We're dividing 631245 by 58 
The aim is to understand the frequency of 58 in 631245.

Advancing to step 1:
58 goes into 6 0 times with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 58

Moving on to step 2:
58 goes into 63 1 times with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 58 away from 63, we end up with 5.
Bring next digit (1) of the dividend behind the 5 and repeat the process: 51 / 58

On to step 3:
The number 58 fits into 51 0 times, leaving a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 51 and we're left with 51.
Fetch the next digit (2) from the dividend, attach it to 51 and continue: 512 / 58

Let's proceed to step 4:
512 divided by 58 is 8 with a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 108.0
If we take 464 away from 512, we end up with 48.
Grab the next digit (4) from the dividend, add it to 48, then carry on: 484 / 58

Moving on to step 5:
If we divide 484 by 58, we get 8 and a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 1088.0
If we subtract 464 from 484, we get 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 58

Step 6:
205 divided by 58 is 3 with a remainder of 31.
Use 3 as the next digit of our solution. 
Result so far: 10883.0
If we take 174 away from 205, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
58 goes into 310 5 times with a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 10883.5
If we subtract 290 from 310, we 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.

On to step 8:
When dividing 200 by 58, we get 3 with a remainder of 26.
The next digit of our result is 3. 
Result so far: 10883.53
Subtracting 174 from 200 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
When dividing 260 by 58, we get 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 10883.534
If we subtract 232 from 260, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 10:
58 goes into 280 4 times with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 10883.5344
Subtracting 232 from 280 leaves us with 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 10883.5344, with a leftover of 0.00048.
