88407 divided by 31 
The aim is to understand the frequency of 31 in 88407.

On to step 1:
31 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (8) from the dividend after 8, then repeat: 88 / 31

Let's proceed to step 2:
If we divide 88 by 31, we get 2 and a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 62 from 88 to get 26.
Bring next digit (4) of the dividend behind the 26 and repeat the process: 264 / 31

Going ahead to step 3:
When dividing 264 by 31, we get 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
If we take 248 away from 264, we end up with 16.
Fetch the next digit (0) from the dividend, attach it to 16 and continue: 160 / 31

Let's proceed to step 4:
160 divided by 31 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 285.0
Subtract 155 from 160 to get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 31

Advancing to step 5:
If we divide 57 by 31, we get 1 and a remainder of 26.
The next digit of our result is 1. 
Result so far: 2851.0
Subtract 31 from 57 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.

Let's proceed to step 6:
31 goes into 260 8 times with a remainder of 12.
The next digit of our result is 8. 
Result so far: 2851.8
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.

Advancing to step 7:
31 goes into 120 3 times with a remainder of 27.
Record the quotient 3 as the next digit in the result. 
Result so far: 2851.83
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.

Moving on to step 8:
When dividing 270 by 31, we get 8 with a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 2851.838
If we take 248 away from 270, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
The number 31 fits into 220 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 2851.8387
The remainder is 3 after subtracting 217 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 10:
31 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 2851.8387
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
When dividing 300 by 31, we get 9 with a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 2851.838709
Subtract 279 from 300 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 12:
31 can be fit into 210 6 times, resulting in a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 2851.8387096
Deduct 186 from 210 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
31 goes into 240 7 times with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 2851.83870967
If we subtract 217 from 240, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

The quotient of the division is 2851.83870967, and the remainder is 2.3e-08.
