85875557 ÷ 252 
The aim is to understand the frequency of 252 in 85875557.

Advancing to step 1:
252 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 252

Let's proceed to step 2:
85 divided by 252 is 0 with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Bring next digit (8) of the dividend behind the 85 and repeat the process: 858 / 252

Step 3:
252 can be fit into 858 3 times, resulting in a remainder of 102.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 756 away from 858, we end up with 102.
Append the next digit (7) from the dividend to 102 and continue with: 1027 / 252

Step 4:
252 goes into 1027 4 times with a remainder of 19.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
Subtracting 1008 from 1027 leaves us with 19.
Bring next digit (5) of the dividend behind the 19 and repeat the process: 195 / 252

Moving on to step 5:
If we divide 195 by 252, we get 0 and a remainder of 195.
The next digit of our result is 0. 
Result so far: 340.0
If we take 0 away from 195, we end up with 195.
Fetch the next digit (5) from the dividend, attach it to 195 and continue: 1955 / 252

Moving on to step 6:
252 can be fit into 1955 7 times, resulting in a remainder of 191.
The number 7 becomes the next digit in our result. 
Result so far: 3407.0
The remainder is 191 after subtracting 1764 from 1955.
Bring next digit (5) of the dividend behind the 191 and repeat the process: 1915 / 252

Moving on to step 7:
1915 divided by 252 is 7 with a remainder of 151.
Use 7 as the next digit of our solution. 
Result so far: 34077.0
If we take 1764 away from 1915, we end up with 151.
Append the next digit (7) from the dividend to 151 and continue with: 1517 / 252

Going ahead to step 8:
If we divide 1517 by 252, we get 6 and a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 340776.0
Deduct 1512 from 1517 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
If we divide 50 by 252, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 340776.0
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 10:
500 divided by 252 is 1 with a remainder of 248.
Put 1 as the next digit of the answer. 
Result so far: 340776.01
Deduct 252 from 500 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Let's proceed to step 11:
252 can be fit into 2480 9 times, resulting in a remainder of 212.
Record the quotient 9 as the next digit in the result. 
Result so far: 340776.019
If we subtract 2268 from 2480, we get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Step 12:
If we divide 2120 by 252, we get 8 and a remainder of 104.
Use 8 as the next digit of our solution. 
Result so far: 340776.0198
If we take 2016 away from 2120, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

On to step 13:
The number 252 fits into 1040 4 times, leaving a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 340776.01984
Deduct 1008 from 1040 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 14:
The number 252 fits into 320 1 times, leaving a remainder of 68.
Record the quotient 1 as the next digit in the result. 
Result so far: 340776.019841
If we subtract 252 from 320, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 15:
When dividing 680 by 252, we get 2 with a remainder of 176.
Use 2 as the next digit of our solution. 
Result so far: 340776.0198412
If we take 504 away from 680, we end up with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Advancing to step 16:
252 goes into 1760 6 times with a remainder of 248.
Put 6 as the next digit of the answer. 
Result so far: 340776.01984126
Deduct 1512 from 1760 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Our division results in 340776.01984126 with a remaining 2.48e-07.
