We're dividing 64877979 by 962 
The aim is to understand the frequency of 962 in 64877979.

Let's proceed to step 1:
When dividing 6 by 962, we get 0 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.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 962

Advancing to step 2:
When dividing 64 by 962, we get 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Take the next digit (8) from the dividend and append it to 64, then repeat: 648 / 962

Advancing to step 3:
The number 962 fits into 648 0 times, leaving a remainder of 648.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 648 after subtracting 0 from 648.
Fetch the next digit (7) from the dividend, attach it to 648 and continue: 6487 / 962

Moving on to step 4:
The number 962 fits into 6487 6 times, leaving a remainder of 715.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 5772 from 6487, we get 715.
Grab the next digit (7) from the dividend, add it to 715, then carry on: 7157 / 962

Let's proceed to step 5:
The number 962 fits into 7157 7 times, leaving a remainder of 423.
The next digit of our result is 7. 
Result so far: 67.0
Deduct 6734 from 7157 and we're left with 423.
Include the next digit (9) from the dividend after 423, then repeat: 4239 / 962

On to step 6:
962 can be fit into 4239 4 times, resulting in a remainder of 391.
Use 4 as the next digit of our solution. 
Result so far: 674.0
If we take 3848 away from 4239, we end up with 391.
Take the next digit (7) from the dividend and append it to 391, then repeat: 3917 / 962

Step 7:
3917 divided by 962 is 4 with a remainder of 69.
The number 4 becomes the next digit in our result. 
Result so far: 6744.0
Subtracting 3848 from 3917 leaves us with 69.
Take the next digit (9) from the dividend and append it to 69, then repeat: 699 / 962

Going ahead to step 8:
When dividing 699 by 962, we get 0 with a remainder of 699.
Put 0 as the next digit of the answer. 
Result so far: 67440.0
Subtracting 0 from 699 leaves us with 699.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

Advancing to step 9:
962 goes into 6990 7 times with a remainder of 256.
Record the quotient 7 as the next digit in the result. 
Result so far: 67440.7
If we subtract 6734 from 6990, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 10:
If we divide 2560 by 962, we get 2 and a remainder of 636.
The number 2 becomes the next digit in our result. 
Result so far: 67440.72
If we take 1924 away from 2560, we end up with 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Moving on to step 11:
If we divide 6360 by 962, we get 6 and a remainder of 588.
Put 6 as the next digit of the answer. 
Result so far: 67440.726
If we subtract 5772 from 6360, we get 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Moving on to step 12:
The number 962 fits into 5880 6 times, leaving a remainder of 108.
The number 6 becomes the next digit in our result. 
Result so far: 67440.7266
The remainder is 108 after subtracting 5772 from 5880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

The final outcome is 67440.7266, with a leftover of 0.00108.
