We look at the division of 67643806 by 964 
The aim is to understand the frequency of 964 in 67643806.

Advancing to step 1:
If we divide 6 by 964, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 964

Step 2:
If we divide 67 by 964, we get 0 and a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 67, we get 67.
Include the next digit (6) from the dividend after 67, then repeat: 676 / 964

Moving on to step 3:
When dividing 676 by 964, we get 0 with a remainder of 676.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 676 to get 676.
Take the next digit (4) from the dividend and append it to 676, then repeat: 6764 / 964

Step 4:
The number 964 fits into 6764 7 times, leaving a remainder of 16.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 6748 from 6764, we get 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 964

Advancing to step 5:
The number 964 fits into 163 0 times, leaving a remainder of 163.
The next digit of our result is 0. 
Result so far: 70.0
If we subtract 0 from 163, we get 163.
Append the next digit (8) from the dividend to 163 and continue with: 1638 / 964

Moving on to step 6:
The number 964 fits into 1638 1 times, leaving a remainder of 674.
Use 1 as the next digit of our solution. 
Result so far: 701.0
Subtract 964 from 1638 to get 674.
Bring next digit (0) of the dividend behind the 674 and repeat the process: 6740 / 964

Advancing to step 7:
964 goes into 6740 6 times with a remainder of 956.
The number 6 becomes the next digit in our result. 
Result so far: 7016.0
Subtract 5784 from 6740 to get 956.
Fetch the next digit (6) from the dividend, attach it to 956 and continue: 9566 / 964

Going ahead to step 8:
If we divide 9566 by 964, we get 9 and a remainder of 890.
Use 9 as the next digit of our solution. 
Result so far: 70169.0
Subtract 8676 from 9566 to get 890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8900, and continue the process.

Going ahead to step 9:
964 goes into 8900 9 times with a remainder of 224.
Write down 9 as next digit of the result. 
Result so far: 70169.9
Subtract 8676 from 8900 to get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Advancing to step 10:
The number 964 fits into 2240 2 times, leaving a remainder of 312.
Put 2 as the next digit of the answer. 
Result so far: 70169.92
Deduct 1928 from 2240 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Moving on to step 11:
When dividing 3120 by 964, we get 3 with a remainder of 228.
Record the quotient 3 as the next digit in the result. 
Result so far: 70169.923
Subtracting 2892 from 3120 leaves us with 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

On to step 12:
When dividing 2280 by 964, we get 2 with a remainder of 352.
Use 2 as the next digit of our solution. 
Result so far: 70169.9232
If we take 1928 away from 2280, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 13:
If we divide 3520 by 964, we get 3 and a remainder of 628.
Record the quotient 3 as the next digit in the result. 
Result so far: 70169.92323
The remainder is 628 after subtracting 2892 from 3520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

On to step 14:
If we divide 6280 by 964, we get 6 and a remainder of 496.
Use 6 as the next digit of our solution. 
Result so far: 70169.923236
Subtract 5784 from 6280 to get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

On to step 15:
964 goes into 4960 5 times with a remainder of 140.
The next digit of our result is 5. 
Result so far: 70169.9232365
Deduct 4820 from 4960 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Let's proceed to step 16:
1400 divided by 964 is 1 with a remainder of 436.
Put 1 as the next digit of the answer. 
Result so far: 70169.92323651
If we subtract 964 from 1400, we get 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

In conclusion, the division gives 70169.92323651 with a balance of 4.36e-07.
