13749174 divided by 898 
The aim is to understand the frequency of 898 in 13749174.

Advancing to step 1:
If we divide 1 by 898, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 898

Step 2:
The number 898 fits into 13 0 times, leaving a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Fetch the next digit (7) from the dividend, attach it to 13 and continue: 137 / 898

Let's proceed to step 3:
137 divided by 898 is 0 with a remainder of 137.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 137, we get 137.
Append the next digit (4) from the dividend to 137 and continue with: 1374 / 898

On to step 4:
898 can be fit into 1374 1 times, resulting in a remainder of 476.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 898 from 1374, we get 476.
Grab the next digit (9) from the dividend, add it to 476, then carry on: 4769 / 898

Moving on to step 5:
If we divide 4769 by 898, we get 5 and a remainder of 279.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 4490 from 4769 to get 279.
Bring next digit (1) of the dividend behind the 279 and repeat the process: 2791 / 898

Advancing to step 6:
2791 divided by 898 is 3 with a remainder of 97.
The next digit of our result is 3. 
Result so far: 153.0
Deduct 2694 from 2791 and we're left with 97.
Append the next digit (7) from the dividend to 97 and continue with: 977 / 898

On to step 7:
The number 898 fits into 977 1 times, leaving a remainder of 79.
The number 1 becomes the next digit in our result. 
Result so far: 1531.0
Deduct 898 from 977 and we're left with 79.
Include the next digit (4) from the dividend after 79, then repeat: 794 / 898

Step 8:
The number 898 fits into 794 0 times, leaving a remainder of 794.
The next digit of our result is 0. 
Result so far: 15310.0
Subtracting 0 from 794 leaves us with 794.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7940, and continue the process.

Let's proceed to step 9:
If we divide 7940 by 898, we get 8 and a remainder of 756.
The number 8 becomes the next digit in our result. 
Result so far: 15310.8
If we take 7184 away from 7940, we end up with 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

Advancing to step 10:
If we divide 7560 by 898, we get 8 and a remainder of 376.
The number 8 becomes the next digit in our result. 
Result so far: 15310.88
If we subtract 7184 from 7560, we get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

The final result is 15310.88 with a remainder of 0.376.
