We look at the division of 52121157 by 567 
The aim is to understand the frequency of 567 in 52121157.

Step 1:
5 divided by 567 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 567

Going ahead to step 2:
The number 567 fits into 52 0 times, leaving a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Append the next digit (1) from the dividend to 52 and continue with: 521 / 567

Advancing to step 3:
If we divide 521 by 567, we get 0 and a remainder of 521.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 521 and we're left with 521.
Grab the next digit (2) from the dividend, add it to 521, then carry on: 5212 / 567

Moving on to step 4:
The number 567 fits into 5212 9 times, leaving a remainder of 109.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we take 5103 away from 5212, we end up with 109.
Fetch the next digit (1) from the dividend, attach it to 109 and continue: 1091 / 567

On to step 5:
567 can be fit into 1091 1 times, resulting in a remainder of 524.
Write down 1 as next digit of the result. 
Result so far: 91.0
Subtracting 567 from 1091 leaves us with 524.
Fetch the next digit (1) from the dividend, attach it to 524 and continue: 5241 / 567

Step 6:
567 goes into 5241 9 times with a remainder of 138.
Put 9 as the next digit of the answer. 
Result so far: 919.0
If we subtract 5103 from 5241, we get 138.
Grab the next digit (5) from the dividend, add it to 138, then carry on: 1385 / 567

On to step 7:
The number 567 fits into 1385 2 times, leaving a remainder of 251.
Put 2 as the next digit of the answer. 
Result so far: 9192.0
If we take 1134 away from 1385, we end up with 251.
Take the next digit (7) from the dividend and append it to 251, then repeat: 2517 / 567

On to step 8:
2517 divided by 567 is 4 with a remainder of 249.
The next digit of our result is 4. 
Result so far: 91924.0
Subtracting 2268 from 2517 leaves us with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Going ahead to step 9:
If we divide 2490 by 567, we get 4 and a remainder of 222.
Record the quotient 4 as the next digit in the result. 
Result so far: 91924.4
Deduct 2268 from 2490 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

On to step 10:
567 can be fit into 2220 3 times, resulting in a remainder of 519.
Record the quotient 3 as the next digit in the result. 
Result so far: 91924.43
Subtract 1701 from 2220 to get 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

Moving on to step 11:
567 can be fit into 5190 9 times, resulting in a remainder of 87.
Record the quotient 9 as the next digit in the result. 
Result so far: 91924.439
Deduct 5103 from 5190 and we're left with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 12:
If we divide 870 by 567, we get 1 and a remainder of 303.
Use 1 as the next digit of our solution. 
Result so far: 91924.4391
If we subtract 567 from 870, we get 303.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3030, and continue the process.

Let's proceed to step 13:
567 goes into 3030 5 times with a remainder of 195.
The number 5 becomes the next digit in our result. 
Result so far: 91924.43915
Deduct 2835 from 3030 and we're left with 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Step 14:
567 goes into 1950 3 times with a remainder of 249.
The number 3 becomes the next digit in our result. 
Result so far: 91924.439153
Deduct 1701 from 1950 and we're left with 249.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Moving on to step 15:
2490 divided by 567 is 4 with a remainder of 222.
The next digit of our result is 4. 
Result so far: 91924.4391534
Deduct 2268 from 2490 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

Let's proceed to step 16:
If we divide 2220 by 567, we get 3 and a remainder of 519.
Write down 3 as next digit of the result. 
Result so far: 91924.43915343
Subtracting 1701 from 2220 leaves us with 519.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5190, and continue the process.

The final result is 91924.43915343 with a remainder of 5.19e-07.
