We look at the division of 83268992 by 507 
The aim is to understand the frequency of 507 in 83268992.

Advancing to step 1:
The number 507 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (3) from the dividend, add it to 8, then carry on: 83 / 507

Step 2:
When dividing 83 by 507, we get 0 with a remainder of 83.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Append the next digit (2) from the dividend to 83 and continue with: 832 / 507

On to step 3:
The number 507 fits into 832 1 times, leaving a remainder of 325.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 507 from 832 and we're left with 325.
Grab the next digit (6) from the dividend, add it to 325, then carry on: 3256 / 507

Step 4:
If we divide 3256 by 507, we get 6 and a remainder of 214.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we subtract 3042 from 3256, we get 214.
Fetch the next digit (8) from the dividend, attach it to 214 and continue: 2148 / 507

Going ahead to step 5:
2148 divided by 507 is 4 with a remainder of 120.
Put 4 as the next digit of the answer. 
Result so far: 164.0
If we subtract 2028 from 2148, we get 120.
Include the next digit (9) from the dividend after 120, then repeat: 1209 / 507

Moving on to step 6:
If we divide 1209 by 507, we get 2 and a remainder of 195.
Record the quotient 2 as the next digit in the result. 
Result so far: 1642.0
Deduct 1014 from 1209 and we're left with 195.
Bring next digit (9) of the dividend behind the 195 and repeat the process: 1959 / 507

Going ahead to step 7:
When dividing 1959 by 507, we get 3 with a remainder of 438.
Use 3 as the next digit of our solution. 
Result so far: 16423.0
If we subtract 1521 from 1959, we get 438.
Bring next digit (2) of the dividend behind the 438 and repeat the process: 4382 / 507

Let's proceed to step 8:
The number 507 fits into 4382 8 times, leaving a remainder of 326.
Write down 8 as next digit of the result. 
Result so far: 164238.0
The remainder is 326 after subtracting 4056 from 4382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Let's proceed to step 9:
507 goes into 3260 6 times with a remainder of 218.
Use 6 as the next digit of our solution. 
Result so far: 164238.6
Subtracting 3042 from 3260 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Moving on to step 10:
If we divide 2180 by 507, we get 4 and a remainder of 152.
Put 4 as the next digit of the answer. 
Result so far: 164238.64
Subtract 2028 from 2180 to get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Moving on to step 11:
The number 507 fits into 1520 2 times, leaving a remainder of 506.
Record the quotient 2 as the next digit in the result. 
Result so far: 164238.642
Subtracting 1014 from 1520 leaves us with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Let's proceed to step 12:
The number 507 fits into 5060 9 times, leaving a remainder of 497.
The number 9 becomes the next digit in our result. 
Result so far: 164238.6429
Subtracting 4563 from 5060 leaves us with 497.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4970, and continue the process.

Moving on to step 13:
The number 507 fits into 4970 9 times, leaving a remainder of 407.
Record the quotient 9 as the next digit in the result. 
Result so far: 164238.64299
The remainder is 407 after subtracting 4563 from 4970.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4070, and continue the process.

After the division, we end up with 164238.64299 and a remainder of 0.000407.
