13820996 ÷ 607 
The aim is to understand the frequency of 607 in 13820996.

Going ahead to step 1:
607 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 607

Going ahead to step 2:
13 divided by 607 is 0 with a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 607

On to step 3:
When dividing 138 by 607, we get 0 with a remainder of 138.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 138, we end up with 138.
Append the next digit (2) from the dividend to 138 and continue with: 1382 / 607

Going ahead to step 4:
When dividing 1382 by 607, we get 2 with a remainder of 168.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtracting 1214 from 1382 leaves us with 168.
Take the next digit (0) from the dividend and append it to 168, then repeat: 1680 / 607

On to step 5:
When dividing 1680 by 607, we get 2 with a remainder of 466.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we subtract 1214 from 1680, we get 466.
Append the next digit (9) from the dividend to 466 and continue with: 4669 / 607

On to step 6:
607 can be fit into 4669 7 times, resulting in a remainder of 420.
The number 7 becomes the next digit in our result. 
Result so far: 227.0
Subtract 4249 from 4669 to get 420.
Bring next digit (9) of the dividend behind the 420 and repeat the process: 4209 / 607

Advancing to step 7:
607 can be fit into 4209 6 times, resulting in a remainder of 567.
Use 6 as the next digit of our solution. 
Result so far: 2276.0
If we take 3642 away from 4209, we end up with 567.
Bring next digit (6) of the dividend behind the 567 and repeat the process: 5676 / 607

Moving on to step 8:
607 can be fit into 5676 9 times, resulting in a remainder of 213.
The number 9 becomes the next digit in our result. 
Result so far: 22769.0
If we take 5463 away from 5676, we end up with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

On to step 9:
The number 607 fits into 2130 3 times, leaving a remainder of 309.
Use 3 as the next digit of our solution. 
Result so far: 22769.3
Subtract 1821 from 2130 to get 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Going ahead to step 10:
If we divide 3090 by 607, we get 5 and a remainder of 55.
The next digit of our result is 5. 
Result so far: 22769.35
If we take 3035 away from 3090, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Going ahead to step 11:
The number 607 fits into 550 0 times, leaving a remainder of 550.
The next digit of our result is 0. 
Result so far: 22769.35
If we subtract 0 from 550, we get 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

Moving on to step 12:
5500 divided by 607 is 9 with a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 22769.3509
Subtracting 5463 from 5500 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 13:
607 goes into 370 0 times with a remainder of 370.
The next digit of our result is 0. 
Result so far: 22769.3509
Subtract 0 from 370 to get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Step 14:
607 can be fit into 3700 6 times, resulting in a remainder of 58.
Use 6 as the next digit of our solution. 
Result so far: 22769.350906
If we take 3642 away from 3700, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 15:
If we divide 580 by 607, we get 0 and a remainder of 580.
Write down 0 as next digit of the result. 
Result so far: 22769.350906
If we take 0 away from 580, we end up with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Going ahead to step 16:
607 can be fit into 5800 9 times, resulting in a remainder of 337.
Put 9 as the next digit of the answer. 
Result so far: 22769.35090609
Subtract 5463 from 5800 to get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

The final result is 22769.35090609 with a remainder of 3.37e-07.
