Let's divide 352507 by 3
We're looking to find how many times 3 goes into 352507.

Step 1:
When dividing 3 by 3, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 0 after subtracting 3 from 3.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 3

Advancing to step 2:
If we divide 5 by 3, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 11.0
If we subtract 3 from 5, we get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 3

Advancing to step 3:
When dividing 22 by 3, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 117.0
The remainder is 1 after subtracting 21 from 22.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 3

Advancing to step 4:
The number 3 fits into 15 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 1175.0
If we take 15 away from 15, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 3

Going ahead to step 5:
3 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 11750.0
If we take 0 away from 0, we end up with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 3

Let's proceed to step 6:
The number 3 fits into 7 2 times, leaving a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 117502.0
If we subtract 6 from 7, 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.

Advancing to step 7:
3 goes into 10 3 times with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 117502.3
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 8:
3 goes into 10 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 117502.33
If we take 9 away from 10, we end up 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.

The final outcome is 117502.33, with a leftover of 0.001.
