We look at the division of 361400 by 681 
The aim is to understand the frequency of 681 in 361400.

Going ahead to step 1:
681 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 681

Moving on to step 2:
The number 681 fits into 36 0 times, leaving a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 36 after subtracting 0 from 36.
Take the next digit (1) from the dividend and append it to 36, then repeat: 361 / 681

Moving on to step 3:
681 can be fit into 361 0 times, resulting in a remainder of 361.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 361 after subtracting 0 from 361.
Fetch the next digit (4) from the dividend, attach it to 361 and continue: 3614 / 681

On to step 4:
The number 681 fits into 3614 5 times, leaving a remainder of 209.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 3405 from 3614 to get 209.
Include the next digit (0) from the dividend after 209, then repeat: 2090 / 681

Going ahead to step 5:
If we divide 2090 by 681, we get 3 and a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
If we take 2043 away from 2090, we end up with 47.
Bring next digit (0) of the dividend behind the 47 and repeat the process: 470 / 681

Advancing to step 6:
681 goes into 470 0 times with a remainder of 470.
The next digit of our result is 0. 
Result so far: 530.0
If we take 0 away from 470, we end up with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Step 7:
When dividing 4700 by 681, we get 6 with a remainder of 614.
The next digit of our result is 6. 
Result so far: 530.6
Subtract 4086 from 4700 to get 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6140, and continue the process.

Step 8:
If we divide 6140 by 681, we get 9 and a remainder of 11.
The next digit of our result is 9. 
Result so far: 530.69
If we subtract 6129 from 6140, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
681 can be fit into 110 0 times, resulting in a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 530.69
Subtract 0 from 110 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Moving on to step 10:
681 can be fit into 1100 1 times, resulting in a remainder of 419.
Put 1 as the next digit of the answer. 
Result so far: 530.6901
Deduct 681 from 1100 and we're left with 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Step 11:
The number 681 fits into 4190 6 times, leaving a remainder of 104.
Use 6 as the next digit of our solution. 
Result so far: 530.69016
If we take 4086 away from 4190, we end up with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Moving on to step 12:
When dividing 1040 by 681, we get 1 with a remainder of 359.
Write down 1 as next digit of the result. 
Result so far: 530.690161
Subtracting 681 from 1040 leaves us with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Advancing to step 13:
3590 divided by 681 is 5 with a remainder of 185.
Put 5 as the next digit of the answer. 
Result so far: 530.6901615
If we subtract 3405 from 3590, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

On to step 14:
681 can be fit into 1850 2 times, resulting in a remainder of 488.
The number 2 becomes the next digit in our result. 
Result so far: 530.69016152
Subtracting 1362 from 1850 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.

The final result is 530.69016152 with a remainder of 4.88e-07.
