We divide 10163970 by 2
We're looking to find how many times 2 goes into 10163970.

Advancing to step 1:
If we divide 1 by 2, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 2

On to step 2:
If we divide 10 by 2, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 10 from 10 and we're left with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

Step 3:
If we divide 1 by 2, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
If we subtract 0 from 1, we get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 2

Going ahead to step 4:
The number 2 fits into 16 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 508.0
If we subtract 16 from 16, we get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 2

Advancing to step 5:
The number 2 fits into 3 1 times, leaving a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 5081.0
If we take 2 away from 3, we end up with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 2

Going ahead to step 6:
2 goes into 19 9 times with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 50819.0
Deduct 18 from 19 and we're left with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 2

Let's proceed to step 7:
2 goes into 17 8 times with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 508198.0
If we take 16 away from 17, we end up with 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 2

Advancing to step 8:
When dividing 10 by 2, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5081985.0
The remainder is 0 after subtracting 10 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 9:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 5081985.0
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.

Going ahead to step 10:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5081985.0
Subtract 0 from 0 to 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 quotient of the division is 5081985.0, and the remainder is 0.0.
