79862955 divided by 399 
Our goal is to divide 79862955 by 399.

Advancing to step 1:
When dividing 7 by 399, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 399

Going ahead to step 2:
399 goes into 79 0 times with a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Fetch the next digit (8) from the dividend, attach it to 79 and continue: 798 / 399

Moving on to step 3:
399 goes into 798 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 0 after subtracting 798 from 798.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 399

Let's proceed to step 4:
The number 399 fits into 6 0 times, leaving a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 399

Advancing to step 5:
399 can be fit into 62 0 times, resulting in a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 200.0
Deduct 0 from 62 and we're left with 62.
Include the next digit (9) from the dividend after 62, then repeat: 629 / 399

Step 6:
399 goes into 629 1 times with a remainder of 230.
Use 1 as the next digit of our solution. 
Result so far: 2001.0
Subtract 399 from 629 to get 230.
Take the next digit (5) from the dividend and append it to 230, then repeat: 2305 / 399

Advancing to step 7:
399 can be fit into 2305 5 times, resulting in a remainder of 310.
The number 5 becomes the next digit in our result. 
Result so far: 20015.0
If we take 1995 away from 2305, we end up with 310.
Fetch the next digit (5) from the dividend, attach it to 310 and continue: 3105 / 399

Let's proceed to step 8:
3105 divided by 399 is 7 with a remainder of 312.
The next digit of our result is 7. 
Result so far: 200157.0
If we subtract 2793 from 3105, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Let's proceed to step 9:
399 can be fit into 3120 7 times, resulting in a remainder of 327.
Put 7 as the next digit of the answer. 
Result so far: 200157.7
Deduct 2793 from 3120 and we're left with 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Going ahead to step 10:
The number 399 fits into 3270 8 times, leaving a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 200157.78
Subtracting 3192 from 3270 leaves us with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 11:
When dividing 780 by 399, we get 1 with a remainder of 381.
Put 1 as the next digit of the answer. 
Result so far: 200157.781
If we take 399 away from 780, we end up with 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Advancing to step 12:
The number 399 fits into 3810 9 times, leaving a remainder of 219.
The next digit of our result is 9. 
Result so far: 200157.7819
Deduct 3591 from 3810 and we're left with 219.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2190, and continue the process.

Advancing to step 13:
2190 divided by 399 is 5 with a remainder of 195.
Use 5 as the next digit of our solution. 
Result so far: 200157.78195
Subtract 1995 from 2190 to get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

Going ahead to step 14:
1950 divided by 399 is 4 with a remainder of 354.
Use 4 as the next digit of our solution. 
Result so far: 200157.781954
If we take 1596 away from 1950, we end up with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Advancing to step 15:
If we divide 3540 by 399, we get 8 and a remainder of 348.
Put 8 as the next digit of the answer. 
Result so far: 200157.7819548
Subtract 3192 from 3540 to get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Going ahead to step 16:
3480 divided by 399 is 8 with a remainder of 288.
Put 8 as the next digit of the answer. 
Result so far: 200157.78195488
If we take 3192 away from 3480, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

The final outcome is 200157.78195488, with a leftover of 2.88e-07.
