58872139 ÷ 348 
The aim is to understand the frequency of 348 in 58872139.

Advancing to step 1:
348 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 348

Advancing to step 2:
58 divided by 348 is 0 with a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 58 to get 58.
Include the next digit (8) from the dividend after 58, then repeat: 588 / 348

Step 3:
588 divided by 348 is 1 with a remainder of 240.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 348 from 588 and we're left with 240.
Include the next digit (7) from the dividend after 240, then repeat: 2407 / 348

Advancing to step 4:
348 goes into 2407 6 times with a remainder of 319.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we take 2088 away from 2407, we end up with 319.
Append the next digit (2) from the dividend to 319 and continue with: 3192 / 348

Going ahead to step 5:
348 goes into 3192 9 times with a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 169.0
Subtract 3132 from 3192 to get 60.
Include the next digit (1) from the dividend after 60, then repeat: 601 / 348

Advancing to step 6:
If we divide 601 by 348, we get 1 and a remainder of 253.
Put 1 as the next digit of the answer. 
Result so far: 1691.0
Subtracting 348 from 601 leaves us with 253.
Grab the next digit (3) from the dividend, add it to 253, then carry on: 2533 / 348

Moving on to step 7:
2533 divided by 348 is 7 with a remainder of 97.
Use 7 as the next digit of our solution. 
Result so far: 16917.0
Subtract 2436 from 2533 to get 97.
Take the next digit (9) from the dividend and append it to 97, then repeat: 979 / 348

Let's proceed to step 8:
348 can be fit into 979 2 times, resulting in a remainder of 283.
Put 2 as the next digit of the answer. 
Result so far: 169172.0
Deduct 696 from 979 and we're left with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

On to step 9:
The number 348 fits into 2830 8 times, leaving a remainder of 46.
Write down 8 as next digit of the result. 
Result so far: 169172.8
Deduct 2784 from 2830 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 10:
If we divide 460 by 348, we get 1 and a remainder of 112.
The number 1 becomes the next digit in our result. 
Result so far: 169172.81
Subtract 348 from 460 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 11:
1120 divided by 348 is 3 with a remainder of 76.
Record the quotient 3 as the next digit in the result. 
Result so far: 169172.813
If we subtract 1044 from 1120, we 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.

Moving on to step 12:
760 divided by 348 is 2 with a remainder of 64.
Record the quotient 2 as the next digit in the result. 
Result so far: 169172.8132
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.

Moving on to step 13:
348 goes into 640 1 times with a remainder of 292.
Write down 1 as next digit of the result. 
Result so far: 169172.81321
The remainder is 292 after subtracting 348 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Let's proceed to step 14:
The number 348 fits into 2920 8 times, leaving a remainder of 136.
Put 8 as the next digit of the answer. 
Result so far: 169172.813218
If we take 2784 away from 2920, we end up with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

On to step 15:
348 can be fit into 1360 3 times, resulting in a remainder of 316.
Put 3 as the next digit of the answer. 
Result so far: 169172.8132183
Subtracting 1044 from 1360 leaves us with 316.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

Going ahead to step 16:
If we divide 3160 by 348, we get 9 and a remainder of 28.
The next digit of our result is 9. 
Result so far: 169172.81321839
Subtracting 3132 from 3160 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The final outcome is 169172.81321839, with a leftover of 2.8e-08.
