86498 divided by 52 
The aim is to understand the frequency of 52 in 86498.

Step 1:
When dividing 8 by 52, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 52

On to step 2:
86 divided by 52 is 1 with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 52 from 86 to get 34.
Grab the next digit (4) from the dividend, add it to 34, then carry on: 344 / 52

Advancing to step 3:
344 divided by 52 is 6 with a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we take 312 away from 344, we end up with 32.
Append the next digit (9) from the dividend to 32 and continue with: 329 / 52

Moving on to step 4:
If we divide 329 by 52, we get 6 and a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 166.0
The remainder is 17 after subtracting 312 from 329.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 52

Step 5:
The number 52 fits into 178 3 times, leaving a remainder of 22.
Put 3 as the next digit of the answer. 
Result so far: 1663.0
Subtract 156 from 178 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 6:
52 can be fit into 220 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 1663.4
Subtracting 208 from 220 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
If we divide 120 by 52, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 1663.42
Deduct 104 from 120 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
If we divide 160 by 52, we get 3 and a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 1663.423
Subtract 156 from 160 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
52 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 1663.423
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 10:
The number 52 fits into 400 7 times, leaving a remainder of 36.
Put 7 as the next digit of the answer. 
Result so far: 1663.42307
Subtracting 364 from 400 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
The number 52 fits into 360 6 times, leaving a remainder of 48.
Use 6 as the next digit of our solution. 
Result so far: 1663.423076
Deduct 312 from 360 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 12:
52 can be fit into 480 9 times, resulting in a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 1663.4230769
Deduct 468 from 480 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 13:
The number 52 fits into 120 2 times, leaving a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 1663.42307692
If we subtract 104 from 120, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 1663.42307692 with a remaining 1.6e-08.
