We look at the division of 85108985 by 839 
The aim is to understand the frequency of 839 in 85108985.

On to step 1:
839 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 839

Moving on to step 2:
839 can be fit into 85 0 times, resulting in a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Grab the next digit (1) from the dividend, add it to 85, then carry on: 851 / 839

On to step 3:
851 divided by 839 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 839 away from 851, we end up with 12.
Include the next digit (0) from the dividend after 12, then repeat: 120 / 839

On to step 4:
839 goes into 120 0 times with a remainder of 120.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 120, we end up with 120.
Take the next digit (8) from the dividend and append it to 120, then repeat: 1208 / 839

Let's proceed to step 5:
839 can be fit into 1208 1 times, resulting in a remainder of 369.
Put 1 as the next digit of the answer. 
Result so far: 101.0
If we take 839 away from 1208, we end up with 369.
Grab the next digit (9) from the dividend, add it to 369, then carry on: 3699 / 839

Step 6:
The number 839 fits into 3699 4 times, leaving a remainder of 343.
Write down 4 as next digit of the result. 
Result so far: 1014.0
Deduct 3356 from 3699 and we're left with 343.
Fetch the next digit (8) from the dividend, attach it to 343 and continue: 3438 / 839

Step 7:
839 can be fit into 3438 4 times, resulting in a remainder of 82.
Write down 4 as next digit of the result. 
Result so far: 10144.0
Subtract 3356 from 3438 to get 82.
Take the next digit (5) from the dividend and append it to 82, then repeat: 825 / 839

On to step 8:
If we divide 825 by 839, we get 0 and a remainder of 825.
Record the quotient 0 as the next digit in the result. 
Result so far: 101440.0
Subtract 0 from 825 to get 825.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8250, and continue the process.

Let's proceed to step 9:
8250 divided by 839 is 9 with a remainder of 699.
Put 9 as the next digit of the answer. 
Result so far: 101440.9
The remainder is 699 after subtracting 7551 from 8250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6990, and continue the process.

Going ahead to step 10:
6990 divided by 839 is 8 with a remainder of 278.
Use 8 as the next digit of our solution. 
Result so far: 101440.98
If we take 6712 away from 6990, we end up with 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

On to step 11:
2780 divided by 839 is 3 with a remainder of 263.
Put 3 as the next digit of the answer. 
Result so far: 101440.983
The remainder is 263 after subtracting 2517 from 2780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Let's proceed to step 12:
839 goes into 2630 3 times with a remainder of 113.
Put 3 as the next digit of the answer. 
Result so far: 101440.9833
Deduct 2517 from 2630 and we're left with 113.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1130, and continue the process.

In conclusion, the division gives 101440.9833 with a balance of 0.00113.
