We're dividing 83856564 by 507 
The aim is to understand the frequency of 507 in 83856564.

On to step 1:
When dividing 8 by 507, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 507

Advancing to step 2:
If we divide 83 by 507, we get 0 and a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 83, we get 83.
Grab the next digit (8) from the dividend, add it to 83, then carry on: 838 / 507

Advancing to step 3:
When dividing 838 by 507, we get 1 with a remainder of 331.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 507 from 838 leaves us with 331.
Fetch the next digit (5) from the dividend, attach it to 331 and continue: 3315 / 507

Let's proceed to step 4:
3315 divided by 507 is 6 with a remainder of 273.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 3042 from 3315 to get 273.
Fetch the next digit (6) from the dividend, attach it to 273 and continue: 2736 / 507

Advancing to step 5:
507 goes into 2736 5 times with a remainder of 201.
The number 5 becomes the next digit in our result. 
Result so far: 165.0
Deduct 2535 from 2736 and we're left with 201.
Take the next digit (5) from the dividend and append it to 201, then repeat: 2015 / 507

Step 6:
If we divide 2015 by 507, we get 3 and a remainder of 494.
Record the quotient 3 as the next digit in the result. 
Result so far: 1653.0
Subtract 1521 from 2015 to get 494.
Take the next digit (6) from the dividend and append it to 494, then repeat: 4946 / 507

Let's proceed to step 7:
When dividing 4946 by 507, we get 9 with a remainder of 383.
The number 9 becomes the next digit in our result. 
Result so far: 16539.0
Subtracting 4563 from 4946 leaves us with 383.
Include the next digit (4) from the dividend after 383, then repeat: 3834 / 507

Moving on to step 8:
507 can be fit into 3834 7 times, resulting in a remainder of 285.
Record the quotient 7 as the next digit in the result. 
Result so far: 165397.0
If we subtract 3549 from 3834, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Advancing to step 9:
When dividing 2850 by 507, we get 5 with a remainder of 315.
Write down 5 as next digit of the result. 
Result so far: 165397.5
The remainder is 315 after subtracting 2535 from 2850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Going ahead to step 10:
When dividing 3150 by 507, we get 6 with a remainder of 108.
Use 6 as the next digit of our solution. 
Result so far: 165397.56
Subtracting 3042 from 3150 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 11:
1080 divided by 507 is 2 with a remainder of 66.
Write down 2 as next digit of the result. 
Result so far: 165397.562
Subtract 1014 from 1080 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 12:
The number 507 fits into 660 1 times, leaving a remainder of 153.
The number 1 becomes the next digit in our result. 
Result so far: 165397.5621
If we take 507 away from 660, we end up with 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

On to step 13:
1530 divided by 507 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 165397.56213
Subtracting 1521 from 1530 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 14:
90 divided by 507 is 0 with a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 165397.56213
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Moving on to step 15:
If we divide 900 by 507, we get 1 and a remainder of 393.
The number 1 becomes the next digit in our result. 
Result so far: 165397.5621301
Subtract 507 from 900 to get 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Advancing to step 16:
3930 divided by 507 is 7 with a remainder of 381.
Use 7 as the next digit of our solution. 
Result so far: 165397.56213017
If we subtract 3549 from 3930, we get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

In conclusion, the division gives 165397.56213017 with a balance of 3.81e-07.
