We're dividing 57707724 by 998 
The aim is to understand the frequency of 998 in 57707724.

On to step 1:
998 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 998

Moving on to step 2:
998 can be fit into 57 0 times, resulting in a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Grab the next digit (7) from the dividend, add it to 57, then carry on: 577 / 998

Moving on to step 3:
When dividing 577 by 998, we get 0 with a remainder of 577.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 577, we end up with 577.
Fetch the next digit (0) from the dividend, attach it to 577 and continue: 5770 / 998

Step 4:
When dividing 5770 by 998, we get 5 with a remainder of 780.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 4990 from 5770 leaves us with 780.
Take the next digit (7) from the dividend and append it to 780, then repeat: 7807 / 998

Let's proceed to step 5:
998 can be fit into 7807 7 times, resulting in a remainder of 821.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
Deduct 6986 from 7807 and we're left with 821.
Include the next digit (7) from the dividend after 821, then repeat: 8217 / 998

Moving on to step 6:
8217 divided by 998 is 8 with a remainder of 233.
Use 8 as the next digit of our solution. 
Result so far: 578.0
If we take 7984 away from 8217, we end up with 233.
Take the next digit (2) from the dividend and append it to 233, then repeat: 2332 / 998

Step 7:
If we divide 2332 by 998, we get 2 and a remainder of 336.
Put 2 as the next digit of the answer. 
Result so far: 5782.0
Subtract 1996 from 2332 to get 336.
Append the next digit (4) from the dividend to 336 and continue with: 3364 / 998

Moving on to step 8:
When dividing 3364 by 998, we get 3 with a remainder of 370.
Record the quotient 3 as the next digit in the result. 
Result so far: 57823.0
The remainder is 370 after subtracting 2994 from 3364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

On to step 9:
998 can be fit into 3700 3 times, resulting in a remainder of 706.
Record the quotient 3 as the next digit in the result. 
Result so far: 57823.3
The remainder is 706 after subtracting 2994 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Going ahead to step 10:
7060 divided by 998 is 7 with a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 57823.37
Subtract 6986 from 7060 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 11:
740 divided by 998 is 0 with a remainder of 740.
Write down 0 as next digit of the result. 
Result so far: 57823.37
Deduct 0 from 740 and we're left with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

Step 12:
The number 998 fits into 7400 7 times, leaving a remainder of 414.
The next digit of our result is 7. 
Result so far: 57823.3707
Subtract 6986 from 7400 to get 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 13:
4140 divided by 998 is 4 with a remainder of 148.
Put 4 as the next digit of the answer. 
Result so far: 57823.37074
Subtract 3992 from 4140 to get 148.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1480, and continue the process.

On to step 14:
1480 divided by 998 is 1 with a remainder of 482.
Use 1 as the next digit of our solution. 
Result so far: 57823.370741
Subtracting 998 from 1480 leaves us with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Let's proceed to step 15:
998 goes into 4820 4 times with a remainder of 828.
The next digit of our result is 4. 
Result so far: 57823.3707414
Subtract 3992 from 4820 to get 828.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8280, and continue the process.

Advancing to step 16:
When dividing 8280 by 998, we get 8 with a remainder of 296.
Write down 8 as next digit of the result. 
Result so far: 57823.37074148
Subtracting 7984 from 8280 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

The final outcome is 57823.37074148, with a leftover of 2.96e-07.
