We're dividing 59212789 by 237 
The aim is to understand the frequency of 237 in 59212789.

Step 1:
When dividing 5 by 237, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 237

Let's proceed to step 2:
If we divide 59 by 237, we get 0 and a remainder of 59.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 59, we end up with 59.
Fetch the next digit (2) from the dividend, attach it to 59 and continue: 592 / 237

Advancing to step 3:
When dividing 592 by 237, we get 2 with a remainder of 118.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 474 away from 592, we end up with 118.
Fetch the next digit (1) from the dividend, attach it to 118 and continue: 1181 / 237

Step 4:
237 goes into 1181 4 times with a remainder of 233.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Subtracting 948 from 1181 leaves us with 233.
Grab the next digit (2) from the dividend, add it to 233, then carry on: 2332 / 237

Let's proceed to step 5:
237 can be fit into 2332 9 times, resulting in a remainder of 199.
Use 9 as the next digit of our solution. 
Result so far: 249.0
Subtracting 2133 from 2332 leaves us with 199.
Append the next digit (7) from the dividend to 199 and continue with: 1997 / 237

Going ahead to step 6:
237 can be fit into 1997 8 times, resulting in a remainder of 101.
Use 8 as the next digit of our solution. 
Result so far: 2498.0
Subtracting 1896 from 1997 leaves us with 101.
Take the next digit (8) from the dividend and append it to 101, then repeat: 1018 / 237

Advancing to step 7:
If we divide 1018 by 237, we get 4 and a remainder of 70.
Use 4 as the next digit of our solution. 
Result so far: 24984.0
The remainder is 70 after subtracting 948 from 1018.
Take the next digit (9) from the dividend and append it to 70, then repeat: 709 / 237

Step 8:
237 can be fit into 709 2 times, resulting in a remainder of 235.
Use 2 as the next digit of our solution. 
Result so far: 249842.0
If we subtract 474 from 709, we get 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Going ahead to step 9:
237 can be fit into 2350 9 times, resulting in a remainder of 217.
The number 9 becomes the next digit in our result. 
Result so far: 249842.9
If we take 2133 away from 2350, we end up with 217.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2170, and continue the process.

On to step 10:
2170 divided by 237 is 9 with a remainder of 37.
The number 9 becomes the next digit in our result. 
Result so far: 249842.99
The remainder is 37 after subtracting 2133 from 2170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

The final result is 249842.99 with a remainder of 0.037.
