86398676 divided by 505 
The aim is to understand the frequency of 505 in 86398676.

Going ahead to step 1:
505 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 505

Moving on to step 2:
The number 505 fits into 86 0 times, leaving a remainder of 86.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Include the next digit (3) from the dividend after 86, then repeat: 863 / 505

Moving on to step 3:
When dividing 863 by 505, we get 1 with a remainder of 358.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 505 away from 863, we end up with 358.
Take the next digit (9) from the dividend and append it to 358, then repeat: 3589 / 505

Let's proceed to step 4:
When dividing 3589 by 505, we get 7 with a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we subtract 3535 from 3589, we get 54.
Include the next digit (8) from the dividend after 54, then repeat: 548 / 505

On to step 5:
505 can be fit into 548 1 times, resulting in a remainder of 43.
Write down 1 as next digit of the result. 
Result so far: 171.0
If we take 505 away from 548, we end up with 43.
Bring next digit (6) of the dividend behind the 43 and repeat the process: 436 / 505

Going ahead to step 6:
When dividing 436 by 505, we get 0 with a remainder of 436.
Write down 0 as next digit of the result. 
Result so far: 1710.0
Subtract 0 from 436 to get 436.
Take the next digit (7) from the dividend and append it to 436, then repeat: 4367 / 505

Advancing to step 7:
505 goes into 4367 8 times with a remainder of 327.
Use 8 as the next digit of our solution. 
Result so far: 17108.0
Subtracting 4040 from 4367 leaves us with 327.
Grab the next digit (6) from the dividend, add it to 327, then carry on: 3276 / 505

Step 8:
If we divide 3276 by 505, we get 6 and a remainder of 246.
Use 6 as the next digit of our solution. 
Result so far: 171086.0
Subtract 3030 from 3276 to get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

On to step 9:
The number 505 fits into 2460 4 times, leaving a remainder of 440.
Write down 4 as next digit of the result. 
Result so far: 171086.4
If we take 2020 away from 2460, we end up with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Going ahead to step 10:
When dividing 4400 by 505, we get 8 with a remainder of 360.
Write down 8 as next digit of the result. 
Result so far: 171086.48
If we subtract 4040 from 4400, we get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 11:
505 can be fit into 3600 7 times, resulting in a remainder of 65.
Record the quotient 7 as the next digit in the result. 
Result so far: 171086.487
Subtract 3535 from 3600 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 12:
When dividing 650 by 505, we get 1 with a remainder of 145.
Use 1 as the next digit of our solution. 
Result so far: 171086.4871
Subtract 505 from 650 to get 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

On to step 13:
505 goes into 1450 2 times with a remainder of 440.
The number 2 becomes the next digit in our result. 
Result so far: 171086.48712
Subtracting 1010 from 1450 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Moving on to step 14:
4400 divided by 505 is 8 with a remainder of 360.
Write down 8 as next digit of the result. 
Result so far: 171086.487128
If we take 4040 away from 4400, we end up with 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 15:
If we divide 3600 by 505, we get 7 and a remainder of 65.
Record the quotient 7 as the next digit in the result. 
Result so far: 171086.4871287
If we take 3535 away from 3600, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 16:
505 can be fit into 650 1 times, resulting in a remainder of 145.
The next digit of our result is 1. 
Result so far: 171086.48712871
If we take 505 away from 650, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Our division results in 171086.48712871 with a remaining 1.45e-07.
