We look at the division of 1616038 by 348 
The aim is to understand the frequency of 348 in 1616038.

Step 1:
The number 348 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 348

Going ahead to step 2:
The number 348 fits into 16 0 times, leaving a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Include the next digit (1) from the dividend after 16, then repeat: 161 / 348

Let's proceed to step 3:
161 divided by 348 is 0 with a remainder of 161.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 161 leaves us with 161.
Append the next digit (6) from the dividend to 161 and continue with: 1616 / 348

Step 4:
If we divide 1616 by 348, we get 4 and a remainder of 224.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 1392 away from 1616, we end up with 224.
Grab the next digit (0) from the dividend, add it to 224, then carry on: 2240 / 348

Let's proceed to step 5:
348 goes into 2240 6 times with a remainder of 152.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
If we take 2088 away from 2240, we end up with 152.
Take the next digit (3) from the dividend and append it to 152, then repeat: 1523 / 348

Going ahead to step 6:
The number 348 fits into 1523 4 times, leaving a remainder of 131.
Record the quotient 4 as the next digit in the result. 
Result so far: 464.0
If we subtract 1392 from 1523, we get 131.
Fetch the next digit (8) from the dividend, attach it to 131 and continue: 1318 / 348

On to step 7:
348 can be fit into 1318 3 times, resulting in a remainder of 274.
Write down 3 as next digit of the result. 
Result so far: 4643.0
The remainder is 274 after subtracting 1044 from 1318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 8:
348 goes into 2740 7 times with a remainder of 304.
The next digit of our result is 7. 
Result so far: 4643.7
Subtracting 2436 from 2740 leaves us with 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

On to step 9:
348 goes into 3040 8 times with a remainder of 256.
Record the quotient 8 as the next digit in the result. 
Result so far: 4643.78
If we take 2784 away from 3040, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 10:
348 goes into 2560 7 times with a remainder of 124.
The number 7 becomes the next digit in our result. 
Result so far: 4643.787
Subtract 2436 from 2560 to get 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Step 11:
348 can be fit into 1240 3 times, resulting in a remainder of 196.
Use 3 as the next digit of our solution. 
Result so far: 4643.7873
Deduct 1044 from 1240 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 12:
348 can be fit into 1960 5 times, resulting in a remainder of 220.
The next digit of our result is 5. 
Result so far: 4643.78735
If we take 1740 away from 1960, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Going ahead to step 13:
348 goes into 2200 6 times with a remainder of 112.
Use 6 as the next digit of our solution. 
Result so far: 4643.787356
The remainder is 112 after subtracting 2088 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

On to step 14:
The number 348 fits into 1120 3 times, leaving a remainder of 76.
The number 3 becomes the next digit in our result. 
Result so far: 4643.7873563
Subtract 1044 from 1120 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 15:
When dividing 760 by 348, we get 2 with a remainder of 64.
The next digit of our result is 2. 
Result so far: 4643.78735632
If we take 696 away from 760, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 4643.78735632, with a leftover of 6.4e-08.
