91608804 divided by 626 
The aim is to understand the frequency of 626 in 91608804.

Let's proceed to step 1:
9 divided by 626 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 626

Moving on to step 2:
The number 626 fits into 91 0 times, leaving a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 91 after subtracting 0 from 91.
Take the next digit (6) from the dividend and append it to 91, then repeat: 916 / 626

Advancing to step 3:
916 divided by 626 is 1 with a remainder of 290.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 626 from 916 to get 290.
Include the next digit (0) from the dividend after 290, then repeat: 2900 / 626

Moving on to step 4:
When dividing 2900 by 626, we get 4 with a remainder of 396.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
If we take 2504 away from 2900, we end up with 396.
Bring next digit (8) of the dividend behind the 396 and repeat the process: 3968 / 626

Advancing to step 5:
626 can be fit into 3968 6 times, resulting in a remainder of 212.
Use 6 as the next digit of our solution. 
Result so far: 146.0
Subtract 3756 from 3968 to get 212.
Take the next digit (8) from the dividend and append it to 212, then repeat: 2128 / 626

Let's proceed to step 6:
The number 626 fits into 2128 3 times, leaving a remainder of 250.
Put 3 as the next digit of the answer. 
Result so far: 1463.0
If we take 1878 away from 2128, we end up with 250.
Append the next digit (0) from the dividend to 250 and continue with: 2500 / 626

Let's proceed to step 7:
626 goes into 2500 3 times with a remainder of 622.
Write down 3 as next digit of the result. 
Result so far: 14633.0
Deduct 1878 from 2500 and we're left with 622.
Grab the next digit (4) from the dividend, add it to 622, then carry on: 6224 / 626

Step 8:
626 can be fit into 6224 9 times, resulting in a remainder of 590.
The number 9 becomes the next digit in our result. 
Result so far: 146339.0
If we take 5634 away from 6224, we end up with 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 9:
If we divide 5900 by 626, we get 9 and a remainder of 266.
Put 9 as the next digit of the answer. 
Result so far: 146339.9
If we take 5634 away from 5900, we end up with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Step 10:
The number 626 fits into 2660 4 times, leaving a remainder of 156.
The next digit of our result is 4. 
Result so far: 146339.94
Subtracting 2504 from 2660 leaves us with 156.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Step 11:
The number 626 fits into 1560 2 times, leaving a remainder of 308.
The number 2 becomes the next digit in our result. 
Result so far: 146339.942
If we take 1252 away from 1560, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Moving on to step 12:
The number 626 fits into 3080 4 times, leaving a remainder of 576.
Record the quotient 4 as the next digit in the result. 
Result so far: 146339.9424
Subtracting 2504 from 3080 leaves us with 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

Let's proceed to step 13:
If we divide 5760 by 626, we get 9 and a remainder of 126.
The next digit of our result is 9. 
Result so far: 146339.94249
If we take 5634 away from 5760, we end up with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

Step 14:
1260 divided by 626 is 2 with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 146339.942492
Deduct 1252 from 1260 and we're left 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.

Advancing to step 15:
80 divided by 626 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 146339.942492
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 16:
626 can be fit into 800 1 times, resulting in a remainder of 174.
Put 1 as the next digit of the answer. 
Result so far: 146339.94249201
If we subtract 626 from 800, we get 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

After the division, we end up with 146339.94249201 and a remainder of 1.74e-07.
