Let's divide 664729 by 91
The aim is to understand the frequency of 91 in 664729.

Let's proceed to step 1:
91 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 91

Let's proceed to step 2:
66 divided by 91 is 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Include the next digit (4) from the dividend after 66, then repeat: 664 / 91

Let's proceed to step 3:
The number 91 fits into 664 7 times, leaving a remainder of 27.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we subtract 637 from 664, we get 27.
Append the next digit (7) from the dividend to 27 and continue with: 277 / 91

Let's proceed to step 4:
When dividing 277 by 91, we get 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 73.0
Subtracting 273 from 277 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 91

On to step 5:
When dividing 42 by 91, we get 0 with a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 730.0
The remainder is 42 after subtracting 0 from 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 91

Moving on to step 6:
91 goes into 429 4 times with a remainder of 65.
Write down 4 as next digit of the result. 
Result so far: 7304.0
Subtract 364 from 429 to get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 7:
91 can be fit into 650 7 times, resulting in a remainder of 13.
The next digit of our result is 7. 
Result so far: 7304.7
If we subtract 637 from 650, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 8:
If we divide 130 by 91, we get 1 and a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 7304.71
The remainder is 39 after subtracting 91 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 9:
390 divided by 91 is 4 with a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 7304.714
Subtract 364 from 390 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 10:
If we divide 260 by 91, we get 2 and a remainder of 78.
Write down 2 as next digit of the result. 
Result so far: 7304.7142
Subtracting 182 from 260 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Step 11:
When dividing 780 by 91, we get 8 with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 7304.71428
The remainder is 52 after subtracting 728 from 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 12:
When dividing 520 by 91, we get 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 7304.714285
Deduct 455 from 520 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Let's proceed to step 13:
When dividing 650 by 91, we get 7 with a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 7304.7142857
Deduct 637 from 650 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 14:
The number 91 fits into 130 1 times, leaving a remainder of 39.
Use 1 as the next digit of our solution. 
Result so far: 7304.71428571
If we subtract 91 from 130, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The quotient of the division is 7304.71428571, and the remainder is 3.9e-08.
