We look at the division of 16522894 by 556 
The aim is to understand the frequency of 556 in 16522894.

Moving on to step 1:
The number 556 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 556

Let's proceed to step 2:
16 divided by 556 is 0 with a remainder of 16.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 556

Step 3:
165 divided by 556 is 0 with a remainder of 165.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 165 leaves us with 165.
Bring next digit (2) of the dividend behind the 165 and repeat the process: 1652 / 556

On to step 4:
If we divide 1652 by 556, we get 2 and a remainder of 540.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 1112 away from 1652, we end up with 540.
Grab the next digit (2) from the dividend, add it to 540, then carry on: 5402 / 556

Step 5:
The number 556 fits into 5402 9 times, leaving a remainder of 398.
Use 9 as the next digit of our solution. 
Result so far: 29.0
If we subtract 5004 from 5402, we get 398.
Take the next digit (8) from the dividend and append it to 398, then repeat: 3988 / 556

Let's proceed to step 6:
The number 556 fits into 3988 7 times, leaving a remainder of 96.
The number 7 becomes the next digit in our result. 
Result so far: 297.0
Subtracting 3892 from 3988 leaves us with 96.
Grab the next digit (9) from the dividend, add it to 96, then carry on: 969 / 556

Advancing to step 7:
556 goes into 969 1 times with a remainder of 413.
The next digit of our result is 1. 
Result so far: 2971.0
Deduct 556 from 969 and we're left with 413.
Append the next digit (4) from the dividend to 413 and continue with: 4134 / 556

Step 8:
556 can be fit into 4134 7 times, resulting in a remainder of 242.
Put 7 as the next digit of the answer. 
Result so far: 29717.0
Subtract 3892 from 4134 to get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Step 9:
2420 divided by 556 is 4 with a remainder of 196.
The next digit of our result is 4. 
Result so far: 29717.4
If we take 2224 away from 2420, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 10:
556 can be fit into 1960 3 times, resulting in a remainder of 292.
Use 3 as the next digit of our solution. 
Result so far: 29717.43
Deduct 1668 from 1960 and we're left with 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

On to step 11:
The number 556 fits into 2920 5 times, leaving a remainder of 140.
Put 5 as the next digit of the answer. 
Result so far: 29717.435
Subtract 2780 from 2920 to get 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 12:
556 goes into 1400 2 times with a remainder of 288.
Write down 2 as next digit of the result. 
Result so far: 29717.4352
If we subtract 1112 from 1400, we get 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Step 13:
If we divide 2880 by 556, we get 5 and a remainder of 100.
The number 5 becomes the next digit in our result. 
Result so far: 29717.43525
Subtract 2780 from 2880 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

On to step 14:
When dividing 1000 by 556, we get 1 with a remainder of 444.
Use 1 as the next digit of our solution. 
Result so far: 29717.435251
If we take 556 away from 1000, we end up with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

On to step 15:
4440 divided by 556 is 7 with a remainder of 548.
Write down 7 as next digit of the result. 
Result so far: 29717.4352517
Deduct 3892 from 4440 and we're left with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

Moving on to step 16:
The number 556 fits into 5480 9 times, leaving a remainder of 476.
Put 9 as the next digit of the answer. 
Result so far: 29717.43525179
Subtracting 5004 from 5480 leaves us with 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

After the division, we end up with 29717.43525179 and a remainder of 4.76e-07.
