dividend to 15 and continue with: 158 / 26

Going ahead to step 4:
26 goes into 158 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 246.0
Subtract 156 from 158 to get 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 26

Moving on to step 5:
If we divide 27 by 26, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 2461.0
Subtract 26 from 27 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 26

Let's proceed to step 6:
The number 26 fits into 12 0 times, leaving a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 24610.0
If we subtract 0 from 12, we 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.

Step 7:
120 divided by 26 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 24610.4
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.

Let's proceed to step 8:
When dividing 160 by 26, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 24610.46
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.

Step 9:
40 divided by 26 is 1 with a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 24610.461
Subtracting 26 from 40 leaves us 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.

Going ahead to step 10:
If we divide 140 by 26, we get 5 and a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 24610.4615
The remainder is 10 after subtracting 130 from 140.
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 11:
The number 26 fits into 100 3 times, leaving a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 24610.46153
If we subtract 78 from 100, we 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.

On to step 12:
When dividing 220 by 26, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 24610.461538
Subtract 208 from 220 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 13:
The number 26 fits into 120 4 times, leaving a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 24610.4615384
If we subtract 104 from 120, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
If we divide 160 by 26, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 24610.46153846
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.

The final result is 24610.46153846 with a remainder of 4e-09.
