18381784 divided by 961 
The aim is to understand the frequency of 961 in 18381784.

Step 1:
961 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 961

Moving on to step 2:
When dividing 18 by 961, we get 0 with a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Include the next digit (3) from the dividend after 18, then repeat: 183 / 961

Step 3:
The number 961 fits into 183 0 times, leaving a remainder of 183.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 183 and we're left with 183.
Include the next digit (8) from the dividend after 183, then repeat: 1838 / 961

On to step 4:
If we divide 1838 by 961, we get 1 and a remainder of 877.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 961 from 1838, we get 877.
Include the next digit (1) from the dividend after 877, then repeat: 8771 / 961

Advancing to step 5:
961 can be fit into 8771 9 times, resulting in a remainder of 122.
Write down 9 as next digit of the result. 
Result so far: 19.0
Deduct 8649 from 8771 and we're left with 122.
Grab the next digit (7) from the dividend, add it to 122, then carry on: 1227 / 961

On to step 6:
961 goes into 1227 1 times with a remainder of 266.
The next digit of our result is 1. 
Result so far: 191.0
The remainder is 266 after subtracting 961 from 1227.
Include the next digit (8) from the dividend after 266, then repeat: 2668 / 961

Going ahead to step 7:
When dividing 2668 by 961, we get 2 with a remainder of 746.
Record the quotient 2 as the next digit in the result. 
Result so far: 1912.0
The remainder is 746 after subtracting 1922 from 2668.
Take the next digit (4) from the dividend and append it to 746, then repeat: 7464 / 961

Advancing to step 8:
The number 961 fits into 7464 7 times, leaving a remainder of 737.
The number 7 becomes the next digit in our result. 
Result so far: 19127.0
Subtracting 6727 from 7464 leaves us with 737.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7370, and continue the process.

On to step 9:
961 goes into 7370 7 times with a remainder of 643.
Use 7 as the next digit of our solution. 
Result so far: 19127.7
Deduct 6727 from 7370 and we're left with 643.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6430, and continue the process.

Step 10:
When dividing 6430 by 961, we get 6 with a remainder of 664.
The number 6 becomes the next digit in our result. 
Result so far: 19127.76
The remainder is 664 after subtracting 5766 from 6430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

On to step 11:
6640 divided by 961 is 6 with a remainder of 874.
The next digit of our result is 6. 
Result so far: 19127.766
If we subtract 5766 from 6640, we get 874.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8740, and continue the process.

The final outcome is 19127.766, with a leftover of 0.0874.
