We look at the division of 50847611 by 943 
The aim is to understand the frequency of 943 in 50847611.

Advancing to step 1:
5 divided by 943 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 943

On to step 2:
When dividing 50 by 943, we get 0 with a remainder of 50.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 50 leaves us with 50.
Take the next digit (8) from the dividend and append it to 50, then repeat: 508 / 943

Moving on to step 3:
943 goes into 508 0 times with a remainder of 508.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 508, we get 508.
Take the next digit (4) from the dividend and append it to 508, then repeat: 5084 / 943

Step 4:
If we divide 5084 by 943, we get 5 and a remainder of 369.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 4715 from 5084, we get 369.
Take the next digit (7) from the dividend and append it to 369, then repeat: 3697 / 943

On to step 5:
If we divide 3697 by 943, we get 3 and a remainder of 868.
Write down 3 as next digit of the result. 
Result so far: 53.0
The remainder is 868 after subtracting 2829 from 3697.
Grab the next digit (6) from the dividend, add it to 868, then carry on: 8686 / 943

Let's proceed to step 6:
8686 divided by 943 is 9 with a remainder of 199.
The next digit of our result is 9. 
Result so far: 539.0
Subtract 8487 from 8686 to get 199.
Append the next digit (1) from the dividend to 199 and continue with: 1991 / 943

On to step 7:
943 goes into 1991 2 times with a remainder of 105.
The number 2 becomes the next digit in our result. 
Result so far: 5392.0
Subtracting 1886 from 1991 leaves us with 105.
Grab the next digit (1) from the dividend, add it to 105, then carry on: 1051 / 943

Moving on to step 8:
943 goes into 1051 1 times with a remainder of 108.
Record the quotient 1 as the next digit in the result. 
Result so far: 53921.0
The remainder is 108 after subtracting 943 from 1051.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Moving on to step 9:
When dividing 1080 by 943, we get 1 with a remainder of 137.
The number 1 becomes the next digit in our result. 
Result so far: 53921.1
Subtract 943 from 1080 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 10:
943 can be fit into 1370 1 times, resulting in a remainder of 427.
Record the quotient 1 as the next digit in the result. 
Result so far: 53921.11
Deduct 943 from 1370 and we're left with 427.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4270, and continue the process.

After the division, we end up with 53921.11 and a remainder of 0.427.
