We divide 552158 by 3
The aim is to understand the frequency of 3 in 552158.

Going ahead to step 1:
The number 3 fits into 5 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 3 from 5 to get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 3

On to step 2:
When dividing 25 by 3, we get 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 18.0
Deduct 24 from 25 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 3

Advancing to step 3:
The number 3 fits into 12 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 184.0
If we take 12 away from 12, we end up with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 3

On to step 4:
1 divided by 3 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 1840.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 3

On to step 5:
The number 3 fits into 15 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 18405.0
Subtract 15 from 15 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 3

Step 6:
3 goes into 8 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 184052.0
The remainder is 2 after subtracting 6 from 8.
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 7:
20 divided by 3 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 184052.6
Deduct 18 from 20 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 8:
3 goes into 20 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 184052.66
Subtract 18 from 20 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.

After the division, we end up with 184052.66 and a remainder of 0.002.
