Let's divide 65289125 by 837
The aim is to understand the frequency of 837 in 65289125.

Let's proceed to step 1:
When dividing 6 by 837, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 837

Moving on to step 2:
The number 837 fits into 65 0 times, leaving a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 65, we end up with 65.
Include the next digit (2) from the dividend after 65, then repeat: 652 / 837

Step 3:
652 divided by 837 is 0 with a remainder of 652.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 652, we get 652.
Fetch the next digit (8) from the dividend, attach it to 652 and continue: 6528 / 837

On to step 4:
837 goes into 6528 7 times with a remainder of 669.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 5859 from 6528 leaves us with 669.
Fetch the next digit (9) from the dividend, attach it to 669 and continue: 6699 / 837

Let's proceed to step 5:
837 can be fit into 6699 8 times, resulting in a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 78.0
Deduct 6696 from 6699 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 837

Advancing to step 6:
31 divided by 837 is 0 with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 780.0
If we take 0 away from 31, we end up with 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 837

Step 7:
312 divided by 837 is 0 with a remainder of 312.
The next digit of our result is 0. 
Result so far: 7800.0
The remainder is 312 after subtracting 0 from 312.
Fetch the next digit (5) from the dividend, attach it to 312 and continue: 3125 / 837

Advancing to step 8:
837 goes into 3125 3 times with a remainder of 614.
Write down 3 as next digit of the result. 
Result so far: 78003.0
If we subtract 2511 from 3125, we get 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Advancing to step 9:
When dividing 6140 by 837, we get 7 with a remainder of 281.
Record the quotient 7 as the next digit in the result. 
Result so far: 78003.7
Deduct 5859 from 6140 and we're left with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Step 10:
If we divide 2810 by 837, we get 3 and a remainder of 299.
Record the quotient 3 as the next digit in the result. 
Result so far: 78003.73
If we take 2511 away from 2810, we end up with 299.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2990, and continue the process.

Moving on to step 11:
If we divide 2990 by 837, we get 3 and a remainder of 479.
Put 3 as the next digit of the answer. 
Result so far: 78003.733
The remainder is 479 after subtracting 2511 from 2990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

The final outcome is 78003.733, with a leftover of 0.0479.
