We divide 54943157 by 12
The aim is to understand the frequency of 12 in 54943157.

Moving on to step 1:
If we divide 5 by 12, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 12

On to step 2:
If we divide 54 by 12, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 48 from 54, we get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 12

Moving on to step 3:
If we divide 69 by 12, we get 5 and a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 45.0
The remainder is 9 after subtracting 60 from 69.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 12

Step 4:
When dividing 94 by 12, we get 7 with a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 457.0
Subtracting 84 from 94 leaves us with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 12

Step 5:
12 can be fit into 103 8 times, resulting in a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 4578.0
Subtracting 96 from 103 leaves us with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 12

On to step 6:
12 can be fit into 71 5 times, resulting in a remainder of 11.
Put 5 as the next digit of the answer. 
Result so far: 45785.0
Subtract 60 from 71 to get 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 12

Moving on to step 7:
When dividing 115 by 12, we get 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 457859.0
Subtracting 108 from 115 leaves us with 7.
Append the next digit (7) from the dividend to 7 and continue with: 77 / 12

On to step 8:
77 divided by 12 is 6 with a remainder of 5.
The next digit of our result is 6. 
Result so far: 4578596.0
Subtracting 72 from 77 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
12 can be fit into 50 4 times, resulting in a remainder of 2.
The next digit of our result is 4. 
Result so far: 4578596.4
Deduct 48 from 50 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
When dividing 20 by 12, we get 1 with a remainder of 8.
The next digit of our result is 1. 
Result so far: 4578596.41
Subtract 12 from 20 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
When dividing 80 by 12, we get 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 4578596.416
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 4578596.4166
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 4578596.4166, with a leftover of 8e-05.
