We divide 223948 by 3
We want to figure out the number of times 223948 can be divided by 3.

Advancing to step 1:
3 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 3

Advancing to step 2:
The number 3 fits into 22 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 21 from 22 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 3

Moving on to step 3:
3 goes into 13 4 times with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 74.0
Deduct 12 from 13 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 3

Advancing to step 4:
3 goes into 19 6 times with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 746.0
If we subtract 18 from 19, we get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 3

Moving on to step 5:
The number 3 fits into 14 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 7464.0
Subtracting 12 from 14 leaves us with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 3

Advancing to step 6:
If we divide 28 by 3, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 74649.0
If we subtract 27 from 28, we 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.

Step 7:
When dividing 10 by 3, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 74649.3
Subtract 9 from 10 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.

On to step 8:
When dividing 10 by 3, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 74649.33
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 74649.33, and the remainder is 0.001.
