We look at the division of 35548113 by 998 
The aim is to understand the frequency of 998 in 35548113.

Going ahead to step 1:
998 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 998

Step 2:
The number 998 fits into 35 0 times, leaving a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Fetch the next digit (5) from the dividend, attach it to 35 and continue: 355 / 998

Advancing to step 3:
When dividing 355 by 998, we get 0 with a remainder of 355.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 355 after subtracting 0 from 355.
Append the next digit (4) from the dividend to 355 and continue with: 3554 / 998

Moving on to step 4:
If we divide 3554 by 998, we get 3 and a remainder of 560.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 560 after subtracting 2994 from 3554.
Grab the next digit (8) from the dividend, add it to 560, then carry on: 5608 / 998

Step 5:
998 can be fit into 5608 5 times, resulting in a remainder of 618.
Write down 5 as next digit of the result. 
Result so far: 35.0
The remainder is 618 after subtracting 4990 from 5608.
Fetch the next digit (1) from the dividend, attach it to 618 and continue: 6181 / 998

Step 6:
When dividing 6181 by 998, we get 6 with a remainder of 193.
Record the quotient 6 as the next digit in the result. 
Result so far: 356.0
Deduct 5988 from 6181 and we're left with 193.
Grab the next digit (1) from the dividend, add it to 193, then carry on: 1931 / 998

Moving on to step 7:
The number 998 fits into 1931 1 times, leaving a remainder of 933.
Use 1 as the next digit of our solution. 
Result so far: 3561.0
If we subtract 998 from 1931, we get 933.
Append the next digit (3) from the dividend to 933 and continue with: 9333 / 998

Going ahead to step 8:
The number 998 fits into 9333 9 times, leaving a remainder of 351.
Write down 9 as next digit of the result. 
Result so far: 35619.0
Subtract 8982 from 9333 to get 351.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3510, and continue the process.

Let's proceed to step 9:
998 can be fit into 3510 3 times, resulting in a remainder of 516.
Write down 3 as next digit of the result. 
Result so far: 35619.3
The remainder is 516 after subtracting 2994 from 3510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5160, and continue the process.

Let's proceed to step 10:
The number 998 fits into 5160 5 times, leaving a remainder of 170.
Use 5 as the next digit of our solution. 
Result so far: 35619.35
If we take 4990 away from 5160, we end up 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.

Let's proceed to step 11:
When dividing 1700 by 998, we get 1 with a remainder of 702.
Write down 1 as next digit of the result. 
Result so far: 35619.351
Deduct 998 from 1700 and we're left with 702.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7020, and continue the process.

On to step 12:
998 goes into 7020 7 times with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 35619.3517
Deduct 6986 from 7020 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 13:
340 divided by 998 is 0 with a remainder of 340.
The next digit of our result is 0. 
Result so far: 35619.3517
Deduct 0 from 340 and we're left with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Going ahead to step 14:
998 goes into 3400 3 times with a remainder of 406.
The number 3 becomes the next digit in our result. 
Result so far: 35619.351703
The remainder is 406 after subtracting 2994 from 3400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4060, and continue the process.

Moving on to step 15:
998 goes into 4060 4 times with a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 35619.3517034
The remainder is 68 after subtracting 3992 from 4060.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 16:
The number 998 fits into 680 0 times, leaving a remainder of 680.
Put 0 as the next digit of the answer. 
Result so far: 35619.3517034
If we take 0 away from 680, we end up with 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

The final outcome is 35619.3517034, with a leftover of 6.8e-07.
