We're dividing 251213 by 58 
The aim is to understand the frequency of 58 in 251213.

On to step 1:
If we divide 2 by 58, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 58

Let's proceed to step 2:
58 goes into 25 0 times with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 58

Let's proceed to step 3:
When dividing 251 by 58, we get 4 with a remainder of 19.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 232 from 251, we get 19.
Take the next digit (2) from the dividend and append it to 19, then repeat: 192 / 58

Moving on to step 4:
58 can be fit into 192 3 times, resulting in a remainder of 18.
Put 3 as the next digit of the answer. 
Result so far: 43.0
If we subtract 174 from 192, we get 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 58

Let's proceed to step 5:
58 can be fit into 181 3 times, resulting in a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 433.0
Subtracting 174 from 181 leaves us with 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 58

Let's proceed to step 6:
If we divide 73 by 58, we get 1 and a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 4331.0
Subtracting 58 from 73 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
58 goes into 150 2 times with a remainder of 34.
Write down 2 as next digit of the result. 
Result so far: 4331.2
Subtract 116 from 150 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.

Moving on to step 8:
58 goes into 340 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 4331.25
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.

Going ahead to step 9:
When dividing 500 by 58, we get 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 4331.258
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.

Moving on to step 10:
58 can be fit into 360 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 4331.2586
If we subtract 348 from 360, we 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.

Step 11:
When dividing 120 by 58, we get 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 4331.25862
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 12:
If we divide 40 by 58, we get 0 and a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 4331.25862
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.

Step 13:
400 divided by 58 is 6 with a remainder of 52.
Use 6 as the next digit of our solution. 
Result so far: 4331.2586206
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.

Advancing to step 14:
58 goes into 520 8 times with a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 4331.25862068
Subtract 464 from 520 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

After the division, we end up with 4331.25862068 and a remainder of 5.6e-08.
