1578596 divided by 798 
The aim is to understand the frequency of 798 in 1578596.

Going ahead to step 1:
798 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 798

Going ahead to step 2:
The number 798 fits into 15 0 times, leaving a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 798

Let's proceed to step 3:
798 can be fit into 157 0 times, resulting in a remainder of 157.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 157 and we're left with 157.
Bring next digit (8) of the dividend behind the 157 and repeat the process: 1578 / 798

Advancing to step 4:
The number 798 fits into 1578 1 times, leaving a remainder of 780.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 798 from 1578 leaves us with 780.
Fetch the next digit (5) from the dividend, attach it to 780 and continue: 7805 / 798

Moving on to step 5:
The number 798 fits into 7805 9 times, leaving a remainder of 623.
The next digit of our result is 9. 
Result so far: 19.0
If we take 7182 away from 7805, we end up with 623.
Take the next digit (9) from the dividend and append it to 623, then repeat: 6239 / 798

Let's proceed to step 6:
798 goes into 6239 7 times with a remainder of 653.
Use 7 as the next digit of our solution. 
Result so far: 197.0
Deduct 5586 from 6239 and we're left with 653.
Include the next digit (6) from the dividend after 653, then repeat: 6536 / 798

Going ahead to step 7:
When dividing 6536 by 798, we get 8 with a remainder of 152.
The number 8 becomes the next digit in our result. 
Result so far: 1978.0
If we subtract 6384 from 6536, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Let's proceed to step 8:
If we divide 1520 by 798, we get 1 and a remainder of 722.
Record the quotient 1 as the next digit in the result. 
Result so far: 1978.1
Subtract 798 from 1520 to get 722.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

Going ahead to step 9:
798 goes into 7220 9 times with a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 1978.19
If we take 7182 away from 7220, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 10:
If we divide 380 by 798, we get 0 and a remainder of 380.
Use 0 as the next digit of our solution. 
Result so far: 1978.19
The remainder is 380 after subtracting 0 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

Let's proceed to step 11:
If we divide 3800 by 798, we get 4 and a remainder of 608.
Use 4 as the next digit of our solution. 
Result so far: 1978.1904
If we take 3192 away from 3800, we end up with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

On to step 12:
If we divide 6080 by 798, we get 7 and a remainder of 494.
Put 7 as the next digit of the answer. 
Result so far: 1978.19047
Subtract 5586 from 6080 to get 494.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4940, and continue the process.

Step 13:
The number 798 fits into 4940 6 times, leaving a remainder of 152.
Use 6 as the next digit of our solution. 
Result so far: 1978.190476
The remainder is 152 after subtracting 4788 from 4940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 14:
The number 798 fits into 1520 1 times, leaving a remainder of 722.
The next digit of our result is 1. 
Result so far: 1978.1904761
The remainder is 722 after subtracting 798 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7220, and continue the process.

Moving on to step 15:
798 can be fit into 7220 9 times, resulting in a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 1978.19047619
Subtracting 7182 from 7220 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 1978.19047619 with a remaining 3.8e-08.
