We divide 81491534 by 506
The aim is to understand the frequency of 506 in 81491534.

Let's proceed to step 1:
If we divide 8 by 506, we get 0 and 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.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 506

Advancing to step 2:
The number 506 fits into 81 0 times, leaving a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Append the next digit (4) from the dividend to 81 and continue with: 814 / 506

Let's proceed to step 3:
If we divide 814 by 506, we get 1 and a remainder of 308.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 308 after subtracting 506 from 814.
Take the next digit (9) from the dividend and append it to 308, then repeat: 3089 / 506

Going ahead to step 4:
When dividing 3089 by 506, we get 6 with a remainder of 53.
The next digit of our result is 6. 
Result so far: 16.0
If we subtract 3036 from 3089, we get 53.
Bring next digit (1) of the dividend behind the 53 and repeat the process: 531 / 506

Going ahead to step 5:
506 goes into 531 1 times with a remainder of 25.
Record the quotient 1 as the next digit in the result. 
Result so far: 161.0
The remainder is 25 after subtracting 506 from 531.
Take the next digit (5) from the dividend and append it to 25, then repeat: 255 / 506

Moving on to step 6:
506 goes into 255 0 times with a remainder of 255.
Use 0 as the next digit of our solution. 
Result so far: 1610.0
If we subtract 0 from 255, we get 255.
Take the next digit (3) from the dividend and append it to 255, then repeat: 2553 / 506

Advancing to step 7:
2553 divided by 506 is 5 with a remainder of 23.
The next digit of our result is 5. 
Result so far: 16105.0
Subtract 2530 from 2553 to get 23.
Bring next digit (4) of the dividend behind the 23 and repeat the process: 234 / 506

Moving on to step 8:
When dividing 234 by 506, we get 0 with a remainder of 234.
Put 0 as the next digit of the answer. 
Result so far: 161050.0
If we subtract 0 from 234, we get 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

Going ahead to step 9:
When dividing 2340 by 506, we get 4 with a remainder of 316.
The next digit of our result is 4. 
Result so far: 161050.4
Subtracting 2024 from 2340 leaves us with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Going ahead to step 10:
3160 divided by 506 is 6 with a remainder of 124.
Write down 6 as next digit of the result. 
Result so far: 161050.46
Deduct 3036 from 3160 and we're left with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Advancing to step 11:
When dividing 1240 by 506, we get 2 with a remainder of 228.
Record the quotient 2 as the next digit in the result. 
Result so far: 161050.462
If we take 1012 away from 1240, we end up with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Moving on to step 12:
506 goes into 2280 4 times with a remainder of 256.
The next digit of our result is 4. 
Result so far: 161050.4624
The remainder is 256 after subtracting 2024 from 2280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 13:
506 can be fit into 2560 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 161050.46245
Subtract 2530 from 2560 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
If we divide 300 by 506, we get 0 and a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 161050.46245
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Moving on to step 15:
The number 506 fits into 3000 5 times, leaving a remainder of 470.
The number 5 becomes the next digit in our result. 
Result so far: 161050.4624505
If we take 2530 away from 3000, we end up with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Step 16:
4700 divided by 506 is 9 with a remainder of 146.
Put 9 as the next digit of the answer. 
Result so far: 161050.46245059
If we subtract 4554 from 4700, we get 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

The quotient of the division is 161050.46245059, and the remainder is 1.46e-07.
