We look at the division of 32439646 by 837 
The aim is to understand the frequency of 837 in 32439646.

On to step 1:
When dividing 3 by 837, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 837

On to step 2:
If we divide 32 by 837, we get 0 and a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 32 leaves us with 32.
Include the next digit (4) from the dividend after 32, then repeat: 324 / 837

Let's proceed to step 3:
The number 837 fits into 324 0 times, leaving a remainder of 324.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 324 after subtracting 0 from 324.
Bring next digit (3) of the dividend behind the 324 and repeat the process: 3243 / 837

Moving on to step 4:
837 can be fit into 3243 3 times, resulting in a remainder of 732.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 2511 from 3243, we get 732.
Include the next digit (9) from the dividend after 732, then repeat: 7329 / 837

Advancing to step 5:
The number 837 fits into 7329 8 times, leaving a remainder of 633.
Write down 8 as next digit of the result. 
Result so far: 38.0
If we take 6696 away from 7329, we end up with 633.
Include the next digit (6) from the dividend after 633, then repeat: 6336 / 837

Advancing to step 6:
When dividing 6336 by 837, we get 7 with a remainder of 477.
The number 7 becomes the next digit in our result. 
Result so far: 387.0
If we take 5859 away from 6336, we end up with 477.
Append the next digit (4) from the dividend to 477 and continue with: 4774 / 837

Moving on to step 7:
When dividing 4774 by 837, we get 5 with a remainder of 589.
Put 5 as the next digit of the answer. 
Result so far: 3875.0
Subtracting 4185 from 4774 leaves us with 589.
Include the next digit (6) from the dividend after 589, then repeat: 5896 / 837

Going ahead to step 8:
If we divide 5896 by 837, we get 7 and a remainder of 37.
The next digit of our result is 7. 
Result so far: 38757.0
Subtract 5859 from 5896 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 9:
When dividing 370 by 837, we get 0 with a remainder of 370.
Put 0 as the next digit of the answer. 
Result so far: 38757.0
Deduct 0 from 370 and we're left with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 10:
837 goes into 3700 4 times with a remainder of 352.
The number 4 becomes the next digit in our result. 
Result so far: 38757.04
The remainder is 352 after subtracting 3348 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 11:
837 goes into 3520 4 times with a remainder of 172.
Record the quotient 4 as the next digit in the result. 
Result so far: 38757.044
Subtract 3348 from 3520 to get 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The quotient of the division is 38757.044, and the remainder is 0.0172.
