17073523 ÷ 361 
The aim is to understand the frequency of 361 in 17073523.

On to step 1:
If we divide 1 by 361, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 361

Going ahead to step 2:
361 goes into 17 0 times with a remainder of 17.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 361

Moving on to step 3:
170 divided by 361 is 0 with a remainder of 170.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 170 after subtracting 0 from 170.
Include the next digit (7) from the dividend after 170, then repeat: 1707 / 361

Let's proceed to step 4:
The number 361 fits into 1707 4 times, leaving a remainder of 263.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 263 after subtracting 1444 from 1707.
Append the next digit (3) from the dividend to 263 and continue with: 2633 / 361

Moving on to step 5:
The number 361 fits into 2633 7 times, leaving a remainder of 106.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
Subtract 2527 from 2633 to get 106.
Include the next digit (5) from the dividend after 106, then repeat: 1065 / 361

Step 6:
The number 361 fits into 1065 2 times, leaving a remainder of 343.
Write down 2 as next digit of the result. 
Result so far: 472.0
If we take 722 away from 1065, we end up with 343.
Bring next digit (2) of the dividend behind the 343 and repeat the process: 3432 / 361

Let's proceed to step 7:
If we divide 3432 by 361, we get 9 and a remainder of 183.
The number 9 becomes the next digit in our result. 
Result so far: 4729.0
The remainder is 183 after subtracting 3249 from 3432.
Include the next digit (3) from the dividend after 183, then repeat: 1833 / 361

Moving on to step 8:
When dividing 1833 by 361, we get 5 with a remainder of 28.
Write down 5 as next digit of the result. 
Result so far: 47295.0
Subtracting 1805 from 1833 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 9:
The number 361 fits into 280 0 times, leaving a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 47295.0
Deduct 0 from 280 and we're left with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

On to step 10:
If we divide 2800 by 361, we get 7 and a remainder of 273.
The number 7 becomes the next digit in our result. 
Result so far: 47295.07
If we subtract 2527 from 2800, we get 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

On to step 11:
When dividing 2730 by 361, we get 7 with a remainder of 203.
Write down 7 as next digit of the result. 
Result so far: 47295.077
If we take 2527 away from 2730, we end up with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Our division results in 47295.077 with a remaining 0.0203.
