We look at the division of 9833789 by 577 
The aim is to understand the frequency of 577 in 9833789.

Let's proceed to step 1:
577 can be fit into 9 0 times, resulting in a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 577

Moving on to step 2:
577 goes into 98 0 times with a remainder of 98.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 98, we end up with 98.
Grab the next digit (3) from the dividend, add it to 98, then carry on: 983 / 577

Going ahead to step 3:
If we divide 983 by 577, we get 1 and a remainder of 406.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 577 from 983 and we're left with 406.
Grab the next digit (3) from the dividend, add it to 406, then carry on: 4063 / 577

Step 4:
4063 divided by 577 is 7 with a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we take 4039 away from 4063, we end up with 24.
Grab the next digit (7) from the dividend, add it to 24, then carry on: 247 / 577

Step 5:
577 goes into 247 0 times with a remainder of 247.
The next digit of our result is 0. 
Result so far: 170.0
If we take 0 away from 247, we end up with 247.
Append the next digit (8) from the dividend to 247 and continue with: 2478 / 577

Going ahead to step 6:
577 goes into 2478 4 times with a remainder of 170.
Use 4 as the next digit of our solution. 
Result so far: 1704.0
The remainder is 170 after subtracting 2308 from 2478.
Grab the next digit (9) from the dividend, add it to 170, then carry on: 1709 / 577

Moving on to step 7:
The number 577 fits into 1709 2 times, leaving a remainder of 555.
Use 2 as the next digit of our solution. 
Result so far: 17042.0
If we subtract 1154 from 1709, we get 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

Moving on to step 8:
If we divide 5550 by 577, we get 9 and a remainder of 357.
The next digit of our result is 9. 
Result so far: 17042.9
Subtracting 5193 from 5550 leaves us with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

On to step 9:
577 goes into 3570 6 times with a remainder of 108.
Use 6 as the next digit of our solution. 
Result so far: 17042.96
Deduct 3462 from 3570 and we're left with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 10:
577 can be fit into 1080 1 times, resulting in a remainder of 503.
The next digit of our result is 1. 
Result so far: 17042.961
Subtracting 577 from 1080 leaves us with 503.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5030, and continue the process.

On to step 11:
577 goes into 5030 8 times with a remainder of 414.
Use 8 as the next digit of our solution. 
Result so far: 17042.9618
If we take 4616 away from 5030, we end up with 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Advancing to step 12:
If we divide 4140 by 577, we get 7 and a remainder of 101.
The next digit of our result is 7. 
Result so far: 17042.96187
Subtract 4039 from 4140 to get 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Let's proceed to step 13:
The number 577 fits into 1010 1 times, leaving a remainder of 433.
The number 1 becomes the next digit in our result. 
Result so far: 17042.961871
If we subtract 577 from 1010, we get 433.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4330, and continue the process.

Let's proceed to step 14:
577 can be fit into 4330 7 times, resulting in a remainder of 291.
The number 7 becomes the next digit in our result. 
Result so far: 17042.9618717
The remainder is 291 after subtracting 4039 from 4330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Moving on to step 15:
577 goes into 2910 5 times with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 17042.96187175
Deduct 2885 from 2910 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

The quotient of the division is 17042.96187175, and the remainder is 2.5e-08.
