We divide 663987 by 29
The aim is to understand the frequency of 29 in 663987.

Step 1:
6 divided by 29 is 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 29

Going ahead to step 2:
The number 29 fits into 66 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 58 from 66 and we're left with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 29

Let's proceed to step 3:
29 can be fit into 83 2 times, resulting in a remainder of 25.
Record the quotient 2 as the next digit in the result. 
Result so far: 22.0
If we take 58 away from 83, we end up with 25.
Include the next digit (9) from the dividend after 25, then repeat: 259 / 29

Moving on to step 4:
If we divide 259 by 29, we get 8 and a remainder of 27.
Record the quotient 8 as the next digit in the result. 
Result so far: 228.0
Subtract 232 from 259 to get 27.
Fetch the next digit (8) from the dividend, attach it to 27 and continue: 278 / 29

Going ahead to step 5:
29 can be fit into 278 9 times, resulting in a remainder of 17.
The next digit of our result is 9. 
Result so far: 2289.0
The remainder is 17 after subtracting 261 from 278.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 29

On to step 6:
If we divide 177 by 29, we get 6 and a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 22896.0
Subtract 174 from 177 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
When dividing 30 by 29, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 22896.1
The remainder is 1 after subtracting 29 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 8:
10 divided by 29 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 22896.1
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
29 goes into 100 3 times with a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 22896.103
Subtracting 87 from 100 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 10:
130 divided by 29 is 4 with a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 22896.1034
If we subtract 116 from 130, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 11:
29 can be fit into 140 4 times, resulting in a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 22896.10344
Subtract 116 from 140 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 22896.10344 with a remaining 2.4e-05.
