We look at the division of 83074380 by 286 
The aim is to understand the frequency of 286 in 83074380.

Going ahead to step 1:
When dividing 8 by 286, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 286

Advancing to step 2:
286 can be fit into 83 0 times, resulting in a remainder of 83.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 83 and we're left with 83.
Include the next digit (0) from the dividend after 83, then repeat: 830 / 286

Let's proceed to step 3:
286 goes into 830 2 times with a remainder of 258.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 572 from 830 and we're left with 258.
Fetch the next digit (7) from the dividend, attach it to 258 and continue: 2587 / 286

Moving on to step 4:
When dividing 2587 by 286, we get 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 29.0
Deduct 2574 from 2587 and we're left with 13.
Append the next digit (4) from the dividend to 13 and continue with: 134 / 286

On to step 5:
286 goes into 134 0 times with a remainder of 134.
The number 0 becomes the next digit in our result. 
Result so far: 290.0
If we subtract 0 from 134, we get 134.
Include the next digit (3) from the dividend after 134, then repeat: 1343 / 286

Step 6:
If we divide 1343 by 286, we get 4 and a remainder of 199.
Put 4 as the next digit of the answer. 
Result so far: 2904.0
If we take 1144 away from 1343, we end up with 199.
Take the next digit (8) from the dividend and append it to 199, then repeat: 1998 / 286

Going ahead to step 7:
1998 divided by 286 is 6 with a remainder of 282.
Put 6 as the next digit of the answer. 
Result so far: 29046.0
Deduct 1716 from 1998 and we're left with 282.
Include the next digit (0) from the dividend after 282, then repeat: 2820 / 286

Advancing to step 8:
When dividing 2820 by 286, we get 9 with a remainder of 246.
The number 9 becomes the next digit in our result. 
Result so far: 290469.0
If we subtract 2574 from 2820, we get 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Let's proceed to step 9:
2460 divided by 286 is 8 with a remainder of 172.
Use 8 as the next digit of our solution. 
Result so far: 290469.8
Deduct 2288 from 2460 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Moving on to step 10:
If we divide 1720 by 286, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 290469.86
Subtract 1716 from 1720 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 11:
286 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 290469.86
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 12:
When dividing 400 by 286, we get 1 with a remainder of 114.
Put 1 as the next digit of the answer. 
Result so far: 290469.8601
The remainder is 114 after subtracting 286 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Step 13:
When dividing 1140 by 286, we get 3 with a remainder of 282.
Record the quotient 3 as the next digit in the result. 
Result so far: 290469.86013
The remainder is 282 after subtracting 858 from 1140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Advancing to step 14:
2820 divided by 286 is 9 with a remainder of 246.
Write down 9 as next digit of the result. 
Result so far: 290469.860139
Subtracting 2574 from 2820 leaves us with 246.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2460, and continue the process.

Step 15:
The number 286 fits into 2460 8 times, leaving a remainder of 172.
Use 8 as the next digit of our solution. 
Result so far: 290469.8601398
Subtracting 2288 from 2460 leaves us with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

Advancing to step 16:
1720 divided by 286 is 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 290469.86013986
If we take 1716 away from 1720, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 290469.86013986 with a remaining 4e-09.
