We look at the division of 15198 by 3 
We want to divide 15198 by 3.

On to step 1:
When dividing 1 by 3, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 3

Advancing to step 2:
3 goes into 15 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 15 from 15, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 3

On to step 3:
The number 3 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 3

Let's proceed to step 4:
3 goes into 19 6 times with a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 506.0
If we take 18 away from 19, we end up with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 3

Let's proceed to step 5:
18 divided by 3 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 5066.0
Deduct 18 from 18 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.

Step 6:
When dividing 0 by 3, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5066.0
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.

Going ahead to step 7:
3 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 5066.0
If we take 0 away from 0, we end up 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.

The quotient of the division is 5066.0, and the remainder is 0.0.
