We look at the division of 377457 by 15 
We want to figure out the number of times 377457 can be divided by 15.

On to step 1:
When dividing 3 by 15, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 15

Moving on to step 2:
When dividing 37 by 15, we get 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 30 from 37 to get 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 15

Let's proceed to step 3:
15 goes into 77 5 times with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtracting 75 from 77 leaves us with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 15

Let's proceed to step 4:
If we divide 24 by 15, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 251.0
Deduct 15 from 24 and we're left with 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 15

Moving on to step 5:
95 divided by 15 is 6 with a remainder of 5.
The number 6 becomes the next digit in our result. 
Result so far: 2516.0
If we subtract 90 from 95, we get 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 15

Moving on to step 6:
57 divided by 15 is 3 with a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 25163.0
The remainder is 12 after subtracting 45 from 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
120 divided by 15 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 25163.8
If we take 120 away from 120, 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.

Step 8:
When dividing 0 by 15, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 25163.8
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 9:
If we divide 0 by 15, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 25163.8
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.

In conclusion, the division gives 25163.8 with a balance of 0.0.
