We're dividing 69003849 by 399 
Our goal is to divide 69003849 by 399.

Step 1:
399 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 399

Going ahead to step 2:
399 can be fit into 69 0 times, resulting in a remainder of 69.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Fetch the next digit (0) from the dividend, attach it to 69 and continue: 690 / 399

Moving on to step 3:
399 goes into 690 1 times with a remainder of 291.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 291 after subtracting 399 from 690.
Grab the next digit (0) from the dividend, add it to 291, then carry on: 2910 / 399

Advancing to step 4:
399 goes into 2910 7 times with a remainder of 117.
Write down 7 as next digit of the result. 
Result so far: 17.0
The remainder is 117 after subtracting 2793 from 2910.
Include the next digit (3) from the dividend after 117, then repeat: 1173 / 399

Let's proceed to step 5:
1173 divided by 399 is 2 with a remainder of 375.
The number 2 becomes the next digit in our result. 
Result so far: 172.0
Subtract 798 from 1173 to get 375.
Include the next digit (8) from the dividend after 375, then repeat: 3758 / 399

Moving on to step 6:
When dividing 3758 by 399, we get 9 with a remainder of 167.
Use 9 as the next digit of our solution. 
Result so far: 1729.0
If we subtract 3591 from 3758, we get 167.
Fetch the next digit (4) from the dividend, attach it to 167 and continue: 1674 / 399

Step 7:
When dividing 1674 by 399, we get 4 with a remainder of 78.
The next digit of our result is 4. 
Result so far: 17294.0
If we take 1596 away from 1674, we end up with 78.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 399

Step 8:
When dividing 789 by 399, we get 1 with a remainder of 390.
Record the quotient 1 as the next digit in the result. 
Result so far: 172941.0
Subtracting 399 from 789 leaves us with 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Step 9:
399 goes into 3900 9 times with a remainder of 309.
The number 9 becomes the next digit in our result. 
Result so far: 172941.9
Subtracting 3591 from 3900 leaves us with 309.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3090, and continue the process.

Moving on to step 10:
The number 399 fits into 3090 7 times, leaving a remainder of 297.
Put 7 as the next digit of the answer. 
Result so far: 172941.97
Subtract 2793 from 3090 to get 297.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2970, and continue the process.

Moving on to step 11:
399 goes into 2970 7 times with a remainder of 177.
The number 7 becomes the next digit in our result. 
Result so far: 172941.977
Deduct 2793 from 2970 and we're left with 177.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1770, and continue the process.

The quotient of the division is 172941.977, and the remainder is 0.0177.
