86478417 divided by 537 
The aim is to understand the frequency of 537 in 86478417.

Moving on to step 1:
537 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 537

Let's proceed to step 2:
If we divide 86 by 537, we get 0 and a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Include the next digit (4) from the dividend after 86, then repeat: 864 / 537

Step 3:
537 goes into 864 1 times with a remainder of 327.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 537 from 864 and we're left with 327.
Append the next digit (7) from the dividend to 327 and continue with: 3277 / 537

Moving on to step 4:
When dividing 3277 by 537, we get 6 with a remainder of 55.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 55 after subtracting 3222 from 3277.
Take the next digit (8) from the dividend and append it to 55, then repeat: 558 / 537

Let's proceed to step 5:
537 can be fit into 558 1 times, resulting in a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 161.0
The remainder is 21 after subtracting 537 from 558.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 537

Let's proceed to step 6:
When dividing 214 by 537, we get 0 with a remainder of 214.
Use 0 as the next digit of our solution. 
Result so far: 1610.0
If we take 0 away from 214, we end up with 214.
Grab the next digit (1) from the dividend, add it to 214, then carry on: 2141 / 537

Moving on to step 7:
2141 divided by 537 is 3 with a remainder of 530.
Put 3 as the next digit of the answer. 
Result so far: 16103.0
Subtracting 1611 from 2141 leaves us with 530.
Fetch the next digit (7) from the dividend, attach it to 530 and continue: 5307 / 537

Step 8:
5307 divided by 537 is 9 with a remainder of 474.
Use 9 as the next digit of our solution. 
Result so far: 161039.0
If we take 4833 away from 5307, we end up with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

On to step 9:
4740 divided by 537 is 8 with a remainder of 444.
The number 8 becomes the next digit in our result. 
Result so far: 161039.8
The remainder is 444 after subtracting 4296 from 4740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Let's proceed to step 10:
4440 divided by 537 is 8 with a remainder of 144.
The next digit of our result is 8. 
Result so far: 161039.88
If we take 4296 away from 4440, we end up with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

The final outcome is 161039.88, with a leftover of 0.144.
