Let's divide 76639 by 3
Our goal is to divide 76639 by 3.

On to step 1:
If we divide 7 by 3, we get 2 and a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 1 after subtracting 6 from 7.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 3

Step 2:
16 divided by 3 is 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtract 15 from 16 to get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 3

Let's proceed to step 3:
3 goes into 16 5 times with a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 255.0
Deduct 15 from 16 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 3

Advancing to step 4:
3 goes into 13 4 times with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 2554.0
If we take 12 away from 13, we end up with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 3

Going ahead to step 5:
When dividing 19 by 3, we get 6 with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 25546.0
If we subtract 18 from 19, 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 6:
The number 3 fits into 10 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 25546.3
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 7:
10 divided by 3 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 25546.33
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 25546.33, with a leftover of 0.001.
