We look at the division of 28182566 by 361 
The aim is to understand the frequency of 361 in 28182566.

Advancing to step 1:
361 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 361

Going ahead to step 2:
If we divide 28 by 361, we get 0 and a remainder of 28.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Append the next digit (1) from the dividend to 28 and continue with: 281 / 361

Going ahead to step 3:
361 goes into 281 0 times with a remainder of 281.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 281, we get 281.
Append the next digit (8) from the dividend to 281 and continue with: 2818 / 361

Step 4:
When dividing 2818 by 361, we get 7 with a remainder of 291.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 2527 from 2818, we get 291.
Bring next digit (2) of the dividend behind the 291 and repeat the process: 2912 / 361

Going ahead to step 5:
361 goes into 2912 8 times with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 78.0
The remainder is 24 after subtracting 2888 from 2912.
Take the next digit (5) from the dividend and append it to 24, then repeat: 245 / 361

Step 6:
If we divide 245 by 361, we get 0 and a remainder of 245.
Put 0 as the next digit of the answer. 
Result so far: 780.0
If we take 0 away from 245, we end up with 245.
Grab the next digit (6) from the dividend, add it to 245, then carry on: 2456 / 361

Moving on to step 7:
The number 361 fits into 2456 6 times, leaving a remainder of 290.
Write down 6 as next digit of the result. 
Result so far: 7806.0
Deduct 2166 from 2456 and we're left with 290.
Fetch the next digit (6) from the dividend, attach it to 290 and continue: 2906 / 361

Going ahead to step 8:
2906 divided by 361 is 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 78068.0
The remainder is 18 after subtracting 2888 from 2906.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
When dividing 180 by 361, we get 0 with a remainder of 180.
Use 0 as the next digit of our solution. 
Result so far: 78068.0
Subtracting 0 from 180 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 10:
When dividing 1800 by 361, we get 4 with a remainder of 356.
Write down 4 as next digit of the result. 
Result so far: 78068.04
If we take 1444 away from 1800, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 11:
361 can be fit into 3560 9 times, resulting in a remainder of 311.
Record the quotient 9 as the next digit in the result. 
Result so far: 78068.049
Deduct 3249 from 3560 and we're left with 311.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3110, and continue the process.

Moving on to step 12:
3110 divided by 361 is 8 with a remainder of 222.
The next digit of our result is 8. 
Result so far: 78068.0498
Deduct 2888 from 3110 and we're left with 222.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2220, and continue the process.

On to step 13:
The number 361 fits into 2220 6 times, leaving a remainder of 54.
Use 6 as the next digit of our solution. 
Result so far: 78068.04986
Deduct 2166 from 2220 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 14:
361 can be fit into 540 1 times, resulting in a remainder of 179.
Put 1 as the next digit of the answer. 
Result so far: 78068.049861
The remainder is 179 after subtracting 361 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Step 15:
361 goes into 1790 4 times with a remainder of 346.
Record the quotient 4 as the next digit in the result. 
Result so far: 78068.0498614
Subtracting 1444 from 1790 leaves us with 346.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3460, and continue the process.

Advancing to step 16:
The number 361 fits into 3460 9 times, leaving a remainder of 211.
The next digit of our result is 9. 
Result so far: 78068.04986149
Deduct 3249 from 3460 and we're left with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

After the division, we end up with 78068.04986149 and a remainder of 2.11e-07.
