99721082 divided by 961 
The aim is to understand the frequency of 961 in 99721082.

Step 1:
When dividing 9 by 961, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 961

Let's proceed to step 2:
99 divided by 961 is 0 with a remainder of 99.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 99 to get 99.
Take the next digit (7) from the dividend and append it to 99, then repeat: 997 / 961

Advancing to step 3:
If we divide 997 by 961, we get 1 and a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 961 from 997 leaves us with 36.
Bring next digit (2) of the dividend behind the 36 and repeat the process: 362 / 961

Moving on to step 4:
961 goes into 362 0 times with a remainder of 362.
Use 0 as the next digit of our solution. 
Result so far: 10.0
The remainder is 362 after subtracting 0 from 362.
Include the next digit (1) from the dividend after 362, then repeat: 3621 / 961

Going ahead to step 5:
If we divide 3621 by 961, we get 3 and a remainder of 738.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
The remainder is 738 after subtracting 2883 from 3621.
Append the next digit (0) from the dividend to 738 and continue with: 7380 / 961

Let's proceed to step 6:
7380 divided by 961 is 7 with a remainder of 653.
Record the quotient 7 as the next digit in the result. 
Result so far: 1037.0
The remainder is 653 after subtracting 6727 from 7380.
Take the next digit (8) from the dividend and append it to 653, then repeat: 6538 / 961

Advancing to step 7:
961 can be fit into 6538 6 times, resulting in a remainder of 772.
The next digit of our result is 6. 
Result so far: 10376.0
Deduct 5766 from 6538 and we're left with 772.
Append the next digit (2) from the dividend to 772 and continue with: 7722 / 961

Step 8:
If we divide 7722 by 961, we get 8 and a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 103768.0
The remainder is 34 after subtracting 7688 from 7722.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 9:
When dividing 340 by 961, we get 0 with a remainder of 340.
Put 0 as the next digit of the answer. 
Result so far: 103768.0
Subtract 0 from 340 to get 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 10:
When dividing 3400 by 961, we get 3 with a remainder of 517.
Use 3 as the next digit of our solution. 
Result so far: 103768.03
If we take 2883 away from 3400, we end up with 517.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5170, and continue the process.

Going ahead to step 11:
The number 961 fits into 5170 5 times, leaving a remainder of 365.
Put 5 as the next digit of the answer. 
Result so far: 103768.035
Subtract 4805 from 5170 to get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Moving on to step 12:
If we divide 3650 by 961, we get 3 and a remainder of 767.
The next digit of our result is 3. 
Result so far: 103768.0353
Deduct 2883 from 3650 and we're left with 767.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7670, and continue the process.

Moving on to step 13:
961 goes into 7670 7 times with a remainder of 943.
Put 7 as the next digit of the answer. 
Result so far: 103768.03537
If we subtract 6727 from 7670, we get 943.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9430, and continue the process.

Let's proceed to step 14:
961 can be fit into 9430 9 times, resulting in a remainder of 781.
Put 9 as the next digit of the answer. 
Result so far: 103768.035379
If we subtract 8649 from 9430, we get 781.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7810, and continue the process.

Step 15:
If we divide 7810 by 961, we get 8 and a remainder of 122.
Record the quotient 8 as the next digit in the result. 
Result so far: 103768.0353798
Subtract 7688 from 7810 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 16:
The number 961 fits into 1220 1 times, leaving a remainder of 259.
The next digit of our result is 1. 
Result so far: 103768.03537981
The remainder is 259 after subtracting 961 from 1220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2590, and continue the process.

The final outcome is 103768.03537981, with a leftover of 2.59e-07.
