We look at the division of 84284826 by 649 
The aim is to understand the frequency of 649 in 84284826.

Advancing to step 1:
If we divide 8 by 649, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 649

Step 2:
649 can be fit into 84 0 times, resulting in a remainder of 84.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Fetch the next digit (2) from the dividend, attach it to 84 and continue: 842 / 649

Moving on to step 3:
When dividing 842 by 649, we get 1 with a remainder of 193.
The next digit of our result is 1. 
Result so far: 1.0
If we take 649 away from 842, we end up with 193.
Grab the next digit (8) from the dividend, add it to 193, then carry on: 1938 / 649

Step 4:
The number 649 fits into 1938 2 times, leaving a remainder of 640.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 640 after subtracting 1298 from 1938.
Take the next digit (4) from the dividend and append it to 640, then repeat: 6404 / 649

On to step 5:
When dividing 6404 by 649, we get 9 with a remainder of 563.
Put 9 as the next digit of the answer. 
Result so far: 129.0
If we take 5841 away from 6404, we end up with 563.
Bring next digit (8) of the dividend behind the 563 and repeat the process: 5638 / 649

Step 6:
649 goes into 5638 8 times with a remainder of 446.
Record the quotient 8 as the next digit in the result. 
Result so far: 1298.0
If we take 5192 away from 5638, we end up with 446.
Take the next digit (2) from the dividend and append it to 446, then repeat: 4462 / 649

Let's proceed to step 7:
When dividing 4462 by 649, we get 6 with a remainder of 568.
Write down 6 as next digit of the result. 
Result so far: 12986.0
The remainder is 568 after subtracting 3894 from 4462.
Fetch the next digit (6) from the dividend, attach it to 568 and continue: 5686 / 649

Advancing to step 8:
649 can be fit into 5686 8 times, resulting in a remainder of 494.
The next digit of our result is 8. 
Result so far: 129868.0
Subtract 5192 from 5686 to get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Advancing to step 9:
If we divide 4940 by 649, we get 7 and a remainder of 397.
Put 7 as the next digit of the answer. 
Result so far: 129868.7
Subtracting 4543 from 4940 leaves us with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Advancing to step 10:
649 can be fit into 3970 6 times, resulting in a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 129868.76
Subtract 3894 from 3970 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 11:
If we divide 760 by 649, we get 1 and a remainder of 111.
Use 1 as the next digit of our solution. 
Result so far: 129868.761
Subtract 649 from 760 to get 111.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1110, and continue the process.

Let's proceed to step 12:
If we divide 1110 by 649, we get 1 and a remainder of 461.
The number 1 becomes the next digit in our result. 
Result so far: 129868.7611
If we subtract 649 from 1110, we get 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

After the division, we end up with 129868.7611 and a remainder of 0.00461.
