We look at the division of 601857 by 15 
We want to divide 601857 by 15.

Let's proceed to step 1:
The number 15 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 15

Let's proceed to step 2:
15 goes into 60 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 60 from 60, we get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 15

Advancing to step 3:
If we divide 1 by 15, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtract 0 from 1 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 15

Going ahead to step 4:
If we divide 18 by 15, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 401.0
Subtracting 15 from 18 leaves us with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 15

Advancing to step 5:
35 divided by 15 is 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 4012.0
The remainder is 5 after subtracting 30 from 35.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 15

Let's proceed to step 6:
15 can be fit into 57 3 times, resulting in a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 40123.0
Deduct 45 from 57 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to 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: 40123.8
Subtracting 120 from 120 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.

On to step 8:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 40123.8
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 9:
If we divide 0 by 15, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 40123.8
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.

Our division results in 40123.8 with a remaining 0.0.
