We look at the division of 29815754 by 557 
The aim is to understand the frequency of 557 in 29815754.

Advancing to step 1:
If we divide 2 by 557, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 557

Let's proceed to step 2:
When dividing 29 by 557, we get 0 with a remainder of 29.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 29 and we're left with 29.
Fetch the next digit (8) from the dividend, attach it to 29 and continue: 298 / 557

Let's proceed to step 3:
If we divide 298 by 557, we get 0 and a remainder of 298.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 298, we get 298.
Grab the next digit (1) from the dividend, add it to 298, then carry on: 2981 / 557

Advancing to step 4:
557 can be fit into 2981 5 times, resulting in a remainder of 196.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Deduct 2785 from 2981 and we're left with 196.
Include the next digit (5) from the dividend after 196, then repeat: 1965 / 557

Going ahead to step 5:
If we divide 1965 by 557, we get 3 and a remainder of 294.
Write down 3 as next digit of the result. 
Result so far: 53.0
If we subtract 1671 from 1965, we get 294.
Take the next digit (7) from the dividend and append it to 294, then repeat: 2947 / 557

Moving on to step 6:
When dividing 2947 by 557, we get 5 with a remainder of 162.
The number 5 becomes the next digit in our result. 
Result so far: 535.0
Subtracting 2785 from 2947 leaves us with 162.
Take the next digit (5) from the dividend and append it to 162, then repeat: 1625 / 557

On to step 7:
When dividing 1625 by 557, we get 2 with a remainder of 511.
Record the quotient 2 as the next digit in the result. 
Result so far: 5352.0
Subtracting 1114 from 1625 leaves us with 511.
Bring next digit (4) of the dividend behind the 511 and repeat the process: 5114 / 557

Step 8:
The number 557 fits into 5114 9 times, leaving a remainder of 101.
Write down 9 as next digit of the result. 
Result so far: 53529.0
The remainder is 101 after subtracting 5013 from 5114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Advancing to step 9:
557 can be fit into 1010 1 times, resulting in a remainder of 453.
Put 1 as the next digit of the answer. 
Result so far: 53529.1
If we subtract 557 from 1010, we get 453.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4530, and continue the process.

Let's proceed to step 10:
557 can be fit into 4530 8 times, resulting in a remainder of 74.
Record the quotient 8 as the next digit in the result. 
Result so far: 53529.18
Subtract 4456 from 4530 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 11:
557 goes into 740 1 times with a remainder of 183.
The number 1 becomes the next digit in our result. 
Result so far: 53529.181
If we take 557 away from 740, we end up with 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

Let's proceed to step 12:
557 goes into 1830 3 times with a remainder of 159.
Put 3 as the next digit of the answer. 
Result so far: 53529.1813
If we subtract 1671 from 1830, we get 159.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1590, and continue the process.

Moving on to step 13:
The number 557 fits into 1590 2 times, leaving a remainder of 476.
The number 2 becomes the next digit in our result. 
Result so far: 53529.18132
The remainder is 476 after subtracting 1114 from 1590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Going ahead to step 14:
4760 divided by 557 is 8 with a remainder of 304.
Write down 8 as next digit of the result. 
Result so far: 53529.181328
Deduct 4456 from 4760 and we're left with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Step 15:
The number 557 fits into 3040 5 times, leaving a remainder of 255.
The number 5 becomes the next digit in our result. 
Result so far: 53529.1813285
Deduct 2785 from 3040 and we're left with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 16:
557 goes into 2550 4 times with a remainder of 322.
Record the quotient 4 as the next digit in the result. 
Result so far: 53529.18132854
The remainder is 322 after subtracting 2228 from 2550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

The final result is 53529.18132854 with a remainder of 3.22e-07.
