We're dividing 97805089 by 629 
The aim is to understand the frequency of 629 in 97805089.

Advancing to step 1:
If we divide 9 by 629, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 629

On to step 2:
629 can be fit into 97 0 times, resulting in a remainder of 97.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 97, we end up with 97.
Include the next digit (8) from the dividend after 97, then repeat: 978 / 629

Moving on to step 3:
When dividing 978 by 629, we get 1 with a remainder of 349.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 629 from 978 and we're left with 349.
Bring next digit (0) of the dividend behind the 349 and repeat the process: 3490 / 629

Moving on to step 4:
When dividing 3490 by 629, we get 5 with a remainder of 345.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtracting 3145 from 3490 leaves us with 345.
Grab the next digit (5) from the dividend, add it to 345, then carry on: 3455 / 629

Step 5:
When dividing 3455 by 629, we get 5 with a remainder of 310.
The next digit of our result is 5. 
Result so far: 155.0
The remainder is 310 after subtracting 3145 from 3455.
Include the next digit (0) from the dividend after 310, then repeat: 3100 / 629

Let's proceed to step 6:
629 goes into 3100 4 times with a remainder of 584.
The number 4 becomes the next digit in our result. 
Result so far: 1554.0
The remainder is 584 after subtracting 2516 from 3100.
Bring next digit (8) of the dividend behind the 584 and repeat the process: 5848 / 629

Let's proceed to step 7:
The number 629 fits into 5848 9 times, leaving a remainder of 187.
The number 9 becomes the next digit in our result. 
Result so far: 15549.0
If we subtract 5661 from 5848, we get 187.
Append the next digit (9) from the dividend to 187 and continue with: 1879 / 629

Let's proceed to step 8:
629 goes into 1879 2 times with a remainder of 621.
Write down 2 as next digit of the result. 
Result so far: 155492.0
If we subtract 1258 from 1879, we get 621.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6210, and continue the process.

On to step 9:
If we divide 6210 by 629, we get 9 and a remainder of 549.
Put 9 as the next digit of the answer. 
Result so far: 155492.9
The remainder is 549 after subtracting 5661 from 6210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5490, and continue the process.

Let's proceed to step 10:
If we divide 5490 by 629, we get 8 and a remainder of 458.
Use 8 as the next digit of our solution. 
Result so far: 155492.98
The remainder is 458 after subtracting 5032 from 5490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Step 11:
4580 divided by 629 is 7 with a remainder of 177.
The number 7 becomes the next digit in our result. 
Result so far: 155492.987
If we take 4403 away from 4580, we end up with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

Let's proceed to step 12:
629 goes into 1770 2 times with a remainder of 512.
Write down 2 as next digit of the result. 
Result so far: 155492.9872
The remainder is 512 after subtracting 1258 from 1770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Going ahead to step 13:
629 goes into 5120 8 times with a remainder of 88.
Record the quotient 8 as the next digit in the result. 
Result so far: 155492.98728
If we take 5032 away from 5120, we end up with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 14:
When dividing 880 by 629, we get 1 with a remainder of 251.
The number 1 becomes the next digit in our result. 
Result so far: 155492.987281
If we take 629 away from 880, we end up with 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Going ahead to step 15:
The number 629 fits into 2510 3 times, leaving a remainder of 623.
The number 3 becomes the next digit in our result. 
Result so far: 155492.9872813
If we subtract 1887 from 2510, we get 623.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6230, and continue the process.

Step 16:
629 can be fit into 6230 9 times, resulting in a remainder of 569.
Put 9 as the next digit of the answer. 
Result so far: 155492.98728139
Deduct 5661 from 6230 and we're left with 569.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5690, and continue the process.

The final result is 155492.98728139 with a remainder of 5.69e-07.
