5250148 ÷ 585 
The aim is to understand the frequency of 585 in 5250148.

On to step 1:
When dividing 5 by 585, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 585

Let's proceed to step 2:
When dividing 52 by 585, we get 0 with a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 52, we get 52.
Fetch the next digit (5) from the dividend, attach it to 52 and continue: 525 / 585

Step 3:
585 goes into 525 0 times with a remainder of 525.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 525, we get 525.
Grab the next digit (0) from the dividend, add it to 525, then carry on: 5250 / 585

Advancing to step 4:
585 goes into 5250 8 times with a remainder of 570.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 4680 from 5250, we get 570.
Take the next digit (1) from the dividend and append it to 570, then repeat: 5701 / 585

Advancing to step 5:
The number 585 fits into 5701 9 times, leaving a remainder of 436.
Write down 9 as next digit of the result. 
Result so far: 89.0
Subtracting 5265 from 5701 leaves us with 436.
Grab the next digit (4) from the dividend, add it to 436, then carry on: 4364 / 585

Step 6:
When dividing 4364 by 585, we get 7 with a remainder of 269.
Put 7 as the next digit of the answer. 
Result so far: 897.0
If we subtract 4095 from 4364, we get 269.
Take the next digit (8) from the dividend and append it to 269, then repeat: 2698 / 585

Moving on to step 7:
585 can be fit into 2698 4 times, resulting in a remainder of 358.
Write down 4 as next digit of the result. 
Result so far: 8974.0
If we take 2340 away from 2698, we end up with 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Step 8:
585 goes into 3580 6 times with a remainder of 70.
Use 6 as the next digit of our solution. 
Result so far: 8974.6
The remainder is 70 after subtracting 3510 from 3580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
If we divide 700 by 585, we get 1 and a remainder of 115.
Record the quotient 1 as the next digit in the result. 
Result so far: 8974.61
If we take 585 away from 700, we end up with 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Advancing to step 10:
585 goes into 1150 1 times with a remainder of 565.
Put 1 as the next digit of the answer. 
Result so far: 8974.611
Subtract 585 from 1150 to get 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

The quotient of the division is 8974.611, and the remainder is 0.0565.
