3811444 ÷ 686 
The aim is to understand the frequency of 686 in 3811444.

Going ahead to step 1:
If we divide 3 by 686, we get 0 and a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 686

Advancing to step 2:
38 divided by 686 is 0 with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 38, we get 38.
Take the next digit (1) from the dividend and append it to 38, then repeat: 381 / 686

Let's proceed to step 3:
The number 686 fits into 381 0 times, leaving a remainder of 381.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 381 after subtracting 0 from 381.
Fetch the next digit (1) from the dividend, attach it to 381 and continue: 3811 / 686

Advancing to step 4:
3811 divided by 686 is 5 with a remainder of 381.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 3430 from 3811 and we're left with 381.
Take the next digit (4) from the dividend and append it to 381, then repeat: 3814 / 686

Advancing to step 5:
686 can be fit into 3814 5 times, resulting in a remainder of 384.
Put 5 as the next digit of the answer. 
Result so far: 55.0
Subtracting 3430 from 3814 leaves us with 384.
Include the next digit (4) from the dividend after 384, then repeat: 3844 / 686

Moving on to step 6:
3844 divided by 686 is 5 with a remainder of 414.
Record the quotient 5 as the next digit in the result. 
Result so far: 555.0
Subtract 3430 from 3844 to get 414.
Take the next digit (4) from the dividend and append it to 414, then repeat: 4144 / 686

Moving on to step 7:
The number 686 fits into 4144 6 times, leaving a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 5556.0
If we subtract 4116 from 4144, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 8:
If we divide 280 by 686, we get 0 and a remainder of 280.
Put 0 as the next digit of the answer. 
Result so far: 5556.0
If we subtract 0 from 280, we get 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 9:
The number 686 fits into 2800 4 times, leaving a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 5556.04
If we take 2744 away from 2800, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 10:
When dividing 560 by 686, we get 0 with a remainder of 560.
Write down 0 as next digit of the result. 
Result so far: 5556.04
The remainder is 560 after subtracting 0 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Step 11:
The number 686 fits into 5600 8 times, leaving a remainder of 112.
Record the quotient 8 as the next digit in the result. 
Result so far: 5556.0408
Deduct 5488 from 5600 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 12:
If we divide 1120 by 686, we get 1 and a remainder of 434.
Put 1 as the next digit of the answer. 
Result so far: 5556.04081
If we take 686 away from 1120, we end up with 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

Step 13:
The number 686 fits into 4340 6 times, leaving a remainder of 224.
The number 6 becomes the next digit in our result. 
Result so far: 5556.040816
If we take 4116 away from 4340, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 14:
686 can be fit into 2240 3 times, resulting in a remainder of 182.
The number 3 becomes the next digit in our result. 
Result so far: 5556.0408163
Subtracting 2058 from 2240 leaves us with 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

Advancing to step 15:
1820 divided by 686 is 2 with a remainder of 448.
Write down 2 as next digit of the result. 
Result so far: 5556.04081632
Subtracting 1372 from 1820 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

The quotient of the division is 5556.04081632, and the remainder is 4.48e-07.
