83381073 ÷ 506 
The aim is to understand the frequency of 506 in 83381073.

Moving on 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
Subtracting 0 from 8 leaves us with 8.
Take the next digit (3) from the dividend and append it to 8, then repeat: 83 / 506

Moving on to step 2:
When dividing 83 by 506, we get 0 with a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 83 to get 83.
Grab the next digit (3) from the dividend, add it to 83, then carry on: 833 / 506

On to step 3:
506 can be fit into 833 1 times, resulting in a remainder of 327.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 506 from 833 leaves us with 327.
Bring next digit (8) of the dividend behind the 327 and repeat the process: 3278 / 506

Step 4:
506 goes into 3278 6 times with a remainder of 242.
The next digit of our result is 6. 
Result so far: 16.0
If we take 3036 away from 3278, we end up with 242.
Take the next digit (1) from the dividend and append it to 242, then repeat: 2421 / 506

Let's proceed to step 5:
2421 divided by 506 is 4 with a remainder of 397.
Record the quotient 4 as the next digit in the result. 
Result so far: 164.0
Deduct 2024 from 2421 and we're left with 397.
Take the next digit (0) from the dividend and append it to 397, then repeat: 3970 / 506

Advancing to step 6:
3970 divided by 506 is 7 with a remainder of 428.
Put 7 as the next digit of the answer. 
Result so far: 1647.0
If we subtract 3542 from 3970, we get 428.
Grab the next digit (7) from the dividend, add it to 428, then carry on: 4287 / 506

Let's proceed to step 7:
506 can be fit into 4287 8 times, resulting in a remainder of 239.
The next digit of our result is 8. 
Result so far: 16478.0
Subtracting 4048 from 4287 leaves us with 239.
Append the next digit (3) from the dividend to 239 and continue with: 2393 / 506

Going ahead to step 8:
506 can be fit into 2393 4 times, resulting in a remainder of 369.
The next digit of our result is 4. 
Result so far: 164784.0
Deduct 2024 from 2393 and we're left with 369.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3690, and continue the process.

On to step 9:
506 can be fit into 3690 7 times, resulting in a remainder of 148.
Record the quotient 7 as the next digit in the result. 
Result so far: 164784.7
If we take 3542 away from 3690, we end up with 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

Step 10:
1480 divided by 506 is 2 with a remainder of 468.
Record the quotient 2 as the next digit in the result. 
Result so far: 164784.72
Deduct 1012 from 1480 and we're left with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

On to step 11:
The number 506 fits into 4680 9 times, leaving a remainder of 126.
Record the quotient 9 as the next digit in the result. 
Result so far: 164784.729
Subtracting 4554 from 4680 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 12:
1260 divided by 506 is 2 with a remainder of 248.
The number 2 becomes the next digit in our result. 
Result so far: 164784.7292
If we subtract 1012 from 1260, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 13:
2480 divided by 506 is 4 with a remainder of 456.
Record the quotient 4 as the next digit in the result. 
Result so far: 164784.72924
Deduct 2024 from 2480 and we're left with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Going ahead to step 14:
506 goes into 4560 9 times with a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 164784.729249
Deduct 4554 from 4560 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 15:
The number 506 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 164784.729249
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 16:
If we divide 600 by 506, we get 1 and a remainder of 94.
The number 1 becomes the next digit in our result. 
Result so far: 164784.72924901
The remainder is 94 after subtracting 506 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

After the division, we end up with 164784.72924901 and a remainder of 9.4e-08.
