We look at the division of 612668 by 58 
The aim is to understand the frequency of 58 in 612668.

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
If we subtract 0 from 6, we get 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 58

Moving on to step 2:
If we divide 61 by 58, we get 1 and a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 58 from 61 to get 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 58

Advancing to step 3:
58 goes into 32 0 times with a remainder of 32.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 32 leaves us with 32.
Fetch the next digit (6) from the dividend, attach it to 32 and continue: 326 / 58

Moving on to step 4:
58 goes into 326 5 times with a remainder of 36.
Record the quotient 5 as the next digit in the result. 
Result so far: 105.0
If we take 290 away from 326, we end up with 36.
Take the next digit (6) from the dividend and append it to 36, then repeat: 366 / 58

Moving on to step 5:
When dividing 366 by 58, we get 6 with a remainder of 18.
Write down 6 as next digit of the result. 
Result so far: 1056.0
The remainder is 18 after subtracting 348 from 366.
Grab the next digit (8) from the dividend, add it to 18, then carry on: 188 / 58

On to step 6:
The number 58 fits into 188 3 times, leaving a remainder of 14.
Put 3 as the next digit of the answer. 
Result so far: 10563.0
Subtracting 174 from 188 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
When dividing 140 by 58, we get 2 with a remainder of 24.
The next digit of our result is 2. 
Result so far: 10563.2
Deduct 116 from 140 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
If we divide 240 by 58, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 10563.24
If we take 232 away from 240, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
58 goes into 80 1 times with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 10563.241
Subtracting 58 from 80 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
58 goes into 220 3 times with a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 10563.2413
If we subtract 174 from 220, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 11:
460 divided by 58 is 7 with a remainder of 54.
Record the quotient 7 as the next digit in the result. 
Result so far: 10563.24137
Subtracting 406 from 460 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 12:
58 goes into 540 9 times with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 10563.241379
Subtract 522 from 540 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 13:
58 can be fit into 180 3 times, resulting in a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 10563.2413793
Deduct 174 from 180 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 14:
58 can be fit into 60 1 times, resulting in a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 10563.24137931
Subtracting 58 from 60 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 10563.24137931 with a remaining 2e-09.
