We look at the division of 85608273 by 851 
The aim is to understand the frequency of 851 in 85608273.

Advancing to step 1:
851 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 851

Moving on to step 2:
If we divide 85 by 851, we get 0 and a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 85 after subtracting 0 from 85.
Append the next digit (6) from the dividend to 85 and continue with: 856 / 851

Going ahead to step 3:
If we divide 856 by 851, we get 1 and a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 851 from 856 leaves us with 5.
Grab the next digit (0) from the dividend, add it to 5, then carry on: 50 / 851

Going ahead to step 4:
If we divide 50 by 851, we get 0 and a remainder of 50.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 50 leaves us with 50.
Take the next digit (8) from the dividend and append it to 50, then repeat: 508 / 851

Moving on to step 5:
When dividing 508 by 851, we get 0 with a remainder of 508.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
Deduct 0 from 508 and we're left with 508.
Bring next digit (2) of the dividend behind the 508 and repeat the process: 5082 / 851

On to step 6:
851 can be fit into 5082 5 times, resulting in a remainder of 827.
The number 5 becomes the next digit in our result. 
Result so far: 1005.0
If we subtract 4255 from 5082, we get 827.
Bring next digit (7) of the dividend behind the 827 and repeat the process: 8277 / 851

Moving on to step 7:
851 can be fit into 8277 9 times, resulting in a remainder of 618.
Use 9 as the next digit of our solution. 
Result so far: 10059.0
The remainder is 618 after subtracting 7659 from 8277.
Fetch the next digit (3) from the dividend, attach it to 618 and continue: 6183 / 851

Advancing to step 8:
When dividing 6183 by 851, we get 7 with a remainder of 226.
Use 7 as the next digit of our solution. 
Result so far: 100597.0
If we subtract 5957 from 6183, we get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 9:
If we divide 2260 by 851, we get 2 and a remainder of 558.
The next digit of our result is 2. 
Result so far: 100597.2
If we take 1702 away from 2260, we end up with 558.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5580, and continue the process.

Going ahead to step 10:
851 can be fit into 5580 6 times, resulting in a remainder of 474.
Put 6 as the next digit of the answer. 
Result so far: 100597.26
If we take 5106 away from 5580, we end up with 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Advancing to step 11:
851 goes into 4740 5 times with a remainder of 485.
Write down 5 as next digit of the result. 
Result so far: 100597.265
Subtracting 4255 from 4740 leaves us with 485.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4850, and continue the process.

Step 12:
851 goes into 4850 5 times with a remainder of 595.
The number 5 becomes the next digit in our result. 
Result so far: 100597.2655
The remainder is 595 after subtracting 4255 from 4850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

The final outcome is 100597.2655, with a leftover of 0.00595.
