Let's divide 90198214 by 506
The aim is to understand the frequency of 506 in 90198214.

Advancing to step 1:
506 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of 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

Going ahead to step 2:
When dividing 90 by 506, we get 0 with a remainder of 90.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Grab the next digit (1) from the dividend, add it to 90, then carry on: 901 / 506

Let's proceed to step 3:
506 goes into 901 1 times with a remainder of 395.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 506 away from 901, we end up with 395.
Bring next digit (9) of the dividend behind the 395 and repeat the process: 3959 / 506

Step 4:
If we divide 3959 by 506, we get 7 and a remainder of 417.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Deduct 3542 from 3959 and we're left with 417.
Grab the next digit (8) from the dividend, add it to 417, then carry on: 4178 / 506

Advancing to step 5:
When dividing 4178 by 506, we get 8 with a remainder of 130.
Put 8 as the next digit of the answer. 
Result so far: 178.0
Deduct 4048 from 4178 and we're left with 130.
Take the next digit (2) from the dividend and append it to 130, then repeat: 1302 / 506

Advancing to step 6:
If we divide 1302 by 506, we get 2 and a remainder of 290.
Write down 2 as next digit of the result. 
Result so far: 1782.0
Subtract 1012 from 1302 to get 290.
Fetch the next digit (1) from the dividend, attach it to 290 and continue: 2901 / 506

Going ahead to step 7:
506 goes into 2901 5 times with a remainder of 371.
The next digit of our result is 5. 
Result so far: 17825.0
The remainder is 371 after subtracting 2530 from 2901.
Fetch the next digit (4) from the dividend, attach it to 371 and continue: 3714 / 506

Advancing to step 8:
506 goes into 3714 7 times with a remainder of 172.
Record the quotient 7 as the next digit in the result. 
Result so far: 178257.0
The remainder is 172 after subtracting 3542 from 3714.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Step 9:
The number 506 fits into 1720 3 times, leaving a remainder of 202.
Put 3 as the next digit of the answer. 
Result so far: 178257.3
If we subtract 1518 from 1720, we get 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Moving on to step 10:
506 goes into 2020 3 times with a remainder of 502.
The number 3 becomes the next digit in our result. 
Result so far: 178257.33
Deduct 1518 from 2020 and we're left with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

The quotient of the division is 178257.33, and the remainder is 0.502.
