13578410 divided by 998 
The aim is to understand the frequency of 998 in 13578410.

Let's proceed to step 1:
When dividing 1 by 998, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 998

Step 2:
998 can be fit into 13 0 times, resulting in a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 13 to get 13.
Fetch the next digit (5) from the dividend, attach it to 13 and continue: 135 / 998

Moving on to step 3:
When dividing 135 by 998, we get 0 with a remainder of 135.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 135, we end up with 135.
Bring next digit (7) of the dividend behind the 135 and repeat the process: 1357 / 998

Advancing to step 4:
998 goes into 1357 1 times with a remainder of 359.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 998 from 1357, we get 359.
Include the next digit (8) from the dividend after 359, then repeat: 3598 / 998

On to step 5:
3598 divided by 998 is 3 with a remainder of 604.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we take 2994 away from 3598, we end up with 604.
Fetch the next digit (4) from the dividend, attach it to 604 and continue: 6044 / 998

Let's proceed to step 6:
If we divide 6044 by 998, we get 6 and a remainder of 56.
The next digit of our result is 6. 
Result so far: 136.0
The remainder is 56 after subtracting 5988 from 6044.
Include the next digit (1) from the dividend after 56, then repeat: 561 / 998

Going ahead to step 7:
998 goes into 561 0 times with a remainder of 561.
The next digit of our result is 0. 
Result so far: 1360.0
Deduct 0 from 561 and we're left with 561.
Bring next digit (0) of the dividend behind the 561 and repeat the process: 5610 / 998

Moving on to step 8:
5610 divided by 998 is 5 with a remainder of 620.
Put 5 as the next digit of the answer. 
Result so far: 13605.0
Subtract 4990 from 5610 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Advancing to step 9:
If we divide 6200 by 998, we get 6 and a remainder of 212.
The number 6 becomes the next digit in our result. 
Result so far: 13605.6
Deduct 5988 from 6200 and we're left with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Going ahead to step 10:
When dividing 2120 by 998, we get 2 with a remainder of 124.
Put 2 as the next digit of the answer. 
Result so far: 13605.62
The remainder is 124 after subtracting 1996 from 2120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 11:
1240 divided by 998 is 1 with a remainder of 242.
Use 1 as the next digit of our solution. 
Result so far: 13605.621
Subtracting 998 from 1240 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Advancing to step 12:
The number 998 fits into 2420 2 times, leaving a remainder of 424.
Write down 2 as next digit of the result. 
Result so far: 13605.6212
Deduct 1996 from 2420 and we're left with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Advancing to step 13:
998 goes into 4240 4 times with a remainder of 248.
The next digit of our result is 4. 
Result so far: 13605.62124
If we take 3992 away from 4240, we end up with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Going ahead to step 14:
The number 998 fits into 2480 2 times, leaving a remainder of 484.
Put 2 as the next digit of the answer. 
Result so far: 13605.621242
Deduct 1996 from 2480 and we're left with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Moving on to step 15:
998 can be fit into 4840 4 times, resulting in a remainder of 848.
The number 4 becomes the next digit in our result. 
Result so far: 13605.6212424
Deduct 3992 from 4840 and we're left with 848.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8480, and continue the process.

Let's proceed to step 16:
8480 divided by 998 is 8 with a remainder of 496.
Use 8 as the next digit of our solution. 
Result so far: 13605.62124248
If we subtract 7984 from 8480, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Our division results in 13605.62124248 with a remaining 4.96e-07.
