78149761 ÷ 310 
The aim is to understand the frequency of 310 in 78149761.

Let's proceed to step 1:
If we divide 7 by 310, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 310

Advancing to step 2:
If we divide 78 by 310, we get 0 and a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Fetch the next digit (1) from the dividend, attach it to 78 and continue: 781 / 310

Advancing to step 3:
The number 310 fits into 781 2 times, leaving a remainder of 161.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 620 from 781 leaves us with 161.
Take the next digit (4) from the dividend and append it to 161, then repeat: 1614 / 310

Moving on to step 4:
When dividing 1614 by 310, we get 5 with a remainder of 64.
The next digit of our result is 5. 
Result so far: 25.0
Subtracting 1550 from 1614 leaves us with 64.
Append the next digit (9) from the dividend to 64 and continue with: 649 / 310

Going ahead to step 5:
The number 310 fits into 649 2 times, leaving a remainder of 29.
Use 2 as the next digit of our solution. 
Result so far: 252.0
Subtracting 620 from 649 leaves us with 29.
Include the next digit (7) from the dividend after 29, then repeat: 297 / 310

Advancing to step 6:
310 can be fit into 297 0 times, resulting in a remainder of 297.
Use 0 as the next digit of our solution. 
Result so far: 2520.0
Subtract 0 from 297 to get 297.
Grab the next digit (6) from the dividend, add it to 297, then carry on: 2976 / 310

On to step 7:
310 can be fit into 2976 9 times, resulting in a remainder of 186.
Write down 9 as next digit of the result. 
Result so far: 25209.0
Subtracting 2790 from 2976 leaves us with 186.
Grab the next digit (1) from the dividend, add it to 186, then carry on: 1861 / 310

On to step 8:
310 can be fit into 1861 6 times, resulting in a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 252096.0
Subtracting 1860 from 1861 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.

Going ahead to step 9:
When dividing 10 by 310, we get 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 252096.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 10:
310 goes into 100 0 times with a remainder of 100.
Record the quotient 0 as the next digit in the result. 
Result so far: 252096.0
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

After the division, we end up with 252096.0 and a remainder of 0.1.
