We look at the division of 35753730 by 557 
The aim is to understand the frequency of 557 in 35753730.

Advancing to step 1:
557 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 557

On to step 2:
The number 557 fits into 35 0 times, leaving a remainder of 35.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Include the next digit (7) from the dividend after 35, then repeat: 357 / 557

Step 3:
The number 557 fits into 357 0 times, leaving a remainder of 357.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 357 after subtracting 0 from 357.
Bring next digit (5) of the dividend behind the 357 and repeat the process: 3575 / 557

Step 4:
The number 557 fits into 3575 6 times, leaving a remainder of 233.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 3342 away from 3575, we end up with 233.
Take the next digit (3) from the dividend and append it to 233, then repeat: 2333 / 557

Let's proceed to step 5:
The number 557 fits into 2333 4 times, leaving a remainder of 105.
The next digit of our result is 4. 
Result so far: 64.0
The remainder is 105 after subtracting 2228 from 2333.
Take the next digit (7) from the dividend and append it to 105, then repeat: 1057 / 557

Moving on to step 6:
1057 divided by 557 is 1 with a remainder of 500.
Write down 1 as next digit of the result. 
Result so far: 641.0
The remainder is 500 after subtracting 557 from 1057.
Fetch the next digit (3) from the dividend, attach it to 500 and continue: 5003 / 557

Step 7:
557 can be fit into 5003 8 times, resulting in a remainder of 547.
Use 8 as the next digit of our solution. 
Result so far: 6418.0
The remainder is 547 after subtracting 4456 from 5003.
Take the next digit (0) from the dividend and append it to 547, then repeat: 5470 / 557

On to step 8:
557 can be fit into 5470 9 times, resulting in a remainder of 457.
Put 9 as the next digit of the answer. 
Result so far: 64189.0
If we subtract 5013 from 5470, we get 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Moving on to step 9:
When dividing 4570 by 557, we get 8 with a remainder of 114.
The number 8 becomes the next digit in our result. 
Result so far: 64189.8
Deduct 4456 from 4570 and we're left with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 10:
The number 557 fits into 1140 2 times, leaving a remainder of 26.
The next digit of our result is 2. 
Result so far: 64189.82
Subtract 1114 from 1140 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 11:
557 can be fit into 260 0 times, resulting in a remainder of 260.
The next digit of our result is 0. 
Result so far: 64189.82
Subtracting 0 from 260 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 12:
2600 divided by 557 is 4 with a remainder of 372.
Use 4 as the next digit of our solution. 
Result so far: 64189.8204
If we subtract 2228 from 2600, we get 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Step 13:
557 goes into 3720 6 times with a remainder of 378.
The number 6 becomes the next digit in our result. 
Result so far: 64189.82046
Subtracting 3342 from 3720 leaves us with 378.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3780, and continue the process.

Advancing to step 14:
When dividing 3780 by 557, we get 6 with a remainder of 438.
Record the quotient 6 as the next digit in the result. 
Result so far: 64189.820466
If we take 3342 away from 3780, we end up with 438.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4380, and continue the process.

After the division, we end up with 64189.820466 and a remainder of 4.38e-05.
