We divide 85801972 by 2
Let's see how many times 2 fits into 85801972.

Moving on to step 1:
The number 2 fits into 8 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 8 from 8 and we're left with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 2

Going ahead to step 2:
5 divided by 2 is 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 42.0
Subtract 4 from 5 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 2

Going ahead to step 3:
When dividing 18 by 2, we get 9 with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 429.0
If we subtract 18 from 18, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 2

Step 4:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4290.0
If we take 0 away from 0, we end up with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 2

Advancing to step 5:
2 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 42900.0
If we subtract 0 from 1, we get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

On to step 6:
2 can be fit into 19 9 times, resulting in a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 429009.0
If we take 18 away from 19, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 2

Let's proceed to step 7:
2 can be fit into 17 8 times, resulting in a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 4290098.0
If we take 16 away from 17, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 2

Moving on to step 8:
When dividing 12 by 2, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 42900986.0
If we take 12 away from 12, we end up 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 9:
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: 42900986.0
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.

On to step 10:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 42900986.0
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.

In conclusion, the division gives 42900986.0 with a balance of 0.0.
