We're dividing 475849 by 4 
The aim is to understand the frequency of 4 in 475849.

Step 1:
4 goes into 4 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 4 from 4 to get 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 4

On to step 2:
4 goes into 7 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
If we take 4 away from 7, we end up with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 4

Going ahead to step 3:
35 divided by 4 is 8 with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 118.0
Subtract 32 from 35 to get 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 4

On to step 4:
When dividing 38 by 4, we get 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 1189.0
Subtract 36 from 38 to get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 4

On to step 5:
The number 4 fits into 24 6 times, leaving a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 11896.0
Deduct 24 from 24 and we're left with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 4

Moving on to step 6:
The number 4 fits into 9 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 118962.0
Subtract 8 from 9 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
4 goes into 10 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 118962.2
Subtract 8 from 10 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:
20 divided by 4 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 118962.25
Deduct 20 from 20 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.

Advancing to step 9:
4 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 118962.25
If we subtract 0 from 0, we get 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:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 118962.25
Subtract 0 from 0 to get 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 118962.25, and the remainder is 0.0.
