We're dividing 261638 by 1 
We want to divide 261638 by 1.

Step 1:
The number 1 fits into 2 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 2 from 2, we get 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Let's proceed to step 2:
1 can be fit into 6 6 times, resulting in a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
If we take 6 away from 6, we end up with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

Let's proceed to step 3:
1 goes into 1 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 261.0
Deduct 1 from 1 and we're left with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 1

Advancing to step 4:
The number 1 fits into 6 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 2616.0
If we take 6 away from 6, we end up with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Advancing to step 5:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 26163.0
Subtracting 3 from 3 leaves us with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 1

On to step 6:
8 divided by 1 is 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 261638.0
The remainder is 0 after subtracting 8 from 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 261638.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 261638.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 261638.0 with a remainder of 0.0.
