18015779 ÷ 943 
The aim is to understand the frequency of 943 in 18015779.

Moving on to step 1:
If we divide 1 by 943, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 943

Moving on to step 2:
18 divided by 943 is 0 with a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 18 after subtracting 0 from 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 943

On to step 3:
180 divided by 943 is 0 with a remainder of 180.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 180, we end up with 180.
Append the next digit (1) from the dividend to 180 and continue with: 1801 / 943

Let's proceed to step 4:
When dividing 1801 by 943, we get 1 with a remainder of 858.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 943 from 1801 leaves us with 858.
Fetch the next digit (5) from the dividend, attach it to 858 and continue: 8585 / 943

Moving on to step 5:
When dividing 8585 by 943, we get 9 with a remainder of 98.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we take 8487 away from 8585, we end up with 98.
Append the next digit (7) from the dividend to 98 and continue with: 987 / 943

Moving on to step 6:
If we divide 987 by 943, we get 1 and a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 191.0
If we subtract 943 from 987, we get 44.
Include the next digit (7) from the dividend after 44, then repeat: 447 / 943

Going ahead to step 7:
447 divided by 943 is 0 with a remainder of 447.
Use 0 as the next digit of our solution. 
Result so far: 1910.0
If we take 0 away from 447, we end up with 447.
Bring next digit (9) of the dividend behind the 447 and repeat the process: 4479 / 943

Moving on to step 8:
4479 divided by 943 is 4 with a remainder of 707.
Put 4 as the next digit of the answer. 
Result so far: 19104.0
Deduct 3772 from 4479 and we're left with 707.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7070, and continue the process.

On to step 9:
7070 divided by 943 is 7 with a remainder of 469.
Put 7 as the next digit of the answer. 
Result so far: 19104.7
If we take 6601 away from 7070, we end up with 469.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4690, and continue the process.

Moving on to step 10:
The number 943 fits into 4690 4 times, leaving a remainder of 918.
The next digit of our result is 4. 
Result so far: 19104.74
The remainder is 918 after subtracting 3772 from 4690.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9180, and continue the process.

On to step 11:
943 goes into 9180 9 times with a remainder of 693.
The next digit of our result is 9. 
Result so far: 19104.749
If we subtract 8487 from 9180, we get 693.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6930, and continue the process.

Step 12:
The number 943 fits into 6930 7 times, leaving a remainder of 329.
Use 7 as the next digit of our solution. 
Result so far: 19104.7497
If we subtract 6601 from 6930, we get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

On to step 13:
If we divide 3290 by 943, we get 3 and a remainder of 461.
The number 3 becomes the next digit in our result. 
Result so far: 19104.74973
If we subtract 2829 from 3290, we get 461.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4610, and continue the process.

Moving on to step 14:
943 goes into 4610 4 times with a remainder of 838.
The number 4 becomes the next digit in our result. 
Result so far: 19104.749734
If we take 3772 away from 4610, we end up with 838.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8380, and continue the process.

Moving on to step 15:
943 can be fit into 8380 8 times, resulting in a remainder of 836.
Record the quotient 8 as the next digit in the result. 
Result so far: 19104.7497348
Subtract 7544 from 8380 to get 836.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8360, and continue the process.

Going ahead to step 16:
When dividing 8360 by 943, we get 8 with a remainder of 816.
Write down 8 as next digit of the result. 
Result so far: 19104.74973488
If we take 7544 away from 8360, we end up with 816.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8160, and continue the process.

After the division, we end up with 19104.74973488 and a remainder of 8.16e-07.
