63411302 divided by 399 
We want to figure out the number of times 63411302 can be divided by 399.

Step 1:
If we divide 6 by 399, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 399

Step 2:
The number 399 fits into 63 0 times, leaving a remainder of 63.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 63, we get 63.
Fetch the next digit (4) from the dividend, attach it to 63 and continue: 634 / 399

On to step 3:
399 goes into 634 1 times with a remainder of 235.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 399 from 634 leaves us with 235.
Fetch the next digit (1) from the dividend, attach it to 235 and continue: 2351 / 399

Advancing to step 4:
When dividing 2351 by 399, we get 5 with a remainder of 356.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 1995 from 2351, we get 356.
Fetch the next digit (1) from the dividend, attach it to 356 and continue: 3561 / 399

On to step 5:
399 goes into 3561 8 times with a remainder of 369.
Put 8 as the next digit of the answer. 
Result so far: 158.0
Subtracting 3192 from 3561 leaves us with 369.
Grab the next digit (3) from the dividend, add it to 369, then carry on: 3693 / 399

Let's proceed to step 6:
When dividing 3693 by 399, we get 9 with a remainder of 102.
Use 9 as the next digit of our solution. 
Result so far: 1589.0
The remainder is 102 after subtracting 3591 from 3693.
Include the next digit (0) from the dividend after 102, then repeat: 1020 / 399

Let's proceed to step 7:
When dividing 1020 by 399, we get 2 with a remainder of 222.
Write down 2 as next digit of the result. 
Result so far: 15892.0
Deduct 798 from 1020 and we're left with 222.
Bring next digit (2) of the dividend behind the 222 and repeat the process: 2222 / 399

Step 8:
If we divide 2222 by 399, we get 5 and a remainder of 227.
Write down 5 as next digit of the result. 
Result so far: 158925.0
If we take 1995 away from 2222, we end up with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

On to step 9:
399 can be fit into 2270 5 times, resulting in a remainder of 275.
The next digit of our result is 5. 
Result so far: 158925.5
Deduct 1995 from 2270 and we're left with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Going ahead to step 10:
The number 399 fits into 2750 6 times, leaving a remainder of 356.
Use 6 as the next digit of our solution. 
Result so far: 158925.56
Subtract 2394 from 2750 to get 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

On to step 11:
If we divide 3560 by 399, we get 8 and a remainder of 368.
Put 8 as the next digit of the answer. 
Result so far: 158925.568
If we take 3192 away from 3560, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Advancing to step 12:
When dividing 3680 by 399, we get 9 with a remainder of 89.
Write down 9 as next digit of the result. 
Result so far: 158925.5689
Subtract 3591 from 3680 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 13:
If we divide 890 by 399, we get 2 and a remainder of 92.
Use 2 as the next digit of our solution. 
Result so far: 158925.56892
If we take 798 away from 890, we end up with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

On to step 14:
If we divide 920 by 399, we get 2 and a remainder of 122.
The number 2 becomes the next digit in our result. 
Result so far: 158925.568922
Subtract 798 from 920 to get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

The quotient of the division is 158925.568922, and the remainder is 1.22e-05.
