13599700 ÷ 676 
The aim is to understand the frequency of 676 in 13599700.

Step 1:
If we divide 1 by 676, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 676

Step 2:
13 divided by 676 is 0 with a remainder of 13.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 13 after subtracting 0 from 13.
Append the next digit (5) from the dividend to 13 and continue with: 135 / 676

Advancing to step 3:
135 divided by 676 is 0 with a remainder of 135.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 135, we end up with 135.
Include the next digit (9) from the dividend after 135, then repeat: 1359 / 676

Step 4:
The number 676 fits into 1359 2 times, leaving a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 1352 from 1359 and we're left with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 676

Step 5:
676 goes into 79 0 times with a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 20.0
Subtract 0 from 79 to get 79.
Take the next digit (7) from the dividend and append it to 79, then repeat: 797 / 676

Step 6:
676 goes into 797 1 times with a remainder of 121.
Use 1 as the next digit of our solution. 
Result so far: 201.0
The remainder is 121 after subtracting 676 from 797.
Take the next digit (0) from the dividend and append it to 121, then repeat: 1210 / 676

Step 7:
676 can be fit into 1210 1 times, resulting in a remainder of 534.
The next digit of our result is 1. 
Result so far: 2011.0
Subtracting 676 from 1210 leaves us with 534.
Include the next digit (0) from the dividend after 534, then repeat: 5340 / 676

On to step 8:
When dividing 5340 by 676, we get 7 with a remainder of 608.
Write down 7 as next digit of the result. 
Result so far: 20117.0
Subtracting 4732 from 5340 leaves us with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

Let's proceed to step 9:
The number 676 fits into 6080 8 times, leaving a remainder of 672.
The number 8 becomes the next digit in our result. 
Result so far: 20117.8
If we take 5408 away from 6080, we end up with 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Step 10:
If we divide 6720 by 676, we get 9 and a remainder of 636.
Write down 9 as next digit of the result. 
Result so far: 20117.89
If we take 6084 away from 6720, we end up with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Moving on to step 11:
If we divide 6360 by 676, we get 9 and a remainder of 276.
Put 9 as the next digit of the answer. 
Result so far: 20117.899
Subtract 6084 from 6360 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

After the division, we end up with 20117.899 and a remainder of 0.0276.
