We're dividing 64334760 by 961 
The aim is to understand the frequency of 961 in 64334760.

Going ahead to step 1:
961 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 961

Moving on to step 2:
The number 961 fits into 64 0 times, leaving a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Grab the next digit (3) from the dividend, add it to 64, then carry on: 643 / 961

On to step 3:
If we divide 643 by 961, we get 0 and a remainder of 643.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 643 to get 643.
Take the next digit (3) from the dividend and append it to 643, then repeat: 6433 / 961

Moving on to step 4:
When dividing 6433 by 961, we get 6 with a remainder of 667.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 5766 from 6433 to get 667.
Append the next digit (4) from the dividend to 667 and continue with: 6674 / 961

Let's proceed to step 5:
When dividing 6674 by 961, we get 6 with a remainder of 908.
Put 6 as the next digit of the answer. 
Result so far: 66.0
Subtract 5766 from 6674 to get 908.
Include the next digit (7) from the dividend after 908, then repeat: 9087 / 961

Going ahead to step 6:
When dividing 9087 by 961, we get 9 with a remainder of 438.
Write down 9 as next digit of the result. 
Result so far: 669.0
The remainder is 438 after subtracting 8649 from 9087.
Include the next digit (6) from the dividend after 438, then repeat: 4386 / 961

On to step 7:
The number 961 fits into 4386 4 times, leaving a remainder of 542.
The next digit of our result is 4. 
Result so far: 6694.0
The remainder is 542 after subtracting 3844 from 4386.
Include the next digit (0) from the dividend after 542, then repeat: 5420 / 961

Going ahead to step 8:
961 goes into 5420 5 times with a remainder of 615.
The number 5 becomes the next digit in our result. 
Result so far: 66945.0
Subtract 4805 from 5420 to get 615.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6150, and continue the process.

Step 9:
961 can be fit into 6150 6 times, resulting in a remainder of 384.
Put 6 as the next digit of the answer. 
Result so far: 66945.6
If we take 5766 away from 6150, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

On to step 10:
3840 divided by 961 is 3 with a remainder of 957.
The next digit of our result is 3. 
Result so far: 66945.63
If we subtract 2883 from 3840, we get 957.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9570, and continue the process.

On to step 11:
The number 961 fits into 9570 9 times, leaving a remainder of 921.
Write down 9 as next digit of the result. 
Result so far: 66945.639
Subtract 8649 from 9570 to get 921.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9210, and continue the process.

Going ahead to step 12:
961 goes into 9210 9 times with a remainder of 561.
Put 9 as the next digit of the answer. 
Result so far: 66945.6399
Deduct 8649 from 9210 and we're left with 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

The quotient of the division is 66945.6399, and the remainder is 0.00561.
