971621 divided by 2 
Let's see how many times 2 fits into 971621.

Going ahead to step 1:
2 goes into 9 4 times with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Deduct 8 from 9 and we're left with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 2

Advancing to step 2:
2 goes into 17 8 times with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
The remainder is 1 after subtracting 16 from 17.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

Step 3:
2 can be fit into 11 5 times, resulting in a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 485.0
Subtract 10 from 11 to get 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 2

Let's proceed to step 4:
When dividing 16 by 2, we get 8 with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 4858.0
The remainder is 0 after subtracting 16 from 16.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 2

Step 5:
If we divide 2 by 2, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 48581.0
If we take 2 away from 2, we end up with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 2

Step 6:
1 divided by 2 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 485810.0
If we take 0 away from 1, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 485810.5
Deduct 10 from 10 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 485810.5
Subtracting 0 from 0 leaves us with 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 9:
When dividing 0 by 2, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 485810.5
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 outcome is 485810.5, with a leftover of 0.0.
