We're dividing 146486 by 58 
The aim is to understand the frequency of 58 in 146486.

Going ahead to step 1:
1 divided by 58 is 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 58

Moving on to step 2:
58 goes into 14 0 times with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 14, we get 14.
Include the next digit (6) from the dividend after 14, then repeat: 146 / 58

Step 3:
The number 58 fits into 146 2 times, leaving a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 116 from 146 to get 30.
Grab the next digit (4) from the dividend, add it to 30, then carry on: 304 / 58

Step 4:
58 can be fit into 304 5 times, resulting in a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtracting 290 from 304 leaves us with 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 58

On to step 5:
58 can be fit into 148 2 times, resulting in a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 252.0
Deduct 116 from 148 and we're left with 32.
Take the next digit (6) from the dividend and append it to 32, then repeat: 326 / 58

Step 6:
58 can be fit into 326 5 times, resulting in a remainder of 36.
Put 5 as the next digit of the answer. 
Result so far: 2525.0
If we subtract 290 from 326, we get 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 7:
When dividing 360 by 58, we get 6 with a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 2525.6
Subtracting 348 from 360 leaves us 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 8:
When dividing 120 by 58, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 2525.62
Subtract 116 from 120 to 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.

On to step 9:
When dividing 40 by 58, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 2525.62
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.

Advancing to step 10:
The number 58 fits into 400 6 times, leaving a remainder of 52.
Record the quotient 6 as the next digit in the result. 
Result so far: 2525.6206
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.

Going ahead to step 11:
520 divided by 58 is 8 with a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 2525.62068
If we take 464 away from 520, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 12:
58 can be fit into 560 9 times, resulting in a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 2525.620689
If we take 522 away from 560, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 13:
58 can be fit into 380 6 times, resulting in a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 2525.6206896
Subtracting 348 from 380 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 14:
If we divide 320 by 58, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 2525.62068965
The remainder is 30 after subtracting 290 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 2525.62068965 and a remainder of 3e-08.
