We look at the division of 43780457 by 75 
We want to figure out the number of times 43780457 can be divided by 75.

Advancing to step 1:
75 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 75

Step 2:
When dividing 43 by 75, we get 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 43, we get 43.
Grab the next digit (7) from the dividend, add it to 43, then carry on: 437 / 75

Going ahead to step 3:
When dividing 437 by 75, we get 5 with a remainder of 62.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 375 from 437 leaves us with 62.
Append the next digit (8) from the dividend to 62 and continue with: 628 / 75

Step 4:
75 goes into 628 8 times with a remainder of 28.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
Subtract 600 from 628 to get 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 75

Let's proceed to step 5:
When dividing 280 by 75, we get 3 with a remainder of 55.
The next digit of our result is 3. 
Result so far: 583.0
The remainder is 55 after subtracting 225 from 280.
Fetch the next digit (4) from the dividend, attach it to 55 and continue: 554 / 75

Step 6:
75 can be fit into 554 7 times, resulting in a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 5837.0
Deduct 525 from 554 and we're left with 29.
Append the next digit (5) from the dividend to 29 and continue with: 295 / 75

On to step 7:
75 can be fit into 295 3 times, resulting in a remainder of 70.
Record the quotient 3 as the next digit in the result. 
Result so far: 58373.0
Subtracting 225 from 295 leaves us with 70.
Grab the next digit (7) from the dividend, add it to 70, then carry on: 707 / 75

On to step 8:
When dividing 707 by 75, we get 9 with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 583739.0
Subtracting 675 from 707 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
When dividing 320 by 75, we get 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 583739.4
The remainder is 20 after subtracting 300 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
When dividing 200 by 75, we get 2 with a remainder of 50.
Write down 2 as next digit of the result. 
Result so far: 583739.42
If we subtract 150 from 200, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 11:
500 divided by 75 is 6 with a remainder of 50.
The number 6 becomes the next digit in our result. 
Result so far: 583739.426
Subtracting 450 from 500 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 12:
When dividing 500 by 75, we get 6 with a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 583739.4266
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 583739.4266 with a remaining 0.0005.
