Let's divide 45339561 by 843
The aim is to understand the frequency of 843 in 45339561.

Advancing to step 1:
If we divide 4 by 843, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 843

On to step 2:
The number 843 fits into 45 0 times, leaving a remainder of 45.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 45 leaves us with 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 843

Step 3:
When dividing 453 by 843, we get 0 with a remainder of 453.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 453 after subtracting 0 from 453.
Include the next digit (3) from the dividend after 453, then repeat: 4533 / 843

Step 4:
843 can be fit into 4533 5 times, resulting in a remainder of 318.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 318 after subtracting 4215 from 4533.
Grab the next digit (9) from the dividend, add it to 318, then carry on: 3189 / 843

Going ahead to step 5:
843 can be fit into 3189 3 times, resulting in a remainder of 660.
Use 3 as the next digit of our solution. 
Result so far: 53.0
The remainder is 660 after subtracting 2529 from 3189.
Bring next digit (5) of the dividend behind the 660 and repeat the process: 6605 / 843

Moving on to step 6:
If we divide 6605 by 843, we get 7 and a remainder of 704.
Put 7 as the next digit of the answer. 
Result so far: 537.0
If we take 5901 away from 6605, we end up with 704.
Append the next digit (6) from the dividend to 704 and continue with: 7046 / 843

Step 7:
If we divide 7046 by 843, we get 8 and a remainder of 302.
Use 8 as the next digit of our solution. 
Result so far: 5378.0
If we subtract 6744 from 7046, we get 302.
Grab the next digit (1) from the dividend, add it to 302, then carry on: 3021 / 843

Going ahead to step 8:
When dividing 3021 by 843, we get 3 with a remainder of 492.
The next digit of our result is 3. 
Result so far: 53783.0
Subtract 2529 from 3021 to get 492.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4920, and continue the process.

Going ahead to step 9:
843 can be fit into 4920 5 times, resulting in a remainder of 705.
Record the quotient 5 as the next digit in the result. 
Result so far: 53783.5
Subtract 4215 from 4920 to get 705.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7050, and continue the process.

Advancing to step 10:
When dividing 7050 by 843, we get 8 with a remainder of 306.
Write down 8 as next digit of the result. 
Result so far: 53783.58
The remainder is 306 after subtracting 6744 from 7050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3060, and continue the process.

Step 11:
3060 divided by 843 is 3 with a remainder of 531.
Put 3 as the next digit of the answer. 
Result so far: 53783.583
Deduct 2529 from 3060 and we're left with 531.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5310, and continue the process.

On to step 12:
843 can be fit into 5310 6 times, resulting in a remainder of 252.
The number 6 becomes the next digit in our result. 
Result so far: 53783.5836
Deduct 5058 from 5310 and we're left with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

On to step 13:
843 goes into 2520 2 times with a remainder of 834.
Write down 2 as next digit of the result. 
Result so far: 53783.58362
If we take 1686 away from 2520, we end up with 834.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8340, and continue the process.

Let's proceed to step 14:
If we divide 8340 by 843, we get 9 and a remainder of 753.
The number 9 becomes the next digit in our result. 
Result so far: 53783.583629
If we take 7587 away from 8340, we end up with 753.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7530, and continue the process.

Advancing to step 15:
7530 divided by 843 is 8 with a remainder of 786.
The next digit of our result is 8. 
Result so far: 53783.5836298
Subtracting 6744 from 7530 leaves us with 786.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7860, and continue the process.

On to step 16:
When dividing 7860 by 843, we get 9 with a remainder of 273.
The next digit of our result is 9. 
Result so far: 53783.58362989
Subtracting 7587 from 7860 leaves us with 273.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2730, and continue the process.

Our division results in 53783.58362989 with a remaining 2.73e-07.
