We divide 629800 by 13
The aim is to understand the frequency of 13 in 629800.

On to step 1:
6 divided by 13 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 13

On to step 2:
13 goes into 62 4 times with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 52 from 62 to get 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 13

On to step 3:
109 divided by 13 is 8 with a remainder of 5.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
The remainder is 5 after subtracting 104 from 109.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 13

Moving on to step 4:
13 goes into 58 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 484.0
Subtract 52 from 58 to get 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 13

Let's proceed to step 5:
13 can be fit into 60 4 times, resulting in a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4844.0
If we subtract 52 from 60, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 13

Step 6:
13 can be fit into 80 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 48446.0
The remainder is 2 after subtracting 78 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
If we divide 20 by 13, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 48446.1
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.

Let's proceed to step 8:
The number 13 fits into 70 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 48446.15
If we subtract 65 from 70, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 9:
13 goes into 50 3 times with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 48446.153
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.

Let's proceed to step 10:
The number 13 fits into 110 8 times, leaving a remainder of 6.
The next digit of our result is 8. 
Result so far: 48446.1538
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 11:
If we divide 60 by 13, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 48446.15384
If we take 52 away from 60, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
13 can be fit into 80 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 48446.153846
If we subtract 78 from 80, we get 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 13:
13 goes into 20 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 48446.1538461
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 14:
13 can be fit into 70 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 48446.15384615
Subtract 65 from 70 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 48446.15384615 with a remaining 5e-09.
