43369438 ÷ 1 
We're looking to find how many times 1 goes into 43369438.

On to step 1:
When dividing 4 by 1, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 4 from 4 and we're left with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Going ahead to step 2:
1 can be fit into 3 3 times, resulting in a remainder of 0.
The next digit of our result is 3. 
Result so far: 43.0
If we take 3 away from 3, we end up with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Moving on to step 3:
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: 433.0
If we subtract 3 from 3, we get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 1

Let's proceed to step 4:
6 divided by 1 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 4336.0
If we subtract 6 from 6, we get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 1

Moving on to step 5:
1 goes into 9 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 43369.0
If we subtract 9 from 9, we get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 1

On to step 6:
1 goes into 4 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 433694.0
If we take 4 away from 4, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

On to step 7:
3 divided by 1 is 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 4336943.0
Subtract 3 from 3 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 1

Advancing to step 8:
1 can be fit into 8 8 times, resulting in a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 43369438.0
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.

Going ahead to step 9:
If we divide 0 by 1, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 43369438.0
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.

Let's proceed to step 10:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 43369438.0
Deduct 0 from 0 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.

In conclusion, the division gives 43369438.0 with a balance of 0.0.
