Let's divide 113257 by 3
Let's see how many times 3 fits into 113257.

Going ahead to step 1:
The number 3 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 3

Moving on to step 2:
When dividing 11 by 3, we get 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 9 from 11 leaves us with 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 3

On to step 3:
3 can be fit into 23 7 times, resulting in a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 37.0
Subtract 21 from 23 to get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 3

Let's proceed to step 4:
When dividing 22 by 3, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 377.0
If we take 21 away from 22, 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:
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: 3775.0
Subtract 15 from 15 to get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 3

Advancing to step 6:
If we divide 7 by 3, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 37752.0
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.

On to step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 37752.3
Deduct 9 from 10 and we're left 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.

Moving on to step 8:
3 can be fit into 10 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 37752.33
Deduct 9 from 10 and we're left 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 37752.33, with a leftover of 0.001.
