Let's divide 90049528 by 506
The aim is to understand the frequency of 506 in 90049528.

Going ahead to step 1:
506 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 506

Let's proceed to step 2:
506 can be fit into 90 0 times, resulting in a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Fetch the next digit (0) from the dividend, attach it to 90 and continue: 900 / 506

On to step 3:
506 can be fit into 900 1 times, resulting in a remainder of 394.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 506 from 900 leaves us with 394.
Take the next digit (4) from the dividend and append it to 394, then repeat: 3944 / 506

Moving on to step 4:
If we divide 3944 by 506, we get 7 and a remainder of 402.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 3542 from 3944 to get 402.
Include the next digit (9) from the dividend after 402, then repeat: 4029 / 506

Advancing to step 5:
506 goes into 4029 7 times with a remainder of 487.
Write down 7 as next digit of the result. 
Result so far: 177.0
Subtract 3542 from 4029 to get 487.
Include the next digit (5) from the dividend after 487, then repeat: 4875 / 506

On to step 6:
506 goes into 4875 9 times with a remainder of 321.
The number 9 becomes the next digit in our result. 
Result so far: 1779.0
Deduct 4554 from 4875 and we're left with 321.
Take the next digit (2) from the dividend and append it to 321, then repeat: 3212 / 506

Step 7:
The number 506 fits into 3212 6 times, leaving a remainder of 176.
The next digit of our result is 6. 
Result so far: 17796.0
Subtracting 3036 from 3212 leaves us with 176.
Take the next digit (8) from the dividend and append it to 176, then repeat: 1768 / 506

Step 8:
1768 divided by 506 is 3 with a remainder of 250.
The number 3 becomes the next digit in our result. 
Result so far: 177963.0
Subtracting 1518 from 1768 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 9:
The number 506 fits into 2500 4 times, leaving a remainder of 476.
Put 4 as the next digit of the answer. 
Result so far: 177963.4
Subtracting 2024 from 2500 leaves us with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Step 10:
When dividing 4760 by 506, we get 9 with a remainder of 206.
Put 9 as the next digit of the answer. 
Result so far: 177963.49
Deduct 4554 from 4760 and we're left with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Moving on to step 11:
The number 506 fits into 2060 4 times, leaving a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 177963.494
If we subtract 2024 from 2060, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 12:
360 divided by 506 is 0 with a remainder of 360.
Record the quotient 0 as the next digit in the result. 
Result so far: 177963.494
The remainder is 360 after subtracting 0 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 13:
506 goes into 3600 7 times with a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 177963.49407
Subtract 3542 from 3600 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 14:
The number 506 fits into 580 1 times, leaving a remainder of 74.
Record the quotient 1 as the next digit in the result. 
Result so far: 177963.494071
Deduct 506 from 580 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 15:
506 goes into 740 1 times with a remainder of 234.
Record the quotient 1 as the next digit in the result. 
Result so far: 177963.4940711
Subtracting 506 from 740 leaves us with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

The final outcome is 177963.4940711, with a leftover of 2.34e-06.
