We divide 684139 by 85
The aim is to understand the frequency of 85 in 684139.

On to step 1:
The number 85 fits into 6 0 times, leaving a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 85

Going ahead to step 2:
If we divide 68 by 85, we get 0 and a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Bring next digit (4) of the dividend behind the 68 and repeat the process: 684 / 85

Going ahead to step 3:
If we divide 684 by 85, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtract 680 from 684 to get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 85

Step 4:
The number 85 fits into 41 0 times, leaving a remainder of 41.
The next digit of our result is 0. 
Result so far: 80.0
The remainder is 41 after subtracting 0 from 41.
Fetch the next digit (3) from the dividend, attach it to 41 and continue: 413 / 85

Advancing to step 5:
When dividing 413 by 85, we get 4 with a remainder of 73.
Record the quotient 4 as the next digit in the result. 
Result so far: 804.0
If we subtract 340 from 413, we get 73.
Take the next digit (9) from the dividend and append it to 73, then repeat: 739 / 85

Let's proceed to step 6:
When dividing 739 by 85, we get 8 with a remainder of 59.
Use 8 as the next digit of our solution. 
Result so far: 8048.0
Subtracting 680 from 739 leaves us with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 7:
When dividing 590 by 85, we get 6 with a remainder of 80.
The next digit of our result is 6. 
Result so far: 8048.6
Deduct 510 from 590 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 8:
If we divide 800 by 85, we get 9 and a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 8048.69
Subtract 765 from 800 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 9:
The number 85 fits into 350 4 times, leaving a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 8048.694
Subtract 340 from 350 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
When dividing 100 by 85, we get 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 8048.6941
Deduct 85 from 100 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 11:
The number 85 fits into 150 1 times, leaving a remainder of 65.
Write down 1 as next digit of the result. 
Result so far: 8048.69411
Subtract 85 from 150 to 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.

The final outcome is 8048.69411, with a leftover of 6.5e-05.
