We're dividing 79281380 by 399 
Let's see how many times 399 fits into 79281380.

Step 1:
The number 399 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 399

Step 2:
The number 399 fits into 79 0 times, leaving a remainder of 79.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 79 leaves us with 79.
Fetch the next digit (2) from the dividend, attach it to 79 and continue: 792 / 399

Let's proceed to step 3:
If we divide 792 by 399, we get 1 and a remainder of 393.
The next digit of our result is 1. 
Result so far: 1.0
If we take 399 away from 792, we end up with 393.
Grab the next digit (8) from the dividend, add it to 393, then carry on: 3938 / 399

Going ahead to step 4:
399 goes into 3938 9 times with a remainder of 347.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we subtract 3591 from 3938, we get 347.
Grab the next digit (1) from the dividend, add it to 347, then carry on: 3471 / 399

Step 5:
The number 399 fits into 3471 8 times, leaving a remainder of 279.
Use 8 as the next digit of our solution. 
Result so far: 198.0
If we subtract 3192 from 3471, we get 279.
Grab the next digit (3) from the dividend, add it to 279, then carry on: 2793 / 399

Moving on to step 6:
The number 399 fits into 2793 7 times, leaving a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 1987.0
If we take 2793 away from 2793, we end up with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 399

Going ahead to step 7:
The number 399 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 19870.0
If we subtract 0 from 8, we get 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 399

Going ahead to step 8:
399 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 198700.0
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 9:
399 goes into 800 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 198700.2
The remainder is 2 after subtracting 798 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
If we divide 20 by 399, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 198700.2
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 11:
200 divided by 399 is 0 with a remainder of 200.
Record the quotient 0 as the next digit in the result. 
Result so far: 198700.2
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

The quotient of the division is 198700.2, and the remainder is 0.02.
