737813 ÷ 31 
The aim is to understand the frequency of 31 in 737813.

Advancing 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
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 31

Moving on to step 2:
If we divide 73 by 31, we get 2 and a remainder of 11.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 62 away from 73, we end up with 11.
Bring next digit (7) of the dividend behind the 11 and repeat the process: 117 / 31

On to step 3:
31 can be fit into 117 3 times, resulting in a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 23.0
If we subtract 93 from 117, we get 24.
Append the next digit (8) from the dividend to 24 and continue with: 248 / 31

Going ahead to step 4:
31 goes into 248 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 238.0
Deduct 248 from 248 and we're left with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 31

Let's proceed to step 5:
If we divide 1 by 31, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 2380.0
Subtract 0 from 1 to get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 31

Moving on to step 6:
The number 31 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 23800.0
Subtract 0 from 13 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 7:
130 divided by 31 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 23800.4
Subtracting 124 from 130 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 8:
If we divide 60 by 31, we get 1 and a remainder of 29.
The next digit of our result is 1. 
Result so far: 23800.41
If we subtract 31 from 60, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 9:
31 goes into 290 9 times with a remainder of 11.
Record the quotient 9 as the next digit in the result. 
Result so far: 23800.419
Subtract 279 from 290 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 10:
If we divide 110 by 31, we get 3 and a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 23800.4193
If we take 93 away from 110, we end up with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 11:
31 can be fit into 170 5 times, resulting in a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 23800.41935
Subtracting 155 from 170 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 12:
The number 31 fits into 150 4 times, leaving a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 23800.419354
Subtract 124 from 150 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 13:
When dividing 260 by 31, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 23800.4193548
The remainder is 12 after subtracting 248 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 14:
31 goes into 120 3 times with a remainder of 27.
Write down 3 as next digit of the result. 
Result so far: 23800.41935483
If we take 93 away from 120, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Our division results in 23800.41935483 with a remaining 2.7e-08.
