Let's divide 43120868 by 1
Our goal is to divide 43120868 by 1.

Step 1:
If we divide 4 by 1, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 4 from 4 leaves us with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Going ahead to step 2:
When dividing 3 by 1, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
The remainder is 0 after subtracting 3 from 3.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 1

On to step 3:
When dividing 1 by 1, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 431.0
If we subtract 1 from 1, we get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 1

On to step 4:
If we divide 2 by 1, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 4312.0
Subtract 2 from 2 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Going ahead to step 5:
1 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 43120.0
Subtract 0 from 0 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Step 6:
1 can be fit into 8 8 times, resulting in a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 431208.0
Deduct 8 from 8 and we're left with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 1

Advancing to step 7:
1 goes into 6 6 times with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 4312086.0
If we take 6 away from 6, we end up with 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 1

Advancing to step 8:
8 divided by 1 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 43120868.0
Deduct 8 from 8 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.

Let's proceed to step 9:
0 divided by 1 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 43120868.0
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.

Let's proceed to step 10:
If we divide 0 by 1, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 43120868.0
If we take 0 away from 0, 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.

The final result is 43120868.0 with a remainder of 0.0.
