646658 ÷ 58 
The aim is to understand the frequency of 58 in 646658.

Step 1:
58 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 58

On to step 2:
When dividing 64 by 58, we get 1 with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 58 from 64 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 58

Step 3:
58 can be fit into 66 1 times, resulting in a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 58 from 66, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 58

On to step 4:
The number 58 fits into 86 1 times, leaving a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 111.0
The remainder is 28 after subtracting 58 from 86.
Grab the next digit (5) from the dividend, add it to 28, then carry on: 285 / 58

Going ahead to step 5:
If we divide 285 by 58, we get 4 and a remainder of 53.
Record the quotient 4 as the next digit in the result. 
Result so far: 1114.0
The remainder is 53 after subtracting 232 from 285.
Include the next digit (8) from the dividend after 53, then repeat: 538 / 58

Advancing to step 6:
538 divided by 58 is 9 with a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 11149.0
If we take 522 away from 538, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
58 can be fit into 160 2 times, resulting in a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 11149.2
Subtracting 116 from 160 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 8:
If we divide 440 by 58, we get 7 and a remainder of 34.
The next digit of our result is 7. 
Result so far: 11149.27
Deduct 406 from 440 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 9:
When dividing 340 by 58, we get 5 with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 11149.275
Deduct 290 from 340 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 10:
When dividing 500 by 58, we get 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 11149.2758
If we take 464 away from 500, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
If we divide 360 by 58, we get 6 and a remainder of 12.
The next digit of our result is 6. 
Result so far: 11149.27586
Subtract 348 from 360 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
If we divide 120 by 58, we get 2 and a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 11149.275862
Deduct 116 from 120 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.

Let's proceed to step 13:
40 divided by 58 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 11149.275862
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
400 divided by 58 is 6 with a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 11149.27586206
If we take 348 away from 400, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

The final outcome is 11149.27586206, with a leftover of 5.2e-08.
