We look at the division of 49962023 by 577 
The aim is to understand the frequency of 577 in 49962023.

Going ahead to step 1:
577 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 577

Let's proceed to step 2:
The number 577 fits into 49 0 times, leaving a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Bring next digit (9) of the dividend behind the 49 and repeat the process: 499 / 577

Step 3:
577 goes into 499 0 times with a remainder of 499.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 499, we end up with 499.
Fetch the next digit (6) from the dividend, attach it to 499 and continue: 4996 / 577

Step 4:
577 goes into 4996 8 times with a remainder of 380.
The next digit of our result is 8. 
Result so far: 8.0
Subtracting 4616 from 4996 leaves us with 380.
Take the next digit (2) from the dividend and append it to 380, then repeat: 3802 / 577

Moving on to step 5:
When dividing 3802 by 577, we get 6 with a remainder of 340.
Put 6 as the next digit of the answer. 
Result so far: 86.0
The remainder is 340 after subtracting 3462 from 3802.
Append the next digit (0) from the dividend to 340 and continue with: 3400 / 577

On to step 6:
The number 577 fits into 3400 5 times, leaving a remainder of 515.
The number 5 becomes the next digit in our result. 
Result so far: 865.0
Subtracting 2885 from 3400 leaves us with 515.
Bring next digit (2) of the dividend behind the 515 and repeat the process: 5152 / 577

On to step 7:
When dividing 5152 by 577, we get 8 with a remainder of 536.
The number 8 becomes the next digit in our result. 
Result so far: 8658.0
Subtracting 4616 from 5152 leaves us with 536.
Append the next digit (3) from the dividend to 536 and continue with: 5363 / 577

Advancing to step 8:
When dividing 5363 by 577, we get 9 with a remainder of 170.
The number 9 becomes the next digit in our result. 
Result so far: 86589.0
Subtracting 5193 from 5363 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Moving on to step 9:
If we divide 1700 by 577, we get 2 and a remainder of 546.
Write down 2 as next digit of the result. 
Result so far: 86589.2
If we subtract 1154 from 1700, we get 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Step 10:
The number 577 fits into 5460 9 times, leaving a remainder of 267.
Write down 9 as next digit of the result. 
Result so far: 86589.29
If we subtract 5193 from 5460, we get 267.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2670, and continue the process.

Going ahead to step 11:
The number 577 fits into 2670 4 times, leaving a remainder of 362.
The next digit of our result is 4. 
Result so far: 86589.294
The remainder is 362 after subtracting 2308 from 2670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3620, and continue the process.

Step 12:
If we divide 3620 by 577, we get 6 and a remainder of 158.
The next digit of our result is 6. 
Result so far: 86589.2946
Deduct 3462 from 3620 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 13:
The number 577 fits into 1580 2 times, leaving a remainder of 426.
Write down 2 as next digit of the result. 
Result so far: 86589.29462
Subtracting 1154 from 1580 leaves us with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Let's proceed to step 14:
577 goes into 4260 7 times with a remainder of 221.
Put 7 as the next digit of the answer. 
Result so far: 86589.294627
The remainder is 221 after subtracting 4039 from 4260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

On to step 15:
2210 divided by 577 is 3 with a remainder of 479.
Write down 3 as next digit of the result. 
Result so far: 86589.2946273
Subtract 1731 from 2210 to get 479.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4790, and continue the process.

On to step 16:
4790 divided by 577 is 8 with a remainder of 174.
The next digit of our result is 8. 
Result so far: 86589.29462738
Subtracting 4616 from 4790 leaves us with 174.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1740, and continue the process.

The final result is 86589.29462738 with a remainder of 1.74e-07.
