679850 ÷ 58 
The aim is to understand the frequency of 58 in 679850.

On to step 1:
If we divide 6 by 58, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 58

Advancing to step 2:
The number 58 fits into 67 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 58 from 67 and we're left with 9.
Take the next digit (9) from the dividend and append it to 9, then repeat: 99 / 58

Moving on to step 3:
If we divide 99 by 58, we get 1 and a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 58 from 99 to get 41.
Include the next digit (8) from the dividend after 41, then repeat: 418 / 58

Advancing to step 4:
If we divide 418 by 58, we get 7 and a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 117.0
Subtract 406 from 418 to get 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 58

On to step 5:
125 divided by 58 is 2 with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 1172.0
Subtracting 116 from 125 leaves us with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 58

Moving on to step 6:
The number 58 fits into 90 1 times, leaving a remainder of 32.
Use 1 as the next digit of our solution. 
Result so far: 11721.0
If we subtract 58 from 90, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 7:
58 goes into 320 5 times with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 11721.5
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.

On to step 8:
The number 58 fits into 300 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 11721.55
Subtract 290 from 300 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 11721.55 and a remainder of 0.01.
