We're dividing 21584982 by 961 
The aim is to understand the frequency of 961 in 21584982.

Going ahead to step 1:
2 divided by 961 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 961

Going ahead to step 2:
When dividing 21 by 961, we get 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 961

Advancing to step 3:
961 goes into 215 0 times with a remainder of 215.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 215 to get 215.
Grab the next digit (8) from the dividend, add it to 215, then carry on: 2158 / 961

Moving on to step 4:
When dividing 2158 by 961, we get 2 with a remainder of 236.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1922 from 2158 and we're left with 236.
Grab the next digit (4) from the dividend, add it to 236, then carry on: 2364 / 961

Going ahead to step 5:
961 can be fit into 2364 2 times, resulting in a remainder of 442.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we take 1922 away from 2364, we end up with 442.
Grab the next digit (9) from the dividend, add it to 442, then carry on: 4429 / 961

Going ahead to step 6:
The number 961 fits into 4429 4 times, leaving a remainder of 585.
Use 4 as the next digit of our solution. 
Result so far: 224.0
If we take 3844 away from 4429, we end up with 585.
Take the next digit (8) from the dividend and append it to 585, then repeat: 5858 / 961

On to step 7:
5858 divided by 961 is 6 with a remainder of 92.
Use 6 as the next digit of our solution. 
Result so far: 2246.0
If we take 5766 away from 5858, we end up with 92.
Include the next digit (2) from the dividend after 92, then repeat: 922 / 961

Moving on to step 8:
961 goes into 922 0 times with a remainder of 922.
The number 0 becomes the next digit in our result. 
Result so far: 22460.0
If we take 0 away from 922, we end up with 922.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9220, and continue the process.

Moving on to step 9:
961 goes into 9220 9 times with a remainder of 571.
Record the quotient 9 as the next digit in the result. 
Result so far: 22460.9
Subtract 8649 from 9220 to get 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Advancing to step 10:
If we divide 5710 by 961, we get 5 and a remainder of 905.
Use 5 as the next digit of our solution. 
Result so far: 22460.95
Subtract 4805 from 5710 to get 905.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9050, and continue the process.

Let's proceed to step 11:
If we divide 9050 by 961, we get 9 and a remainder of 401.
The next digit of our result is 9. 
Result so far: 22460.959
Subtract 8649 from 9050 to get 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

On to step 12:
4010 divided by 961 is 4 with a remainder of 166.
The number 4 becomes the next digit in our result. 
Result so far: 22460.9594
Deduct 3844 from 4010 and we're left with 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Advancing to step 13:
961 can be fit into 1660 1 times, resulting in a remainder of 699.
Write down 1 as next digit of the result. 
Result so far: 22460.95941
Subtract 961 from 1660 to get 699.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

Moving on to step 14:
6990 divided by 961 is 7 with a remainder of 263.
Put 7 as the next digit of the answer. 
Result so far: 22460.959417
Subtract 6727 from 6990 to get 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Going ahead to step 15:
When dividing 2630 by 961, we get 2 with a remainder of 708.
Write down 2 as next digit of the result. 
Result so far: 22460.9594172
Deduct 1922 from 2630 and we're left with 708.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7080, and continue the process.

Step 16:
When dividing 7080 by 961, we get 7 with a remainder of 353.
Put 7 as the next digit of the answer. 
Result so far: 22460.95941727
Subtract 6727 from 7080 to get 353.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3530, and continue the process.

The final outcome is 22460.95941727, with a leftover of 3.53e-07.
