623403 divided by 58 
The aim is to understand the frequency of 58 in 623403.

Step 1:
58 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 58

Moving on to step 2:
58 can be fit into 62 1 times, resulting in a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 58 from 62, we get 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 58

Let's proceed to step 3:
58 goes into 43 0 times with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 43 and we're left with 43.
Take the next digit (4) from the dividend and append it to 43, then repeat: 434 / 58

Step 4:
The number 58 fits into 434 7 times, leaving a remainder of 28.
Write down 7 as next digit of the result. 
Result so far: 107.0
If we take 406 away from 434, we end up with 28.
Append the next digit (0) from the dividend to 28 and continue with: 280 / 58

Let's proceed to step 5:
280 divided by 58 is 4 with a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 1074.0
The remainder is 48 after subtracting 232 from 280.
Fetch the next digit (3) from the dividend, attach it to 48 and continue: 483 / 58

Advancing to step 6:
The number 58 fits into 483 8 times, leaving a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 10748.0
If we subtract 464 from 483, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 7:
When dividing 190 by 58, we get 3 with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 10748.3
If we take 174 away from 190, 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.

Advancing to step 8:
58 can be fit into 160 2 times, resulting in a remainder of 44.
The next digit of our result is 2. 
Result so far: 10748.32
Deduct 116 from 160 and we're left 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.

Advancing to step 9:
The number 58 fits into 440 7 times, leaving a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 10748.327
Subtract 406 from 440 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
If we divide 340 by 58, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 10748.3275
If we subtract 290 from 340, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 11:
If we divide 500 by 58, we get 8 and a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 10748.32758
Deduct 464 from 500 and we're left 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.

On to step 12:
58 goes into 360 6 times with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 10748.327586
The remainder is 12 after subtracting 348 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
120 divided by 58 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 10748.3275862
If we subtract 116 from 120, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
40 divided by 58 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 10748.3275862
If we subtract 0 from 40, we 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.

After the division, we end up with 10748.3275862 and a remainder of 4e-08.
