We look at the division of 76514523 by 237 
The aim is to understand the frequency of 237 in 76514523.

On to step 1:
237 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (6) of the dividend behind the 7 and repeat the process: 76 / 237

Going ahead to step 2:
If we divide 76 by 237, we get 0 and a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 76, we end up with 76.
Include the next digit (5) from the dividend after 76, then repeat: 765 / 237

On to step 3:
The number 237 fits into 765 3 times, leaving a remainder of 54.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 711 away from 765, we end up with 54.
Grab the next digit (1) from the dividend, add it to 54, then carry on: 541 / 237

Going ahead to step 4:
The number 237 fits into 541 2 times, leaving a remainder of 67.
The next digit of our result is 2. 
Result so far: 32.0
Subtract 474 from 541 to get 67.
Include the next digit (4) from the dividend after 67, then repeat: 674 / 237

On to step 5:
237 goes into 674 2 times with a remainder of 200.
Use 2 as the next digit of our solution. 
Result so far: 322.0
If we subtract 474 from 674, we get 200.
Fetch the next digit (5) from the dividend, attach it to 200 and continue: 2005 / 237

Let's proceed to step 6:
237 can be fit into 2005 8 times, resulting in a remainder of 109.
The next digit of our result is 8. 
Result so far: 3228.0
If we subtract 1896 from 2005, we get 109.
Fetch the next digit (2) from the dividend, attach it to 109 and continue: 1092 / 237

Going ahead to step 7:
If we divide 1092 by 237, we get 4 and a remainder of 144.
Put 4 as the next digit of the answer. 
Result so far: 32284.0
Subtract 948 from 1092 to get 144.
Grab the next digit (3) from the dividend, add it to 144, then carry on: 1443 / 237

Moving on to step 8:
1443 divided by 237 is 6 with a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 322846.0
Subtract 1422 from 1443 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.

On to step 9:
When dividing 210 by 237, we get 0 with a remainder of 210.
Put 0 as the next digit of the answer. 
Result so far: 322846.0
If we take 0 away from 210, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Advancing to step 10:
When dividing 2100 by 237, we get 8 with a remainder of 204.
Record the quotient 8 as the next digit in the result. 
Result so far: 322846.08
Subtracting 1896 from 2100 leaves us with 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Going ahead to step 11:
237 can be fit into 2040 8 times, resulting in a remainder of 144.
Use 8 as the next digit of our solution. 
Result so far: 322846.088
The remainder is 144 after subtracting 1896 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Our division results in 322846.088 with a remaining 0.0144.
