66658547 ÷ 585 
The aim is to understand the frequency of 585 in 66658547.

On to step 1:
585 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 585

Advancing to step 2:
When dividing 66 by 585, we get 0 with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Append the next digit (6) from the dividend to 66 and continue with: 666 / 585

Let's proceed to step 3:
666 divided by 585 is 1 with a remainder of 81.
The next digit of our result is 1. 
Result so far: 1.0
If we take 585 away from 666, we end up with 81.
Take the next digit (5) from the dividend and append it to 81, then repeat: 815 / 585

Advancing to step 4:
585 can be fit into 815 1 times, resulting in a remainder of 230.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 585 away from 815, we end up with 230.
Grab the next digit (8) from the dividend, add it to 230, then carry on: 2308 / 585

Moving on to step 5:
When dividing 2308 by 585, we get 3 with a remainder of 553.
Write down 3 as next digit of the result. 
Result so far: 113.0
If we take 1755 away from 2308, we end up with 553.
Bring next digit (5) of the dividend behind the 553 and repeat the process: 5535 / 585

On to step 6:
5535 divided by 585 is 9 with a remainder of 270.
Write down 9 as next digit of the result. 
Result so far: 1139.0
The remainder is 270 after subtracting 5265 from 5535.
Bring next digit (4) of the dividend behind the 270 and repeat the process: 2704 / 585

On to step 7:
585 can be fit into 2704 4 times, resulting in a remainder of 364.
Write down 4 as next digit of the result. 
Result so far: 11394.0
If we take 2340 away from 2704, we end up with 364.
Include the next digit (7) from the dividend after 364, then repeat: 3647 / 585

Step 8:
When dividing 3647 by 585, we get 6 with a remainder of 137.
Use 6 as the next digit of our solution. 
Result so far: 113946.0
Deduct 3510 from 3647 and we're left with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Advancing to step 9:
The number 585 fits into 1370 2 times, leaving a remainder of 200.
Use 2 as the next digit of our solution. 
Result so far: 113946.2
Deduct 1170 from 1370 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 10:
585 can be fit into 2000 3 times, resulting in a remainder of 245.
Record the quotient 3 as the next digit in the result. 
Result so far: 113946.23
Subtracting 1755 from 2000 leaves us with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 11:
When dividing 2450 by 585, we get 4 with a remainder of 110.
The number 4 becomes the next digit in our result. 
Result so far: 113946.234
Subtracting 2340 from 2450 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 12:
When dividing 1100 by 585, we get 1 with a remainder of 515.
Record the quotient 1 as the next digit in the result. 
Result so far: 113946.2341
Deduct 585 from 1100 and we're left with 515.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5150, and continue the process.

Let's proceed to step 13:
If we divide 5150 by 585, we get 8 and a remainder of 470.
Write down 8 as next digit of the result. 
Result so far: 113946.23418
The remainder is 470 after subtracting 4680 from 5150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Going ahead to step 14:
4700 divided by 585 is 8 with a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 113946.234188
If we subtract 4680 from 4700, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 113946.234188 and a remainder of 2e-06.
