We look at the division of 23257 by 77 
Let's see how many times 77 fits into 23257.

Moving on to step 1:
77 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 77

On to step 2:
The number 77 fits into 23 0 times, leaving a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Append the next digit (2) from the dividend to 23 and continue with: 232 / 77

Step 3:
232 divided by 77 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 1 after subtracting 231 from 232.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 77

Going ahead to step 4:
77 goes into 15 0 times with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Subtract 0 from 15 to get 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 77

Moving on to step 5:
If we divide 157 by 77, we get 2 and a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 302.0
The remainder is 3 after subtracting 154 from 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 6:
The number 77 fits into 30 0 times, leaving a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 302.0
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
77 can be fit into 300 3 times, resulting in a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 302.03
If we take 231 away from 300, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Let's proceed to step 8:
The number 77 fits into 690 8 times, leaving a remainder of 74.
Write down 8 as next digit of the result. 
Result so far: 302.038
The remainder is 74 after subtracting 616 from 690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 9:
The number 77 fits into 740 9 times, leaving a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 302.0389
If we subtract 693 from 740, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 10:
When dividing 470 by 77, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 302.03896
Deduct 462 from 470 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
77 goes into 80 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 302.038961
The remainder is 3 after subtracting 77 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 12:
77 can be fit into 30 0 times, resulting in a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 302.038961
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 13:
If we divide 300 by 77, we get 3 and a remainder of 69.
Use 3 as the next digit of our solution. 
Result so far: 302.03896103
If we subtract 231 from 300, we get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

The quotient of the division is 302.03896103, and the remainder is 6.9e-08.
