We're dividing 4108330 by 849 
The aim is to understand the frequency of 849 in 4108330.

On to step 1:
849 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 849

Step 2:
If we divide 41 by 849, we get 0 and a remainder of 41.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 41 after subtracting 0 from 41.
Bring next digit (0) of the dividend behind the 41 and repeat the process: 410 / 849

Moving on to step 3:
If we divide 410 by 849, we get 0 and a remainder of 410.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 410 leaves us with 410.
Include the next digit (8) from the dividend after 410, then repeat: 4108 / 849

On to step 4:
If we divide 4108 by 849, we get 4 and a remainder of 712.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 712 after subtracting 3396 from 4108.
Grab the next digit (3) from the dividend, add it to 712, then carry on: 7123 / 849

Going ahead to step 5:
7123 divided by 849 is 8 with a remainder of 331.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Subtract 6792 from 7123 to get 331.
Include the next digit (3) from the dividend after 331, then repeat: 3313 / 849

On to step 6:
When dividing 3313 by 849, we get 3 with a remainder of 766.
The number 3 becomes the next digit in our result. 
Result so far: 483.0
If we subtract 2547 from 3313, we get 766.
Fetch the next digit (0) from the dividend, attach it to 766 and continue: 7660 / 849

Going ahead to step 7:
The number 849 fits into 7660 9 times, leaving a remainder of 19.
Put 9 as the next digit of the answer. 
Result so far: 4839.0
Subtracting 7641 from 7660 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 8:
When dividing 190 by 849, we get 0 with a remainder of 190.
Use 0 as the next digit of our solution. 
Result so far: 4839.0
If we take 0 away from 190, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Moving on to step 9:
1900 divided by 849 is 2 with a remainder of 202.
The number 2 becomes the next digit in our result. 
Result so far: 4839.02
Deduct 1698 from 1900 and we're left with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

On to step 10:
849 can be fit into 2020 2 times, resulting in a remainder of 322.
Record the quotient 2 as the next digit in the result. 
Result so far: 4839.022
Deduct 1698 from 2020 and we're left with 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

The quotient of the division is 4839.022, and the remainder is 0.0322.
