858931 ÷ 52 
The aim is to understand the frequency of 52 in 858931.

Advancing to step 1:
8 divided by 52 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 52

Step 2:
If we divide 85 by 52, we get 1 and a remainder of 33.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 52 from 85 to get 33.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 52

Let's proceed to step 3:
When dividing 338 by 52, we get 6 with a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtracting 312 from 338 leaves us with 26.
Append the next digit (9) from the dividend to 26 and continue with: 269 / 52

Going ahead to step 4:
52 goes into 269 5 times with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 165.0
If we take 260 away from 269, we end up with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 52

Moving on to step 5:
52 can be fit into 93 1 times, resulting in a remainder of 41.
The number 1 becomes the next digit in our result. 
Result so far: 1651.0
The remainder is 41 after subtracting 52 from 93.
Grab the next digit (1) from the dividend, add it to 41, then carry on: 411 / 52

Let's proceed to step 6:
If we divide 411 by 52, we get 7 and a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 16517.0
If we subtract 364 from 411, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 7:
When dividing 470 by 52, we get 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 16517.9
If we take 468 away from 470, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
The number 52 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 16517.9
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
200 divided by 52 is 3 with a remainder of 44.
Use 3 as the next digit of our solution. 
Result so far: 16517.903
Subtract 156 from 200 to get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 10:
The number 52 fits into 440 8 times, leaving a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 16517.9038
If we take 416 away from 440, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 11:
52 goes into 240 4 times with a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 16517.90384
The remainder is 32 after subtracting 208 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 12:
52 goes into 320 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 16517.903846
If we subtract 312 from 320, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 13:
52 goes into 80 1 times with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 16517.9038461
Subtract 52 from 80 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 14:
280 divided by 52 is 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 16517.90384615
The remainder is 20 after subtracting 260 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 16517.90384615 and a remainder of 2e-08.
