We divide 237720 by 31
The aim is to understand the frequency of 31 in 237720.

Step 1:
31 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 31

Moving on to step 2:
31 can be fit into 23 0 times, resulting in a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Fetch the next digit (7) from the dividend, attach it to 23 and continue: 237 / 31

Let's proceed to step 3:
If we divide 237 by 31, we get 7 and a remainder of 20.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
The remainder is 20 after subtracting 217 from 237.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 31

Going ahead to step 4:
The number 31 fits into 207 6 times, leaving a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 76.0
The remainder is 21 after subtracting 186 from 207.
Include the next digit (2) from the dividend after 21, then repeat: 212 / 31

Advancing to step 5:
31 can be fit into 212 6 times, resulting in a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 766.0
Subtracting 186 from 212 leaves us with 26.
Take the next digit (0) from the dividend and append it to 26, then repeat: 260 / 31

Advancing to step 6:
260 divided by 31 is 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 7668.0
Deduct 248 from 260 and we're left with 12.
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 7:
31 goes into 120 3 times with a remainder of 27.
Put 3 as the next digit of the answer. 
Result so far: 7668.3
Subtract 93 from 120 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Advancing to step 8:
31 can be fit into 270 8 times, resulting in a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 7668.38
The remainder is 22 after subtracting 248 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 9:
The number 31 fits into 220 7 times, leaving a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 7668.387
Deduct 217 from 220 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 10:
The number 31 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 7668.387
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
The number 31 fits into 300 9 times, leaving a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 7668.38709
If we subtract 279 from 300, we 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.

Step 12:
210 divided by 31 is 6 with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 7668.387096
Subtracting 186 from 210 leaves us 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.

Moving on to step 13:
31 goes into 240 7 times with a remainder of 23.
Record the quotient 7 as the next digit in the result. 
Result so far: 7668.3870967
The remainder is 23 after subtracting 217 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 14:
230 divided by 31 is 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 7668.38709677
Subtracting 217 from 230 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 7668.38709677 and a remainder of 1.3e-08.
