12398179 ÷ 522 
The aim is to understand the frequency of 522 in 12398179.

Moving on to step 1:
When dividing 1 by 522, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 522

Advancing to step 2:
522 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 522

Moving on to step 3:
522 can be fit into 123 0 times, resulting in a remainder of 123.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 123, we get 123.
Include the next digit (9) from the dividend after 123, then repeat: 1239 / 522

On to step 4:
1239 divided by 522 is 2 with a remainder of 195.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1044 from 1239 and we're left with 195.
Grab the next digit (8) from the dividend, add it to 195, then carry on: 1958 / 522

Step 5:
522 can be fit into 1958 3 times, resulting in a remainder of 392.
Use 3 as the next digit of our solution. 
Result so far: 23.0
The remainder is 392 after subtracting 1566 from 1958.
Fetch the next digit (1) from the dividend, attach it to 392 and continue: 3921 / 522

Going ahead to step 6:
When dividing 3921 by 522, we get 7 with a remainder of 267.
Put 7 as the next digit of the answer. 
Result so far: 237.0
Subtract 3654 from 3921 to get 267.
Include the next digit (7) from the dividend after 267, then repeat: 2677 / 522

Step 7:
If we divide 2677 by 522, we get 5 and a remainder of 67.
Use 5 as the next digit of our solution. 
Result so far: 2375.0
Deduct 2610 from 2677 and we're left with 67.
Fetch the next digit (9) from the dividend, attach it to 67 and continue: 679 / 522

Going ahead to step 8:
When dividing 679 by 522, we get 1 with a remainder of 157.
Put 1 as the next digit of the answer. 
Result so far: 23751.0
Subtract 522 from 679 to get 157.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1570, and continue the process.

On to step 9:
1570 divided by 522 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 23751.3
Deduct 1566 from 1570 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 10:
522 goes into 40 0 times with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 23751.3
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
400 divided by 522 is 0 with a remainder of 400.
The number 0 becomes the next digit in our result. 
Result so far: 23751.3
Subtracting 0 from 400 leaves us with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Our division results in 23751.3 with a remaining 0.04.
