80712134 ÷ 85 
The aim is to understand the frequency of 85 in 80712134.

Let's proceed to step 1:
8 divided by 85 is 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 85

Let's proceed to step 2:
85 can be fit into 80 0 times, resulting in a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Bring next digit (7) of the dividend behind the 80 and repeat the process: 807 / 85

Advancing to step 3:
The number 85 fits into 807 9 times, leaving a remainder of 42.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 765 from 807 to get 42.
Include the next digit (1) from the dividend after 42, then repeat: 421 / 85

Let's proceed to step 4:
85 goes into 421 4 times with a remainder of 81.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
If we take 340 away from 421, we end up with 81.
Take the next digit (2) from the dividend and append it to 81, then repeat: 812 / 85

Advancing to step 5:
85 goes into 812 9 times with a remainder of 47.
Put 9 as the next digit of the answer. 
Result so far: 949.0
If we take 765 away from 812, we end up with 47.
Fetch the next digit (1) from the dividend, attach it to 47 and continue: 471 / 85

Let's proceed to step 6:
If we divide 471 by 85, we get 5 and a remainder of 46.
Put 5 as the next digit of the answer. 
Result so far: 9495.0
If we subtract 425 from 471, we get 46.
Grab the next digit (3) from the dividend, add it to 46, then carry on: 463 / 85

Going ahead to step 7:
The number 85 fits into 463 5 times, leaving a remainder of 38.
Put 5 as the next digit of the answer. 
Result so far: 94955.0
Deduct 425 from 463 and we're left with 38.
Bring next digit (4) of the dividend behind the 38 and repeat the process: 384 / 85

Step 8:
When dividing 384 by 85, we get 4 with a remainder of 44.
Write down 4 as next digit of the result. 
Result so far: 949554.0
Deduct 340 from 384 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
When dividing 440 by 85, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 949554.5
Deduct 425 from 440 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
If we divide 150 by 85, we get 1 and a remainder of 65.
The next digit of our result is 1. 
Result so far: 949554.51
Subtracting 85 from 150 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

On to step 11:
650 divided by 85 is 7 with a remainder of 55.
Write down 7 as next digit of the result. 
Result so far: 949554.517
Deduct 595 from 650 and we're left with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 12:
85 can be fit into 550 6 times, resulting in a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 949554.5176
If we take 510 away from 550, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
85 goes into 400 4 times with a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 949554.51764
The remainder is 60 after subtracting 340 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 14:
When dividing 600 by 85, we get 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 949554.517647
Subtracting 595 from 600 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 15:
85 goes into 50 0 times with a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 949554.517647
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 16:
500 divided by 85 is 5 with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 949554.51764705
Deduct 425 from 500 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

The quotient of the division is 949554.51764705, and the remainder is 7.5e-08.
