20122178 ÷ 943 
The aim is to understand the frequency of 943 in 20122178.

Let's proceed to step 1:
943 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 943

Going ahead to step 2:
If we divide 20 by 943, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Include the next digit (1) from the dividend after 20, then repeat: 201 / 943

Step 3:
If we divide 201 by 943, we get 0 and a remainder of 201.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 201 to get 201.
Include the next digit (2) from the dividend after 201, then repeat: 2012 / 943

Going ahead to step 4:
943 goes into 2012 2 times with a remainder of 126.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 1886 from 2012 and we're left with 126.
Include the next digit (2) from the dividend after 126, then repeat: 1262 / 943

Going ahead to step 5:
The number 943 fits into 1262 1 times, leaving a remainder of 319.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Deduct 943 from 1262 and we're left with 319.
Bring next digit (1) of the dividend behind the 319 and repeat the process: 3191 / 943

Advancing to step 6:
943 goes into 3191 3 times with a remainder of 362.
The next digit of our result is 3. 
Result so far: 213.0
The remainder is 362 after subtracting 2829 from 3191.
Bring next digit (7) of the dividend behind the 362 and repeat the process: 3627 / 943

Moving on to step 7:
3627 divided by 943 is 3 with a remainder of 798.
Use 3 as the next digit of our solution. 
Result so far: 2133.0
Subtract 2829 from 3627 to get 798.
Append the next digit (8) from the dividend to 798 and continue with: 7988 / 943

On to step 8:
The number 943 fits into 7988 8 times, leaving a remainder of 444.
Write down 8 as next digit of the result. 
Result so far: 21338.0
Deduct 7544 from 7988 and we're left with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Moving on to step 9:
943 goes into 4440 4 times with a remainder of 668.
The number 4 becomes the next digit in our result. 
Result so far: 21338.4
Deduct 3772 from 4440 and we're left with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

Let's proceed to step 10:
6680 divided by 943 is 7 with a remainder of 79.
Write down 7 as next digit of the result. 
Result so far: 21338.47
The remainder is 79 after subtracting 6601 from 6680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Going ahead to step 11:
943 can be fit into 790 0 times, resulting in a remainder of 790.
Put 0 as the next digit of the answer. 
Result so far: 21338.47
The remainder is 790 after subtracting 0 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Moving on to step 12:
7900 divided by 943 is 8 with a remainder of 356.
Write down 8 as next digit of the result. 
Result so far: 21338.4708
If we subtract 7544 from 7900, we get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Advancing to step 13:
When dividing 3560 by 943, we get 3 with a remainder of 731.
Put 3 as the next digit of the answer. 
Result so far: 21338.47083
Deduct 2829 from 3560 and we're left with 731.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7310, and continue the process.

Moving on to step 14:
If we divide 7310 by 943, we get 7 and a remainder of 709.
The number 7 becomes the next digit in our result. 
Result so far: 21338.470837
The remainder is 709 after subtracting 6601 from 7310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

Step 15:
943 goes into 7090 7 times with a remainder of 489.
The next digit of our result is 7. 
Result so far: 21338.4708377
Subtract 6601 from 7090 to get 489.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4890, and continue the process.

Our division results in 21338.4708377 with a remaining 4.89e-06.
