2108153 ÷ 851 
The aim is to understand the frequency of 851 in 2108153.

Let's proceed to step 1:
The number 851 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 851

On to step 2:
851 goes into 21 0 times with a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Take the next digit (0) from the dividend and append it to 21, then repeat: 210 / 851

Going ahead to step 3:
851 goes into 210 0 times with a remainder of 210.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 210 and we're left with 210.
Bring next digit (8) of the dividend behind the 210 and repeat the process: 2108 / 851

Let's proceed to step 4:
2108 divided by 851 is 2 with a remainder of 406.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1702 away from 2108, we end up with 406.
Fetch the next digit (1) from the dividend, attach it to 406 and continue: 4061 / 851

Let's proceed to step 5:
851 can be fit into 4061 4 times, resulting in a remainder of 657.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Deduct 3404 from 4061 and we're left with 657.
Include the next digit (5) from the dividend after 657, then repeat: 6575 / 851

On to step 6:
If we divide 6575 by 851, we get 7 and a remainder of 618.
Write down 7 as next digit of the result. 
Result so far: 247.0
Subtracting 5957 from 6575 leaves us with 618.
Fetch the next digit (3) from the dividend, attach it to 618 and continue: 6183 / 851

Going ahead to step 7:
When dividing 6183 by 851, we get 7 with a remainder of 226.
Write down 7 as next digit of the result. 
Result so far: 2477.0
The remainder is 226 after subtracting 5957 from 6183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Advancing to step 8:
If we divide 2260 by 851, we get 2 and a remainder of 558.
The number 2 becomes the next digit in our result. 
Result so far: 2477.2
If we subtract 1702 from 2260, we get 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 9:
5580 divided by 851 is 6 with a remainder of 474.
Put 6 as the next digit of the answer. 
Result so far: 2477.26
If we subtract 5106 from 5580, we get 474.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4740, and continue the process.

Let's proceed to step 10:
If we divide 4740 by 851, we get 5 and a remainder of 485.
Write down 5 as next digit of the result. 
Result so far: 2477.265
If we take 4255 away from 4740, we end up 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.

Going ahead to step 11:
4850 divided by 851 is 5 with a remainder of 595.
Write down 5 as next digit of the result. 
Result so far: 2477.2655
If we subtract 4255 from 4850, we get 595.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5950, and continue the process.

The quotient of the division is 2477.2655, and the remainder is 0.00595.
