48351140 ÷ 686 
The aim is to understand the frequency of 686 in 48351140.

On to step 1:
686 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 686

Going ahead to step 2:
The number 686 fits into 48 0 times, leaving a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Fetch the next digit (3) from the dividend, attach it to 48 and continue: 483 / 686

Moving on to step 3:
686 goes into 483 0 times with a remainder of 483.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 483, we end up with 483.
Fetch the next digit (5) from the dividend, attach it to 483 and continue: 4835 / 686

Going ahead to step 4:
4835 divided by 686 is 7 with a remainder of 33.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 4802 from 4835 to get 33.
Include the next digit (1) from the dividend after 33, then repeat: 331 / 686

Advancing to step 5:
If we divide 331 by 686, we get 0 and a remainder of 331.
Put 0 as the next digit of the answer. 
Result so far: 70.0
The remainder is 331 after subtracting 0 from 331.
Append the next digit (1) from the dividend to 331 and continue with: 3311 / 686

Step 6:
686 goes into 3311 4 times with a remainder of 567.
The next digit of our result is 4. 
Result so far: 704.0
Deduct 2744 from 3311 and we're left with 567.
Include the next digit (4) from the dividend after 567, then repeat: 5674 / 686

Let's proceed to step 7:
686 goes into 5674 8 times with a remainder of 186.
Write down 8 as next digit of the result. 
Result so far: 7048.0
Subtract 5488 from 5674 to get 186.
Append the next digit (0) from the dividend to 186 and continue with: 1860 / 686

Going ahead to step 8:
When dividing 1860 by 686, we get 2 with a remainder of 488.
The next digit of our result is 2. 
Result so far: 70482.0
Subtracting 1372 from 1860 leaves us with 488.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4880, and continue the process.

Going ahead to step 9:
If we divide 4880 by 686, we get 7 and a remainder of 78.
Put 7 as the next digit of the answer. 
Result so far: 70482.7
The remainder is 78 after subtracting 4802 from 4880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Going ahead to step 10:
The number 686 fits into 780 1 times, leaving a remainder of 94.
The next digit of our result is 1. 
Result so far: 70482.71
The remainder is 94 after subtracting 686 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Advancing to step 11:
686 can be fit into 940 1 times, resulting in a remainder of 254.
The number 1 becomes the next digit in our result. 
Result so far: 70482.711
Subtracting 686 from 940 leaves us with 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Our division results in 70482.711 with a remaining 0.0254.
