77614648 ÷ 31 
The aim is to understand the frequency of 31 in 77614648.

Let's proceed to step 1:
31 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 31

Step 2:
If we divide 77 by 31, we get 2 and a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 15 after subtracting 62 from 77.
Grab the next digit (6) from the dividend, add it to 15, then carry on: 156 / 31

On to step 3:
31 can be fit into 156 5 times, resulting in a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
If we take 155 away from 156, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 31

Step 4:
When dividing 11 by 31, we get 0 with a remainder of 11.
The next digit of our result is 0. 
Result so far: 250.0
The remainder is 11 after subtracting 0 from 11.
Take the next digit (4) from the dividend and append it to 11, then repeat: 114 / 31

Let's proceed to step 5:
If we divide 114 by 31, we get 3 and a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 2503.0
Subtracting 93 from 114 leaves us with 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 31

Step 6:
When dividing 216 by 31, we get 6 with a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 25036.0
Subtracting 186 from 216 leaves us with 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 31

Step 7:
When dividing 304 by 31, we get 9 with a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 250369.0
The remainder is 25 after subtracting 279 from 304.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 31

On to step 8:
The number 31 fits into 258 8 times, leaving a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 2503698.0
If we subtract 248 from 258, we 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.

Going ahead to step 9:
If we divide 100 by 31, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 2503698.3
The remainder is 7 after subtracting 93 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
31 goes into 70 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 2503698.32
Subtract 62 from 70 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 11:
When dividing 80 by 31, we get 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 2503698.322
If we take 62 away from 80, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 2503698.322, and the remainder is 0.0018.
