We divide 77811275 by 31
The aim is to understand the frequency of 31 in 77811275.

Moving on to step 1:
31 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 31

Let's proceed to step 2:
The number 31 fits into 77 2 times, leaving a remainder of 15.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 62 from 77 leaves us with 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 31

Step 3:
If we divide 158 by 31, we get 5 and a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we subtract 155 from 158, we get 3.
Fetch the next digit (1) from the dividend, attach it to 3 and continue: 31 / 31

Going ahead to step 4:
31 goes into 31 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 251.0
If we subtract 31 from 31, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 31

On to step 5:
The number 31 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 2510.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 31

Advancing to step 6:
When dividing 12 by 31, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 25100.0
Subtracting 0 from 12 leaves us with 12.
Grab the next digit (7) from the dividend, add it to 12, then carry on: 127 / 31

Let's proceed to step 7:
31 can be fit into 127 4 times, resulting in a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 251004.0
If we take 124 away from 127, we end up with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 31

Advancing to step 8:
31 goes into 35 1 times with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 2510041.0
The remainder is 4 after subtracting 31 from 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
When dividing 40 by 31, we get 1 with a remainder of 9.
The next digit of our result is 1. 
Result so far: 2510041.1
The remainder is 9 after subtracting 31 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 10:
If we divide 90 by 31, we get 2 and a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 2510041.12
Deduct 62 from 90 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 11:
31 can be fit into 280 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 2510041.129
Deduct 279 from 280 and we're left 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.

Step 12:
If we divide 10 by 31, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 2510041.129
If we take 0 away from 10, we end up 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.

Advancing to step 13:
If we divide 100 by 31, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 2510041.12903
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.

On to step 14:
31 can be fit into 70 2 times, resulting in a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2510041.129032
If we subtract 62 from 70, we 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.

Going ahead to step 15:
When dividing 80 by 31, we get 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 2510041.1290322
The remainder is 18 after subtracting 62 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 2510041.1290322 with a remaining 1.8e-07.
