Let's divide 16938 by 4
We want to divide 16938 by 4.

Step 1:
4 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 4

On to step 2:
16 divided by 4 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 0 after subtracting 16 from 16.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 4

Advancing to step 3:
If we divide 9 by 4, we get 2 and a remainder of 1.
The next digit of our result is 2. 
Result so far: 42.0
The remainder is 1 after subtracting 8 from 9.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 4

Advancing to step 4:
If we divide 13 by 4, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 423.0
Subtract 12 from 13 to get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 4

Moving on to step 5:
If we divide 18 by 4, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 4234.0
If we take 16 away from 18, 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 6:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 4234.5
Subtract 20 from 20 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.

On to step 7:
If we divide 0 by 4, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4234.5
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.

On to step 8:
When dividing 0 by 4, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 4234.5
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.

The final outcome is 4234.5, with a leftover of 0.0.
