We're dividing 753900 by 58 
The aim is to understand the frequency of 58 in 753900.

Step 1:
58 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (5) from the dividend, add it to 7, then carry on: 75 / 58

On to step 2:
If we divide 75 by 58, we get 1 and a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 58 from 75 leaves us with 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 58

Advancing to step 3:
The number 58 fits into 173 2 times, leaving a remainder of 57.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 57 after subtracting 116 from 173.
Take the next digit (9) from the dividend and append it to 57, then repeat: 579 / 58

Step 4:
579 divided by 58 is 9 with a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 129.0
If we subtract 522 from 579, we get 57.
Grab the next digit (0) from the dividend, add it to 57, then carry on: 570 / 58

On to step 5:
58 can be fit into 570 9 times, resulting in a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 1299.0
Subtract 522 from 570 to get 48.
Append the next digit (0) from the dividend to 48 and continue with: 480 / 58

Advancing to step 6:
58 goes into 480 8 times with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 12998.0
Deduct 464 from 480 and we're left 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.

Step 7:
When dividing 160 by 58, we get 2 with a remainder of 44.
Record the quotient 2 as the next digit in the result. 
Result so far: 12998.2
The remainder is 44 after subtracting 116 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 8:
When dividing 440 by 58, we get 7 with a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 12998.27
The remainder is 34 after subtracting 406 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 9:
340 divided by 58 is 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 12998.275
The remainder is 50 after subtracting 290 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
58 can be fit into 500 8 times, resulting in a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 12998.2758
Subtracting 464 from 500 leaves us 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.

Moving on to step 11:
If we divide 360 by 58, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 12998.27586
If we take 348 away from 360, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
The number 58 fits into 120 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 12998.275862
If we take 116 away from 120, we end up 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.

Moving on to step 13:
58 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 12998.275862
The remainder is 40 after subtracting 0 from 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:
58 goes into 400 6 times with a remainder of 52.
The number 6 becomes the next digit in our result. 
Result so far: 12998.27586206
The remainder is 52 after subtracting 348 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 12998.27586206 and a remainder of 5.2e-08.
