Let's divide 66878110 by 849
The aim is to understand the frequency of 849 in 66878110.

Going ahead to step 1:
If we divide 6 by 849, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 849

Moving on to step 2:
849 goes into 66 0 times with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Fetch the next digit (8) from the dividend, attach it to 66 and continue: 668 / 849

Let's proceed to step 3:
If we divide 668 by 849, we get 0 and a remainder of 668.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 668 after subtracting 0 from 668.
Append the next digit (7) from the dividend to 668 and continue with: 6687 / 849

Let's proceed to step 4:
The number 849 fits into 6687 7 times, leaving a remainder of 744.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 5943 from 6687, we get 744.
Bring next digit (8) of the dividend behind the 744 and repeat the process: 7448 / 849

Moving on to step 5:
849 goes into 7448 8 times with a remainder of 656.
Write down 8 as next digit of the result. 
Result so far: 78.0
Subtract 6792 from 7448 to get 656.
Include the next digit (1) from the dividend after 656, then repeat: 6561 / 849

Moving on to step 6:
6561 divided by 849 is 7 with a remainder of 618.
Use 7 as the next digit of our solution. 
Result so far: 787.0
Subtract 5943 from 6561 to get 618.
Bring next digit (1) of the dividend behind the 618 and repeat the process: 6181 / 849

Step 7:
6181 divided by 849 is 7 with a remainder of 238.
The number 7 becomes the next digit in our result. 
Result so far: 7877.0
If we take 5943 away from 6181, we end up with 238.
Grab the next digit (0) from the dividend, add it to 238, then carry on: 2380 / 849

Let's proceed to step 8:
849 goes into 2380 2 times with a remainder of 682.
Use 2 as the next digit of our solution. 
Result so far: 78772.0
Subtract 1698 from 2380 to get 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

Let's proceed to step 9:
The number 849 fits into 6820 8 times, leaving a remainder of 28.
The next digit of our result is 8. 
Result so far: 78772.8
Subtract 6792 from 6820 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
280 divided by 849 is 0 with a remainder of 280.
Record the quotient 0 as the next digit in the result. 
Result so far: 78772.8
If we take 0 away from 280, we end up with 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2800, and continue the process.

Step 11:
2800 divided by 849 is 3 with a remainder of 253.
Put 3 as the next digit of the answer. 
Result so far: 78772.803
Subtracting 2547 from 2800 leaves us with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Moving on to step 12:
The number 849 fits into 2530 2 times, leaving a remainder of 832.
Record the quotient 2 as the next digit in the result. 
Result so far: 78772.8032
Subtracting 1698 from 2530 leaves us with 832.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8320, and continue the process.

Let's proceed to step 13:
849 can be fit into 8320 9 times, resulting in a remainder of 679.
Put 9 as the next digit of the answer. 
Result so far: 78772.80329
Subtract 7641 from 8320 to get 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Moving on to step 14:
849 goes into 6790 7 times with a remainder of 847.
The next digit of our result is 7. 
Result so far: 78772.803297
The remainder is 847 after subtracting 5943 from 6790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8470, and continue the process.

Advancing to step 15:
If we divide 8470 by 849, we get 9 and a remainder of 829.
The next digit of our result is 9. 
Result so far: 78772.8032979
Subtract 7641 from 8470 to get 829.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8290, and continue the process.

Step 16:
When dividing 8290 by 849, we get 9 with a remainder of 649.
Write down 9 as next digit of the result. 
Result so far: 78772.80329799
Deduct 7641 from 8290 and we're left with 649.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6490, and continue the process.

The quotient of the division is 78772.80329799, and the remainder is 6.49e-07.
