33826171 divided by 31 
The aim is to understand the frequency of 31 in 33826171.

Let's proceed to step 1:
When dividing 3 by 31, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 31

Step 2:
31 can be fit into 33 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 31 from 33 leaves us with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 31

Moving on to step 3:
The number 31 fits into 28 0 times, leaving a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 28 after subtracting 0 from 28.
Take the next digit (2) from the dividend and append it to 28, then repeat: 282 / 31

Going ahead to step 4:
If we divide 282 by 31, we get 9 and a remainder of 3.
The next digit of our result is 9. 
Result so far: 109.0
If we take 279 away from 282, we end up with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 31

On to step 5:
31 can be fit into 36 1 times, resulting in a remainder of 5.
The next digit of our result is 1. 
Result so far: 1091.0
If we take 31 away from 36, we end up with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 31

On to step 6:
If we divide 51 by 31, we get 1 and a remainder of 20.
Use 1 as the next digit of our solution. 
Result so far: 10911.0
If we take 31 away from 51, we end up with 20.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 31

Step 7:
When dividing 207 by 31, we get 6 with a remainder of 21.
Record the quotient 6 as the next digit in the result. 
Result so far: 109116.0
Deduct 186 from 207 and we're left with 21.
Include the next digit (1) from the dividend after 21, then repeat: 211 / 31

Step 8:
31 goes into 211 6 times with a remainder of 25.
Record the quotient 6 as the next digit in the result. 
Result so far: 1091166.0
Deduct 186 from 211 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
If we divide 250 by 31, we get 8 and a remainder of 2.
The next digit of our result is 8. 
Result so far: 1091166.8
If we take 248 away from 250, we end up 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:
31 goes into 20 0 times with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1091166.8
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
31 goes into 200 6 times with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 1091166.806
Subtract 186 from 200 to 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:
140 divided by 31 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 1091166.8064
If we take 124 away from 140, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 13:
31 goes into 160 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 1091166.80645
The remainder is 5 after subtracting 155 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 14:
When dividing 50 by 31, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1091166.806451
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.

Moving on to step 15:
190 divided by 31 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 1091166.8064516
If we subtract 186 from 190, we get 4.
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 16:
If we divide 40 by 31, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 1091166.80645161
If we subtract 31 from 40, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

In conclusion, the division gives 1091166.80645161 with a balance of 9e-09.
