We look at the division of 6354865 by 237 
The aim is to understand the frequency of 237 in 6354865.

Step 1:
When dividing 6 by 237, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 237

Moving on to step 2:
The number 237 fits into 63 0 times, leaving a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 63 and we're left with 63.
Bring next digit (5) of the dividend behind the 63 and repeat the process: 635 / 237

Advancing to step 3:
When dividing 635 by 237, we get 2 with a remainder of 161.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 474 from 635, we get 161.
Include the next digit (4) from the dividend after 161, then repeat: 1614 / 237

Step 4:
1614 divided by 237 is 6 with a remainder of 192.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
The remainder is 192 after subtracting 1422 from 1614.
Append the next digit (8) from the dividend to 192 and continue with: 1928 / 237

Going ahead to step 5:
1928 divided by 237 is 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 268.0
Subtract 1896 from 1928 to get 32.
Grab the next digit (6) from the dividend, add it to 32, then carry on: 326 / 237

Advancing to step 6:
When dividing 326 by 237, we get 1 with a remainder of 89.
Use 1 as the next digit of our solution. 
Result so far: 2681.0
Deduct 237 from 326 and we're left with 89.
Fetch the next digit (5) from the dividend, attach it to 89 and continue: 895 / 237

On to step 7:
237 goes into 895 3 times with a remainder of 184.
Use 3 as the next digit of our solution. 
Result so far: 26813.0
The remainder is 184 after subtracting 711 from 895.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 8:
1840 divided by 237 is 7 with a remainder of 181.
Record the quotient 7 as the next digit in the result. 
Result so far: 26813.7
Deduct 1659 from 1840 and we're left with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Let's proceed to step 9:
237 goes into 1810 7 times with a remainder of 151.
The next digit of our result is 7. 
Result so far: 26813.77
Subtract 1659 from 1810 to get 151.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1510, and continue the process.

The final outcome is 26813.77, with a leftover of 0.151.
