We look at the division of 1846661 by 286 
The aim is to understand the frequency of 286 in 1846661.

On to step 1:
The number 286 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 286

Let's proceed to step 2:
If we divide 18 by 286, we get 0 and a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Append the next digit (4) from the dividend to 18 and continue with: 184 / 286

Step 3:
286 goes into 184 0 times with a remainder of 184.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 184 after subtracting 0 from 184.
Grab the next digit (6) from the dividend, add it to 184, then carry on: 1846 / 286

Going ahead to step 4:
When dividing 1846 by 286, we get 6 with a remainder of 130.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 130 after subtracting 1716 from 1846.
Bring next digit (6) of the dividend behind the 130 and repeat the process: 1306 / 286

Going ahead to step 5:
286 can be fit into 1306 4 times, resulting in a remainder of 162.
Write down 4 as next digit of the result. 
Result so far: 64.0
The remainder is 162 after subtracting 1144 from 1306.
Append the next digit (6) from the dividend to 162 and continue with: 1626 / 286

Let's proceed to step 6:
1626 divided by 286 is 5 with a remainder of 196.
Record the quotient 5 as the next digit in the result. 
Result so far: 645.0
Subtracting 1430 from 1626 leaves us with 196.
Take the next digit (1) from the dividend and append it to 196, then repeat: 1961 / 286

Moving on to step 7:
If we divide 1961 by 286, we get 6 and a remainder of 245.
The next digit of our result is 6. 
Result so far: 6456.0
Deduct 1716 from 1961 and we're left with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Going ahead to step 8:
286 goes into 2450 8 times with a remainder of 162.
Use 8 as the next digit of our solution. 
Result so far: 6456.8
Subtracting 2288 from 2450 leaves us with 162.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1620, and continue the process.

Step 9:
When dividing 1620 by 286, we get 5 with a remainder of 190.
Write down 5 as next digit of the result. 
Result so far: 6456.85
The remainder is 190 after subtracting 1430 from 1620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 10:
If we divide 1900 by 286, we get 6 and a remainder of 184.
Write down 6 as next digit of the result. 
Result so far: 6456.856
The remainder is 184 after subtracting 1716 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

On to step 11:
The number 286 fits into 1840 6 times, leaving a remainder of 124.
Record the quotient 6 as the next digit in the result. 
Result so far: 6456.8566
Subtract 1716 from 1840 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

After the division, we end up with 6456.8566 and a remainder of 0.00124.
