401660 divided by 34 
The aim is to understand the frequency of 34 in 401660.

Let's proceed to step 1:
If we divide 4 by 34, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 34

Let's proceed to step 2:
34 goes into 40 1 times with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 34 from 40, we get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 34

Let's proceed to step 3:
The number 34 fits into 61 1 times, leaving a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 34 away from 61, we end up with 27.
Take the next digit (6) from the dividend and append it to 27, then repeat: 276 / 34

Moving on to step 4:
276 divided by 34 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 118.0
Subtracting 272 from 276 leaves us with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 34

Step 5:
The number 34 fits into 46 1 times, leaving a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 1181.0
If we subtract 34 from 46, we get 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 34

Step 6:
120 divided by 34 is 3 with a remainder of 18.
The next digit of our result is 3. 
Result so far: 11813.0
If we subtract 102 from 120, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
When dividing 180 by 34, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 11813.5
If we subtract 170 from 180, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
34 goes into 100 2 times with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 11813.52
Subtracting 68 from 100 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 9:
34 can be fit into 320 9 times, resulting in a remainder of 14.
Record the quotient 9 as the next digit in the result. 
Result so far: 11813.529
If we subtract 306 from 320, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 10:
The number 34 fits into 140 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 11813.5294
Subtracting 136 from 140 leaves us 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.

Let's proceed to step 11:
40 divided by 34 is 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 11813.52941
Deduct 34 from 40 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
34 can be fit into 60 1 times, resulting in a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 11813.529411
Deduct 34 from 60 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

In conclusion, the division gives 11813.529411 with a balance of 2.6e-06.
