We look at the division of 1557074 by 802 
The aim is to understand the frequency of 802 in 1557074.

Let's proceed to step 1:
The number 802 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 802

On to step 2:
The number 802 fits into 15 0 times, leaving a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 802

Going ahead to step 3:
155 divided by 802 is 0 with a remainder of 155.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 155, we get 155.
Append the next digit (7) from the dividend to 155 and continue with: 1557 / 802

Going ahead to step 4:
1557 divided by 802 is 1 with a remainder of 755.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 802 away from 1557, we end up with 755.
Fetch the next digit (0) from the dividend, attach it to 755 and continue: 7550 / 802

On to step 5:
802 goes into 7550 9 times with a remainder of 332.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we take 7218 away from 7550, we end up with 332.
Take the next digit (7) from the dividend and append it to 332, then repeat: 3327 / 802

Step 6:
802 goes into 3327 4 times with a remainder of 119.
Use 4 as the next digit of our solution. 
Result so far: 194.0
Subtracting 3208 from 3327 leaves us with 119.
Include the next digit (4) from the dividend after 119, then repeat: 1194 / 802

Moving on to step 7:
When dividing 1194 by 802, we get 1 with a remainder of 392.
Use 1 as the next digit of our solution. 
Result so far: 1941.0
Subtracting 802 from 1194 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Step 8:
When dividing 3920 by 802, we get 4 with a remainder of 712.
Use 4 as the next digit of our solution. 
Result so far: 1941.4
Subtracting 3208 from 3920 leaves us with 712.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7120, and continue the process.

Going ahead to step 9:
If we divide 7120 by 802, we get 8 and a remainder of 704.
The next digit of our result is 8. 
Result so far: 1941.48
If we take 6416 away from 7120, we end up with 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Let's proceed to step 10:
If we divide 7040 by 802, we get 8 and a remainder of 624.
Use 8 as the next digit of our solution. 
Result so far: 1941.488
If we subtract 6416 from 7040, we get 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

The final result is 1941.488 with a remainder of 0.0624.
