We're dividing 561049 by 85 
The aim is to understand the frequency of 85 in 561049.

Let's proceed to step 1:
If we divide 5 by 85, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 85

Step 2:
When dividing 56 by 85, we get 0 with a remainder of 56.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 56 and we're left with 56.
Append the next digit (1) from the dividend to 56 and continue with: 561 / 85

On to step 3:
When dividing 561 by 85, we get 6 with a remainder of 51.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 510 away from 561, we end up with 51.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 85

On to step 4:
If we divide 510 by 85, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 66.0
The remainder is 0 after subtracting 510 from 510.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 85

Moving on to step 5:
If we divide 4 by 85, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 660.0
If we subtract 0 from 4, we get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 85

Moving on to step 6:
49 divided by 85 is 0 with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 6600.0
If we take 0 away from 49, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 7:
When dividing 490 by 85, we get 5 with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 6600.5
If we subtract 425 from 490, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 8:
650 divided by 85 is 7 with a remainder of 55.
Record the quotient 7 as the next digit in the result. 
Result so far: 6600.57
Subtracting 595 from 650 leaves us 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 9:
85 can be fit into 550 6 times, resulting in a remainder of 40.
The next digit of our result is 6. 
Result so far: 6600.576
If we subtract 510 from 550, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
400 divided by 85 is 4 with a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 6600.5764
If we subtract 340 from 400, we get 60.
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 11:
600 divided by 85 is 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 6600.57647
Deduct 595 from 600 and we're left 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 12:
If we divide 50 by 85, we get 0 and a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 6600.57647
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 13:
When dividing 500 by 85, we get 5 with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 6600.5764705
If we take 425 away from 500, we end up 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.

Step 14:
If we divide 750 by 85, we get 8 and a remainder of 70.
Use 8 as the next digit of our solution. 
Result so far: 6600.57647058
Subtract 680 from 750 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Our division results in 6600.57647058 with a remaining 7e-08.
