We look at the division of 525157 by 3 
Let's see how many times 3 fits into 525157.

Advancing to step 1:
When dividing 5 by 3, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 3 from 5 leaves us with 2.
Fetch the next digit (2) from the dividend, attach it to 2 and continue: 22 / 3

Let's proceed to step 2:
3 can be fit into 22 7 times, resulting in a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we subtract 21 from 22, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 3

Advancing to step 3:
If we divide 15 by 3, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 175.0
The remainder is 0 after subtracting 15 from 15.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 3

Step 4:
3 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 1750.0
If we take 0 away from 1, we end up with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 3

Going ahead to step 5:
15 divided by 3 is 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 17505.0
Deduct 15 from 15 and we're left with 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 3

Advancing to step 6:
If we divide 7 by 3, we get 2 and a remainder of 1.
The next digit of our result is 2. 
Result so far: 175052.0
Subtract 6 from 7 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
10 divided by 3 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 175052.3
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 175052.33
If we subtract 9 from 10, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 175052.33, with a leftover of 0.001.
