We divide 83397887 by 506
The aim is to understand the frequency of 506 in 83397887.

Let's proceed to step 1:
506 goes into 8 0 times 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.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 506

Let's proceed to step 2:
When dividing 83 by 506, we get 0 with a remainder of 83.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Fetch the next digit (3) from the dividend, attach it to 83 and continue: 833 / 506

Step 3:
When dividing 833 by 506, we get 1 with a remainder of 327.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 327 after subtracting 506 from 833.
Take the next digit (9) from the dividend and append it to 327, then repeat: 3279 / 506

Step 4:
506 goes into 3279 6 times with a remainder of 243.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 3036 away from 3279, we end up with 243.
Bring next digit (7) of the dividend behind the 243 and repeat the process: 2437 / 506

Moving on to step 5:
If we divide 2437 by 506, we get 4 and a remainder of 413.
The next digit of our result is 4. 
Result so far: 164.0
The remainder is 413 after subtracting 2024 from 2437.
Take the next digit (8) from the dividend and append it to 413, then repeat: 4138 / 506

Going ahead to step 6:
When dividing 4138 by 506, we get 8 with a remainder of 90.
Record the quotient 8 as the next digit in the result. 
Result so far: 1648.0
The remainder is 90 after subtracting 4048 from 4138.
Grab the next digit (8) from the dividend, add it to 90, then carry on: 908 / 506

Going ahead to step 7:
The number 506 fits into 908 1 times, leaving a remainder of 402.
The next digit of our result is 1. 
Result so far: 16481.0
If we subtract 506 from 908, we get 402.
Bring next digit (7) of the dividend behind the 402 and repeat the process: 4027 / 506

Step 8:
If we divide 4027 by 506, we get 7 and a remainder of 485.
The next digit of our result is 7. 
Result so far: 164817.0
The remainder is 485 after subtracting 3542 from 4027.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Moving on to step 9:
506 can be fit into 4850 9 times, resulting in a remainder of 296.
Record the quotient 9 as the next digit in the result. 
Result so far: 164817.9
If we take 4554 away from 4850, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 10:
When dividing 2960 by 506, we get 5 with a remainder of 430.
Use 5 as the next digit of our solution. 
Result so far: 164817.95
Subtract 2530 from 2960 to get 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Step 11:
4300 divided by 506 is 8 with a remainder of 252.
Record the quotient 8 as the next digit in the result. 
Result so far: 164817.958
Subtract 4048 from 4300 to get 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 12:
The number 506 fits into 2520 4 times, leaving a remainder of 496.
Record the quotient 4 as the next digit in the result. 
Result so far: 164817.9584
If we subtract 2024 from 2520, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Let's proceed to step 13:
When dividing 4960 by 506, we get 9 with a remainder of 406.
The next digit of our result is 9. 
Result so far: 164817.95849
Subtract 4554 from 4960 to get 406.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Going ahead to step 14:
When dividing 4060 by 506, we get 8 with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 164817.958498
If we subtract 4048 from 4060, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 15:
506 goes into 120 0 times with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 164817.958498
If we subtract 0 from 120, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 16:
506 can be fit into 1200 2 times, resulting in a remainder of 188.
The next digit of our result is 2. 
Result so far: 164817.95849802
Subtracting 1012 from 1200 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

In conclusion, the division gives 164817.95849802 with a balance of 1.88e-07.
