616712 divided by 13 
The aim is to understand the frequency of 13 in 616712.

Let's proceed to step 1:
13 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 13

Going ahead to step 2:
13 goes into 61 4 times with a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 52 from 61 leaves us with 9.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 13

Moving on to step 3:
96 divided by 13 is 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 47.0
The remainder is 5 after subtracting 91 from 96.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 13

Let's proceed to step 4:
13 can be fit into 57 4 times, resulting in a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 474.0
If we take 52 away from 57, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 13

Let's proceed to step 5:
13 can be fit into 51 3 times, resulting in a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 4743.0
If we take 39 away from 51, we end up with 12.
Grab the next digit (2) from the dividend, add it to 12, then carry on: 122 / 13

Going ahead to step 6:
When dividing 122 by 13, we get 9 with a remainder of 5.
The next digit of our result is 9. 
Result so far: 47439.0
If we take 117 away from 122, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
The number 13 fits into 50 3 times, leaving a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 47439.3
Deduct 39 from 50 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
13 goes into 110 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 47439.38
The remainder is 6 after subtracting 104 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
60 divided by 13 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 47439.384
If we subtract 52 from 60, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
13 can be fit into 80 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 47439.3846
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 11:
13 goes into 20 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 47439.38461
Subtract 13 from 20 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 12:
When dividing 70 by 13, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 47439.384615
The remainder is 5 after subtracting 65 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 13:
If we divide 50 by 13, we get 3 and a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 47439.3846153
Subtract 39 from 50 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 14:
If we divide 110 by 13, we get 8 and a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 47439.38461538
If we subtract 104 from 110, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 47439.38461538 with a remainder of 6e-09.
