We're dividing 71214281 by 585 
The aim is to understand the frequency of 585 in 71214281.

Step 1:
7 divided by 585 is 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 585

Moving on to step 2:
585 goes into 71 0 times with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 71 after subtracting 0 from 71.
Fetch the next digit (2) from the dividend, attach it to 71 and continue: 712 / 585

Going ahead to step 3:
If we divide 712 by 585, we get 1 and a remainder of 127.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 585 from 712 to get 127.
Take the next digit (1) from the dividend and append it to 127, then repeat: 1271 / 585

Moving on to step 4:
585 can be fit into 1271 2 times, resulting in a remainder of 101.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we take 1170 away from 1271, we end up with 101.
Take the next digit (4) from the dividend and append it to 101, then repeat: 1014 / 585

Advancing to step 5:
585 can be fit into 1014 1 times, resulting in a remainder of 429.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
The remainder is 429 after subtracting 585 from 1014.
Fetch the next digit (2) from the dividend, attach it to 429 and continue: 4292 / 585

Going ahead to step 6:
If we divide 4292 by 585, we get 7 and a remainder of 197.
The next digit of our result is 7. 
Result so far: 1217.0
If we take 4095 away from 4292, we end up with 197.
Fetch the next digit (8) from the dividend, attach it to 197 and continue: 1978 / 585

Advancing to step 7:
When dividing 1978 by 585, we get 3 with a remainder of 223.
Use 3 as the next digit of our solution. 
Result so far: 12173.0
Subtract 1755 from 1978 to get 223.
Append the next digit (1) from the dividend to 223 and continue with: 2231 / 585

Let's proceed to step 8:
2231 divided by 585 is 3 with a remainder of 476.
The next digit of our result is 3. 
Result so far: 121733.0
The remainder is 476 after subtracting 1755 from 2231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Step 9:
When dividing 4760 by 585, we get 8 with a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 121733.8
Subtracting 4680 from 4760 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 10:
585 goes into 800 1 times with a remainder of 215.
Put 1 as the next digit of the answer. 
Result so far: 121733.81
Subtracting 585 from 800 leaves us with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Going ahead to step 11:
585 goes into 2150 3 times with a remainder of 395.
The number 3 becomes the next digit in our result. 
Result so far: 121733.813
If we take 1755 away from 2150, we end up with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

On to step 12:
3950 divided by 585 is 6 with a remainder of 440.
Write down 6 as next digit of the result. 
Result so far: 121733.8136
Subtracting 3510 from 3950 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 13:
If we divide 4400 by 585, we get 7 and a remainder of 305.
Use 7 as the next digit of our solution. 
Result so far: 121733.81367
Subtract 4095 from 4400 to get 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Going ahead to step 14:
3050 divided by 585 is 5 with a remainder of 125.
Use 5 as the next digit of our solution. 
Result so far: 121733.813675
Deduct 2925 from 3050 and we're left with 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Step 15:
585 goes into 1250 2 times with a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 121733.8136752
Subtract 1170 from 1250 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 16:
If we divide 800 by 585, we get 1 and a remainder of 215.
Use 1 as the next digit of our solution. 
Result so far: 121733.81367521
Deduct 585 from 800 and we're left with 215.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2150, and continue the process.

Our division results in 121733.81367521 with a remaining 2.15e-07.
