We're dividing 3756630 by 286 
The aim is to understand the frequency of 286 in 3756630.

On to step 1:
If we divide 3 by 286, 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.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 286

Let's proceed to step 2:
The number 286 fits into 37 0 times, leaving a remainder of 37.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 37, we end up with 37.
Grab the next digit (5) from the dividend, add it to 37, then carry on: 375 / 286

On to step 3:
When dividing 375 by 286, we get 1 with a remainder of 89.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 286 from 375 and we're left with 89.
Bring next digit (6) of the dividend behind the 89 and repeat the process: 896 / 286

Let's proceed to step 4:
286 can be fit into 896 3 times, resulting in a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 858 from 896 leaves us with 38.
Append the next digit (6) from the dividend to 38 and continue with: 386 / 286

On to step 5:
If we divide 386 by 286, we get 1 and a remainder of 100.
Write down 1 as next digit of the result. 
Result so far: 131.0
Deduct 286 from 386 and we're left with 100.
Grab the next digit (3) from the dividend, add it to 100, then carry on: 1003 / 286

Step 6:
If we divide 1003 by 286, we get 3 and a remainder of 145.
Write down 3 as next digit of the result. 
Result so far: 1313.0
The remainder is 145 after subtracting 858 from 1003.
Include the next digit (0) from the dividend after 145, then repeat: 1450 / 286

Advancing to step 7:
When dividing 1450 by 286, we get 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 13135.0
If we subtract 1430 from 1450, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
When dividing 200 by 286, we get 0 with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 13135.0
The remainder is 200 after subtracting 0 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 9:
If we divide 2000 by 286, we get 6 and a remainder of 284.
The next digit of our result is 6. 
Result so far: 13135.06
Subtract 1716 from 2000 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 10:
If we divide 2840 by 286, we get 9 and a remainder of 266.
Put 9 as the next digit of the answer. 
Result so far: 13135.069
If we subtract 2574 from 2840, we get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Let's proceed to step 11:
When dividing 2660 by 286, we get 9 with a remainder of 86.
Record the quotient 9 as the next digit in the result. 
Result so far: 13135.0699
Subtract 2574 from 2660 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

The final result is 13135.0699 with a remainder of 0.00086.
