312564 divided by 77 
Our goal is to divide 312564 by 77.

Let's proceed to step 1:
77 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 77

Advancing to step 2:
77 goes into 31 0 times with a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Include the next digit (2) from the dividend after 31, then repeat: 312 / 77

Let's proceed to step 3:
77 goes into 312 4 times with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 308 from 312, we get 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 77

Advancing to step 4:
If we divide 45 by 77, we get 0 and a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 40.0
Subtracting 0 from 45 leaves us with 45.
Grab the next digit (6) from the dividend, add it to 45, then carry on: 456 / 77

Step 5:
456 divided by 77 is 5 with a remainder of 71.
Write down 5 as next digit of the result. 
Result so far: 405.0
Subtract 385 from 456 to get 71.
Bring next digit (4) of the dividend behind the 71 and repeat the process: 714 / 77

Advancing to step 6:
714 divided by 77 is 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 4059.0
Subtracting 693 from 714 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 7:
When dividing 210 by 77, we get 2 with a remainder of 56.
The next digit of our result is 2. 
Result so far: 4059.2
If we take 154 away from 210, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 8:
560 divided by 77 is 7 with a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 4059.27
If we subtract 539 from 560, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 9:
77 can be fit into 210 2 times, resulting in a remainder of 56.
The next digit of our result is 2. 
Result so far: 4059.272
Subtract 154 from 210 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 10:
The number 77 fits into 560 7 times, leaving a remainder of 21.
Put 7 as the next digit of the answer. 
Result so far: 4059.2727
If we subtract 539 from 560, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 11:
The number 77 fits into 210 2 times, leaving a remainder of 56.
The number 2 becomes the next digit in our result. 
Result so far: 4059.27272
If we subtract 154 from 210, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 12:
560 divided by 77 is 7 with a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 4059.272727
If we take 539 away from 560, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 13:
77 goes into 210 2 times with a remainder of 56.
Put 2 as the next digit of the answer. 
Result so far: 4059.2727272
Deduct 154 from 210 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 14:
77 goes into 560 7 times with a remainder of 21.
Record the quotient 7 as the next digit in the result. 
Result so far: 4059.27272727
Subtract 539 from 560 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 4059.27272727 with a remainder of 2.1e-08.
