Let's divide 66639267 by 849
The aim is to understand the frequency of 849 in 66639267.

Let's proceed to step 1:
When dividing 6 by 849, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 849

Going ahead to step 2:
849 can be fit into 66 0 times, resulting in a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Bring next digit (6) of the dividend behind the 66 and repeat the process: 666 / 849

Step 3:
849 can be fit into 666 0 times, resulting in a remainder of 666.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 666 to get 666.
Fetch the next digit (3) from the dividend, attach it to 666 and continue: 6663 / 849

Moving on to step 4:
849 can be fit into 6663 7 times, resulting in a remainder of 720.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 5943 from 6663, we get 720.
Bring next digit (9) of the dividend behind the 720 and repeat the process: 7209 / 849

Going ahead to step 5:
The number 849 fits into 7209 8 times, leaving a remainder of 417.
Put 8 as the next digit of the answer. 
Result so far: 78.0
If we subtract 6792 from 7209, we get 417.
Grab the next digit (2) from the dividend, add it to 417, then carry on: 4172 / 849

Advancing to step 6:
849 can be fit into 4172 4 times, resulting in a remainder of 776.
Write down 4 as next digit of the result. 
Result so far: 784.0
Subtracting 3396 from 4172 leaves us with 776.
Grab the next digit (6) from the dividend, add it to 776, then carry on: 7766 / 849

Moving on to step 7:
If we divide 7766 by 849, we get 9 and a remainder of 125.
Record the quotient 9 as the next digit in the result. 
Result so far: 7849.0
If we subtract 7641 from 7766, we get 125.
Take the next digit (7) from the dividend and append it to 125, then repeat: 1257 / 849

Moving on to step 8:
849 goes into 1257 1 times with a remainder of 408.
Put 1 as the next digit of the answer. 
Result so far: 78491.0
The remainder is 408 after subtracting 849 from 1257.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Moving on to step 9:
The number 849 fits into 4080 4 times, leaving a remainder of 684.
Use 4 as the next digit of our solution. 
Result so far: 78491.4
If we subtract 3396 from 4080, we get 684.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6840, and continue the process.

On to step 10:
When dividing 6840 by 849, we get 8 with a remainder of 48.
The next digit of our result is 8. 
Result so far: 78491.48
Subtract 6792 from 6840 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 11:
849 can be fit into 480 0 times, resulting in a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 78491.48
Deduct 0 from 480 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Advancing to step 12:
849 goes into 4800 5 times with a remainder of 555.
Write down 5 as next digit of the result. 
Result so far: 78491.4805
If we take 4245 away from 4800, we end up with 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

On to step 13:
849 can be fit into 5550 6 times, resulting in a remainder of 456.
Put 6 as the next digit of the answer. 
Result so far: 78491.48056
The remainder is 456 after subtracting 5094 from 5550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

Advancing to step 14:
If we divide 4560 by 849, we get 5 and a remainder of 315.
The number 5 becomes the next digit in our result. 
Result so far: 78491.480565
Subtracting 4245 from 4560 leaves us with 315.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

On to step 15:
If we divide 3150 by 849, we get 3 and a remainder of 603.
Record the quotient 3 as the next digit in the result. 
Result so far: 78491.4805653
If we subtract 2547 from 3150, we get 603.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Moving on to step 16:
The number 849 fits into 6030 7 times, leaving a remainder of 87.
The number 7 becomes the next digit in our result. 
Result so far: 78491.48056537
Subtracting 5943 from 6030 leaves us with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

The final outcome is 78491.48056537, with a leftover of 8.7e-08.
