We're dividing 72272156 by 237 
The aim is to understand the frequency of 237 in 72272156.

Step 1:
237 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 237

On to step 2:
The number 237 fits into 72 0 times, leaving a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Take the next digit (2) from the dividend and append it to 72, then repeat: 722 / 237

Moving on to step 3:
237 can be fit into 722 3 times, resulting in a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 711 from 722 leaves us with 11.
Take the next digit (7) from the dividend and append it to 11, then repeat: 117 / 237

Let's proceed to step 4:
The number 237 fits into 117 0 times, leaving a remainder of 117.
The next digit of our result is 0. 
Result so far: 30.0
Subtract 0 from 117 to get 117.
Include the next digit (2) from the dividend after 117, then repeat: 1172 / 237

Going ahead to step 5:
When dividing 1172 by 237, we get 4 with a remainder of 224.
The number 4 becomes the next digit in our result. 
Result so far: 304.0
Subtract 948 from 1172 to get 224.
Fetch the next digit (1) from the dividend, attach it to 224 and continue: 2241 / 237

Moving on to step 6:
237 goes into 2241 9 times with a remainder of 108.
Put 9 as the next digit of the answer. 
Result so far: 3049.0
Subtract 2133 from 2241 to get 108.
Fetch the next digit (5) from the dividend, attach it to 108 and continue: 1085 / 237

Let's proceed to step 7:
If we divide 1085 by 237, we get 4 and a remainder of 137.
Write down 4 as next digit of the result. 
Result so far: 30494.0
Deduct 948 from 1085 and we're left with 137.
Grab the next digit (6) from the dividend, add it to 137, then carry on: 1376 / 237

Going ahead to step 8:
If we divide 1376 by 237, we get 5 and a remainder of 191.
Write down 5 as next digit of the result. 
Result so far: 304945.0
If we subtract 1185 from 1376, we get 191.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1910, and continue the process.

Going ahead to step 9:
If we divide 1910 by 237, we get 8 and a remainder of 14.
Record the quotient 8 as the next digit in the result. 
Result so far: 304945.8
The remainder is 14 after subtracting 1896 from 1910.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
237 goes into 140 0 times with a remainder of 140.
Write down 0 as next digit of the result. 
Result so far: 304945.8
The remainder is 140 after subtracting 0 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 11:
1400 divided by 237 is 5 with a remainder of 215.
The next digit of our result is 5. 
Result so far: 304945.805
Deduct 1185 from 1400 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Step 12:
When dividing 2150 by 237, we get 9 with a remainder of 17.
Use 9 as the next digit of our solution. 
Result so far: 304945.8059
If we take 2133 away from 2150, 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 13:
170 divided by 237 is 0 with a remainder of 170.
Record the quotient 0 as the next digit in the result. 
Result so far: 304945.8059
If we take 0 away from 170, we end up with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Going ahead to step 14:
When dividing 1700 by 237, we get 7 with a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 304945.805907
Subtracting 1659 from 1700 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 15:
If we divide 410 by 237, we get 1 and a remainder of 173.
Put 1 as the next digit of the answer. 
Result so far: 304945.8059071
Deduct 237 from 410 and we're left with 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Going ahead to step 16:
237 goes into 1730 7 times with a remainder of 71.
The next digit of our result is 7. 
Result so far: 304945.80590717
If we take 1659 away from 1730, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The quotient of the division is 304945.80590717, and the remainder is 7.1e-08.
