We're dividing 12594707 by 348 
The aim is to understand the frequency of 348 in 12594707.

Step 1:
When dividing 1 by 348, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 348

On to step 2:
348 goes into 12 0 times with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 348

Moving on to step 3:
348 goes into 125 0 times with a remainder of 125.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 125 after subtracting 0 from 125.
Grab the next digit (9) from the dividend, add it to 125, then carry on: 1259 / 348

Going ahead to step 4:
When dividing 1259 by 348, we get 3 with a remainder of 215.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 1044 from 1259 leaves us with 215.
Append the next digit (4) from the dividend to 215 and continue with: 2154 / 348

Moving on to step 5:
348 goes into 2154 6 times with a remainder of 66.
Put 6 as the next digit of the answer. 
Result so far: 36.0
If we take 2088 away from 2154, we end up with 66.
Append the next digit (7) from the dividend to 66 and continue with: 667 / 348

Let's proceed to step 6:
If we divide 667 by 348, we get 1 and a remainder of 319.
The next digit of our result is 1. 
Result so far: 361.0
If we take 348 away from 667, we end up with 319.
Take the next digit (0) from the dividend and append it to 319, then repeat: 3190 / 348

Advancing to step 7:
348 can be fit into 3190 9 times, resulting in a remainder of 58.
Put 9 as the next digit of the answer. 
Result so far: 3619.0
Deduct 3132 from 3190 and we're left with 58.
Fetch the next digit (7) from the dividend, attach it to 58 and continue: 587 / 348

Advancing to step 8:
When dividing 587 by 348, we get 1 with a remainder of 239.
Put 1 as the next digit of the answer. 
Result so far: 36191.0
Deduct 348 from 587 and we're left with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Let's proceed to step 9:
2390 divided by 348 is 6 with a remainder of 302.
Record the quotient 6 as the next digit in the result. 
Result so far: 36191.6
Subtracting 2088 from 2390 leaves us with 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3020, and continue the process.

Step 10:
348 goes into 3020 8 times with a remainder of 236.
Use 8 as the next digit of our solution. 
Result so far: 36191.68
The remainder is 236 after subtracting 2784 from 3020.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

Moving on to step 11:
348 goes into 2360 6 times with a remainder of 272.
The number 6 becomes the next digit in our result. 
Result so far: 36191.686
If we take 2088 away from 2360, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 12:
If we divide 2720 by 348, we get 7 and a remainder of 284.
The next digit of our result is 7. 
Result so far: 36191.6867
The remainder is 284 after subtracting 2436 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Step 13:
348 goes into 2840 8 times with a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 36191.68678
If we take 2784 away from 2840, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 14:
If we divide 560 by 348, we get 1 and a remainder of 212.
The number 1 becomes the next digit in our result. 
Result so far: 36191.686781
Subtracting 348 from 560 leaves us with 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 15:
When dividing 2120 by 348, we get 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 36191.6867816
Deduct 2088 from 2120 and we're left 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.

On to step 16:
348 goes into 320 0 times with a remainder of 320.
The number 0 becomes the next digit in our result. 
Result so far: 36191.6867816
Subtract 0 from 320 to get 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3200, and continue the process.

The final outcome is 36191.6867816, with a leftover of 3.2e-07.
