We look at the division of 66700945 by 58 
The aim is to understand the frequency of 58 in 66700945.

Step 1:
If we divide 6 by 58, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 58

Let's proceed to step 2:
66 divided by 58 is 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 58 away from 66, we end up with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 58

Step 3:
When dividing 87 by 58, we get 1 with a remainder of 29.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we take 58 away from 87, we end up with 29.
Fetch the next digit (0) from the dividend, attach it to 29 and continue: 290 / 58

Advancing to step 4:
The number 58 fits into 290 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
Subtracting 290 from 290 leaves us with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 58

Going ahead to step 5:
The number 58 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 1150.0
If we take 0 away from 0, we end up with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 58

Step 6:
58 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 11500.0
If we subtract 0 from 9, we get 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 58

Moving on to step 7:
58 goes into 94 1 times with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 115001.0
If we subtract 58 from 94, we get 36.
Bring next digit (5) of the dividend behind the 36 and repeat the process: 365 / 58

Going ahead to step 8:
When dividing 365 by 58, we get 6 with a remainder of 17.
Write down 6 as next digit of the result. 
Result so far: 1150016.0
Subtract 348 from 365 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
The number 58 fits into 170 2 times, leaving a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 1150016.2
The remainder is 54 after subtracting 116 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 10:
58 can be fit into 540 9 times, resulting in a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 1150016.29
Deduct 522 from 540 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 11:
If we divide 180 by 58, we get 3 and a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 1150016.293
If we take 174 away from 180, we end up 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.

Moving on to step 12:
When dividing 60 by 58, we get 1 with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1150016.2931
Subtract 58 from 60 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 13:
58 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 1150016.2931
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 14:
58 can be fit into 200 3 times, resulting in a remainder of 26.
Use 3 as the next digit of our solution. 
Result so far: 1150016.293103
Deduct 174 from 200 and we're left 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.

Let's proceed to step 15:
The number 58 fits into 260 4 times, leaving a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 1150016.2931034
The remainder is 28 after subtracting 232 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 16:
280 divided by 58 is 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 1150016.29310344
If we take 232 away from 280, we end up 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.

Our division results in 1150016.29310344 with a remaining 4.8e-08.
