125283 divided by 85 
The aim is to understand the frequency of 85 in 125283.

On to step 1:
The number 85 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 85

Moving on to step 2:
The number 85 fits into 12 0 times, leaving a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Bring next digit (5) of the dividend behind the 12 and repeat the process: 125 / 85

On to step 3:
If we divide 125 by 85, we get 1 and a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 40 after subtracting 85 from 125.
Fetch the next digit (2) from the dividend, attach it to 40 and continue: 402 / 85

Let's proceed to step 4:
85 can be fit into 402 4 times, resulting in a remainder of 62.
The next digit of our result is 4. 
Result so far: 14.0
Deduct 340 from 402 and we're left with 62.
Bring next digit (8) of the dividend behind the 62 and repeat the process: 628 / 85

On to step 5:
85 can be fit into 628 7 times, resulting in a remainder of 33.
Record the quotient 7 as the next digit in the result. 
Result so far: 147.0
If we take 595 away from 628, we end up with 33.
Append the next digit (3) from the dividend to 33 and continue with: 333 / 85

Advancing to step 6:
When dividing 333 by 85, we get 3 with a remainder of 78.
Record the quotient 3 as the next digit in the result. 
Result so far: 1473.0
Subtracting 255 from 333 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 7:
The number 85 fits into 780 9 times, leaving a remainder of 15.
Record the quotient 9 as the next digit in the result. 
Result so far: 1473.9
If we take 765 away from 780, we end up 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.

On to step 8:
150 divided by 85 is 1 with a remainder of 65.
The number 1 becomes the next digit in our result. 
Result so far: 1473.91
If we take 85 away from 150, we end up 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.

Moving on to step 9:
When dividing 650 by 85, we get 7 with a remainder of 55.
Record the quotient 7 as the next digit in the result. 
Result so far: 1473.917
If we subtract 595 from 650, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 10:
When dividing 550 by 85, we get 6 with a remainder of 40.
The next digit of our result is 6. 
Result so far: 1473.9176
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.

On to step 11:
400 divided by 85 is 4 with a remainder of 60.
Use 4 as the next digit of our solution. 
Result so far: 1473.91764
Subtract 340 from 400 to 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.

Advancing to step 12:
85 goes into 600 7 times with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 1473.917647
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.

Advancing to step 13:
The number 85 fits into 50 0 times, leaving a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 1473.917647
If we subtract 0 from 50, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 14:
The number 85 fits into 500 5 times, leaving a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 1473.91764705
Subtracting 425 from 500 leaves us 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 final result is 1473.91764705 with a remainder of 7.5e-08.
