78566525 divided by 313 
The aim is to understand the frequency of 313 in 78566525.

Let's proceed to step 1:
7 divided by 313 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 313

On to step 2:
313 can be fit into 78 0 times, resulting in a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Fetch the next digit (5) from the dividend, attach it to 78 and continue: 785 / 313

Step 3:
313 goes into 785 2 times with a remainder of 159.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 626 from 785 and we're left with 159.
Include the next digit (6) from the dividend after 159, then repeat: 1596 / 313

Advancing to step 4:
313 can be fit into 1596 5 times, resulting in a remainder of 31.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we take 1565 away from 1596, we end up with 31.
Fetch the next digit (6) from the dividend, attach it to 31 and continue: 316 / 313

On to step 5:
If we divide 316 by 313, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 251.0
If we take 313 away from 316, we end up with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 313

Step 6:
When dividing 35 by 313, we get 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 2510.0
If we take 0 away from 35, we end up with 35.
Include the next digit (2) from the dividend after 35, then repeat: 352 / 313

Let's proceed to step 7:
313 can be fit into 352 1 times, resulting in a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 25101.0
Subtract 313 from 352 to get 39.
Include the next digit (5) from the dividend after 39, then repeat: 395 / 313

On to step 8:
When dividing 395 by 313, we get 1 with a remainder of 82.
Put 1 as the next digit of the answer. 
Result so far: 251011.0
Deduct 313 from 395 and we're left with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Advancing to step 9:
820 divided by 313 is 2 with a remainder of 194.
Use 2 as the next digit of our solution. 
Result so far: 251011.2
Subtracting 626 from 820 leaves us with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 10:
313 goes into 1940 6 times with a remainder of 62.
The next digit of our result is 6. 
Result so far: 251011.26
Deduct 1878 from 1940 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 11:
313 can be fit into 620 1 times, resulting in a remainder of 307.
Use 1 as the next digit of our solution. 
Result so far: 251011.261
If we subtract 313 from 620, we get 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Step 12:
The number 313 fits into 3070 9 times, leaving a remainder of 253.
The next digit of our result is 9. 
Result so far: 251011.2619
If we take 2817 away from 3070, we end up with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Let's proceed to step 13:
313 goes into 2530 8 times with a remainder of 26.
The next digit of our result is 8. 
Result so far: 251011.26198
If we subtract 2504 from 2530, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 14:
313 goes into 260 0 times with a remainder of 260.
The number 0 becomes the next digit in our result. 
Result so far: 251011.26198
Subtracting 0 from 260 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

On to step 15:
The number 313 fits into 2600 8 times, leaving a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 251011.2619808
Subtracting 2504 from 2600 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Advancing to step 16:
313 goes into 960 3 times with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 251011.26198083
If we subtract 939 from 960, 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.

The final outcome is 251011.26198083, with a leftover of 2.1e-08.
