49719806 ÷ 58 
The aim is to understand the frequency of 58 in 49719806.

Step 1:
4 divided by 58 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 58

Moving on to step 2:
When dividing 49 by 58, we get 0 with a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 49, we end up with 49.
Grab the next digit (7) from the dividend, add it to 49, then carry on: 497 / 58

Going ahead to step 3:
The number 58 fits into 497 8 times, leaving a remainder of 33.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 464 from 497 to get 33.
Include the next digit (1) from the dividend after 33, then repeat: 331 / 58

Advancing to step 4:
If we divide 331 by 58, we get 5 and a remainder of 41.
Put 5 as the next digit of the answer. 
Result so far: 85.0
Subtract 290 from 331 to get 41.
Fetch the next digit (9) from the dividend, attach it to 41 and continue: 419 / 58

Advancing to step 5:
419 divided by 58 is 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 857.0
Subtract 406 from 419 to get 13.
Fetch the next digit (8) from the dividend, attach it to 13 and continue: 138 / 58

Step 6:
58 goes into 138 2 times with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 8572.0
The remainder is 22 after subtracting 116 from 138.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 58

Advancing to step 7:
58 can be fit into 220 3 times, resulting in a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 85723.0
Deduct 174 from 220 and we're left with 46.
Bring next digit (6) of the dividend behind the 46 and repeat the process: 466 / 58

Moving on to step 8:
The number 58 fits into 466 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 857238.0
If we subtract 464 from 466, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
The number 58 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 857238.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 10:
200 divided by 58 is 3 with a remainder of 26.
Write down 3 as next digit of the result. 
Result so far: 857238.03
If we subtract 174 from 200, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 11:
If we divide 260 by 58, we get 4 and a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 857238.034
Subtracting 232 from 260 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.

On to step 12:
58 goes into 280 4 times with a remainder of 48.
The next digit of our result is 4. 
Result so far: 857238.0344
If we subtract 232 from 280, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

The final outcome is 857238.0344, with a leftover of 0.00048.
