512420 ÷ 34 
The aim is to understand the frequency of 34 in 512420.

Moving on to step 1:
When dividing 5 by 34, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 34

Going ahead to step 2:
The number 34 fits into 51 1 times, leaving a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 34 from 51 leaves us with 17.
Grab the next digit (2) from the dividend, add it to 17, then carry on: 172 / 34

On to step 3:
34 can be fit into 172 5 times, resulting in a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 170 from 172 to get 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 34

Let's proceed to step 4:
When dividing 24 by 34, we get 0 with a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 150.0
If we subtract 0 from 24, we get 24.
Bring next digit (2) of the dividend behind the 24 and repeat the process: 242 / 34

Advancing to step 5:
The number 34 fits into 242 7 times, leaving a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 1507.0
The remainder is 4 after subtracting 238 from 242.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 34

Moving on to step 6:
When dividing 40 by 34, we get 1 with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 15071.0
Subtract 34 from 40 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
The number 34 fits into 60 1 times, leaving a remainder of 26.
The number 1 becomes the next digit in our result. 
Result so far: 15071.1
Subtract 34 from 60 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 8:
The number 34 fits into 260 7 times, leaving a remainder of 22.
Record the quotient 7 as the next digit in the result. 
Result so far: 15071.17
Deduct 238 from 260 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
The number 34 fits into 220 6 times, leaving a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 15071.176
Subtract 204 from 220 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
If we divide 160 by 34, we get 4 and a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 15071.1764
Deduct 136 from 160 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 11:
34 goes into 240 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 15071.17647
Subtracting 238 from 240 leaves us 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.

Advancing to step 12:
34 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 15071.17647
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
When dividing 200 by 34, we get 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 15071.1764705
Deduct 170 from 200 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 14:
When dividing 300 by 34, we get 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 15071.17647058
The remainder is 28 after subtracting 272 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 15071.17647058, and the remainder is 2.8e-08.
