We divide 72581131 by 237
The aim is to understand the frequency of 237 in 72581131.

On to step 1:
When dividing 7 by 237, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 237

On to step 2:
When dividing 72 by 237, we get 0 with a remainder of 72.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Include the next digit (5) from the dividend after 72, then repeat: 725 / 237

On to step 3:
If we divide 725 by 237, we get 3 and a remainder of 14.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 711 from 725 leaves us with 14.
Append the next digit (8) from the dividend to 14 and continue with: 148 / 237

On to step 4:
If we divide 148 by 237, we get 0 and a remainder of 148.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Subtract 0 from 148 to get 148.
Grab the next digit (1) from the dividend, add it to 148, then carry on: 1481 / 237

On to step 5:
If we divide 1481 by 237, we get 6 and a remainder of 59.
Use 6 as the next digit of our solution. 
Result so far: 306.0
Deduct 1422 from 1481 and we're left with 59.
Fetch the next digit (1) from the dividend, attach it to 59 and continue: 591 / 237

Advancing to step 6:
237 can be fit into 591 2 times, resulting in a remainder of 117.
The number 2 becomes the next digit in our result. 
Result so far: 3062.0
Subtracting 474 from 591 leaves us with 117.
Append the next digit (3) from the dividend to 117 and continue with: 1173 / 237

Step 7:
When dividing 1173 by 237, we get 4 with a remainder of 225.
Put 4 as the next digit of the answer. 
Result so far: 30624.0
If we subtract 948 from 1173, we get 225.
Grab the next digit (1) from the dividend, add it to 225, then carry on: 2251 / 237

On to step 8:
237 can be fit into 2251 9 times, resulting in a remainder of 118.
Put 9 as the next digit of the answer. 
Result so far: 306249.0
Subtract 2133 from 2251 to get 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Going ahead to step 9:
237 goes into 1180 4 times with a remainder of 232.
Use 4 as the next digit of our solution. 
Result so far: 306249.4
Subtract 948 from 1180 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 10:
The number 237 fits into 2320 9 times, leaving a remainder of 187.
Write down 9 as next digit of the result. 
Result so far: 306249.49
Deduct 2133 from 2320 and we're left with 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 11:
237 can be fit into 1870 7 times, resulting in a remainder of 211.
Put 7 as the next digit of the answer. 
Result so far: 306249.497
Deduct 1659 from 1870 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

On to step 12:
If we divide 2110 by 237, we get 8 and a remainder of 214.
Use 8 as the next digit of our solution. 
Result so far: 306249.4978
Subtract 1896 from 2110 to get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Moving on to step 13:
The number 237 fits into 2140 9 times, leaving a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 306249.49789
Deduct 2133 from 2140 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 14:
The number 237 fits into 70 0 times, leaving a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 306249.49789
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 15:
If we divide 700 by 237, we get 2 and a remainder of 226.
Use 2 as the next digit of our solution. 
Result so far: 306249.4978902
The remainder is 226 after subtracting 474 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 16:
The number 237 fits into 2260 9 times, leaving a remainder of 127.
The number 9 becomes the next digit in our result. 
Result so far: 306249.49789029
The remainder is 127 after subtracting 2133 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

The final result is 306249.49789029 with a remainder of 1.27e-07.
