12649087 ÷ 361 
The aim is to understand the frequency of 361 in 12649087.

Step 1:
361 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 361

Going ahead to step 2:
361 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Include the next digit (6) from the dividend after 12, then repeat: 126 / 361

Step 3:
The number 361 fits into 126 0 times, leaving a remainder of 126.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 126 after subtracting 0 from 126.
Append the next digit (4) from the dividend to 126 and continue with: 1264 / 361

Advancing to step 4:
The number 361 fits into 1264 3 times, leaving a remainder of 181.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 1083 from 1264, we get 181.
Bring next digit (9) of the dividend behind the 181 and repeat the process: 1819 / 361

Going ahead to step 5:
If we divide 1819 by 361, we get 5 and a remainder of 14.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
Subtract 1805 from 1819 to get 14.
Take the next digit (0) from the dividend and append it to 14, then repeat: 140 / 361

Step 6:
If we divide 140 by 361, we get 0 and a remainder of 140.
The next digit of our result is 0. 
Result so far: 350.0
The remainder is 140 after subtracting 0 from 140.
Include the next digit (8) from the dividend after 140, then repeat: 1408 / 361

On to step 7:
361 goes into 1408 3 times with a remainder of 325.
Record the quotient 3 as the next digit in the result. 
Result so far: 3503.0
Subtracting 1083 from 1408 leaves us with 325.
Grab the next digit (7) from the dividend, add it to 325, then carry on: 3257 / 361

Let's proceed to step 8:
3257 divided by 361 is 9 with a remainder of 8.
Put 9 as the next digit of the answer. 
Result so far: 35039.0
The remainder is 8 after subtracting 3249 from 3257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
The number 361 fits into 80 0 times, leaving a remainder of 80.
The next digit of our result is 0. 
Result so far: 35039.0
Subtracting 0 from 80 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 10:
The number 361 fits into 800 2 times, leaving a remainder of 78.
The number 2 becomes the next digit in our result. 
Result so far: 35039.02
If we take 722 away from 800, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 11:
If we divide 780 by 361, we get 2 and a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 35039.022
If we take 722 away from 780, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

In conclusion, the division gives 35039.022 with a balance of 0.0058.
