85389316 divided by 581 
The aim is to understand the frequency of 581 in 85389316.

Advancing to step 1:
8 divided by 581 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 581

Step 2:
If we divide 85 by 581, we get 0 and a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Grab the next digit (3) from the dividend, add it to 85, then carry on: 853 / 581

Going ahead to step 3:
When dividing 853 by 581, we get 1 with a remainder of 272.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 581 away from 853, we end up with 272.
Grab the next digit (8) from the dividend, add it to 272, then carry on: 2728 / 581

Advancing to step 4:
If we divide 2728 by 581, we get 4 and a remainder of 404.
Put 4 as the next digit of the answer. 
Result so far: 14.0
The remainder is 404 after subtracting 2324 from 2728.
Fetch the next digit (9) from the dividend, attach it to 404 and continue: 4049 / 581

Step 5:
The number 581 fits into 4049 6 times, leaving a remainder of 563.
The next digit of our result is 6. 
Result so far: 146.0
Deduct 3486 from 4049 and we're left with 563.
Include the next digit (3) from the dividend after 563, then repeat: 5633 / 581

Let's proceed to step 6:
581 can be fit into 5633 9 times, resulting in a remainder of 404.
The number 9 becomes the next digit in our result. 
Result so far: 1469.0
If we take 5229 away from 5633, we end up with 404.
Bring next digit (1) of the dividend behind the 404 and repeat the process: 4041 / 581

On to step 7:
If we divide 4041 by 581, we get 6 and a remainder of 555.
Write down 6 as next digit of the result. 
Result so far: 14696.0
Subtract 3486 from 4041 to get 555.
Include the next digit (6) from the dividend after 555, then repeat: 5556 / 581

Moving on to step 8:
581 can be fit into 5556 9 times, resulting in a remainder of 327.
The next digit of our result is 9. 
Result so far: 146969.0
If we take 5229 away from 5556, we end up with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

On to step 9:
When dividing 3270 by 581, we get 5 with a remainder of 365.
Use 5 as the next digit of our solution. 
Result so far: 146969.5
Deduct 2905 from 3270 and we're left with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Step 10:
When dividing 3650 by 581, we get 6 with a remainder of 164.
Use 6 as the next digit of our solution. 
Result so far: 146969.56
Subtracting 3486 from 3650 leaves us with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

On to step 11:
581 goes into 1640 2 times with a remainder of 478.
Write down 2 as next digit of the result. 
Result so far: 146969.562
Subtracting 1162 from 1640 leaves us with 478.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

On to step 12:
If we divide 4780 by 581, we get 8 and a remainder of 132.
Use 8 as the next digit of our solution. 
Result so far: 146969.5628
Deduct 4648 from 4780 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 13:
581 can be fit into 1320 2 times, resulting in a remainder of 158.
Use 2 as the next digit of our solution. 
Result so far: 146969.56282
Subtract 1162 from 1320 to get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Let's proceed to step 14:
1580 divided by 581 is 2 with a remainder of 418.
Use 2 as the next digit of our solution. 
Result so far: 146969.562822
Deduct 1162 from 1580 and we're left with 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4180, and continue the process.

In conclusion, the division gives 146969.562822 with a balance of 4.18e-05.
