31013100 divided by 931 
The aim is to understand the frequency of 931 in 31013100.

Let's proceed to step 1:
931 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 931

Step 2:
931 can be fit into 31 0 times, resulting in a remainder of 31.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Include the next digit (0) from the dividend after 31, then repeat: 310 / 931

On to step 3:
931 goes into 310 0 times with a remainder of 310.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 310, we get 310.
Include the next digit (1) from the dividend after 310, then repeat: 3101 / 931

On to step 4:
931 goes into 3101 3 times with a remainder of 308.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 308 after subtracting 2793 from 3101.
Grab the next digit (3) from the dividend, add it to 308, then carry on: 3083 / 931

Going ahead to step 5:
931 goes into 3083 3 times with a remainder of 290.
Write down 3 as next digit of the result. 
Result so far: 33.0
The remainder is 290 after subtracting 2793 from 3083.
Bring next digit (1) of the dividend behind the 290 and repeat the process: 2901 / 931

Advancing to step 6:
2901 divided by 931 is 3 with a remainder of 108.
Write down 3 as next digit of the result. 
Result so far: 333.0
If we take 2793 away from 2901, we end up with 108.
Grab the next digit (0) from the dividend, add it to 108, then carry on: 1080 / 931

Moving on to step 7:
1080 divided by 931 is 1 with a remainder of 149.
The next digit of our result is 1. 
Result so far: 3331.0
Subtract 931 from 1080 to get 149.
Fetch the next digit (0) from the dividend, attach it to 149 and continue: 1490 / 931

Step 8:
When dividing 1490 by 931, we get 1 with a remainder of 559.
Record the quotient 1 as the next digit in the result. 
Result so far: 33311.0
Subtract 931 from 1490 to get 559.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5590, and continue the process.

Let's proceed to step 9:
931 can be fit into 5590 6 times, resulting in a remainder of 4.
The next digit of our result is 6. 
Result so far: 33311.6
Subtract 5586 from 5590 to 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.

Step 10:
When dividing 40 by 931, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 33311.6
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 11:
931 can be fit into 400 0 times, resulting in a remainder of 400.
Record the quotient 0 as the next digit in the result. 
Result so far: 33311.6
Deduct 0 from 400 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Our division results in 33311.6 with a remaining 0.04.
