Let's divide 15421782 by 375
We want to figure out the number of times 15421782 can be divided by 375.

Advancing to step 1:
1 divided by 375 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 375

On to step 2:
If we divide 15 by 375, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 15 after subtracting 0 from 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 375

Advancing to step 3:
The number 375 fits into 154 0 times, leaving a remainder of 154.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 154, we get 154.
Take the next digit (2) from the dividend and append it to 154, then repeat: 1542 / 375

Moving on to step 4:
375 can be fit into 1542 4 times, resulting in a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 1500 from 1542 leaves us with 42.
Grab the next digit (1) from the dividend, add it to 42, then carry on: 421 / 375

Moving on to step 5:
375 can be fit into 421 1 times, resulting in a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Subtracting 375 from 421 leaves us with 46.
Include the next digit (7) from the dividend after 46, then repeat: 467 / 375

Step 6:
375 goes into 467 1 times with a remainder of 92.
Record the quotient 1 as the next digit in the result. 
Result so far: 411.0
Deduct 375 from 467 and we're left with 92.
Include the next digit (8) from the dividend after 92, then repeat: 928 / 375

Going ahead to step 7:
928 divided by 375 is 2 with a remainder of 178.
Write down 2 as next digit of the result. 
Result so far: 4112.0
The remainder is 178 after subtracting 750 from 928.
Bring next digit (2) of the dividend behind the 178 and repeat the process: 1782 / 375

Moving on to step 8:
375 goes into 1782 4 times with a remainder of 282.
Put 4 as the next digit of the answer. 
Result so far: 41124.0
The remainder is 282 after subtracting 1500 from 1782.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Let's proceed to step 9:
If we divide 2820 by 375, we get 7 and a remainder of 195.
The number 7 becomes the next digit in our result. 
Result so far: 41124.7
Subtracting 2625 from 2820 leaves us with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 10:
375 goes into 1950 5 times with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 41124.75
If we take 1875 away from 1950, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 11:
375 can be fit into 750 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 41124.752
Deduct 750 from 750 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 12:
If we divide 0 by 375, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 41124.752
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.

Let's proceed to step 13:
375 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 41124.752
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.

Our division results in 41124.752 with a remaining 0.0.
