15132440 ÷ 375 
We want to figure out the number of times 15132440 can be divided by 375.

Advancing to step 1:
1 divided by 375 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 375

Step 2:
When dividing 15 by 375, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 375

Let's proceed to step 3:
375 goes into 151 0 times with a remainder of 151.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 151 leaves us with 151.
Include the next digit (3) from the dividend after 151, then repeat: 1513 / 375

Advancing to step 4:
375 goes into 1513 4 times with a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we take 1500 away from 1513, we end up with 13.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 375

Moving on to step 5:
375 can be fit into 132 0 times, resulting in a remainder of 132.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtracting 0 from 132 leaves us with 132.
Append the next digit (4) from the dividend to 132 and continue with: 1324 / 375

Moving on to step 6:
375 goes into 1324 3 times with a remainder of 199.
Put 3 as the next digit of the answer. 
Result so far: 403.0
If we take 1125 away from 1324, we end up with 199.
Append the next digit (4) from the dividend to 199 and continue with: 1994 / 375

Going ahead to step 7:
375 can be fit into 1994 5 times, resulting in a remainder of 119.
Record the quotient 5 as the next digit in the result. 
Result so far: 4035.0
Deduct 1875 from 1994 and we're left with 119.
Include the next digit (0) from the dividend after 119, then repeat: 1190 / 375

Let's proceed to step 8:
If we divide 1190 by 375, we get 3 and a remainder of 65.
The number 3 becomes the next digit in our result. 
Result so far: 40353.0
Subtracting 1125 from 1190 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 9:
650 divided by 375 is 1 with a remainder of 275.
The number 1 becomes the next digit in our result. 
Result so far: 40353.1
If we take 375 away from 650, we end up with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Moving on to step 10:
The number 375 fits into 2750 7 times, leaving a remainder of 125.
Put 7 as the next digit of the answer. 
Result so far: 40353.17
The remainder is 125 after subtracting 2625 from 2750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 11:
The number 375 fits into 1250 3 times, leaving a remainder of 125.
Record the quotient 3 as the next digit in the result. 
Result so far: 40353.173
The remainder is 125 after subtracting 1125 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Moving on to step 12:
When dividing 1250 by 375, we get 3 with a remainder of 125.
Write down 3 as next digit of the result. 
Result so far: 40353.1733
Subtract 1125 from 1250 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Our division results in 40353.1733 with a remaining 0.00125.
