58091092 divided by 578 
The aim is to understand the frequency of 578 in 58091092.

On to step 1:
578 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 578

Advancing to step 2:
578 goes into 58 0 times with a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 58, we get 58.
Include the next digit (0) from the dividend after 58, then repeat: 580 / 578

Going ahead to step 3:
The number 578 fits into 580 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 578 away from 580, we end up with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 578

Step 4:
If we divide 29 by 578, we get 0 and a remainder of 29.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 29 leaves us with 29.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 578

Step 5:
If we divide 291 by 578, we get 0 and a remainder of 291.
Put 0 as the next digit of the answer. 
Result so far: 100.0
If we take 0 away from 291, we end up with 291.
Include the next digit (0) from the dividend after 291, then repeat: 2910 / 578

On to step 6:
If we divide 2910 by 578, we get 5 and a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 1005.0
Subtracting 2890 from 2910 leaves us with 20.
Append the next digit (9) from the dividend to 20 and continue with: 209 / 578

On to step 7:
578 can be fit into 209 0 times, resulting in a remainder of 209.
Write down 0 as next digit of the result. 
Result so far: 10050.0
The remainder is 209 after subtracting 0 from 209.
Grab the next digit (2) from the dividend, add it to 209, then carry on: 2092 / 578

Advancing to step 8:
If we divide 2092 by 578, we get 3 and a remainder of 358.
The next digit of our result is 3. 
Result so far: 100503.0
If we subtract 1734 from 2092, we get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Let's proceed to step 9:
578 goes into 3580 6 times with a remainder of 112.
Write down 6 as next digit of the result. 
Result so far: 100503.6
If we take 3468 away from 3580, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 10:
578 can be fit into 1120 1 times, resulting in a remainder of 542.
The next digit of our result is 1. 
Result so far: 100503.61
If we subtract 578 from 1120, we get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Going ahead to step 11:
The number 578 fits into 5420 9 times, leaving a remainder of 218.
Put 9 as the next digit of the answer. 
Result so far: 100503.619
The remainder is 218 after subtracting 5202 from 5420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 12:
The number 578 fits into 2180 3 times, leaving a remainder of 446.
Put 3 as the next digit of the answer. 
Result so far: 100503.6193
If we take 1734 away from 2180, we end up with 446.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4460, and continue the process.

Going ahead to step 13:
4460 divided by 578 is 7 with a remainder of 414.
The next digit of our result is 7. 
Result so far: 100503.61937
Subtract 4046 from 4460 to get 414.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4140, and continue the process.

Moving on to step 14:
578 goes into 4140 7 times with a remainder of 94.
Use 7 as the next digit of our solution. 
Result so far: 100503.619377
Deduct 4046 from 4140 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

After the division, we end up with 100503.619377 and a remainder of 9.4e-06.
