49665249 divided by 31 
The aim is to understand the frequency of 31 in 49665249.

Step 1:
The number 31 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 31

Moving on to step 2:
31 can be fit into 49 1 times, resulting in a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 31 away from 49, we end up with 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 31

Step 3:
31 can be fit into 186 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 16.0
Subtracting 186 from 186 leaves us with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 31

Step 4:
31 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 160.0
If we take 0 away from 6, we end up with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 31

Advancing to step 5:
When dividing 65 by 31, we get 2 with a remainder of 3.
The next digit of our result is 2. 
Result so far: 1602.0
If we subtract 62 from 65, we get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 31

Let's proceed to step 6:
When dividing 32 by 31, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 16021.0
The remainder is 1 after subtracting 31 from 32.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 31

On to step 7:
31 goes into 14 0 times with a remainder of 14.
The next digit of our result is 0. 
Result so far: 160210.0
The remainder is 14 after subtracting 0 from 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 31

Moving on to step 8:
The number 31 fits into 149 4 times, leaving a remainder of 25.
The number 4 becomes the next digit in our result. 
Result so far: 1602104.0
Subtract 124 from 149 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
250 divided by 31 is 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 1602104.8
Deduct 248 from 250 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 10:
When dividing 20 by 31, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 1602104.8
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
The number 31 fits into 200 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 1602104.806
If we subtract 186 from 200, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 12:
When dividing 140 by 31, we get 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 1602104.8064
If we subtract 124 from 140, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
If we divide 160 by 31, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 1602104.80645
Deduct 155 from 160 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 14:
31 can be fit into 50 1 times, resulting in a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1602104.806451
If we take 31 away from 50, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 15:
31 goes into 190 6 times with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 1602104.8064516
If we take 186 away from 190, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 16:
If we divide 40 by 31, we get 1 and a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1602104.80645161
If we take 31 away from 40, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

After the division, we end up with 1602104.80645161 and a remainder of 9e-09.
