646497 divided by 94 
The aim is to understand the frequency of 94 in 646497.

On to step 1:
6 divided by 94 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 94

On to step 2:
When dividing 64 by 94, we get 0 with a remainder of 64.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Include the next digit (6) from the dividend after 64, then repeat: 646 / 94

Moving on to step 3:
If we divide 646 by 94, we get 6 and a remainder of 82.
The next digit of our result is 6. 
Result so far: 6.0
Subtracting 564 from 646 leaves us with 82.
Grab the next digit (4) from the dividend, add it to 82, then carry on: 824 / 94

Going ahead to step 4:
94 can be fit into 824 8 times, resulting in a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 68.0
Deduct 752 from 824 and we're left with 72.
Append the next digit (9) from the dividend to 72 and continue with: 729 / 94

Let's proceed to step 5:
94 can be fit into 729 7 times, resulting in a remainder of 71.
Write down 7 as next digit of the result. 
Result so far: 687.0
Subtracting 658 from 729 leaves us with 71.
Bring next digit (7) of the dividend behind the 71 and repeat the process: 717 / 94

Step 6:
The number 94 fits into 717 7 times, leaving a remainder of 59.
The number 7 becomes the next digit in our result. 
Result so far: 6877.0
Deduct 658 from 717 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 7:
94 can be fit into 590 6 times, resulting in a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 6877.6
The remainder is 26 after subtracting 564 from 590.
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 8:
94 can be fit into 260 2 times, resulting in a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 6877.62
Deduct 188 from 260 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 9:
When dividing 720 by 94, we get 7 with a remainder of 62.
Record the quotient 7 as the next digit in the result. 
Result so far: 6877.627
Subtract 658 from 720 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 10:
If we divide 620 by 94, we get 6 and a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 6877.6276
The remainder is 56 after subtracting 564 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 11:
560 divided by 94 is 5 with a remainder of 90.
Use 5 as the next digit of our solution. 
Result so far: 6877.62765
If we take 470 away from 560, we end up with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Step 12:
900 divided by 94 is 9 with a remainder of 54.
The number 9 becomes the next digit in our result. 
Result so far: 6877.627659
The remainder is 54 after subtracting 846 from 900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 13:
94 can be fit into 540 5 times, resulting in a remainder of 70.
The next digit of our result is 5. 
Result so far: 6877.6276595
The remainder is 70 after subtracting 470 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 14:
700 divided by 94 is 7 with a remainder of 42.
Put 7 as the next digit of the answer. 
Result so far: 6877.62765957
Subtracting 658 from 700 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 6877.62765957 with a remaining 4.2e-08.
