84135351 ÷ 943 
The aim is to understand the frequency of 943 in 84135351.

Let's proceed to step 1:
8 divided by 943 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 943

Moving on to step 2:
If we divide 84 by 943, we get 0 and a remainder of 84.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 84 and we're left with 84.
Append the next digit (1) from the dividend to 84 and continue with: 841 / 943

Advancing to step 3:
When dividing 841 by 943, we get 0 with a remainder of 841.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 841 to get 841.
Include the next digit (3) from the dividend after 841, then repeat: 8413 / 943

Advancing to step 4:
943 goes into 8413 8 times with a remainder of 869.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 7544 from 8413 to get 869.
Bring next digit (5) of the dividend behind the 869 and repeat the process: 8695 / 943

On to step 5:
When dividing 8695 by 943, we get 9 with a remainder of 208.
The number 9 becomes the next digit in our result. 
Result so far: 89.0
Subtract 8487 from 8695 to get 208.
Grab the next digit (3) from the dividend, add it to 208, then carry on: 2083 / 943

Going ahead to step 6:
When dividing 2083 by 943, we get 2 with a remainder of 197.
Use 2 as the next digit of our solution. 
Result so far: 892.0
Subtracting 1886 from 2083 leaves us with 197.
Take the next digit (5) from the dividend and append it to 197, then repeat: 1975 / 943

Going ahead to step 7:
1975 divided by 943 is 2 with a remainder of 89.
Use 2 as the next digit of our solution. 
Result so far: 8922.0
If we subtract 1886 from 1975, we get 89.
Fetch the next digit (1) from the dividend, attach it to 89 and continue: 891 / 943

Step 8:
891 divided by 943 is 0 with a remainder of 891.
Record the quotient 0 as the next digit in the result. 
Result so far: 89220.0
Deduct 0 from 891 and we're left with 891.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8910, and continue the process.

On to step 9:
If we divide 8910 by 943, we get 9 and a remainder of 423.
Put 9 as the next digit of the answer. 
Result so far: 89220.9
Deduct 8487 from 8910 and we're left with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

On to step 10:
When dividing 4230 by 943, we get 4 with a remainder of 458.
The next digit of our result is 4. 
Result so far: 89220.94
The remainder is 458 after subtracting 3772 from 4230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4580, and continue the process.

Moving on to step 11:
943 can be fit into 4580 4 times, resulting in a remainder of 808.
Put 4 as the next digit of the answer. 
Result so far: 89220.944
Deduct 3772 from 4580 and we're left with 808.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8080, and continue the process.

After the division, we end up with 89220.944 and a remainder of 0.0808.
