Let's divide 66659020 by 506
The aim is to understand the frequency of 506 in 66659020.

Moving on to step 1:
If we divide 6 by 506, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 506

Step 2:
When dividing 66 by 506, we get 0 with a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Include the next digit (6) from the dividend after 66, then repeat: 666 / 506

Going ahead to step 3:
The number 506 fits into 666 1 times, leaving a remainder of 160.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 506 from 666 leaves us with 160.
Bring next digit (5) of the dividend behind the 160 and repeat the process: 1605 / 506

Step 4:
506 goes into 1605 3 times with a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 1518 from 1605 to get 87.
Take the next digit (9) from the dividend and append it to 87, then repeat: 879 / 506

Let's proceed to step 5:
879 divided by 506 is 1 with a remainder of 373.
Write down 1 as next digit of the result. 
Result so far: 131.0
Subtract 506 from 879 to get 373.
Grab the next digit (0) from the dividend, add it to 373, then carry on: 3730 / 506

Advancing to step 6:
506 can be fit into 3730 7 times, resulting in a remainder of 188.
The next digit of our result is 7. 
Result so far: 1317.0
Deduct 3542 from 3730 and we're left with 188.
Grab the next digit (2) from the dividend, add it to 188, then carry on: 1882 / 506

Advancing to step 7:
506 can be fit into 1882 3 times, resulting in a remainder of 364.
Record the quotient 3 as the next digit in the result. 
Result so far: 13173.0
If we take 1518 away from 1882, we end up with 364.
Take the next digit (0) from the dividend and append it to 364, then repeat: 3640 / 506

On to step 8:
The number 506 fits into 3640 7 times, leaving a remainder of 98.
Record the quotient 7 as the next digit in the result. 
Result so far: 131737.0
If we take 3542 away from 3640, we end up with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Advancing to step 9:
The number 506 fits into 980 1 times, leaving a remainder of 474.
Use 1 as the next digit of our solution. 
Result so far: 131737.1
Deduct 506 from 980 and we're left with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Moving on to step 10:
The number 506 fits into 4740 9 times, leaving a remainder of 186.
The next digit of our result is 9. 
Result so far: 131737.19
If we subtract 4554 from 4740, we get 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 11:
The number 506 fits into 1860 3 times, leaving a remainder of 342.
Write down 3 as next digit of the result. 
Result so far: 131737.193
Subtracting 1518 from 1860 leaves us with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 12:
When dividing 3420 by 506, we get 6 with a remainder of 384.
The number 6 becomes the next digit in our result. 
Result so far: 131737.1936
If we take 3036 away from 3420, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 13:
506 goes into 3840 7 times with a remainder of 298.
Use 7 as the next digit of our solution. 
Result so far: 131737.19367
Deduct 3542 from 3840 and we're left with 298.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2980, and continue the process.

Going ahead to step 14:
2980 divided by 506 is 5 with a remainder of 450.
Use 5 as the next digit of our solution. 
Result so far: 131737.193675
Subtract 2530 from 2980 to get 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

On to step 15:
506 can be fit into 4500 8 times, resulting in a remainder of 452.
The next digit of our result is 8. 
Result so far: 131737.1936758
The remainder is 452 after subtracting 4048 from 4500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4520, and continue the process.

Let's proceed to step 16:
506 goes into 4520 8 times with a remainder of 472.
Record the quotient 8 as the next digit in the result. 
Result so far: 131737.19367588
If we take 4048 away from 4520, we end up with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

The final outcome is 131737.19367588, with a leftover of 4.72e-07.
