We look at the division of 68231775 by 961 
The aim is to understand the frequency of 961 in 68231775.

Advancing to step 1:
When dividing 6 by 961, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 961

Let's proceed to step 2:
961 can be fit into 68 0 times, resulting in a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Bring next digit (2) of the dividend behind the 68 and repeat the process: 682 / 961

On to step 3:
961 can be fit into 682 0 times, resulting in a remainder of 682.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 682, we end up with 682.
Grab the next digit (3) from the dividend, add it to 682, then carry on: 6823 / 961

On to step 4:
961 can be fit into 6823 7 times, resulting in a remainder of 96.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 6727 away from 6823, we end up with 96.
Fetch the next digit (1) from the dividend, attach it to 96 and continue: 961 / 961

Moving on to step 5:
961 goes into 961 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 71.0
Deduct 961 from 961 and we're left with 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 961

Step 6:
7 divided by 961 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 710.0
Subtract 0 from 7 to get 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 961

Moving on to step 7:
961 goes into 77 0 times with a remainder of 77.
The next digit of our result is 0. 
Result so far: 7100.0
If we subtract 0 from 77, we get 77.
Grab the next digit (5) from the dividend, add it to 77, then carry on: 775 / 961

Let's proceed to step 8:
The number 961 fits into 775 0 times, leaving a remainder of 775.
Use 0 as the next digit of our solution. 
Result so far: 71000.0
The remainder is 775 after subtracting 0 from 775.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7750, and continue the process.

Step 9:
If we divide 7750 by 961, we get 8 and a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 71000.8
If we take 7688 away from 7750, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 10:
If we divide 620 by 961, we get 0 and a remainder of 620.
The number 0 becomes the next digit in our result. 
Result so far: 71000.8
Deduct 0 from 620 and we're left with 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 11:
When dividing 6200 by 961, we get 6 with a remainder of 434.
The next digit of our result is 6. 
Result so far: 71000.806
If we subtract 5766 from 6200, we get 434.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

On to step 12:
When dividing 4340 by 961, we get 4 with a remainder of 496.
The number 4 becomes the next digit in our result. 
Result so far: 71000.8064
Deduct 3844 from 4340 and we're left with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Moving on to step 13:
961 goes into 4960 5 times with a remainder of 155.
Use 5 as the next digit of our solution. 
Result so far: 71000.80645
If we take 4805 away from 4960, we end up with 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Advancing to step 14:
The number 961 fits into 1550 1 times, leaving a remainder of 589.
The number 1 becomes the next digit in our result. 
Result so far: 71000.806451
If we take 961 away from 1550, we end up with 589.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Advancing to step 15:
5890 divided by 961 is 6 with a remainder of 124.
The number 6 becomes the next digit in our result. 
Result so far: 71000.8064516
If we subtract 5766 from 5890, we get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

On to step 16:
961 goes into 1240 1 times with a remainder of 279.
Use 1 as the next digit of our solution. 
Result so far: 71000.80645161
If we subtract 961 from 1240, we get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

After the division, we end up with 71000.80645161 and a remainder of 2.79e-07.
