We look at the division of 485640 by 26 
We want to figure out the number of times 485640 can be divided by 26.

On to step 1:
When dividing 4 by 26, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 26

Step 2:
The number 26 fits into 48 1 times, leaving a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 26 from 48, we get 22.
Include the next digit (5) from the dividend after 22, then repeat: 225 / 26

Going ahead to step 3:
If we divide 225 by 26, we get 8 and a remainder of 17.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtract 208 from 225 to get 17.
Grab the next digit (6) from the dividend, add it to 17, then carry on: 176 / 26

Let's proceed to step 4:
26 can be fit into 176 6 times, resulting in a remainder of 20.
Put 6 as the next digit of the answer. 
Result so far: 186.0
Subtract 156 from 176 to get 20.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 26

Advancing to step 5:
The number 26 fits into 204 7 times, leaving a remainder of 22.
Use 7 as the next digit of our solution. 
Result so far: 1867.0
Subtracting 182 from 204 leaves us with 22.
Fetch the next digit (0) from the dividend, attach it to 22 and continue: 220 / 26

Moving on to step 6:
220 divided by 26 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 18678.0
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.

Going ahead to step 7:
When dividing 120 by 26, we get 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 18678.4
Deduct 104 from 120 and we're left 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.

Moving on to step 8:
If we divide 160 by 26, we get 6 and a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 18678.46
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.

Advancing to step 9:
The number 26 fits into 40 1 times, leaving a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 18678.461
Deduct 26 from 40 and we're left 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.

Let's proceed to step 10:
140 divided by 26 is 5 with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 18678.4615
Deduct 130 from 140 and we're left 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.

On to step 11:
26 can be fit into 100 3 times, resulting in a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 18678.46153
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.

Let's proceed to step 12:
If we divide 220 by 26, we get 8 and a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 18678.461538
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.

Advancing to step 13:
120 divided by 26 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 18678.4615384
Deduct 104 from 120 and we're left 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 14:
If we divide 160 by 26, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 18678.46153846
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 18678.46153846 with a remainder of 4e-09.
