16542946 ÷ 348 
The aim is to understand the frequency of 348 in 16542946.

Advancing to step 1:
When dividing 1 by 348, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 348

Moving on to step 2:
When dividing 16 by 348, we get 0 with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 348

Going ahead to step 3:
348 goes into 165 0 times with a remainder of 165.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 165 after subtracting 0 from 165.
Include the next digit (4) from the dividend after 165, then repeat: 1654 / 348

Going ahead to step 4:
348 can be fit into 1654 4 times, resulting in a remainder of 262.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 1392 away from 1654, we end up with 262.
Grab the next digit (2) from the dividend, add it to 262, then carry on: 2622 / 348

Step 5:
When dividing 2622 by 348, we get 7 with a remainder of 186.
Record the quotient 7 as the next digit in the result. 
Result so far: 47.0
Deduct 2436 from 2622 and we're left with 186.
Append the next digit (9) from the dividend to 186 and continue with: 1869 / 348

Going ahead to step 6:
If we divide 1869 by 348, we get 5 and a remainder of 129.
The number 5 becomes the next digit in our result. 
Result so far: 475.0
If we take 1740 away from 1869, we end up with 129.
Include the next digit (4) from the dividend after 129, then repeat: 1294 / 348

Going ahead to step 7:
When dividing 1294 by 348, we get 3 with a remainder of 250.
The next digit of our result is 3. 
Result so far: 4753.0
If we take 1044 away from 1294, we end up with 250.
Append the next digit (6) from the dividend to 250 and continue with: 2506 / 348

Let's proceed to step 8:
348 goes into 2506 7 times with a remainder of 70.
Put 7 as the next digit of the answer. 
Result so far: 47537.0
Subtract 2436 from 2506 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
The number 348 fits into 700 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 47537.2
Deduct 696 from 700 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 10:
The number 348 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 47537.2
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
400 divided by 348 is 1 with a remainder of 52.
Write down 1 as next digit of the result. 
Result so far: 47537.201
Subtract 348 from 400 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 12:
520 divided by 348 is 1 with a remainder of 172.
The next digit of our result is 1. 
Result so far: 47537.2011
Deduct 348 from 520 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

After the division, we end up with 47537.2011 and a remainder of 0.00172.
