820607 divided by 4 
The aim is to understand the frequency of 4 in 820607.

Step 1:
4 can be fit into 8 2 times, resulting in a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 8 from 8, we get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 4

Let's proceed to step 2:
If we divide 2 by 4, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 4

On to step 3:
20 divided by 4 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 205.0
Subtracting 20 from 20 leaves us with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 4

Let's proceed to step 4:
When dividing 6 by 4, we get 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 2051.0
Subtract 4 from 6 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 4

Let's proceed to step 5:
20 divided by 4 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 20515.0
Subtracting 20 from 20 leaves us with 0.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 4

On to step 6:
When dividing 7 by 4, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 205151.0
The remainder is 3 after subtracting 4 from 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
4 can be fit into 30 7 times, resulting in a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 205151.7
Subtract 28 from 30 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
If we divide 20 by 4, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 205151.75
If we take 20 away from 20, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 205151.75
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
0 divided by 4 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 205151.75
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 205151.75, and the remainder is 0.0.
