We're dividing 66129400 by 848 
The aim is to understand the frequency of 848 in 66129400.

Moving on to step 1:
848 goes into 6 0 times 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.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 848

On to step 2:
848 goes into 66 0 times with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Take the next digit (1) from the dividend and append it to 66, then repeat: 661 / 848

Step 3:
848 goes into 661 0 times with a remainder of 661.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 661 leaves us with 661.
Append the next digit (2) from the dividend to 661 and continue with: 6612 / 848

Advancing to step 4:
848 can be fit into 6612 7 times, resulting in a remainder of 676.
The next digit of our result is 7. 
Result so far: 7.0
Deduct 5936 from 6612 and we're left with 676.
Append the next digit (9) from the dividend to 676 and continue with: 6769 / 848

On to step 5:
The number 848 fits into 6769 7 times, leaving a remainder of 833.
Record the quotient 7 as the next digit in the result. 
Result so far: 77.0
Subtracting 5936 from 6769 leaves us with 833.
Append the next digit (4) from the dividend to 833 and continue with: 8334 / 848

Step 6:
The number 848 fits into 8334 9 times, leaving a remainder of 702.
Write down 9 as next digit of the result. 
Result so far: 779.0
The remainder is 702 after subtracting 7632 from 8334.
Append the next digit (0) from the dividend to 702 and continue with: 7020 / 848

Step 7:
When dividing 7020 by 848, we get 8 with a remainder of 236.
Write down 8 as next digit of the result. 
Result so far: 7798.0
Subtracting 6784 from 7020 leaves us with 236.
Include the next digit (0) from the dividend after 236, then repeat: 2360 / 848

Going ahead to step 8:
The number 848 fits into 2360 2 times, leaving a remainder of 664.
The number 2 becomes the next digit in our result. 
Result so far: 77982.0
Deduct 1696 from 2360 and we're left with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Step 9:
6640 divided by 848 is 7 with a remainder of 704.
The next digit of our result is 7. 
Result so far: 77982.7
If we subtract 5936 from 6640, we get 704.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7040, and continue the process.

Going ahead to step 10:
7040 divided by 848 is 8 with a remainder of 256.
Put 8 as the next digit of the answer. 
Result so far: 77982.78
The remainder is 256 after subtracting 6784 from 7040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 11:
2560 divided by 848 is 3 with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 77982.783
Subtracting 2544 from 2560 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 12:
If we divide 160 by 848, we get 0 and a remainder of 160.
The next digit of our result is 0. 
Result so far: 77982.783
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 13:
848 can be fit into 1600 1 times, resulting in a remainder of 752.
The number 1 becomes the next digit in our result. 
Result so far: 77982.78301
If we take 848 away from 1600, we end up with 752.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7520, and continue the process.

Advancing to step 14:
When dividing 7520 by 848, we get 8 with a remainder of 736.
Put 8 as the next digit of the answer. 
Result so far: 77982.783018
Deduct 6784 from 7520 and we're left with 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Going ahead to step 15:
7360 divided by 848 is 8 with a remainder of 576.
Put 8 as the next digit of the answer. 
Result so far: 77982.7830188
If we subtract 6784 from 7360, we get 576.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5760, and continue the process.

The quotient of the division is 77982.7830188, and the remainder is 5.76e-06.
