We look at the division of 77413301 by 399 
We're looking to find how many times 399 goes into 77413301.

Moving on to step 1:
If we divide 7 by 399, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 399

Step 2:
399 can be fit into 77 0 times, resulting in a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Grab the next digit (4) from the dividend, add it to 77, then carry on: 774 / 399

Moving on to step 3:
If we divide 774 by 399, we get 1 and a remainder of 375.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 399 from 774 to get 375.
Take the next digit (1) from the dividend and append it to 375, then repeat: 3751 / 399

On to step 4:
3751 divided by 399 is 9 with a remainder of 160.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Deduct 3591 from 3751 and we're left with 160.
Bring next digit (3) of the dividend behind the 160 and repeat the process: 1603 / 399

On to step 5:
When dividing 1603 by 399, we get 4 with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 194.0
Subtracting 1596 from 1603 leaves us with 7.
Grab the next digit (3) from the dividend, add it to 7, then carry on: 73 / 399

Let's proceed to step 6:
The number 399 fits into 73 0 times, leaving a remainder of 73.
Use 0 as the next digit of our solution. 
Result so far: 1940.0
The remainder is 73 after subtracting 0 from 73.
Include the next digit (0) from the dividend after 73, then repeat: 730 / 399

Step 7:
399 goes into 730 1 times with a remainder of 331.
Use 1 as the next digit of our solution. 
Result so far: 19401.0
If we take 399 away from 730, we end up with 331.
Grab the next digit (1) from the dividend, add it to 331, then carry on: 3311 / 399

Advancing to step 8:
If we divide 3311 by 399, we get 8 and a remainder of 119.
Write down 8 as next digit of the result. 
Result so far: 194018.0
If we subtract 3192 from 3311, we get 119.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1190, and continue the process.

Step 9:
399 goes into 1190 2 times with a remainder of 392.
Write down 2 as next digit of the result. 
Result so far: 194018.2
Subtracting 798 from 1190 leaves us with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Going ahead to step 10:
The number 399 fits into 3920 9 times, leaving a remainder of 329.
The next digit of our result is 9. 
Result so far: 194018.29
Subtract 3591 from 3920 to get 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Going ahead to step 11:
399 can be fit into 3290 8 times, resulting in a remainder of 98.
Record the quotient 8 as the next digit in the result. 
Result so far: 194018.298
Deduct 3192 from 3290 and we're left with 98.
Since there are no more digits in the dividend, we add a zero to the remainder making it 980, and continue the process.

Moving on to step 12:
If we divide 980 by 399, we get 2 and a remainder of 182.
The next digit of our result is 2. 
Result so far: 194018.2982
If we subtract 798 from 980, we get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

On to step 13:
399 can be fit into 1820 4 times, resulting in a remainder of 224.
Write down 4 as next digit of the result. 
Result so far: 194018.29824
Deduct 1596 from 1820 and we're left with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 14:
The number 399 fits into 2240 5 times, leaving a remainder of 245.
The next digit of our result is 5. 
Result so far: 194018.298245
Subtract 1995 from 2240 to get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Advancing to step 15:
2450 divided by 399 is 6 with a remainder of 56.
The next digit of our result is 6. 
Result so far: 194018.2982456
The remainder is 56 after subtracting 2394 from 2450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 16:
560 divided by 399 is 1 with a remainder of 161.
Put 1 as the next digit of the answer. 
Result so far: 194018.29824561
The remainder is 161 after subtracting 399 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1610, and continue the process.

The quotient of the division is 194018.29824561, and the remainder is 1.61e-07.
