12192389 ÷ 369 
The aim is to understand the frequency of 369 in 12192389.

Let's proceed to step 1:
When dividing 1 by 369, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 369

Let's proceed to step 2:
The number 369 fits into 12 0 times, leaving a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 369

Step 3:
If we divide 121 by 369, we get 0 and a remainder of 121.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 121 to get 121.
Take the next digit (9) from the dividend and append it to 121, then repeat: 1219 / 369

Step 4:
1219 divided by 369 is 3 with a remainder of 112.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 1107 from 1219 to get 112.
Take the next digit (2) from the dividend and append it to 112, then repeat: 1122 / 369

Going ahead to step 5:
If we divide 1122 by 369, we get 3 and a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 33.0
The remainder is 15 after subtracting 1107 from 1122.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 369

Going ahead to step 6:
The number 369 fits into 153 0 times, leaving a remainder of 153.
Put 0 as the next digit of the answer. 
Result so far: 330.0
Deduct 0 from 153 and we're left with 153.
Take the next digit (8) from the dividend and append it to 153, then repeat: 1538 / 369

Advancing to step 7:
369 can be fit into 1538 4 times, resulting in a remainder of 62.
The next digit of our result is 4. 
Result so far: 3304.0
Subtract 1476 from 1538 to get 62.
Include the next digit (9) from the dividend after 62, then repeat: 629 / 369

Advancing to step 8:
If we divide 629 by 369, we get 1 and a remainder of 260.
The next digit of our result is 1. 
Result so far: 33041.0
If we subtract 369 from 629, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 9:
369 goes into 2600 7 times with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 33041.7
If we subtract 2583 from 2600, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 10:
170 divided by 369 is 0 with a remainder of 170.
Write down 0 as next digit of the result. 
Result so far: 33041.7
Subtracting 0 from 170 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Advancing to step 11:
When dividing 1700 by 369, we get 4 with a remainder of 224.
Write down 4 as next digit of the result. 
Result so far: 33041.704
Deduct 1476 from 1700 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 12:
If we divide 2240 by 369, we get 6 and a remainder of 26.
The next digit of our result is 6. 
Result so far: 33041.7046
Deduct 2214 from 2240 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 13:
If we divide 260 by 369, we get 0 and a remainder of 260.
Put 0 as the next digit of the answer. 
Result so far: 33041.7046
If we take 0 away from 260, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Step 14:
When dividing 2600 by 369, we get 7 with a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 33041.704607
Deduct 2583 from 2600 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 15:
If we divide 170 by 369, we get 0 and a remainder of 170.
Put 0 as the next digit of the answer. 
Result so far: 33041.704607
The remainder is 170 after subtracting 0 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 16:
369 goes into 1700 4 times with a remainder of 224.
Record the quotient 4 as the next digit in the result. 
Result so far: 33041.70460704
Subtracting 1476 from 1700 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

The final result is 33041.70460704 with a remainder of 2.24e-07.
