211646 ÷ 3 
The aim is to understand the frequency of 3 in 211646.

Step 1:
The number 3 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 3

Going ahead to step 2:
If we divide 21 by 3, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 21 from 21 to get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 3

Advancing to step 3:
3 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 70.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 3

Going ahead to step 4:
3 goes into 16 5 times with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 705.0
Subtract 15 from 16 to get 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 3

Step 5:
3 goes into 14 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 7054.0
If we subtract 12 from 14, we get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 3

Going ahead to step 6:
When dividing 26 by 3, we get 8 with a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 70548.0
If we take 24 away from 26, we end up 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.

Advancing to step 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 70548.6
If we take 18 away from 20, we end up 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.

Step 8:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 70548.66
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 70548.66, and the remainder is 0.002.
