We divide 645492 by 77
Our goal is to divide 645492 by 77.

Step 1:
6 divided by 77 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 77

Let's proceed to step 2:
The number 77 fits into 64 0 times, leaving a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Include the next digit (5) from the dividend after 64, then repeat: 645 / 77

Moving on to step 3:
The number 77 fits into 645 8 times, leaving a remainder of 29.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
The remainder is 29 after subtracting 616 from 645.
Include the next digit (4) from the dividend after 29, then repeat: 294 / 77

Moving on to step 4:
294 divided by 77 is 3 with a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 83.0
The remainder is 63 after subtracting 231 from 294.
Include the next digit (9) from the dividend after 63, then repeat: 639 / 77

Advancing to step 5:
If we divide 639 by 77, we get 8 and a remainder of 23.
Use 8 as the next digit of our solution. 
Result so far: 838.0
If we take 616 away from 639, we end up with 23.
Include the next digit (2) from the dividend after 23, then repeat: 232 / 77

On to step 6:
77 goes into 232 3 times with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 8383.0
The remainder is 1 after subtracting 231 from 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
77 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 8383.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
The number 77 fits into 100 1 times, leaving a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 8383.01
If we subtract 77 from 100, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 9:
The number 77 fits into 230 2 times, leaving a remainder of 76.
Use 2 as the next digit of our solution. 
Result so far: 8383.012
Subtracting 154 from 230 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

On to step 10:
The number 77 fits into 760 9 times, leaving a remainder of 67.
The next digit of our result is 9. 
Result so far: 8383.0129
Subtract 693 from 760 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 11:
If we divide 670 by 77, we get 8 and a remainder of 54.
The next digit of our result is 8. 
Result so far: 8383.01298
The remainder is 54 after subtracting 616 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 12:
77 goes into 540 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 8383.012987
Subtracting 539 from 540 leaves us 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.

Advancing to step 13:
10 divided by 77 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 8383.012987
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 14:
77 goes into 100 1 times with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 8383.01298701
If we take 77 away from 100, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

After the division, we end up with 8383.01298701 and a remainder of 2.3e-08.
