89582896 divided by 686 
The aim is to understand the frequency of 686 in 89582896.

On to step 1:
8 divided by 686 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 686

On to step 2:
686 goes into 89 0 times with a remainder of 89.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 89 to get 89.
Fetch the next digit (5) from the dividend, attach it to 89 and continue: 895 / 686

Let's proceed to step 3:
686 can be fit into 895 1 times, resulting in a remainder of 209.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 686 from 895 to get 209.
Append the next digit (8) from the dividend to 209 and continue with: 2098 / 686

Let's proceed to step 4:
If we divide 2098 by 686, we get 3 and a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 2058 from 2098 leaves us with 40.
Take the next digit (2) from the dividend and append it to 40, then repeat: 402 / 686

Let's proceed to step 5:
686 can be fit into 402 0 times, resulting in a remainder of 402.
The next digit of our result is 0. 
Result so far: 130.0
Subtract 0 from 402 to get 402.
Fetch the next digit (8) from the dividend, attach it to 402 and continue: 4028 / 686

Let's proceed to step 6:
When dividing 4028 by 686, we get 5 with a remainder of 598.
Record the quotient 5 as the next digit in the result. 
Result so far: 1305.0
Deduct 3430 from 4028 and we're left with 598.
Bring next digit (9) of the dividend behind the 598 and repeat the process: 5989 / 686

Going ahead to step 7:
686 goes into 5989 8 times with a remainder of 501.
Write down 8 as next digit of the result. 
Result so far: 13058.0
The remainder is 501 after subtracting 5488 from 5989.
Include the next digit (6) from the dividend after 501, then repeat: 5016 / 686

Advancing to step 8:
The number 686 fits into 5016 7 times, leaving a remainder of 214.
Write down 7 as next digit of the result. 
Result so far: 130587.0
Subtract 4802 from 5016 to get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Advancing to step 9:
2140 divided by 686 is 3 with a remainder of 82.
Put 3 as the next digit of the answer. 
Result so far: 130587.3
If we subtract 2058 from 2140, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 10:
The number 686 fits into 820 1 times, leaving a remainder of 134.
Record the quotient 1 as the next digit in the result. 
Result so far: 130587.31
Subtracting 686 from 820 leaves us with 134.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Moving on to step 11:
When dividing 1340 by 686, we get 1 with a remainder of 654.
Use 1 as the next digit of our solution. 
Result so far: 130587.311
Subtracting 686 from 1340 leaves us with 654.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6540, and continue the process.

Our division results in 130587.311 with a remaining 0.0654.
