We're dividing 434119 by 12 
The aim is to understand the frequency of 12 in 434119.

Step 1:
12 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 12

Moving on to step 2:
When dividing 43 by 12, we get 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 36 from 43 and we're left with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 12

On to step 3:
12 goes into 74 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 36.0
Subtracting 72 from 74 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 12

Moving on to step 4:
If we divide 21 by 12, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 361.0
If we subtract 12 from 21, we get 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 12

Step 5:
91 divided by 12 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 3617.0
If we subtract 84 from 91, we get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 12

Going ahead to step 6:
79 divided by 12 is 6 with a remainder of 7.
Put 6 as the next digit of the answer. 
Result so far: 36176.0
If we take 72 away from 79, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
If we divide 70 by 12, we get 5 and a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 36176.5
Deduct 60 from 70 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 12 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 36176.58
Deduct 96 from 100 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 36176.583
If we take 36 away from 40, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 36176.5833
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 36176.5833 with a remaining 4e-05.
