253404 ÷ 77 
We want to figure out the number of times 253404 can be divided by 77.

Moving on to step 1:
77 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 77

On to step 2:
25 divided by 77 is 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Append the next digit (3) from the dividend to 25 and continue with: 253 / 77

Let's proceed to step 3:
The number 77 fits into 253 3 times, leaving a remainder of 22.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 231 from 253 to get 22.
Take the next digit (4) from the dividend and append it to 22, then repeat: 224 / 77

Advancing to step 4:
When dividing 224 by 77, we get 2 with a remainder of 70.
The number 2 becomes the next digit in our result. 
Result so far: 32.0
Subtract 154 from 224 to get 70.
Take the next digit (0) from the dividend and append it to 70, then repeat: 700 / 77

Going ahead to step 5:
The number 77 fits into 700 9 times, leaving a remainder of 7.
The next digit of our result is 9. 
Result so far: 329.0
Subtracting 693 from 700 leaves us with 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 77

Advancing to step 6:
77 can be fit into 74 0 times, resulting in a remainder of 74.
The next digit of our result is 0. 
Result so far: 3290.0
If we take 0 away from 74, we end up with 74.
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 7:
77 can be fit into 740 9 times, resulting in a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 3290.9
Subtract 693 from 740 to 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.

On to step 8:
470 divided by 77 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 3290.96
The remainder is 8 after subtracting 462 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
80 divided by 77 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 3290.961
Subtract 77 from 80 to get 3.
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 10:
The number 77 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 3290.961
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.

On to step 11:
If we divide 300 by 77, we get 3 and a remainder of 69.
Put 3 as the next digit of the answer. 
Result so far: 3290.96103
Deduct 231 from 300 and we're left 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.

On to step 12:
If we divide 690 by 77, we get 8 and a remainder of 74.
Write down 8 as next digit of the result. 
Result so far: 3290.961038
If we subtract 616 from 690, we get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Step 13:
77 can be fit into 740 9 times, resulting in a remainder of 47.
The number 9 becomes the next digit in our result. 
Result so far: 3290.9610389
If we take 693 away from 740, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 14:
The number 77 fits into 470 6 times, leaving a remainder of 8.
The next digit of our result is 6. 
Result so far: 3290.96103896
The remainder is 8 after subtracting 462 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 3290.96103896 with a remaining 8e-09.
