We look at the division of 84648891 by 629 
The aim is to understand the frequency of 629 in 84648891.

Moving on to step 1:
When dividing 8 by 629, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 629

Moving on to step 2:
629 can be fit into 84 0 times, resulting in a remainder of 84.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 84, we end up with 84.
Fetch the next digit (6) from the dividend, attach it to 84 and continue: 846 / 629

Going ahead to step 3:
846 divided by 629 is 1 with a remainder of 217.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 629 from 846 to get 217.
Grab the next digit (4) from the dividend, add it to 217, then carry on: 2174 / 629

Step 4:
2174 divided by 629 is 3 with a remainder of 287.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 1887 from 2174 leaves us with 287.
Fetch the next digit (8) from the dividend, attach it to 287 and continue: 2878 / 629

Going ahead to step 5:
629 can be fit into 2878 4 times, resulting in a remainder of 362.
Write down 4 as next digit of the result. 
Result so far: 134.0
The remainder is 362 after subtracting 2516 from 2878.
Append the next digit (8) from the dividend to 362 and continue with: 3628 / 629

Let's proceed to step 6:
If we divide 3628 by 629, we get 5 and a remainder of 483.
Write down 5 as next digit of the result. 
Result so far: 1345.0
If we subtract 3145 from 3628, we get 483.
Take the next digit (9) from the dividend and append it to 483, then repeat: 4839 / 629

Going ahead to step 7:
629 goes into 4839 7 times with a remainder of 436.
The next digit of our result is 7. 
Result so far: 13457.0
The remainder is 436 after subtracting 4403 from 4839.
Fetch the next digit (1) from the dividend, attach it to 436 and continue: 4361 / 629

Going ahead to step 8:
629 can be fit into 4361 6 times, resulting in a remainder of 587.
The next digit of our result is 6. 
Result so far: 134576.0
Subtracting 3774 from 4361 leaves us with 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Going ahead to step 9:
When dividing 5870 by 629, we get 9 with a remainder of 209.
The next digit of our result is 9. 
Result so far: 134576.9
Subtract 5661 from 5870 to get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Step 10:
The number 629 fits into 2090 3 times, leaving a remainder of 203.
Record the quotient 3 as the next digit in the result. 
Result so far: 134576.93
If we subtract 1887 from 2090, we get 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Advancing to step 11:
When dividing 2030 by 629, we get 3 with a remainder of 143.
The next digit of our result is 3. 
Result so far: 134576.933
If we take 1887 away from 2030, we end up with 143.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1430, and continue the process.

The final outcome is 134576.933, with a leftover of 0.0143.
