Let's divide 861970 by 2
Let's see how many times 2 fits into 861970.

Step 1:
The number 2 fits into 8 4 times, leaving a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 8 from 8 leaves us with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 2

Advancing to step 2:
If we divide 6 by 2, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 43.0
If we take 6 away from 6, we end up with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

Advancing to step 3:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 430.0
Subtract 0 from 1 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

On to step 4:
2 goes into 19 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 4309.0
The remainder is 1 after subtracting 18 from 19.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 2

Advancing to step 5:
If we divide 17 by 2, we get 8 and a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 43098.0
Subtract 16 from 17 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 2

Moving on to step 6:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 430985.0
Subtracting 10 from 10 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.

Advancing to step 7:
When dividing 0 by 2, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 430985.0
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.

Advancing to step 8:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 430985.0
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.

In conclusion, the division gives 430985.0 with a balance of 0.0.
