We're dividing 20180131 by 966 
The aim is to understand the frequency of 966 in 20180131.

Step 1:
966 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 966

Going ahead to step 2:
The number 966 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 20 to get 20.
Append the next digit (1) from the dividend to 20 and continue with: 201 / 966

Let's proceed to step 3:
The number 966 fits into 201 0 times, leaving a remainder of 201.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 201 and we're left with 201.
Bring next digit (8) of the dividend behind the 201 and repeat the process: 2018 / 966

Going ahead to step 4:
966 can be fit into 2018 2 times, resulting in a remainder of 86.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1932 from 2018 and we're left with 86.
Fetch the next digit (0) from the dividend, attach it to 86 and continue: 860 / 966

Let's proceed to step 5:
If we divide 860 by 966, we get 0 and a remainder of 860.
The next digit of our result is 0. 
Result so far: 20.0
Deduct 0 from 860 and we're left with 860.
Bring next digit (1) of the dividend behind the 860 and repeat the process: 8601 / 966

Moving on to step 6:
If we divide 8601 by 966, we get 8 and a remainder of 873.
Put 8 as the next digit of the answer. 
Result so far: 208.0
If we subtract 7728 from 8601, we get 873.
Bring next digit (3) of the dividend behind the 873 and repeat the process: 8733 / 966

Step 7:
If we divide 8733 by 966, we get 9 and a remainder of 39.
Use 9 as the next digit of our solution. 
Result so far: 2089.0
The remainder is 39 after subtracting 8694 from 8733.
Grab the next digit (1) from the dividend, add it to 39, then carry on: 391 / 966

Let's proceed to step 8:
If we divide 391 by 966, we get 0 and a remainder of 391.
The number 0 becomes the next digit in our result. 
Result so far: 20890.0
If we take 0 away from 391, we end up with 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

On to step 9:
When dividing 3910 by 966, we get 4 with a remainder of 46.
Use 4 as the next digit of our solution. 
Result so far: 20890.4
If we take 3864 away from 3910, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 10:
When dividing 460 by 966, we get 0 with a remainder of 460.
The number 0 becomes the next digit in our result. 
Result so far: 20890.4
If we take 0 away from 460, we end up with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Let's proceed to step 11:
966 can be fit into 4600 4 times, resulting in a remainder of 736.
Put 4 as the next digit of the answer. 
Result so far: 20890.404
If we subtract 3864 from 4600, we get 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Step 12:
If we divide 7360 by 966, we get 7 and a remainder of 598.
Put 7 as the next digit of the answer. 
Result so far: 20890.4047
Subtract 6762 from 7360 to get 598.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5980, and continue the process.

On to step 13:
When dividing 5980 by 966, we get 6 with a remainder of 184.
Record the quotient 6 as the next digit in the result. 
Result so far: 20890.40476
Subtracting 5796 from 5980 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 14:
966 can be fit into 1840 1 times, resulting in a remainder of 874.
Put 1 as the next digit of the answer. 
Result so far: 20890.404761
If we subtract 966 from 1840, we get 874.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8740, and continue the process.

Going ahead to step 15:
8740 divided by 966 is 9 with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 20890.4047619
Subtract 8694 from 8740 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 16:
460 divided by 966 is 0 with a remainder of 460.
Use 0 as the next digit of our solution. 
Result so far: 20890.4047619
Deduct 0 from 460 and we're left with 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4600, and continue the process.

Our division results in 20890.4047619 with a remaining 4.6e-07.
