312530 ÷ 77 
The aim is to understand the frequency of 77 in 312530.

Going ahead to step 1:
When dividing 3 by 77, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 77

Step 2:
31 divided by 77 is 0 with a remainder of 31.
Put 0 as the next digit of the answer. 
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

Advancing to step 3:
The number 77 fits into 312 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 308 from 312, we get 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 77

Moving on to step 4:
If we divide 45 by 77, we get 0 and a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Subtracting 0 from 45 leaves us with 45.
Bring next digit (3) of the dividend behind the 45 and repeat the process: 453 / 77

On to step 5:
When dividing 453 by 77, we get 5 with a remainder of 68.
The number 5 becomes the next digit in our result. 
Result so far: 405.0
The remainder is 68 after subtracting 385 from 453.
Fetch the next digit (0) from the dividend, attach it to 68 and continue: 680 / 77

On to step 6:
77 goes into 680 8 times with a remainder of 64.
Put 8 as the next digit of the answer. 
Result so far: 4058.0
If we subtract 616 from 680, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 7:
77 goes into 640 8 times with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 4058.8
If we subtract 616 from 640, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 8:
When dividing 240 by 77, we get 3 with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 4058.83
If we subtract 231 from 240, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
77 goes into 90 1 times with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 4058.831
Subtracting 77 from 90 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 10:
77 goes into 130 1 times with a remainder of 53.
Use 1 as the next digit of our solution. 
Result so far: 4058.8311
Subtract 77 from 130 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

In conclusion, the division gives 4058.8311 with a balance of 0.00053.
