9626138 divided by 577 
The aim is to understand the frequency of 577 in 9626138.

Step 1:
9 divided by 577 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (6) from the dividend and append it to 9, then repeat: 96 / 577

On to step 2:
577 can be fit into 96 0 times, resulting in a remainder of 96.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 96 after subtracting 0 from 96.
Fetch the next digit (2) from the dividend, attach it to 96 and continue: 962 / 577

On to step 3:
962 divided by 577 is 1 with a remainder of 385.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 577 from 962, we get 385.
Fetch the next digit (6) from the dividend, attach it to 385 and continue: 3856 / 577

Step 4:
3856 divided by 577 is 6 with a remainder of 394.
Write down 6 as next digit of the result. 
Result so far: 16.0
If we take 3462 away from 3856, we end up with 394.
Bring next digit (1) of the dividend behind the 394 and repeat the process: 3941 / 577

Moving on to step 5:
If we divide 3941 by 577, we get 6 and a remainder of 479.
The next digit of our result is 6. 
Result so far: 166.0
If we take 3462 away from 3941, we end up with 479.
Fetch the next digit (3) from the dividend, attach it to 479 and continue: 4793 / 577

Moving on to step 6:
577 goes into 4793 8 times with a remainder of 177.
Use 8 as the next digit of our solution. 
Result so far: 1668.0
The remainder is 177 after subtracting 4616 from 4793.
Append the next digit (8) from the dividend to 177 and continue with: 1778 / 577

Going ahead to step 7:
The number 577 fits into 1778 3 times, leaving a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 16683.0
If we take 1731 away from 1778, we end up with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 8:
470 divided by 577 is 0 with a remainder of 470.
The number 0 becomes the next digit in our result. 
Result so far: 16683.0
If we subtract 0 from 470, we get 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Going ahead to step 9:
If we divide 4700 by 577, we get 8 and a remainder of 84.
Use 8 as the next digit of our solution. 
Result so far: 16683.08
If we subtract 4616 from 4700, we get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 10:
577 goes into 840 1 times with a remainder of 263.
The number 1 becomes the next digit in our result. 
Result so far: 16683.081
If we subtract 577 from 840, we get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Advancing to step 11:
The number 577 fits into 2630 4 times, leaving a remainder of 322.
The next digit of our result is 4. 
Result so far: 16683.0814
The remainder is 322 after subtracting 2308 from 2630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Going ahead to step 12:
If we divide 3220 by 577, we get 5 and a remainder of 335.
The next digit of our result is 5. 
Result so far: 16683.08145
If we subtract 2885 from 3220, we get 335.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3350, and continue the process.

Let's proceed to step 13:
If we divide 3350 by 577, we get 5 and a remainder of 465.
Put 5 as the next digit of the answer. 
Result so far: 16683.081455
Deduct 2885 from 3350 and we're left with 465.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4650, and continue the process.

In conclusion, the division gives 16683.081455 with a balance of 4.65e-05.
