We're dividing 83537404 by 837 
The aim is to understand the frequency of 837 in 83537404.

Going ahead to step 1:
8 divided by 837 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 837

Going ahead to step 2:
The number 837 fits into 83 0 times, leaving a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 83 leaves us with 83.
Bring next digit (5) of the dividend behind the 83 and repeat the process: 835 / 837

Let's proceed to step 3:
If we divide 835 by 837, we get 0 and a remainder of 835.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 835 to get 835.
Take the next digit (3) from the dividend and append it to 835, then repeat: 8353 / 837

Moving on to step 4:
If we divide 8353 by 837, we get 9 and a remainder of 820.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 7533 from 8353, we get 820.
Append the next digit (7) from the dividend to 820 and continue with: 8207 / 837

Advancing to step 5:
If we divide 8207 by 837, we get 9 and a remainder of 674.
Put 9 as the next digit of the answer. 
Result so far: 99.0
Deduct 7533 from 8207 and we're left with 674.
Append the next digit (4) from the dividend to 674 and continue with: 6744 / 837

Let's proceed to step 6:
837 can be fit into 6744 8 times, resulting in a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 998.0
If we subtract 6696 from 6744, we get 48.
Include the next digit (0) from the dividend after 48, then repeat: 480 / 837

Going ahead to step 7:
480 divided by 837 is 0 with a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 9980.0
Subtract 0 from 480 to get 480.
Include the next digit (4) from the dividend after 480, then repeat: 4804 / 837

Let's proceed to step 8:
When dividing 4804 by 837, we get 5 with a remainder of 619.
The next digit of our result is 5. 
Result so far: 99805.0
Deduct 4185 from 4804 and we're left with 619.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6190, and continue the process.

Advancing to step 9:
6190 divided by 837 is 7 with a remainder of 331.
Use 7 as the next digit of our solution. 
Result so far: 99805.7
Subtract 5859 from 6190 to get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Moving on to step 10:
837 goes into 3310 3 times with a remainder of 799.
The number 3 becomes the next digit in our result. 
Result so far: 99805.73
If we subtract 2511 from 3310, we get 799.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7990, and continue the process.

Moving on to step 11:
When dividing 7990 by 837, we get 9 with a remainder of 457.
The number 9 becomes the next digit in our result. 
Result so far: 99805.739
The remainder is 457 after subtracting 7533 from 7990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Going ahead to step 12:
837 goes into 4570 5 times with a remainder of 385.
Write down 5 as next digit of the result. 
Result so far: 99805.7395
Subtracting 4185 from 4570 leaves us with 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

On to step 13:
3850 divided by 837 is 4 with a remainder of 502.
Record the quotient 4 as the next digit in the result. 
Result so far: 99805.73954
If we take 3348 away from 3850, we end up with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Let's proceed to step 14:
837 goes into 5020 5 times with a remainder of 835.
The number 5 becomes the next digit in our result. 
Result so far: 99805.739545
If we subtract 4185 from 5020, we get 835.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8350, and continue the process.

Let's proceed to step 15:
8350 divided by 837 is 9 with a remainder of 817.
Use 9 as the next digit of our solution. 
Result so far: 99805.7395459
Subtracting 7533 from 8350 leaves us with 817.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8170, and continue the process.

Step 16:
The number 837 fits into 8170 9 times, leaving a remainder of 637.
Write down 9 as next digit of the result. 
Result so far: 99805.73954599
Subtract 7533 from 8170 to get 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

The final result is 99805.73954599 with a remainder of 6.37e-07.
