13380053 divided by 369 
The aim is to understand the frequency of 369 in 13380053.

Advancing to step 1:
If we divide 1 by 369, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 369

Moving on to step 2:
369 can be fit into 13 0 times, resulting in a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 369

Advancing to step 3:
369 goes into 133 0 times with a remainder of 133.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 133 leaves us with 133.
Fetch the next digit (8) from the dividend, attach it to 133 and continue: 1338 / 369

Moving on to step 4:
When dividing 1338 by 369, we get 3 with a remainder of 231.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 1107 from 1338 and we're left with 231.
Bring next digit (0) of the dividend behind the 231 and repeat the process: 2310 / 369

On to step 5:
If we divide 2310 by 369, we get 6 and a remainder of 96.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
The remainder is 96 after subtracting 2214 from 2310.
Include the next digit (0) from the dividend after 96, then repeat: 960 / 369

On to step 6:
When dividing 960 by 369, we get 2 with a remainder of 222.
The number 2 becomes the next digit in our result. 
Result so far: 362.0
If we take 738 away from 960, we end up with 222.
Append the next digit (5) from the dividend to 222 and continue with: 2225 / 369

Step 7:
If we divide 2225 by 369, we get 6 and a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 3626.0
If we subtract 2214 from 2225, we get 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 369

Moving on to step 8:
369 goes into 113 0 times with a remainder of 113.
Put 0 as the next digit of the answer. 
Result so far: 36260.0
If we subtract 0 from 113, we get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Step 9:
If we divide 1130 by 369, we get 3 and a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 36260.3
Deduct 1107 from 1130 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Step 10:
369 goes into 230 0 times with a remainder of 230.
Put 0 as the next digit of the answer. 
Result so far: 36260.3
If we take 0 away from 230, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

Going ahead to step 11:
369 can be fit into 2300 6 times, resulting in a remainder of 86.
Write down 6 as next digit of the result. 
Result so far: 36260.306
If we subtract 2214 from 2300, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 12:
The number 369 fits into 860 2 times, leaving a remainder of 122.
The number 2 becomes the next digit in our result. 
Result so far: 36260.3062
Deduct 738 from 860 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Advancing to step 13:
When dividing 1220 by 369, we get 3 with a remainder of 113.
The next digit of our result is 3. 
Result so far: 36260.30623
If we subtract 1107 from 1220, we get 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

Step 14:
1130 divided by 369 is 3 with a remainder of 23.
Put 3 as the next digit of the answer. 
Result so far: 36260.306233
Subtracting 1107 from 1130 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

After the division, we end up with 36260.306233 and a remainder of 2.3e-06.
